Title Noise on offshore platforms.
Bibliographic information Nov. 1978, Vol.30, No.11, p.524-527. Illus. 4 ref.
Abstract Offshore platform workers are exposed to very high noise levels (12-h shift, 2 weeks on, 2 weeks off). Noise exposure continues in off-duty periods, due to the close proximity of leisure and working areas. The 1976 Health and Safety Executive Code of Practice recommends a maximum level of 90 dB(A) for daily 8h exposure to non-fluctuating noise. For other levels and exposure times an equivalent sound level (Leq) can be calculated and compared with the 90dB(A) standard. As the offshore worker is exposed to high noise levels for the full 12h of his working day, the 90 dB(A) 8h standard can be reduced to 88dB(A) on the basis of the Leq calculation. Considerations on hearing damage, speech interference and accident hazard from misunderstood verbal communications, hearing conservation, major noise sources on oil rigs (gas turbine and diesel generators, pumps and compressors, and air dryers, etc.).
