PCS Code Compliance 2

Question 1

Under OSHA 29 CFR 1926.62, what is the permissible exposure limit (PEL) for airborne lead on construction coating removal projects?

Accepted Answer

50 µg/m³ as an 8-hour TWA

Answer

The OSHA construction lead standard sets the PEL at 50 µg/m³ averaged over an 8-hour workday.

Question 2

A blasting crew's lead exposure monitoring shows 35 µg/m³ (8-hr TWA). Which OSHA threshold has been exceeded?

Accepted Answer

The action level of 30 µg/m³

Answer

35 µg/m³ is above the 30 µg/m³ action level but below the 50 µg/m³ PEL, so action-level requirements such as monitoring and medical surveillance apply.

Question 3

Under 29 CFR 1926.62, a worker must be medically removed from lead exposure when a blood lead level reaches or exceeds what value?

Accepted Answer

50 µg/dL

Answer

The construction lead standard requires medical removal at 50 µg/dL, with return allowed once two tests show levels below 40 µg/dL.

Question 4

Spent abrasive from lead paint removal is tested by TCLP. Above what leachate concentration of lead is the waste classified as hazardous (D008)?

Accepted Answer

5.0 mg/L

Answer

The RCRA toxicity characteristic limit for lead is 5.0 mg/L in TCLP extract.

Question 5

Which OSHA standard requires a written respiratory protection program, fit testing, and medical evaluation for respirator users?

Accepted Answer

29 CFR 1910.134
