    Legislative Updates – 10JUL26

    1. European Union – New Push for Heat Stress Legislation

    The most significant development has come from Europe, where trade unions and Members of the European Parliament are increasing pressure on the European Commission to introduce legally binding workplace heat protections as part of the forthcoming Quality Jobs Act.

    What’s being proposed?

    Rather than relying on ambient air temperature, proposals are centred on Wet Bulb Globe Temperature (WBGT), which provides a more accurate measure of heat stress by considering:

    • Air temperature
    • Humidity
    • Solar radiation
    • Air movement

    The draft proposals include:

    • Mandatory heat risk assessments.
    • Employer duties to provide drinking water and shaded rest areas.
    • Additional rest breaks.
    • Adjusted working hours during extreme heat.
    • Suspension of work above specified WBGT thresholds depending on workload.
    • Enforcement powers and penalties for non-compliance.

    Why this matters?

    If adopted, this would represent one of the most significant changes to European workplace health legislation in many years.

    Unlike fixed temperature limits, WBGT acknowledges that 35°C in dry conditions presents a different physiological risk to 35°C with high humidity, making it a far more practical regulatory tool.

    Global implications

    Even organisations outside Europe should pay attention.

    Multinational organisations frequently adopt the highest regulatory standard across all operations rather than maintaining different regional standards.

    I would not be surprised if Australia, New Zealand, Singapore and parts of North America eventually consider similar approaches.

    2. United Kingdom – Heat Risk Moving Up the Regulatory Agenda

    Although no new legislation has been introduced, recent HSE messaging and wider policy discussions indicate that workplace heat is becoming an increasing regulatory priority.

    Current developments include:

    • renewed HSE guidance reminding employers that heat is a foreseeable workplace hazard;
    • continued calls from the Trades Union Congress (TUC) for maximum workplace temperatures; and
    • recommendations from the Climate Change Committee encouraging stronger protections against heat exposure.

    Practical impact

    Businesses should not wait for legislation before reviewing:

    • heat stress risk assessments;
    • hydration arrangements;
    • work scheduling;
    • rest facilities;
    • emergency response to heat illness.

    This is particularly relevant for:

    • Construction
    • Warehousing
    • Manufacturing
    • Utilities
    • Agriculture
    • Emergency services

    3. Great Britain – Latest Workplace Fatality Statistics Published

    While not a legislative amendment, the HSE published its latest annual workplace fatality statistics on 1 July 2026, reporting 126 worker fatalities in Great Britain during 2025/26.

    Although the publication itself does not change legal duties, these statistics often influence:

    • inspection priorities;
    • enforcement campaigns;
    • future guidance;
    • consultation topics.

    Historically, areas experiencing persistent fatality trends receive increased regulatory attention.

    Why organisations should care

    Expect continued HSE focus on:

    • falls from height;
    • vehicle movements;
    • construction;
    • agriculture;
    • manufacturing;
    • workplace transport.

    4. European Focus on Climate Adaptation and Worker Protection

    Another emerging trend is that workplace safety is increasingly being discussed alongside climate adaptation rather than solely occupational health.

    The conversation is expanding beyond:

    “How do we protect workers today?”

    towards

    “How do organisations continue operating safely in a changing climate?”

    This includes discussion around:

    • heat resilience;
    • emergency planning;
    • infrastructure;
    • work scheduling;
    • occupational health surveillance.

    This represents a noticeable shift in regulatory thinking.

    5. Increasing Focus on Psychosocial and Organisational Risk

    Although there have been no major legislative announcements during the past nine days, regulators continue to reinforce expectations around:

    • psychosocial hazards;
    • work-related stress;
    • organisational culture;
    • leadership.

    This remains an area where many jurisdictions—including Australia and the UK—are moving from guidance towards stronger enforcement under existing legal duties.

    Incidents

    1. Ammonium Nitrate Truck Explosion – Inner Mongolia, China

    Date of Incident: 5 July 2026

    Two people were killed and four others injured after a truck transporting ammonium nitrate was involved in a collision on National Highway 331 in East Ujimqin Banner, Inner Mongolia. According to Chinese authorities, the collision resulted in a fire followed by a significant explosion involving the hazardous cargo. Emergency services attended the scene and transported the injured to hospital while the highway was closed during the response.

    Authorities have confirmed that the vehicle was transporting ammonium nitrate, but the precise circumstances leading to the collision remain under investigation. Investigators are expected to examine the sequence of events leading to the crash, compliance with dangerous goods transport regulations, vehicle condition, cargo securing arrangements and emergency response procedures. Ammonium nitrate has been involved in numerous major industrial disasters worldwide, and although this incident appears to have resulted from a road traffic collision rather than a failure of the product itself, it serves as an important reminder of the risks associated with transporting hazardous materials on public roads and the need for robust controls throughout the logistics chain.

    2. Seven Workers Killed in Quarry Rock Collapse – Karnataka, India

    Date of Incident: 2 July 2026

    Seven quarry workers were killed and at least six others injured after a massive rock collapse at a stone quarry in Ramanagara district near Bengaluru, Karnataka. Emergency services carried out an extensive rescue operation after a large boulder detached from the quarry face and fell onto workers below. Initial reports indicate the collapse occurred during active quarrying operations, with those injured transported to nearby hospitals for treatment.

    Authorities have launched an investigation into the circumstances surrounding the collapse, including whether quarrying operations complied with safety requirements and whether excavation activities contributed to the instability of the rock face. Preliminary reports suggest investigators are examining the possible involvement of heavy machinery operating near the edge of the quarry immediately before the collapse. The investigation is also expected to consider geotechnical assessments, exclusion zones, supervision of quarry activities and the management of ground stability hazards. Rockfalls remain one of the most significant causes of fatal injuries within quarrying and surface mining, making this incident highly relevant to organisations involved in extractive industries worldwide.

    3. Three Workers Killed in Septic Tank Collapse – Jaipur, India

    Date of Incident: 29 June 2026

    Three construction workers, including two women, were killed and three others injured when the wall of an under-construction septic tank collapsed at a hotel construction site in Jaipur, Rajasthan. Emergency responders recovered the trapped workers from the excavation and transported the injured to hospital while authorities secured the site.

    Investigators have commenced enquiries into the design and construction of the temporary works supporting the excavation, as well as site supervision and work planning. The incident is expected to focus attention on excavation safety, structural stability during construction, temporary works design and the adequacy of risk assessments for confined excavation activities. Construction collapses of this nature continue to demonstrate the importance of ensuring partially completed structures are capable of safely supporting anticipated loads throughout every stage of construction.

    4. Boundary Wall Collapse at World Trade Centre Construction Site – Gujarat, India

    Date of Incident: 1 July 2026

    Two members of the public were killed after a boundary wall surrounding the under-construction World Trade Centre project in Bharuch, Gujarat, collapsed onto a neighbouring residential property during heavy rainfall. The collapse occurred while severe weather affected the region, with emergency services responding to recover the victims and secure the area.

    Although the fatalities were members of the public rather than construction workers, the incident arose directly from construction activities and has prompted an investigation into site management, drainage arrangements and the structural stability of temporary works during adverse weather. Authorities are expected to examine whether adequate precautions had been taken to protect neighbouring properties and members of the public from construction-related hazards. The incident highlights the importance of considering risks extending beyond the site boundary when planning and managing construction projects.

    Investigation Updates

    5. Investigation Continues into Fatal Ras Laffan LNG Explosion – Qatar

    Date of Incident: 22 June 2026

    Investigators continue to examine the fatal explosion and subsequent fire at the Barzan gas processing facility within Ras Laffan Industrial City, where 13 workers lost their lives and more than 60 others were injured. The incident occurred during the recommissioning of the facility following an extended maintenance shutdown, making it one of the most significant industrial accidents reported globally this year. Qatar Energy has confirmed that LNG export operations elsewhere within Ras Laffan were not affected.

    Authorities have confirmed that the explosion resulted from a technical accident and have ruled out sabotage. The investigation is focusing on plant restart procedures, mechanical integrity, process safety management and equipment performance during commissioning activities. Although no official root cause has yet been released, the incident is expected to become a significant case study in pre-start-up safety reviews, management of change, asset integrity and the risks associated with restarting complex process facilities following prolonged maintenance outages.

    6. Investigation Continues Following Fatal Ammonia Leak – Tamil Nadu, India

    Date of Incident: 21 June 2026

    Authorities continue investigating the fatal ammonia leak at a seafood processing facility in Tamil Nadu, where five workers died and dozens of others were exposed to the toxic release. Emergency services evacuated the area while specialist teams worked to isolate the leak and prevent further exposure. The incident has renewed attention on the risks associated with industrial refrigeration systems that utilise ammonia as a refrigerant.

    Current enquiries are examining the integrity of the refrigeration plant, maintenance practices, hazardous substance management and emergency response arrangements. Investigators are also expected to review gas detection systems, maintenance records, emergency isolation procedures and operator training. Given the widespread use of ammonia refrigeration throughout the food processing, cold storage and logistics industries, the findings are likely to have broad relevance across multiple industrial sectors.

    7. Molten Steel Eruption Investigation Ongoing – Visakhapatnam, India

    Date of Incident: Mid-June 2026

    Investigators continue to examine the fatal molten steel eruption at a major steel manufacturing facility in Visakhapatnam, where nine workers lost their lives during casting operations. The incident occurred while molten steel was being processed, resulting in a catastrophic release of molten metal that fatally injured workers in the immediate vicinity.

    Although the official cause has not yet been established, investigators are reportedly examining operational procedures, process controls and equipment used during steel production. Particular attention is expected to focus on whether critical operating parameters were maintained throughout the casting process and whether appropriate safeguards were in place to prevent uncontrolled releases of molten metal. The investigation is expected to provide valuable lessons for organisations operating high-temperature industrial processes where even minor deviations from established procedures can have catastrophic consequences.

    8. Hanwha Aerospace Rocket Propellant Explosion Investigation Continues – South Korea

    Date of Incident: 1 June 2026

    South Korean authorities continue investigating the explosion at Hanwha Aerospace’s Daejeon facility, where five workers were killed and two others seriously injured while cleaning rocket propellant residue from propulsion components. The explosion occurred inside a dedicated cleaning building before rapidly developing into a fire that caused extensive damage to the facility.

    Investigators are examining the handling of energetic materials, cleaning procedures, engineering controls and compliance with workplace safety requirements. Although no official cause has been released, enquiries are expected to focus on the management of non-routine work, the safe removal of explosive residues, equipment design and process safety management. The investigation has attracted considerable international interest due to the specialist nature of the work and the broader lessons it may provide for industries managing energetic or highly hazardous materials.

    Regulatory & Industry Developments

    9. Singapore Calls Nationwide Safety Time-Out Following Workplace Fatalities

    Reported: Late June 2026

    Singapore’s Ministry of Manpower and the Workplace Safety and Health Council have called for a nationwide voluntary Safety Time-Out following five separate workplace accidents that resulted in seven worker fatalities over a four-week period. Employers across higher-risk industries have been encouraged to pause work temporarily to review critical risks, verify existing controls and reinforce safe systems of work before continuing operations.

    The initiative reflects Singapore’s proactive approach to workplace safety and demonstrates how regulators can respond rapidly when fatality trends begin to deteriorate. Particular emphasis has been placed on leadership commitment, management of routine work activities and ensuring that critical controls remain effective. Rather than introducing immediate regulatory change, authorities are encouraging organisations to use the Safety Time-Out as an opportunity to reassess workplace risks before further serious incidents occur.

    10. Extreme Heat Continues to Challenge Employers Across Europe

    Reported: Throughout Late June and Early July 2026

    Record-breaking temperatures across much of Europe continue to affect workers employed in construction, agriculture, utilities, logistics and other outdoor industries. Temperatures exceeding 40°C in several countries have resulted in revised working hours, additional hydration breaks, increased welfare provisions and, in some cases, temporary suspension of outdoor work during the hottest parts of the day.

    Although not linked to a single workplace incident, the continuing heatwave has become one of the most significant occupational health issues currently affecting Europe. Employers are increasingly reviewing heat stress management plans, acclimatisation arrangements and emergency response procedures for heat-related illness. The prolonged period of extreme temperatures serves as a reminder that environmental conditions themselves can become significant workplace hazards requiring the same level of planning and risk management as more traditional occupational risks.

    Prosecutions & Court Proceedings

    11. Singapore Authorities Appeal Sentence Following Fatal Port Worker Incident

    Development Reported: Late June 2026

    Singaporean authorities have lodged an appeal seeking a higher penalty following a previous fatal workplace incident involving maintenance activities at PSA Singapore’s container terminal. Although the fatality itself occurred several years earlier, the latest legal proceedings have renewed attention on one of the country’s most significant machinery entrapment cases involving maintenance work on a rubber-tyred gantry crane.

    The appeal is expected to further examine whether adequate safety management systems, engineering controls and operational supervision were implemented to protect workers during hazardous maintenance activities. The case continues to provide valuable lessons regarding machine isolation, contractor management, safe maintenance procedures and the importance of eliminating worker exposure to moving machinery wherever reasonably practicable.

    12. UK Construction Company Faces Enforcement Following Heavy Vehicle Incident

    Development Reported: 26 June 2026

    The UK’s Health and Safety Executive has announced enforcement action relating to a serious construction incident in which a 20-tonne tipper truck left an excavation ramp, resulting in significant injuries to the driver. Although the incident itself occurred previously, the enforcement action highlights the continuing regulatory focus on the safe operation of heavy mobile plant within construction environments.

    The proceedings are expected to examine traffic management arrangements, excavation design, operator supervision and site planning. Heavy vehicle incidents remain one of the leading causes of serious injuries and fatalities within the construction industry, and the case reinforces the importance of robust planning, competent supervision and effective separation between vehicles and work activities.

    13. Coroner Refers Orchard Worker Fatality to WorkSafe New Zealand

    Development Reported: 26 June 2026

    A coroner has formally referred the death of an orchard worker in the Bay of Plenty back to WorkSafe New Zealand after identifying significant workplace safety concerns arising from the fatal incident. The worker died while operating an all-terrain vehicle after colliding with a tractor during routine agricultural operations.

    The coroner concluded that the worker was not wearing either a helmet or a seatbelt and indicated that appropriate head protection would likely have prevented the fatal injuries sustained. The referral requests WorkSafe to consider whether further regulatory action is warranted regarding the employer’s management of vehicle safety, supervision and the implementation of basic risk controls. The case highlights the continuing risks associated with agricultural vehicle operations and the importance of ensuring fundamental safety measures remain consistently applied in rural workplaces.

  • How Hot is Too Hot?

    How Hot is Too Hot?

    Heat Is No Longer Just a Summer Problem: Why UK Businesses Need to Rethink Workplace Heat Risk

    For decades, workplace heat in the UK has largely been viewed as an occasional inconvenience—a few uncomfortable days each summer requiring little more than extra water and open windows. That perception is rapidly changing.

    Record-breaking temperatures, more frequent heatwaves and growing evidence linking extreme heat to workplace illness, accidents and productivity losses are pushing heat stress higher up the regulatory agenda. While the UK still has no legal maximum workplace temperature, recent developments suggest the conversation is shifting from “How hot is too hot?” to “How should employers manage heat as a foreseeable workplace hazard?”

    For businesses, the message is becoming increasingly clear: heat is no longer an exceptional event—it is a foreseeable operational risk.

    A Changing Regulatory Landscape

    The UK’s existing legal framework already requires employers to protect workers from risks associated with excessive heat.

    Under the Management of Health and Safety at Work Regulations 1999, employers must assess workplace risks and implement reasonably practicable control measures. The Health and Safety Executive (HSE) has reinforced that this duty applies equally to extreme weather events such as heatwaves.

    Importantly, the HSE has again emphasised that:

    • there is no legal maximum workplace temperature;
    • heat should be treated like any other workplace hazard;
    • employers are expected to undertake suitable risk assessments; and
    • controls should be implemented wherever workers may be exposed to excessive heat.

    Rather than introducing a fixed temperature limit, the regulator continues to promote a risk-based approach, recognising that 30°C in an air-conditioned office presents a very different level of risk to 30°C on a construction site while wearing PPE.

    Pressure for Reform Is Growing

    Although the law has not yet changed, pressure for reform is increasing.

    The Climate Change Committee (CCC) recently recommended that the Government consider introducing maximum workplace temperature regulations as part of the UK’s wider climate adaptation strategy. The Committee believes such regulations would better protect workers while encouraging investment in cooling measures and climate resilience.

    At the same time, trade unions—including the Trades Union Congress (TUC)—continue to campaign for legal temperature thresholds. Their proposals include:

    • employers taking additional action once temperatures exceed 24°C where workers are uncomfortable;
    • allowing workers undertaking strenuous activity to stop work at 27°C; and
    • a general maximum indoor workplace temperature of 30°C.

    These proposals have not been adopted by the Government, but they illustrate the direction of travel.

    Parliament Is Asking Bigger Questions

    The recent UK heatwave has intensified political attention.

    Parliamentarians have questioned whether the UK remains adequately prepared for increasingly frequent periods of extreme heat, with discussions extending beyond public health to include worker protection, overheating in buildings and workplace temperature standards.

    While ministers have not announced plans to introduce maximum legal workplace temperatures, the issue is now firmly part of the national conversation.

    For employers, waiting until legislation changes may prove short-sighted.

    Why This Matters for Businesses

    Heat affects far more than worker comfort.

    Research consistently shows that excessive heat can:

    • reduce concentration and decision-making;
    • increase fatigue;
    • slow reaction times;
    • increase the likelihood of human error;
    • reduce productivity; and
    • contribute to heat exhaustion or, in severe cases, heat stroke.

    These effects are particularly significant where workers operate:

    • heavy machinery;
    • vehicles;
    • cranes;
    • mobile plant;
    • hazardous processes;
    • confined spaces; or
    • environments requiring extensive PPE.

    Many workplace incidents traditionally attributed to “human error” may, in reality, be influenced by fatigue or reduced cognitive performance associated with excessive heat.

    Which Industries Will Feel the Greatest Impact?

    Some sectors are naturally more exposed than others.

    These include:

    • Construction
    • Manufacturing
    • Warehousing
    • Agriculture
    • Utilities
    • Emergency Services
    • Transport and Logistics
    • Mining and Quarrying
    • Oil and Gas
    • Waste and Recycling

    However, heat stress is no longer confined to outdoor work.

    Modern office buildings, schools, hospitals, distribution centres and care facilities are increasingly experiencing overheating during prolonged hot weather.

    The question is no longer whether workers are outside—it is whether their working environment allows their bodies to regulate temperature effectively.

    What Should Employers Be Doing Now?

    Although legislation has not fundamentally changed, HSE guidance provides a clear indication of what good practice looks like.

    Employers should consider:

    • reviewing heat-related risk assessments before summer rather than during a heatwave;
    • identifying workers particularly vulnerable to heat stress;
    • providing cool drinking water and encouraging hydration;
    • increasing the frequency of rest breaks;
    • providing shaded or cooled rest areas;
    • adjusting work schedules to cooler parts of the day where practicable;
    • reviewing PPE requirements;
    • improving ventilation where possible; and
    • training supervisors to recognise the early signs of heat-related illness.

    These measures are generally inexpensive but can significantly reduce both health risks and operational disruption.

    Looking Ahead

    Climate projections suggest hotter summers are likely to become more common across the UK.

    Whether or not the Government ultimately introduces maximum workplace temperature legislation, regulatory expectations are already evolving.

    The HSE is placing increasing emphasis on proactive heat risk management rather than reactive responses once temperatures become extreme. At the same time, policymakers are considering whether existing legislation remains adequate for a changing climate.

    Forward-thinking organisations are therefore beginning to treat heat as they would any other foreseeable workplace hazard—identifying risks, implementing practical controls and continually reviewing their effectiveness.

    Final Thoughts

    For many years, UK employers have viewed heat as an occasional challenge rather than a strategic health and safety issue. That mindset is changing.

    The question is no longer whether another severe heatwave will occur—it is when.

    Businesses that begin adapting now are likely to be better positioned to protect their workers, maintain productivity and respond confidently to future regulatory expectations. Whether or not new legislation introduces maximum workplace temperatures, one principle is already clear:

    Heat is becoming a permanent workplace risk, and organisations that manage it proactively will be far better prepared for the future.

  • Legislative Updates – 03JUL26

    Legislative Updates – 03JUL26

    1. European Union – Agreement Reached on New Worker Protection Standards

    This is probably the most significant development globally during the past week.

    The European Parliament and the Council of the European Union reached a provisional political agreement on the sixth revision of the Carcinogens, Mutagens and Reprotoxic Substances Directive (CMRD).

    Key changes

    The agreement introduces:

    • New occupational exposure limits (OELs) for:
      • Cobalt and inorganic cobalt compounds
      • Polycyclic aromatic hydrocarbons (PAHs)
      • 1,4-Dioxane
      • Isoprene
    • Welding fumes formally recognised within the Directive.
    • Stronger requirements regarding PPE use.
    • Requirements for regular breaks where workers must wear PPE for prolonged periods.
    • Transitional arrangements for industries affected by new exposure limits.

    Why it matters

    If adopted, employers throughout the EU will need to:

    • review COSHH-equivalent assessments,
    • reassess airborne exposure monitoring,
    • review ventilation systems,
    • update health surveillance programmes,
    • review PPE requirements.

    This is a very significant development for manufacturing, construction, mining, foundries, metal fabrication and chemical industries.

    2. United Kingdom – Final Week of the RIDDOR Consultation

    The UK’s consultation on proposed reforms to RIDDOR closes on 30 June 2026, making this the final opportunity for businesses and safety professionals to influence the future reporting framework.

    The proposals include:

    • clearer reporting requirements,
    • revised dangerous occurrence definitions,
    • updated occupational disease reporting,
    • allowing diagnoses from a wider range of health professionals,
    • reducing unnecessary reporting burden.

    Why it matters

    Any organisation operating in the UK should consider whether the proposals adequately capture:

    • high-potential incidents,
    • emerging occupational diseases,
    • process safety events.

    As we’ve discussed previously, this consultation presents an opportunity to modernise UK incident reporting.

    3. Brazil – New Psychosocial Risk Requirements Now in Force

    Brazil’s revised Regulatory Norm No. 1 (NR-1) has now come into force, requiring employers to formally identify and manage psychosocial risks within their occupational risk management programmes.

    Employers must now assess hazards such as:

    • excessive workload,
    • workplace stress,
    • harassment,
    • organisational factors,
    • mental health risks.

    Although regulators have indicated they will initially focus on education rather than enforcement, this represents one of the more significant legislative shifts towards psychological health in the workplace.

    4. European Parliament Begins Discussion on the Post-2027 EU OSH Strategy

    The European Parliament has begun discussions on the next EU Strategic Framework on Health and Safety at Work, which will replace the current strategy after 2027.

    Key emerging themes include:

    • occupational disease prevention,
    • mental health,
    • artificial intelligence,
    • climate change,
    • heat stress,
    • occupational cancers.

    While this is not yet legislation, it provides a clear indication of where future European regulation is heading.

    5. UK – Heat Stress Becomes a Major Regulatory Focus

    Although no new legislation has been introduced, several official bodies have issued updated guidance during the recent heatwave, including:

    • UK Health Security Agency,
    • HSE,
    • Acas.

    The renewed guidance reinforces employer duties to manage heat stress through risk assessment, hydration, rest breaks, ventilation and flexible working where appropriate.

    At the same time, trade unions have renewed calls for legally enforceable maximum workplace temperatures, but no legislative proposal has yet been adopted.

  • Heatwaves: Why Europe Is Struggling While Other Regions Keep Working?

    Heatwaves: Why Europe Is Struggling While Other Regions Keep Working?

    As temperatures soar across the UK and much of Europe, the conversation has shifted beyond uncomfortable commutes and crowded beaches. For millions of workers, the current heatwave is creating genuine health and safety challenges that many employers are unaccustomed to managing.

    Across parts of Europe, temperatures have exceeded 40°C (104°F), while the UK has recorded its hottest June temperatures on record, prompting red extreme heat warnings and widespread disruption. Construction projects have been rescheduled, agricultural work has been curtailed, transport infrastructure has been affected and emergency services have experienced unprecedented demand. Scientists estimate that more than 1,300 excess deaths have already occurred across Europe during the current heatwave, with France alone reporting around 1,000 additional deaths during the most intense period. While the majority of these deaths involve elderly or vulnerable people, the figures highlight the significant health impacts that prolonged extreme heat can have on entire populations.

    Heat Is a Workplace Hazard

    Unlike many traditional workplace hazards, heat cannot always be eliminated. For workers in construction, agriculture, logistics, manufacturing, utilities and emergency services, work must often continue despite challenging environmental conditions.

    The human body functions best within a relatively narrow temperature range. As air temperature and humidity rise, the body’s ability to cool itself through sweating becomes less effective. Without adequate hydration, rest and cooling opportunities, workers can experience heat cramps, heat exhaustion and, in severe cases, heat stroke—a medical emergency that can rapidly become fatal.

    Heat also affects cognitive performance. Research has consistently shown that increasing temperatures reduce concentration, slow reaction times and impair decision-making. In high-risk industries where workers operate heavy machinery, work at height or manage hazardous processes, even minor reductions in alertness can significantly increase the likelihood of an incident.

    The economic impact is also becoming more apparent. Recent analysis suggests that even a four-day heatwave can measurably reduce labour productivity across Western Europe, particularly in construction, manufacturing and agriculture, where much of the work takes place outdoors or in environments with significant heat exposure.

    Why Europe Is Different

    One question frequently asked is why temperatures that are considered routine in other parts of the world cause such significant disruption across Europe.

    The answer is not simply the temperature itself.

    It is preparation and conditioning.

    Workers in regions such as Western Australia and Central Queensland, parts of the Middle East, and many countries across sub-Saharan Africa routinely work in temperatures exceeding 35–40°C. Industries such as mining, construction, oil and gas, agriculture and infrastructure have developed comprehensive systems for managing heat exposure because extreme heat is an expected part of daily operations.

    These measures commonly include:

    • Starting work before sunrise and finishing before the hottest part of the day.
    • Mandatory hydration programmes.
    • Scheduled rest breaks in air-conditioned or shaded recovery areas.
    • Heat acclimatisation programmes for new workers.
    • Monitoring environmental conditions using heat stress indices such as the Wet Bulb Globe Temperature (WBGT).
    • Supervising workers for early signs of heat-related illness.
    • Adjusting workloads based on temperature and humidity.

    Importantly, workers themselves are also physiologically acclimatised to hot conditions. Heat acclimatisation develops over approximately one to two weeks of regular exposure and improves the body’s ability to regulate temperature, sweat more efficiently and maintain cardiovascular performance during physical work.

    By comparison, prolonged periods above 30°C remain relatively uncommon across much of northern Europe and the UK. Many workplaces have limited cooling infrastructure, buildings are often designed to retain heat rather than dissipate it, and both employers and workers may have relatively little experience managing sustained high-temperature conditions.

    Acclimatisation Is Not Immunity

    While acclimatisation significantly improves heat tolerance, it does not eliminate the risk.

    Every year, countries accustomed to extreme temperatures continue to experience heat-related illnesses and fatalities. In Australia’s mining and construction sectors, employers routinely implement comprehensive heat management plans despite operating in climates where summer temperatures frequently exceed 40°C.

    Similarly, workers in equatorial Africa often adapt their working practices around the climate rather than attempting to work through the hottest part of the day. In many regions, physical work naturally slows during the afternoon before resuming as temperatures begin to fall.

    The lesson is clear: successful hot-weather working is not simply about “being used to it”. It is about recognising heat as a workplace hazard and managing it accordingly.

    A Growing Challenge

    Heatwaves are becoming more frequent, more intense and longer lasting. The World Health Organization estimates that approximately 489,000 heat-related deaths occur globally each year, while Europe experienced an estimated 61,672 heat-related excess deaths during the summer of 2022 alone. Even the cooler summer of 2023 was associated with an estimated 47,000 heat-related deaths across Europe.

    As temperatures continue to rise, organisations may need to rethink how work is planned during periods of extreme heat. Measures that were once considered exceptional—earlier start times, flexible shifts, mandatory hydration breaks and formal heat stress management plans—may become standard practice in many industries.

    What Can Employers Do?

    Organisations should ensure that heat risks are considered within their risk assessments and that appropriate controls are implemented before temperatures reach dangerous levels. Practical measures include:

    • Monitoring weather forecasts and heat alerts.
    • Providing cool drinking water and encouraging frequent hydration.
    • Introducing additional rest breaks and shaded recovery areas.
    • Scheduling physically demanding work during cooler parts of the day.
    • Gradually acclimatising workers returning from leave or new to hot environments.
    • Training supervisors to recognise the early signs of heat-related illness.
    • Reviewing emergency response procedures for suspected heat stroke.

    Final Thoughts

    The current heatwave is a reminder that weather itself can become a significant workplace hazard. While countries with consistently hot climates have developed systems to manage these risks, much of Europe is still adapting to a future in which extreme heat may become increasingly common.

    Experience from around the world demonstrates that people can work safely in very hot conditions—but only when the risks are recognised, workers are properly acclimatised, and appropriate controls are in place.

    For employers, the challenge is no longer simply responding to an unusually hot summer. It is preparing for a future where extreme heat becomes another foreseeable workplace hazard requiring the same level of planning, leadership and risk management as any other.
