Final answer:
The correct answer is option C. Preincident plans.
Step-by-step explanation:
The phrase PPE stands for Personal Protective Equipment, which is crucial in ensuring the safety of individuals working in potentially hazardous conditions. PPE can be determined by several resources. Notably, preincident plans typically include an inventory of necessary PPE that would be required for workers in anticipation of certain kinds of incidents.
Moreover, the ERG (Emergency Response Guidebook) can provide guidance on the types of PPE needed for specific hazardous materials incidents. Shipping papers can offer details about the contents being shipped, thereby indicating the PPE necessary for handling those materials safely. Lastly, incident action plans devised during an emergency response will outline the PPE required by responding personnel based on the specifics of the current situation.
