Notes

The sampling parameters and method listed above were developed for STYRENE (VINYL BENZENE; PHENYLETHYLENE) but are appropriate to use for sampling VINYL TOLUENE as well. To sample for α-methylstyrene or β-methylstyrene as described in NIOSH method 1501, follow the sampling guidance described in that method.

Special requirements

* 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.
