CSLB C-33 Painting & DecoratingSafetyHard
A painting crew is working on a historical building, removing old paint that is confirmed to contain lead. To comply with environmental regulations and protect the public, which of the following containment methods is most appropriate for exterior work?
- AEnclosing the work area with plastic sheeting and negative air pressure
- BWet scraping and collection in open containers
- CPower washing the lead paint into the storm drain system
- DUsing a simple drop cloth below the work area to catch debris
Show answer & explanationAnswer & explanation
Correct answer: A. Enclosing the work area with plastic sheeting and negative air pressure
For exterior lead paint removal, especially on historical buildings, rigorous containment is required. Enclosing the work area with plastic sheeting and maintaining negative air pressure prevents lead dust from escaping into the environment and affecting the public or surrounding areas.
Why the other options are wrong
- B. Wet scraping reduces dust but collection in open containers risks lead dispersion.
- C. Discharging lead paint into storm drains is illegal and highly detrimental to the environment.
- D. A simple drop cloth is insufficient for lead paint containment, as dust can easily become airborne.
Exterior Lead Paint Containment
Methods used to prevent the release of lead-containing dust and debris into the environment during exterior lead paint removal.
- Protects workers, public, and environment.
- Often requires full enclosure and air filtration.
- Regulated by EPA and OSHA.
Memory trick: Lead dust must not leave, so seal and suck it in.
