Northern Illinois Fire Sprinkler Advisory Board recommends an effective freeze-up prevention program that includes the following elements:
- Conduct a physical inspection of the facility, looking for freeze-up hazards.
- Inspection, and maintenance of the fire sprinkler system includes: identifying if the system contains water that is to be drained before the onset of cold weather. Determine if there are unheated areas in the building containing sprinkler system piping.
- Any freeze prevention program should include annual surveys of buildings and equipment to find insulation and heat tracing deficiencies and to check for unwanted outside air; look for vents and opening in windows, walls, roofs or floors.
- Low point drains (drum drips) on dry-pipe sprinkler systems should be emptied to remove water that may be present from condensation or accidental trips.
- All buildings should provide adequate heating throughout areas susceptible to freezing, such as in stairwells, above dropped ceilings, and attic spaces.
- Monitor boilers and other facility heat supply sources, using personnel and/or supervisory devices.
