DOE-EM-STD-5503-94
8.0. EXPOSURE MONITORING/AIR SAMPLING
8.1. BACKGROUND
Hazardous waste activities generate the potential for employee exposure to, and/or off-site
migration of, hazardous concentrations of airborne substances. This section provides the general
HASP guidance for the exposure monitoring/air sampling program and specific activities that
should take place during hazardous waste activities.
The overall objectives of the exposure monitoring/air sampling section are:
Describe the overall exposure monitoring and air sampling program by providing general
information about the purpose of the exposure monitoring and air sampling program,
regulatory requirements, and guidance documents; and
Identify the different components of the exposure monitoring/air sampling program,
including personnel qualifications, air contaminants, instrumentation, worker exposure,
level of protection, and offsite, perimeter, and meteorological monitoring, quality
assurance/quality control, and recordkeeping.
The objectives of exposure monitoring/air sampling are to accurately determine:
Exposure levels for site workers,
Work areas generating the most significant airborne contaminants,
Whether migration is occurring, and
Whether modified levels of protection or engineering controls are required.
This section of the HASP should be prepared in accordance with guidelines contained in the EPA
Standard Operating Safety Guides, June 1992; EPA, Office of Emergency and Remedial
Response, Air Surveillance for Hazardous Materials; and the NIOSH Manual of Analytical
Methods (latest edition).
8.2. GENERAL GUIDANCE
An exposure monitoring/air sampling program should be prepared and implemented to identify
and quantify airborne levels of potentially hazardous substances. Appropriate direct-reading
(i.e., real time) air monitoring and time-integrated (e.g., 8 hour time-weighted average, 15 minute
short term exposure limit) air sampling should be conducted in accordance with applicable
regulations (e.g., OSHA, EPA, State, NRC). Both direct-reading and time-integrated sampling
should be used to test for the presence of air contaminants. Compounds which are found by
time-integrated sampling, but are not detected by direct reading air monitors, may warrant
modification of both the monitoring program and the levels of protection.
