Risks and prevention — Concrete pouring
Concrete pouring exposes workers to chemical contact with cement (alkali burns), pump and vibrator noise, concrete splash, and hazards from handling pump hoses. RSST and CSTC regulations govern protective measures on Québec construction sites.
Appropriate PPE is mandatory: waterproof boots, alkali-resistant gloves, safety goggles, and hearing protection near pumps. Fresh concrete can cause severe dermatitis after prolonged skin contact.
Coordination between the crane operator, pump operator, and ground crew is critical. Signals must be agreed upon before the operation begins. Workers must never position themselves under the concrete pump boom or in the path of a pressurized hose.
