- (a) The responsible employer must ensure that no worker is exposed above the exposure limit prescribed in § 850.22.
(b) The responsible employer must, in addition:
(1) Where exposure levels are at or above the action level, establish a formal exposure reduction and minimization program to reduce exposure levels to below the action level, if practicable. This program must be described in the responsible employer's CBDPP and must include:
- (i) Annual goals for exposure reduction and minimization;
- (ii) A rationale for and a strategy for meeting the goals;
- (iii) Actions that will be taken to achieve the goals; and
- (iv) A means of tracking progress towards meeting the goals or demonstrating that the goals have been met.
- (2) Where exposure levels are below the action level, implement actions for reducing and minimizing exposures, if practicable. The responsible employer must include in the CBDPP a description of the steps to be taken for exposure reduction and minimization and a rationale for those steps.
- (c) The responsible employer must implement exposure reduction and minimization actions using the conventional hierarchy of industrial hygiene controls (i.e., engineering controls, administrative controls, and personal protective equipment in that order).
