Inspection of BioMarine Bio Pak 60P Closed Circuit SCBA (TC-13F-85) at the Madison, Ohio Fire Department, 45 pages.
NIOSH 1981 Feb:0 pages
The personal respirators used by the Madison Ohio Fire Department (SIC-9224) were evaluated. The study was requested by the fire department after one respirator had apparently failed during use. The study was performed jointly by NIOSH and BioMarine on January 12, 1981. The 12 BioMarine Bio Pak 60P SCBA respirators were found to be in good general maintenance. Two were not in the NIOSH approved configuration; these contained an 11 inch diaphragm compression spring rather than the 9 inch springs NIOSH recommended. Madison had received the retrofit springs but had not installed them. This problem was not the cause of the catastrophic failure. None of the units exhibited malfunctions which could explain the cause of the unit failure. The authors recommend that BioMarine institute an incoming quality control specification for pressure relief rupture disc retaining screw torque on cylinder valve assemblies. Madison should provide periodic instruction to firefighters on the proper use and care of the respirators. Routine periodic maintenance should be performed on all units by qualified technicians.
