29 C.F.R. § 1960.46 Agency responsibility.
(a) The head of each agency shall establish procedures to assure that no employee is subject to restraint, interference, coercion, discrimination or reprisal for filing a report of an unsafe or unhealthful working condition, or other participation in agency occupational safety and health program activities, or because of the exercise by such employee on behalf of himself or herself or others of any right afforded by section 19 of the Act, Executive Order 12196, or this part. These rights include, among other, the right of an employee to decline to perform his or her assigned task because of a reasonable belief that, under the circumstances the task poses an imminent risk of death or serious bodily harm coupled with a reasonable belief that there is insufficient time to seek effective redress through normal hazard reporting and abatement procedures established in accordance with this part.
(b) Based on the Secretary's evaluation of agencies' procedures for protecting employees from reprisal, the Secretary shall report to the President by September 30, 1982 his findings and recommendations for improvements in procedures for the investigation and resolution of allegations of reprisal.
