As Spain experiences a violent climate shock and successive heat waves that have broken records, protecting street workers is no longer limited to providing water and sun umbrellas. The city of Barcelona has decided to turn to technology to save lives, and has already begun distributing advanced smart bracelets to workers in open areas, serving as an 'early warning system' that intervenes in the last seconds before a health disaster occurs.

The extraordinary step came after terrifying reports revealed more than 1,000 excess deaths above the normal rate during the month of June alone, due to the insane rise in temperatures that hit the country.

Technology Saves Lives on the Street

Barcelona has distributed about 1,400 smart bracelets to the most vulnerable employees due to their work under the scorching sun, whose daily tasks involve strenuous physical effort outdoors, namely:

Street and public square cleaners.

Lighting and electrical network maintenance teams.

Garden and public park workers.

Waste management sector employees.

The bracelet's mechanism is highly precise, as the device continuously monitors the worker's body temperature and vital signs in real time. If the bracelet senses that body temperature is beginning to rise to levels that pose an imminent threat to life (such as a fatal heatstroke), it immediately emits violent vibrations and sharp alarm sounds. At that moment, the safety protocol requires the worker to stop work immediately and take refuge in the nearest shaded area.

These strict measures did not come out of nowhere; Spain has witnessed in the past few years tragic incidents of several street workers dying while on duty due to excessive heat stress, which sparked public anger and forced authorities to completely change work patterns and conditions.

Pep Limona, prevention coordinator at the Barcelona Parks and Gardens Department, explained to local media that these bracelets are part of a comprehensive plan to adapt to climate change that has become 'severe and terrifyingly increasing'.

Complicating matters further, the Spanish Meteorological Agency announced that last June was the second hottest month since climate data recording began in the country's history, confirming that Spanish cities are preparing for a second, more intense heat wave starting at the beginning of the week, making these smart bracelets the last line of defense between workers and silent death under the sun's rays.
