Lessons Learned - GOX Vent Arm Air Receivers Bleed Manifold Venting Operations
Year: 1992
Abstract: Description of Driving Event:
During bleed down of the 125 psi air system, a process which lasts less than one minute, the noise level at the Pad B gaseous oxygen (GOX) vent arm air receiver outlet vent exceeds permissible OSHA noise exposure limits. A noise hazard survey conducted during the bleed down operation was performed on the air system to determine the noise level near the operator's ear. This survey recorded a noise level of 126.5 DBA. OSHA 1910.95, occupational noise exposure, limits noise exposure for fifteen minutes or less to 115 DBA. A possibility exists for personnel permanent hearing loss.
