Answer:
A mask that covers the nose and the mouth can help prevent the inhalation of hazardous materials.
Step-by-step explanation:
"A mask that covers the nose and the mouth can help prevent the inhalation of hazardous materials." references both PPE and protection from "hazardous materials" ie harmful toxins
"First responders have been trained to handle natural hazards." while true does not mention PPE or harmful toxins
"A personal emergency kit should include essential items and be light enough to be carried easily." does not reference harmful toxins and only refers to "emergency kits" not PPE
"Special equipment is often used to detect hazards." while "hazards" could include harmful toxins, it does not reference PPE
Because "A mask that covers the nose and the mouth can help prevent the inhalation of hazardous materials." is the only response which references both PPE and protection from harmful toxins it is the best answer.
