Directives

• 1,3-Butadiene. CPL 02-02-066 [CPL 2-2.66], (October 30, 1997). Establishes policies and provides clarification to ensure uniform enforcement of the Occupational Exposure to 1,3-Butadiene Standard, 29 CFR 1910.1051.

Letters of Interpretation

• OSHA-recognized chemicals as carcinogens or potential carcinogens for Hazard Communication purposes. (October 16, 2003). Tables Z-1, Z-2, and Z-3 are not intended to be lists of chemicals that OSHA recognizes as carcinogens or potential carcinogens for hazard communication purposes. Please be advised that 29 CFR 1910.1200(d)(5)(ii) requires that a mixture "shall be assumed to present a carcinogenic hazard if it contains a component in concentrations of 0.1 percent or greater which is considered to be a carcinogen under (d)(4) of this section".
• Exposure monitoring requirements under the coke oven emissions standard, 29 CFR 1910.1029(e)(1)(iii). (December 7, 1999). Companies must conduct exposure monitoring using the "worst-case" shift or use the representative-sampling procedure specified in the 1,3-butadiene Standard, 29 CFR 1910.1051(d)(1)(iv).
