How to anticipate and safeguard employees’ health during periods of intense heat?

Published on : 29/07/2026 29 July Jul 07 2026

DO

• Take proactive measures as soon as weather warnings are issued: activate a ‘heatwave’ plan as soon as a heatwave is forecast (adjustments to work organisation, refreshment arrangements, work equipment, information and guidance).

• Make practical adjustments to working practices, particularly for outdoor work: adjust working hours, reduce physically demanding tasks, allow for more frequent breaks, organize shift rotations and, where possible, minimize employees’ exposure to the hottest hours of the day.

• Ensure that protective measures are in place: provide sufficient fresh drinking water, arrange for shaded or cool areas when working outdoors, check that the risk assessment document is updated, establish procedures for raising the alarm and provide first aid in the event of heat-related distress.

DON'T

• Wait for an accident to happen before taking action: employers must prevent risks in advance; reacting only after the event runs counter to the duty of prevention incumbent on employers as part of their legal obligation to protect their employees’ health.

• Limit your approach to issuing general guidelines: a simple reminder to employees to be vigilant is not enough; operational measures are required, adapted to the intensity of the heat and the actual work (either outdoor or indoor) performed by employees.

• Overlook potentially vulnerable employees: young people, workers who work alone or in isolation, vulnerable employees, pregnant women and staff exposed to outdoor conditions or working in poorly ventilated premises require special attention and, where necessary, specific arrangements.
