OSHA 10-Hour Construction ReviewHealth Hazards in ConstructionMedium
A construction worker is planning to work in an area where lead-based paint is suspected, but no previous testing has been done. According to OSHA, what is the initial action the employer must take regarding worker protection?
- ABegin work and monitor workers for symptoms of lead exposure.
- BProvide N95 respirators to all workers in the area.
- CAssume the paint is lead-based and implement full lead-exposure controls.
- DConduct air monitoring to determine airborne lead levels before work begins.
Show answer & explanationAnswer & explanation
Correct answer: C. Assume the paint is lead-based and implement full lead-exposure controls.
OSHA's Lead in Construction standard requires employers to presume lead-based paint exists in structures built before 1978 unless testing proves otherwise. This presumption triggers the need for full lead-exposure controls.
Why the other options are wrong
- A. Monitoring for symptoms is reactive and does not meet the proactive requirements for lead protection.
- B. Respirators are part of controls, but the initial action is the presumption and implementation of comprehensive controls.
- D. Air monitoring is done after controls are in place or to confirm exposure levels, not as the initial action when lead is presumed.
Lead-Based Paint Presumption (Construction)
For construction work, OSHA requires employers to presume that paint or surface coatings in buildings built before 1978 contain lead, unless the employer determines through analysis that lead is not present.
- Applies to buildings built before 1978.
- Employer must presume lead is present unless tested otherwise.
- Triggers implementation of lead-specific protective measures.
Memory trick: Before '78, Assume and Protect!
