Your group has been given the identity of a chemical. Your task is to design a decontamination line to properly decontaminate workers. Research your chemical in the NIOSH Pocket Guide and, as a group, decide what level of protection the workers in the Hot Zone (Exclusion Zone) and all areas of the decon line will be wearing. Another consideration is what materials will be used in the decon line.
