A painting supervisor observes a worker using a power washer to clean a building exterior. The worker is wearing safety glasses but no face shield. What is the MOST immediate and significant eye/face hazard associated with power washing that necessitates additional protection?
- ASplashback of cleaning chemicals and debris.
- BFatigue from prolonged vibration of the equipment.
- CExposure to UV radiation from sunlight reflection.
- DWind-borne dust from nearby construction.
Show answer & explanationAnswer & explanation
Correct answer: A. Splashback of cleaning chemicals and debris.
The high pressure of a power washer can cause significant splashback of water, cleaning chemicals, and dislodged debris, posing an immediate and severe risk of eye and face injuries. Safety glasses alone are insufficient for this hazard.
Why the other options are wrong
- B. Fatigue is a general ergonomic concern, not an immediate eye/face hazard.
- C. UV radiation is a long-term hazard, not an immediate and significant impact risk from power washing.
- D. Wind-borne dust is a general environmental factor, but splashback from the power washer itself is more direct and severe.
Power Washing Eye/Face Protection
Power washing presents significant splashback hazards from water, chemicals, and debris, requiring both safety glasses and a face shield for adequate eye and face protection.
- High-pressure spray can cause severe eye injuries.
- Cleaning chemicals can cause burns or irritation.
- Dislodged paint chips or dirt can cause impact injuries.
