Utility Systems
• Electrical systems
• Heating, ventilation and air conditioning (HVAC) systems
• Fuel supply/storage systems
• Water systems
• Sewer systems
![Page 9: 2009 Annual Conference September 22, 2009 Tom Skebey, CFM](https://reader036.vdocuments.us/reader036/viewer/2022062309/56649dbf5503460f94ab2771/html5/thumbnails/9.jpg)
Electrical Systems
Protective measures:• Raise or relocate equipment
and devices above the FPL• Seal outside wall penetrations,
mechanically protect wiring system in flood-prone locations
• Seal out moisture• Add Ground Fault Interrupting
Circuit (GFIC) breakers

Heating, Ventilating, and Air Conditioning (HVAC) Systems
• Maintenance of required equipment clearances and access dictated by code and/or manufacturer
• Provision of adequate combustion air for fuel-burning equipment
• Modification and/or maintenance of proper venting of fuel-burning equipment
• Eliminating ductwork below the DFE
![Page 11: 2009 Annual Conference September 22, 2009 Tom Skebey, CFM](https://reader036.vdocuments.us/reader036/viewer/2022062309/56649dbf5503460f94ab2771/html5/thumbnails/11.jpg)
Fuel Supply/Storage Systems
• Use of flexible connections
• Adequate support and anchorage to resist hydrostatic and hydrodynamic forces that act on tank
• Relocation of fuel tank because of equipment relocation
• Use of automatic cut-off valves
