![]() Knowledge of sampling procedures, including sampling media, recommended air volumes, and sample storage precautions, are essential in planning proper sampling strategies.īulk samples are sometimes necessary to support analyses of air samples, to document the source of air contaminants or to identify additional hazards. Screening techniques and devices, such as detector tubes and direct-reading meters, may provide valuable information when their use and their detection limits are appropriate (see Section II: Chapter 3 Technical Equipment: On-Site Measurements). Sampling strategies should be planned for a meaningful evaluation of air contaminants and prudent use of limited resources. The SLTC is aware that unique sampling situations will arise during some inspections and it is essential that OSHA Compliance Safety and Health Officers (CSHOs) contact, and work closely with, the SLTC whenever questions arise. The use of sampling methods not approved by the SLTC may require resampling with an approved sampling procedure. Only procedures approved by the SLTC should be used. Sometimes the Salt Lake Technical Center (SLTC) will approve the use of procedures developed by other organizations. Sampling and analytical methods that have been validated by either OSHA or the National Institute for Occupational Safety and Health (NIOSH) should be used whenever possible. Other reference resources are OSHA's Chemical Sampling Information (CSI) file and the OSHA Field Operations Manual (FOM). This chapter provides basic information related to sampling air contaminants.
