Cold weather brings the risk of frozen pipes in equipment that contains or uses water or that produces condensation. Frozen or damaged fire protection systems can result in extensive property and equipment damage due to burst pipes, or worse, fire losses due to impaired detection systems.

Follow these simple steps to protect vulnerable fire safety equipment. If you have questions or need assistance do not hesitate to contact us.

Fire Sprinkler Systems

  • If your building is equipped with a dry pipe sprinkler system ensure all low points are drained prior to the onset of freezing weather.
  • If your building is equipped with a wet pipe system ensure the temperature in all areas of the building/structure are maintained at or above 40 degrees Fahrenheit.
  • Ensure the antifreeze solution in antifreeze systems is properly mixed to protect against the lowest expected temperature in your region.
  • When conducting a preventive inspection pay particular attention to exposed, often overlooked areas such as attics, garages, closets, etc. Search for isolated drafts or cold air leaks where there are sprinkler pipes.
  • When necessary replace windows or doors and instruct staff to keep them closed tightly.
  • Enclose or insulate pipes containing water that will be exposed to temperatures below 40 degrees Fahrenheit.

Should you experience freeze damage, contact your local fire department and insurance company immediately to determine necessary fire watch procedures until a fire protection contractor can make the necessary repairs. If a burst pipe is causing additional damage locate the isolation valve for that area and shut it off until repairs are made.

An ounce of prevention is worth a pound of cure. If you need assistance preparing for the winter weather we are here to help! Our certified and trained technicians will inspect your facility to identify and remedy areas of vulnerability.

Most dry sprinkler system piping contains trace amounts of water. Our technicians will inspect your piping for proper pitch to identify possible areas of trapped water that may be vulnerable to freezing. Pitch inspection is not included in a standard annual inspection. This is above and beyond the scope of NFPA 25.
