A contractor discovers lead-containing paint on a 1950s building renovation project. The paint chip analysis shows 2.5% lead content. What Cal/OSHA lead standard applies?
Correct Answer
D) General Industry Lead Standard (Section 5198)
Paint containing 0.5% or more lead by weight triggers Cal/OSHA General Industry Lead Standard requirements for renovation work.
Why This Is the Correct Answer
Cal/OSHA General Industry Lead Standard (Title 8, Section 5198) applies to renovation, demolition, and remodeling work involving lead-containing materials when the lead content by weight is 0.5% or greater. At 2.5% lead content, the material far exceeds this threshold. Note that the Construction Lead Standard (Section 1532.1) applies to new construction and certain specific construction activities, while Section 5198 governs renovation/remodeling of existing structures with lead-containing materials.
Why the Other Options Are Wrong
Option A: Construction Lead Standard (Section 1532.1)
Section 1532.1 (Construction Lead Standard) applies primarily to construction activities in new building contexts, not to renovation of existing structures with known lead-containing paint. The distinction between 'construction' and 'general industry/renovation' is a common exam trap β renovation work on existing buildings with lead paint falls under Section 5198.
Option B: Residential Lead Standard only
There is no separate 'Residential Lead Standard' under Cal/OSHA. Residential renovation projects with lead-containing materials are also governed by the General Industry Lead Standard (Section 5198) and additionally by EPA's Renovation, Repair, and Painting (RRP) Rule β but the Cal/OSHA standard that applies is Section 5198, not a residential-specific standard.
Option C: No special requirements - below threshold
2.5% lead by weight is dramatically above the 0.5% threshold that triggers Cal/OSHA lead requirements. Claiming 'no special requirements' would expose workers to serious lead hazards and put the employer in direct violation of Cal/OSHA regulations.
Memory Technique
Remember: '5198 = Renovation/Remodel, 1532.1 = New Construction.' If you're tearing into an old building and find lead paint, you're in 'general industry' territory β Section 5198. If you're doing new construction work where lead is introduced, that's 1532.1.
