Context & protective measures

Background: forest and surface fires occur in Switzerland mainly during dry summers and in Ticino. The main danger to the population is not only the flames but the smoke and fine particles that irritate the airways and severely reduce visibility. The FOEN rates the danger by region on a five-level scale; at high levels, fire bans often apply.

Recommendation

With a high likelihood of occurrence and very high potential impact, consistent caution is required. Use the linked guide to prepare in a targeted way.

What to do now

Do not light any open fire outdoors and strictly observe current fire bans. In case of smoke, close windows and ventilation, stay indoors, and avoid outdoor physical exertion. Keep escape routes clear and an emergency kit packed, and follow evacuation orders from the authorities immediately.
