C33 Regulations and Procedures for Lead-Based Paint Abatement 5

Question 1

When encapsulation is chosen as a lead hazard control method in California, what is a required condition for it to be approved?

Accepted Answer

The substrate must be stable and the encapsulant must be listed on the EPA's acceptable products list

Answer

Encapsulation is only acceptable when the underlying substrate is stable and the product used is an EPA-recognized encapsulant; deteriorating substrates require abatement.

Question 2

Which agency enforces the California lead RRP regulations for renovation work in child-occupied facilities?

Accepted Answer

California Department of Public Health (CDPH)

Answer

CDPH is the primary state agency that enforces California's lead-safe renovation, repair, and painting rules in child-occupied facilities and pre-1978 housing.

Question 3

What is the California-defined action level for lead in air during abatement that triggers mandatory engineering controls?

Accepted Answer

30 µg/m³ as an 8-hour TWA

Answer

Cal/OSHA's lead standard sets an action level of 30 µg/m³ as an 8-hour time-weighted average, which triggers required medical surveillance and additional controls.

Question 4

During lead abatement in an occupied multi-family building, what must be done before residents can return to the work area?

Accepted Answer

Clearance examination including visual inspection and wipe sampling by a certified independent inspector

Answer

Residents cannot return until a certified, independent inspector performs a clearance examination that includes both a visual inspection and dust wipe samples meeting established clearance standards.

Question 5

A C-33 contractor is using chemical strippers to remove lead paint from interior trim. What is the primary regulatory concern unique to this method?

Accepted Answer

Volatile organic compound (VOC) emissions from the stripper

Answer

Chemical strippers used indoors generate VOC emissions subject to California Air Resources Board and local air district regulations, requiring proper ventilation and compliant product selection.
