Standard Interpretations - Table of Contents |
Standard Number: | 1910.95; 1910 Subpart Z |
November 10, 9999
The purpose of this memorandum is to resolve issues concerning adjustments of the PEL during extended work shifts. This applies for exposures to the noise levels of Table G-16 of 29 CFR 1910.95 or substances found in Subpart Z. Current OSHA policy requires only the action level to be reduced for exposures to noise during extended work shifts; the PEL is not required to be adjusted. The only standards which require PEL adjustments are the lead standards in construction and general industry. These standards have a specific provision which requires work shift adjustments. Existing policy for Occupational Exposure to Cotton Dust also has a requirement to adjust extended work shifts when employees are required to wear respirators for a portion of the work shift to reduce their level of exposure, as set forth in the Federal Register, Vol. 45, No. 251, pp. 85736-85739. The contribution that the extended work hours adds to employee exposure must be included in calculating the required time respirators must be worn during the shift. As stated in a previous memorandum dated November 8, 1996: Compliance officers can choose one of two approaches for employees who work extended work shifts beyond 8 hours. The choice taken will depend on the nature of the hazardous chemical.
