Question 3579 Deck General

The correct answer is D) facial respirator mask. When loading or discharging dry materials like mud or cement, crew members should use a facial respirator mask to protect themselves from inhaling the fine particulates. This is in accordance with safety regulations to minimize exposure to airborne hazards. The other options, while potentially useful in other situations, are not the appropriate personal protective equipment (PPE) for this specific task. Goggles alone do not provide sufficient respiratory protection, while ear plugs and a fireman's outfit are not the primary safety gear needed for this operation.
