Notes	These media are prepared by SLTC as needed and are not available for immediate shipment. Please allow time for SLTC to prepare these media prior to sampling.
Special requirements	Submit as a separate sample. If the filter is not overloaded, samples may be collected up to an 8 hour period. After sampling, filter must be transferred to vial with a teflon-lined cap. Sample must be protected from direct sunlight.

^* All sampling instructions above are recommended guidelines for OSHA Compliance Safety and Health Officers (CSHOs), please see the corresponding OSHA method reference for complete details.
