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

Likelihood is rated medium and potential impact high. Use the linked guide on protection during wildfires to prepare.

What to do now

Strictly observe current fire bans, do not light open fires outdoors, and close windows and ventilation if smoke is present. Prepare escape routes and an emergency kit, and follow authorities' instructions immediately.
