Risks and prevention — Cement applicator
Shotcrete, stucco, and cementitious coatings expose workers to high concentrations of silica and cement dust. RSST sets strict exposure limits. A P100 respirator is often required in spray zones.
Lance recoil during spraying can cause serious injuries. Operators must receive specific training for the equipment used and have communication with the pump operator. Rebound zones must be barricaded to protect other workers.
Prolonged contact with wet cement causes alkali burns and dermatitis. Waterproof gloves and full-coverage clothing are essential to prevent skin lesions.
