Lead

1.2.11

Lead

Metallic lead, inorganic lead compounds, and organic lead soaps.

1.2.12

Lead-Based Paint (LBP)

Paint or other surface coating that contains lead in excess of 1.0

milligrams per centimeter squared or 0.5 percent by weight.

1.2.13

Lead-Based Paint Activities

In the case of target housing or child occupied facilities, lead-based

paint activities include; a lead-based paint inspection, a risk assessment,

or abatement of lead-based paint hazards.

1.2.14

Lead-Based Paint Hazard (LBP Hazard)

Any condition that causes exposure to lead from lead-contaminated dust,

lead-contaminated soil, lead-based paint that is deteriorated or present in

accessible surfaces, friction surfaces, or impact surfaces that would

result in adverse human health effects.

1.2.15

Paint with Lead (PWL)

Any paint that contains lead as determined by the testing laboratory using

a valid test method. The requirements of this section does not apply if no

detectable levels of lead are found using a quantitative method for

analyzing paint using laboratory instruments with specified limits of

detection (usually 0.01%). An X-Ray Fluorescence (XRF) instrument is not

considered a valid test method.

1.2.16

Lead Control Area

A system [of control methods] to prevent the spread of lead dust, paint

chips or debris to adjacent areas that may include temporary containment,

floor or ground cover protection, physical boundaries, and warning signs to

prevent unauthorized entry of personnel. HEPA filtered local exhaust

equipment may be used as engineering controls to further reduce personnel

exposures or building/outdoor environmental contamination.

1.2.17

Lead Permissible Exposure Limit (PEL)

Fifty micrograms per cubic meter of air as an 8 hour time weighted average

as determined by 29 CFR 1926.62. If an employee is exposed for more than

eight hours in a workday, the PEL shall be determined by the following

formula:

PEL (micrograms/cubic meter of air) = 400/No. hrs worked per day

1.2.18

Personal Sampling

Sampling of airborne lead concentrations within the breathing zone of an

employee to determine the 8 hour time weighted average concentration in

accordance with 29 CFR 1926.62. Samples shall be representative of the

employees' work tasks. Breathing zone shall be considered an area within a

hemisphere, forward of the shoulders, with a radius of 150 to 225 mm 6 to 9

inches and centered at the nose or mouth of an employee.
