(i) Protection in the workplace. Requirements as specified in § 721.63(a)(4), (5) (respirators must provide a National Institute for Occupational Safety and Health assigned protection factor of at least 50) and (6) (particulate), (b) (concentration set at 0.1%), and (c). When determining which persons are reasonably likely to be exposed as required for § 721.63(a)(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.

(ii) Hazard communication. Requirements as specified in § 721.72(a) through (e) (concentration set at 0.1%), (f), (g)(1)(ii) through (ix), (2)(i) through (v), and (5).

It is a significant new use to manufacture the substances at facilities other than those equipped with pollution controls, such as a bag house, that remove particulates from the air at 99% or greater efficiency. It is a significant new use to process the substances other than in an enclosed system that does not allow for the release of particulates or at facilities equipped with pollution controls, such as a bag house, that remove particulates from the air at 99% or greater efficiency.
