NFPA issues safety alert regarding antifreeze in residential sprinklers

Blog Post created by lorrainecarli Employee on Jul 7, 2010

The National Fire Protection Association (NFPA) has issued a safety alert recommending that residential fire sprinkler systems containing antifreeze should be drained and the antifreeze replaced with water. The alert follows a research study and an initial set of fire tests conducted after a fire incident raised concerns about antifreeze solutions in residential sprinkler systems. The incident involved a grease fire in a kitchen where a sprinkler with a high concentration of antifreeze deployed. The fire resulted in a single fatality and serious injury to another person.

"Fire sprinklers are one of the most effective ways to save lives and property from fire,” said James M. Shannon, president of NFPA. “Until we can provide further information based on additional research that is currently underway, we are urging the public to continue the use of sprinklers but to follow our interim safety guidelines by removing antifreeze if it is in their sprinkler systems."

According to NFPA, the home is the place where most fire fatalities occur, and when home sprinklers are present, the risk of dying in a home fire decreases by 83%.

The full press release is available on NFPA's website.

NFPA offered the following interim guidance on residential sprinklers:

Fire sprinklers are extremely effective fire protection devices, significantly reducing deaths, injuries and property loss from fire.

These systems should not be disconnected.

Until the results of further testing on antifreeze are available, NFPA recommends the following:

  • If you have, or are responsible for, a residential occupancy with a fire sprinkler system, contact a sprinkler contractor to check and see if there is antifreeze in the system.
  • If there is antifreeze in the system, as an interim measure, drain the system and replace it with water only. Problems associated with freezing of sprinkler pipes can be mitigated by alternative measures such as insulation. NFPA hopes to provide further guidance based on additional testing before the winter freezing months.
  • If you are putting in a new residential sprinkler system, design and install a system that does not require antifreeze.

“We are providing this safety alert as interim guidance based on the information we have right now,” said Shannon. “As soon as more information is available, we will update the public.”

NFPA also reminded the public about basic fire safety tips for kitchen fires. All consumers should take important fire safety precautions regarding kitchen fires.

  • Have and maintain smoke alarms in your home.
  • Pay attention when you are cooking.
  • Should you have a grease fire on your stovetop, smother the fire by sliding a lid over the pan and turn off the stovetop. Leave the pan covered until the pan cools completely.
  • Never put water on a grease fire or use a fire extinguisher on a grease fire.
  • Never attempt to carry a flaming pan across the kitchen.
