Hazards5.1 Safety HazardsThe following safety precautions mustbe taken when conducting tests in accordance with testprocedures that conform with this test method. However, th

32、is isnot an inclusive listing of all hazards which may occur whenthis test method is followed, see 1.5. Appropriate safety hazardstatements must be included in test procedures that conformwith this test method.5.1.1 Live control circuits are exercised during tests per-formed in accordance with this

33、test method. This can result inthe inadvertent discharge of seawater or seawater/foam solu-tion.5.1.1.1 Remote operation of valves which allow dischargeof fluids directly into interior spaces of the vessel is required.5.1.1.2 Tag out electrical circuits or tag closed valves asappropriate for each te

34、st.5.1.2 The fixed foam firefighting system includes reliefvalves and pressure-regulating valves which limit the internalpressures to which piping and valves of the system aresubjected. Failure of these devices to control or limit systempressure may result in component failures.5.1.3 The following s

35、afety and control devices are requiredto conduct the tests:5.1.3.1 Pumps relief valves;5.1.3.2 Seawater sprinkling pump discharge bypass-overboard relief valves which must be set in accordance withthe maximum system operating pressure; and5.1.3.3 Zone sprinkling control, remotely operated valves,as

36、applicable.5.1.4 All precautions to ensure safety of life and equipmentprotection in compliance with the industrial facilitys andvessels established safety precautions shall be followed at alltimes in the conduct of foam firefighting system tests.5.1.5 Portions of the fixed foam firefighting system

37、shouldnot be disabled or isolated for tests until just before the aspecific test event is scheduled to commence. This will leavethe system functional for use in case of an actual fire.5.2 Precautionary StatementsThe following precautionsshould be taken when conducting tests in accordance with testpr

38、ocedures which conform with this test method. Appropriateprecautions and warning statements must be included in testprocedures that conform with this test method.5.2.1 All appropriate electrical circuits must be de-energized and tagged when doing any test or demonstrationinvolving contact with elect

39、rical conductors.5.2.2 It is against environmental regulations to dischargeseawater/foam solutions within 3 miles of shore in the UnitedStates. Care must be taken to prevent discharge of foam intocoastal waters of any country. Therefore, all in-port testing is tobe accomplished using fresh water or

40、clean seawater. Foamconcentration testing, by dispersion of actual seawater/foamsolution, is to be accomplished only when underway, welloutside coastal waters, or the seawater/foam solution is dis-charged to a containment vessel for disposal in conformancewith local regulations.5.2.3 Sprinkling or o

41、ther discharge into interior spaces canlead to water or seawater/foam solution accumulation. Vesselstability can be dangerously affected if dewatering systems arenot fully functional and operating. Operators must closelymonitor the amount of water accumulated on deck during anyphase of demonstration

42、s or testing. Demonstrations or testingshould be suspended if such accumulation cannot be controlledand sufficient stability maintained.5.2.4 All equipment or surfaces that could be damaged bywater during testing, in way of hose reel discharge areas or inzones where fresh water or seawater/foam solu

43、tions will bedischarged from foam maker sprinkling nozzles, or both,should be covered with plastic or otherwise protected from thedischarge.5.2.5 Any piping flanges that formerly were blanked toconduct hydrostatic testing of the foam distribution systemshould be inspected for tightness during the op

44、erational tests.5.2.6 Precaution shall be taken to ensure proper valvealignment to prevent flooding the vessel during any testrequiring operation of the seawater sprinkling system, seawatersprinkling pumps, foam proportioning pumps, and foam con-centrate transfer pumps.5.2.7 Any tests requiring seaw

45、ater or seawater/foam solu-tion to be pumped through foam distribution system pipingshall be conducted only after precautions have been taken toinsure the watertight integrity at the maximum system operat-ing pressure of all affected piping and valves.5.2.8 Appropriate zone control valves shall be t

46、agged closedduring in-port testing to preclude accidental discharge of foamconcentrate entering the distributive system or being dis-charged overboard.5.2.9 Isolate system areas or zones that are not used in aspecific test.5.3 Remedial StatementsSystem restoration followingdemonstrations should incl

47、ude the following actions.5.3.1 Restore all electrical power to the pumps and controls.Ensure that all electrical and control circuits are set for normaloperation.5.3.2 Ensure that tags installed on remotely operated valveshave been removed.5.3.3 Ensure that all distribution piping and valves areali

48、gned for normal operation.5.3.4 Clean up all areas and equipment that may have beenwetted by sprinkling or flooding incidental to these demonstra-tions.5.3.5 Remove any “socks” or other devices installed tocontain water or foam discharged during demonstrations.5.3.6 Remove any test instrumentation o

49、r gauges installedfor the demonstrations.5.3.7 Ensure that foam concentrate tanks are filled withfoam concentrate.6. Overview of Fixed Foam Firefighting System Tests6.1 There are two phases of testing the fixed foam andseawater sprinkling system: system installation tests and sys-tem operational tests.6.2 Installation testing is intended to demonstrate the integ-rity of the system as it was installed in the vessel. It comprisesa series of tests to demonstrate that the foam/sprinkling systemis completely installed. It is essential that this testing becompleted before
