Give some examples of the types of hazardous chemicals, specifically oxidizers, stored in homes (such as those stored under counters and sinks, in garages/basements and in pump houses/sheds).
Discuss the following:
A) What problems and dangerous situations can result from the improper storage and use (i.e., mixing them together, etc.) of these chemicals? Describe potential hazardous material interactions.
B) What government agency and statutes/regulation(s) govern for the labeling and registration of these hazardous household products?
