Air Sampling

**************************************************************************

NOTE: Air sampling regimen is very dependent on

removal method and applicable laws, edit accordingly.

**************************************************************************

NOTE: Normal practice is to have the Contractor

hire one independent Private Qualified Person (the

PQP) to perform all required functions. However,

some applicable laws forbid this approach and will

dictate when the PQP, the NC or both will be

required to perform the function involved. However,

the Contractor shall always hire a PQP.

**************************************************************************

Sampling of airborne concentrations of asbestos fibers shall be performed

in accordance with 29 CFR 1926.1101 and as specified herein. Sampling

performed in accordance with 29 CFR 1926.1101 shall be performed by the

PQP. [Sampling performed for environmental and quality control reasons

shall be performed by the [PQP] [NC].] Unless otherwise specified, use

NIOSH Method 7400 for sampling and analysis. Monitoring may be duplicated

by the Government at the discretion of the Contracting Officer. If the air

sampling results obtained by the Government differ from those results

obtained by the Contractor, the Government will determine which results

predominate.

3.2.7.1

Sampling Prior to Asbestos Work

Provide area air sampling and establish the baseline one day prior to the

masking and sealing operations for each [demolition] [removal]

[encapsulation] site. Establish the background by performing area sampling

in similar but uncontaminated sites in the building.

required to perform the function involved. However,

the Contractor shall always hire a PQP.

**************************************************************************

NOTE: When an "enclosed" asbestos control area is

not required, retain the appropriate portion in

brackets.
