Barcelona is introducing wearable heat-monitoring bracelets for thousands of outdoor employees in a major step aimed at improving worker safety as Spain continues to battle increasingly dangerous summer temperatures.
The initiative comes as the country experiences one of its hottest starts to summer on record, with repeated heatwaves placing millions of people at risk. City officials hope the technology will help prevent heat-related illnesses by alerting workers before their bodies reach dangerous levels of heat stress.
Approximately 1,400 bracelets are being distributed to employees whose jobs require them to spend long hours outdoors. The devices are being worn by street cleaners, park maintenance teams, waste collection workers, lighting crews and other municipal employees who face prolonged exposure to the sun during their daily duties.
The smart bracelets continuously monitor the wearer’s body temperature. If the device detects signs that the worker may be overheating or is at risk of heat exhaustion or heatstroke, it immediately issues both an audible alarm and a vibration. Once the warning is triggered, workers are instructed to stop what they are doing, move into the shade, cool down and follow the city’s heat safety procedures before returning to work.
Barcelona officials say the program is part of a broader strategy to adapt to the growing effects of climate change, which has made heatwaves more frequent, more intense and longer-lasting across southern Europe. City authorities believe technology can play an important role in reducing workplace injuries and saving lives as temperatures continue to rise year after year.
Pep Llimona, prevention coordinator for Barcelona’s parks and gardens service, said the city has been preparing measures to better protect workers as climate conditions become increasingly severe. According to him, the wearable devices provide an additional layer of protection by identifying early warning signs before workers themselves may realise they are in danger.
The move also follows heightened concern over several heat-related deaths involving outdoor workers across Spain in recent years. Those tragedies have prompted employers and local governments to reassess working conditions during periods of extreme heat.
One incident that deeply affected Barcelona occurred last June when a 51-year-old street cleaner died after completing her work shift in the city’s historic centre on a day when temperatures climbed above 30 degrees Celsius. Although city officials later said there was no evidence that heatstroke was the confirmed cause of death, the incident sparked widespread discussion about worker safety during extreme weather.
Llimona explained that plans to introduce the bracelets had already been underway before the worker’s death. However, the tragedy accelerated the city’s efforts and reinforced the urgency of implementing stronger protections for employees working outdoors.
Spain has been enduring an exceptionally hot summer, with the national weather agency reporting that June was the country’s second-hottest June ever recorded. Meteorologists have warned that another major heatwave is expected to sweep across large parts of the country in the coming days, bringing even higher temperatures.
As climate change continues to push temperatures to new extremes, local governments are increasingly being forced to rethink how outdoor work is carried out. Many employers have already adjusted work schedules by shifting physically demanding tasks to cooler morning hours, increasing rest breaks and providing more water, shade and cooling equipment.
For supervisors responsible for worker safety, the challenge is becoming greater every year. Brigade supervisor Ester Jimenez said rising temperatures have made protecting staff one of her biggest concerns. She noted that assigning daily tasks now requires constant attention to weather conditions because the risk of heatstroke has become a growing reality.
Barcelona hopes its new wearable technology will become an important tool in preventing future tragedies. By combining real-time health monitoring with existing workplace safety measures, city leaders aim to ensure that outdoor employees can continue carrying out essential public services while reducing the dangers posed by increasingly extreme summer heat.
The initiative reflects a growing recognition across Europe that adapting to climate change is no longer a future challenge but an immediate necessity, particularly for workers whose jobs place them on the front lines of rising temperatures every day.
