🔍 Key Concepts

• Personal protective equipment (PPE) required when working in dusty atmospheres • Health risks of cement and dry mud dust to eyes, lungs, and skin • Which body parts are already protected by a facial respirator mask and which still need additional protection

💭 Think About

• Think about what additional hazard exists from airborne dry cement or mud besides breathing it in. • Which part of the body is most at risk from fine dust particles that can blow around in the air during loading and discharging? • Compare each option and ask: which one directly reduces injury from dust exposure, not from fire, noise, or slipping?

✅ Before You Answer

• Verify which PPE is typically paired with respirators in dusty cargo operations. • Eliminate options that protect against unrelated hazards like heat, flame, or noise rather than dust. • Focus on equipment that protects sensitive tissues exposed to drifting dust, especially in windy conditions.
