ASBESTOS AIR MONITORING REQUREMENTS SECTION 01 45 23

SECTION 01 45 23: ASBESTOS AIR MONITORING REQUIREMENTS

PART 1 GENERAL

1.1. AIR MONITORING BY CONTRACTOR

A. An Independent Testing Laboratory shall be retained by the Contractor. All air-monitoring analysis shall be performed by an Industrial Hygienist. The Hygienist must be experienced and trained in asbestos sampling and analysis. At a minimum, documentation of prior asbestos sampling and analysis experience, plus satisfactory completion of the NIOSH 582 course or equivalent formal asbestos education, will be required. The laboratory must meet the requirements specified in Section 02 82 13. Air sample collection may be performed by an Industrial Hygienist or the Contractor's foreman at the Contractor's option.

B. Documentation shall be kept for each filter sample procured as to worker sampled, work area location, date and time taken, volume of air drawn through filter, pump identification number and calibration. Documentation shall indicate in what areas tests were taken and shall clearly indicate the specified maximum allowable fiber levels for each area tested.

Report all data on copies of "Asbestos Air Sampling Data Form" bound in these

Specifications or similar form. Fill in all information on every form. Submit chain-of-custody records along with all samples.

C. The samples shall be collected on 25 mm filters and analyzed within 12 hours using the membrane filter method at 400-500x magnification with phase contrast illumination - NIOSH

Analytical Method No. 7400 - for laboratory and field analysis. The analyst shall sign and submit permanent records of all samples analyzed directly to the Environmental Consultant.

The Independent Testing Laboratory shall seal the unused portion of all filters in airtight containers so that individual samples can be reanalyzed at a later date if necessary. The containers shall be clearly labeled with Project Name and Sample Number and shall become property of the Owner at work completion at the Owner's request.

D. The Contractor's testing laboratory shall submit sample analysis results to the Environmental

Consultant verbally within 18 hours from the time of collection and written within two weeks including chain-of-custody and equipment calibration records.

E. Contractor's Sampling During Abatement:

1. Air monitoring shall be performed to provide samples during the period of asbestos abatement in each work area. Begin sampling when asbestos removal commences.

Samples are to be taken where Class I or II work is being conducted during each 8-hour work shift until abatement is complete in that work area or until a negative exposure assessment is established per 29 CFR 1926.1101.

2. The Contractor shall determine which worker(s) in each work area is probably experiencing the most severe exposure. This is the "Most Contaminated Worker(s)". 8-hour TWA and 30-minute excursion samples shall be collected on this worker(s). This worker shall wear a personal sampling pump and the sample shall be drawn from the breathing zone of this worker. All other samples are area samples.

3. The number of air samples collected shall be determined by the Contractor, and may be altered during the project based on work activity and results.

4. The maximum allowable fiber levels shall be as determined by the Environmental

Consultant based on the respiratory protection being utilized.

F. Contractor shall notify the Department of Environmental Quality of air monitoring clearance results as supplied by Environmental Consultant. Notification shall be within 30 days after monitoring procedures were performed in accordance to OAR 340-32-465.

1.2. AIR MONITORING BY OWNER

A. The Owner has retained an experienced Industrial Hygienist/Environmental Consultant to collect and analyze asbestos air samples. Documentation of sample results will be forwarded to the Contractor as appropriate to regulatory requirements.

B. Samples analyzed by phase contrast microscopy will use NIOSH Analytical Method No. 7400.

Samples analyzed by transmission electron microscopy will use either the AHERA methodology, 40 CFR Part 763, or Yamate Level Two.

C. Owner's Air Sampling During and After Abatement:

1. Air Sampling Table is to be used as a guide. The Owner's Industrial

Hygienist/Environmental Consultant may modify criteria. Modifications to the

Maximum Allowable Fiber Count shall be made in writing by the Owner.
