PBDE is one of several chemicals that were approved as fire suppressant/resistant additives to replace polychlorinated biphenyls (PCBs) and Polybrominated Biphenyls (PBBs)
Bromine is in the periodic family of chlorine but is “safer” for human contact. Bromine means “food”. Many brominated chemicals are food additives and my favorite food is a naturally occurring bromine...theobromine - god’s food AKA: chocolate.
