Response: U.S. COAST GUARD LTR: THE COAST GUARD CONCURS WITH THIS RECOMMENDATION. REVIEW OF PORTABLE TANK CLEANING EQUIPMENT HAS REVEALED THAT TANK CLEANING HOSES AND PORTABLE ELECTRIC BLOWERS, WHEN DEFECTIVE, CAN PRESENT HAZARDS DURING TANK CLEANING. A TANK CLEANING MACHINE INTRODUCED INTO A CARGO TANK MUST BE PROPERLY GROUNDED, AS FAILURE TO DO SO COULD RESULT IN THE ACCUMMULATION OF AN ELECTROSTATIC CHARGE ON THE MACHINE. THIS CHARGE COULD EVENTUALLY DISCHARGE WHEN THE MACHINE IS PLACED IN CLOSE PROXIMITY TO THE CARGO TANK SURFACE. IN ORDER TO MAINTAIN ELECTRICAL CONTINUITY, A BRAIDED WIRE IS ENCASED IN THE HOSE MATERIAL, AND TO INSURE MAINTENANCE OF ELECTRICAL CONTINUITY, PERIODIC TESTS SHOULD BE PERFORMED IN ACCORDANCE WITH IOTTSG PROCEDURES. THE USE OF PORTABLE ELECTRIC BLOWERS HAS RESULTED IN SOME GAS FREEING MISHAPS. HOWEVER, THE COAST GUARD DID NOT FIND PORTABLE ELECTRIC BLOWERS TO BE IN WIDESPREAD USAGE THROUGHOUT THE TANKER INDUSTRY. NOTWITHSTANDING, IF THEY ARE USED, THEY SHOULD BE PERIODICALLY TESTED TO INSURE THAT THEY ARE BEING MAINTAINED IN AN EXPLOSION PROOF CONDITION. THE COAST GUARD IS OF THE OPINION THAT TANK CLEANING HOSES SHOULD BE TESTED FOR ELECTRICAL CONTINUITY AND PORTABLE ELECTRIC BLOWERS VISUALLY EXAMINED DURING THE COURSE OF ROUTINE U.S. COAST GUARD INSPECTIONS. THE PROCEDURES TO BE FOLLOWED FOR THE ABOVE NOTED TEST AND INSPECTIONS WILL BE PROMULGATED EITHER THROUGH AN NVC OR IN THE APPROPRIATE SECTION OF THE MARINE SAFETY MANUAL.
