A renovation project involves disturbing 120 square feet of paint in a building built in 1968. What Cal/OSHA lead regulation applies?
Correct Answer
A) Section 1532.1 construction lead standard applies
Cal/OSHA Section 1532.1 construction lead standard applies to any construction activity that may result in employee exposure to lead, regardless of square footage, in pre-1978 buildings.
Why This Is the Correct Answer
Cal/OSHA Section 1532.1 is the construction industry lead standard and applies to any construction, demolition, renovation, or repair work that may expose employees to lead — regardless of the square footage disturbed. Because this is a construction activity in a pre-1978 building (which presumptively contains lead-based paint), 1532.1 governs worker protection requirements including exposure assessment, protective equipment, and hygiene practices.
Why the Other Options Are Wrong
Option B: Section 5198 general industry lead standard applies
Section 5198 is the Cal/OSHA lead standard for general industry (manufacturing, battery plants, etc.), not construction. Construction activities are always governed by Section 1532.1, even if the work is light renovation.
Option C: No special requirements since it's under 500 square feet
There is no square footage threshold under Cal/OSHA that exempts construction workers from lead protection requirements. The EPA RRP program has a 6 sq ft interior / 20 sq ft exterior threshold for renovator certification, but Cal/OSHA 1532.1 has no such exemption — any disturbance triggers its application.
Option D: Only EPA RRP rules apply, not Cal/OSHA
EPA RRP rules protect building occupants (especially children and pregnant women) through lead-safe work practices, while Cal/OSHA 1532.1 protects workers from occupational lead exposure. Both can apply simultaneously — EPA RRP does not replace Cal/OSHA requirements.
Memory Technique
1532.1 = Construction Lead. Think '1-5-3-2 = 1 simple rule: construction disturbs lead, workers need protection.' The '1' at the end of 1532.1 means it's the #1 construction lead standard.
