(i) Protection in the workplace. Requirements as specified in § 721.63(a)(1), (2)(i), (iii) and (iv), (3) through (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)(1) 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 § 721.63(a)(5), respirators must provide a National Institute for Occupational Safety and Health assigned protection factor of at least 1000).

(ii) Hazard communication.

It is a significant new use to import the substance if the average molecular weight is less than or equal to 1,390 Daltons, more than 11% is less than 500 Daltons, or more than 30% is less than 1,000 Daltons. It is a significant new use to use the substance other than as an ultraviolet curable resin.
