Hitzerisiko am Arbeitsplatz: Barcelona verteilt 1.400 Warnbänder

As summer temperatures climb to dangerous levels, governments and employers across the globe are introducing new measures to protect outdoor workers from heat stress. From wearable technology in Europe to mandatory workplace rules in the Middle East, the push to safeguard millions of employees in construction, delivery, and sanitation is intensifying.

Barcelona deploys wearable heat alerts

In Spain, Barcelona’s municipal authorities have distributed 1,400 wearable heat-alert wristbands to outdoor workers, including gardeners and street cleaners. The devices monitor body temperature and sound an alarm when an individual's internal heat reaches a level that signals a high risk of heat stress.

But technology alone can’t cover every gap—many UK employers still lack the basic risk assessments and safety documentation that regulators check first. Without these records, a business can face substantial fines, even if it has invested in gadgets. A free Health & Safety Toolkit provides ready-to-use risk assessments, checklists, and toolbox talks that help you document your safety measures properly. Download the free Health & Safety Toolkit

The initiative follows a period in June when extreme heat contributed to more than 1,000 excess deaths across Spain. The wristbands are part of a growing trend toward using technology to prevent heat-related illness before it becomes critical.

UAE mandates five-point summer safety plan

The United Arab Emirates has taken a regulatory approach. The Ministry of Human Resources and Emiratisation has ordered employers to implement five specific safety measures for outdoor staff during the summer season.

Companies must now provide cold drinking water, hydration supplies, and access to shaded rest areas. The directive also requires the installation of industrial cooling systems and the availability of first aid resources at work sites to reduce the impact of rising temperatures.

US: A patchwork of protections

The regulatory landscape for heat protection in the United States remains fragmented, with states moving in different directions.

In late June, New York City Mayor Eric Adams signed an executive order requiring the development of heat illness prevention plans for approximately 1.4 million outdoor workers. Detroit Mayor Mike Duggan followed with a policy implemented on July 1 that halts water shutoffs whenever temperatures exceed 90 degrees Fahrenheit.

However, the federal Occupational Safety and Health Administration (OSHA) has yet to establish a nationwide heat standard, though rulemaking is ongoing. This gap coincides with legislative moves in Texas and Florida, where state-level bans on local heat protection requirements were enacted in 2023 and 2024 respectively.

While states such as California, Oregon, and Minnesota have established their own protections, workers elsewhere remain dependent on voluntary employer practices.

India’s informal workforce left exposed

In India, current Heat Action Plans (HAPs) have been criticised for failing to cover the country's vast informal workforce. Reports indicate that 90% of informal workers are not protected by existing safety frameworks.

In Delhi alone, approximately 5 million street vendors and construction workers lack occupation-specific measures to combat extreme heat. Researchers have called for a social inclusion framework that involves community co-design to better protect these vulnerable populations.

Agricultural sector turns to education

In the agricultural sector, organisations are focusing on training to close safety gaps. The North Carolina State Extension has launched workshops in both English and Spanish through its Agricultural Workforce Health and Safety Education Program.

The sessions emphasise the importance of shaded rest, regular breaks, and the ability to recognise early signs of heat illness — basic protections that can make the difference between a safe shift and a medical emergency.

As heat safety rules multiply worldwide, UK employers must also ensure they meet the legal duties set out in the Health & Safety at Work Act 1974. Failing to produce adequate risk assessments or emergency plans can leave a business exposed to enforcement action. A free toolkit with 9 ready-to-use tools—including risk assessments, checklists, and a director’s liability guide—helps you stay compliant. Get the free Health & Safety at Work Act 1974 Toolkit

Rest stations and local alerts

In China, millions of delivery and sanitation workers have been granted access to dedicated rest stations, providing essential relief during peak heat hours.

In the United States, local health officials are highlighting the physiological signs of heat exhaustion — cramps, fatigue, and swelling. Dr James Black, an emergency room physician in Georgia, stressed the importance of avoiding peak heat hours and maintaining hydration.

Meanwhile, municipal alerts in New Jersey have targeted public employees, including firefighters and sanitation workers, through safety notifications that require employers to monitor the heat index and provide mandatory breaks when conditions become hazardous.
