Avoid using surge protectors in plastic housings. Metal housings will impede MOV fires better.
Do not place MOV products on carpeting, near curtains or by other flammable surfaces.
Shake the protector periodically and listen for loose parts. Discard if it rattles.
If the housing has burn marks (soot, discoloration), discard immediately.

If a product claims to have safety certification, the product label or manufacturer’s web site will have the information posted. You should be able to verify certifications on the testing laboratory’s web site using the manufacturer’s file number.
