Section 6 System Inspection and Maintenance
6.2.2 Annual Maintenance
In addition to the monthly inspection steps and semiannual maintenance the system shall be thoroughly
examined at least once each year.
A minimum of the following steps should be performed during the annual maintenance:
• Surveythehazardtodetermineifithaschangedfromwhatthesystemwasdesignedtoprotect.While
surveying the hazard look for dierent fuels, loss of hazard integrity, new hazards, etc. If discrepancies are
found the changes must be noted and the system re-calculated to determine if the system is appropriate
for the existing hazard.
• oroughlyinspecttheperimeteroftheenclosureforpenetrationsoropeningsthatcouldadversely
aect agent leakage. Any openings found should be noted on the service report and sealed.
• Removeallactuatorsfromcylindervalvesandtestforproperoperation.Leaveallactuatorsountil
service is completed.
Do not install the electric, pneumatic, or manual valve actuators until the system has been fully inspected.
Failure to comply could result in personal injury or death from violent cylinder movement or over-exposure to
high concentrations of agent.
• Examinethecylinderandvalveassemblyforanysignsofdamage,denting,corrosion,etc.asdescribed
in NFPA 2001. If any deciency is identied the cylinder shall be hydrostatically tested.
• Checkthecylinderbracketforcorrosionordamageandmakecertainitissecurelyfastenedtoarigid
vertical structure.
• Checktobecertainthecylinderissecurelyinstalledinthebracketwiththeappropriatefastenersand
that the bracket is at the correct height
• Checkallnozzlestomakecertaintheyaresecurelyinstalledonthepipe,aimedproperly,notcorroded,
not plugged, correct orice size, correct style, and the discharge pattern is not obstructed.
• Checktheconditionofthepipingtomakecertainitisproperlysecuredinthehangersandallttings
are tight.
• Visuallyinspectthepilotactuationhoseforsignsofdamage,corrosion,abrasions,weatherchecking,or
aging. If any deciency is identied the hose shall be replaced or hydrostatically tested.
