must provide a National Institute for Occupational Safety and Health NIOSH assigned protection factor APF of at least 10. For purposes of 721.63b, the concentration is set at 1.0%.
A As an alternative to the respirator requirements in paragraph a2i of this section, a manufacturer or processor may choose to follow the new chemical exposure limit NCEL provision listed in the TSCA Order for this substance.
The NCEL is 23.6 mg/m3 3.9 ppm as an 8-hour time weighted average.
Persons who wish to pursue NCELs as an alternative to 721.63 respirator requirements may request to do so under 721.30. Persons whose 721.30
requests to use the NCELs approach are approved by EPA will be required to follow NCELs provisions comparable to those contained in the corresponding TSCA Order.
B Reserved ii Hazard communication.
Requirements as specified in 721.72a through f and g1 and 2. For purposes of 721.72e, the concentration is set at 1.0%. For purposes of 721.72g1, this substance may cause: Internal organ effects; reproductive effects; fatality. For purposes of 721.72g2, when using this substance: Avoid skin contact;
avoid breathing substance; avoid ingestion; use respiratory protection or maintain workplace airborne concentrations at or below an 8-hour time-weighted average of 23.6 mg/m3
3.9 ppm; use skin protection.
Alternative hazard and warning statements that meet the criteria of the Globally Harmonized System and OSHA
Hazard Communication Standard may be used.
iii Industrial, commercial, and consumer activities. Requirements as specified in 721.80f, k, and o. For purposes of 721.80k, the use is as a refrigerant used in closed systems for chillers commercial comfort air conditioners and industrial process refrigeration.
b Specific requirements. The provisions of subpart A of this part apply to this section except as modified by this paragraph b.
1 Recordkeeping. Recordkeeping requirements as specified in 721.125a through i are applicable to manufacturers and processors of this substance.
