Final answer:
Wet chemical containers and expellant gas assemblies should not be placed near the fire exit to ensure clear evacuation routes during emergencies and to prevent exacerbating fire situations.
Step-by-step explanation:
Wet chemical containers and expellant gas assemblies should not be placed near the fire exit. This is a safety precaution to ensure that evacuation routes remain clear and accessible in the event of an emergency. It is important to follow instructions carefully on how to handle flammable chemicals and to ensure that there are no obstructions to exits. The containers could potentially exacerbate a fire situation if they are located in close proximity to an evacuation path. Moreover, focusing on safe storage, they also should not be placed in areas of the building that do not have adequate ventilation or where people gather, such as dining areas or kitchens, which could lead to inhalation of toxic fumes or accidental fires.
