Final answer:
Shipping papers or packages labeled with "INHALATION HAZARD" must be handled according to the United States Department of Transportation hazardous materials regulations ensuring the safety of individuals and the environment.
Step-by-step explanation:
When the words "INHALATION HAZARD" appear on shipping papers or on the package, the United States Department of Transportation hazardous materials regulations require specific handling and transportation procedures to be followed. These regulations are in place to protect individuals and the environment from the potential dangers posed by the inhalation of hazardous materials. The materials must be packaged properly, and anyone handling or transporting these materials must be properly trained to deal with hazardous substances. Furthermore, the Environmental Protection Agency's (EPA) hazardous waste regulations might also apply, ensuring the safe disposal of hazardous materials, thereby preventing environmental contamination and exposure risks to humans.
Additionally, in a lab setting, the label indicating an inhalation hazard would require appropriate measures such as using fume hoods to prevent fume inhalation and following strict safety procedures for handling, as outlined by the instructor.
