Respiratory protection on offshore drilling rigs.
Appl Occup Environ Hyg 1999 Mar; 14(3):141-148
The National Institute for Occupational Safety and Health (NIOSH) received a request for technical assistance from the Department of the Interior, Mineral Management Services (MMS) concerning respiratory protection against hydrogen sulfide (H2S) on offshore drilling rigs. Specific concerns were with the general use of hooded escape self-contained breathing apparatus (ESCBAs) and with the adequacy of the air capsule (coil reserve) five-minute, hooded, continuous-flow, ESCBA based on several deficiencies identified by MMS, including low air flow rate, leaks, no airline hookup, and a service life of five minutes or less (due to leaks). NIOSH investigators conducted a site visit on an offshore drilling rig located on the outer continental shelf of the Pacific Ocean approximately six miles off the coast of Santa Maria, California. It is designed to support both drilling and production operations. At the time of the NIOSH site visit, the platform was in the production phase and housed 15 workers.
