CSLB C-33 Painting & DecoratingSafetyMedium
A painting contractor is preparing to use a high-pressure airless spray rig for a large commercial project. Which of the following is the most critical personal protective equipment (PPE) to prevent injection injuries?
- AEye protection with side shields
- BHigh-pressure rated protective clothing
- CRespiratory protection
- DChemical-resistant gloves
Show answer & explanationAnswer & explanation
Correct answer: B. High-pressure rated protective clothing
High-pressure airless sprayers can cause injection injuries if the skin comes into contact with the spray stream. High-pressure rated protective clothing, such as a spray suit, is essential to create a physical barrier against this hazard.
Why the other options are wrong
- A. Eye protection is crucial for general safety but does not protect against skin injection injuries from the high-pressure stream.
- C. Respiratory protection is vital for inhaling paint fumes but does not prevent direct skin injection injuries.
- D. While important for chemical exposure, standard chemical-resistant gloves may not withstand the pressure of an airless spray and prevent injection.
Airless Spray Injection Hazard
Airless paint sprayers operate at extremely high pressures (up to 4000 PSI or more), capable of injecting paint or solvents directly into the skin, causing severe injury.
- Can cause serious injury even from a small, invisible hole in skin.
- Symptoms may be delayed, but immediate medical attention is crucial.
- Requires specific PPE to prevent occurrence.
Memory trick: Pressurized paint can pierce, protect your person first.
