this section for the significant new uses described in paragraph a2 of this section.
2 The significant new uses are:
i Protection in the workplace.
Requirements as specified in 721.63a2i and a3 through 5.
When determining which persons are reasonably likely to be exposed as required for 721.63a1 and 4, engineering control measures e.g., enclosure or confinement of the operation, general and local ventilation or administrative control measures e.g., workplace policies and procedures shall be considered and implemented to prevent exposure, where feasible. For purposes of 721.63a5, respirators must provide a National Institute for Occupational Safety and Health NIOSH assigned protection factor APF of at least 50, or at least 1000 if the substance is spray-applied.
ii Industrial, commercial, and consumer activities. It is a significant new use to manufacture including import the PMN substance with a triethylamine concentration greater than the confidential concentration stated in the PMN.
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 e and i are applicable to manufacturers and processors of this substance.
