Seacoast Chief Fire Officers Mutual Aid District
The NH State Fire Marshal's Office (NHFMO) would like to remind everyone that “microwaving their masks to kill germs” is a fire hazard and an extremely bad idea. Cloth masks can overheat quickly and catch fire. Disposable masks also have a metal nose wire and can cause sparks, a fire, and/or break your microwave.
The CDC recommends properly sterilizing masks with detergent in the washing mashine.
