MYTH
The extra cost of installing a nitrogen system for your fire protection system is not worth the investment.

FACT
Corrosion is fueled by the interaction of unprotected metal, oxygen, and water. Allowing oxygen into your fire protection system actively feeds that formula, whereas nitrogen-protected systems inhibit one of the ingredients that contribute to corrosion build-up. In addition to the invaluable human dangers and damages associated with a failure of an existing or rapidly deteriorating sprinkler system, the cost of a replacement system or a fire emergency getting out of control because of a compromised sprinkler system would far exceed the cost of a sprinkler system protected with Nitrogen.

MYTH
Fire sprinklers are triggered by smoke.

FACT
Smoke does not set off fire sprinklers – heat does.

MYTH
The primary function of sprinkler systems is to put out fires.

FACT
While sprinklers help to extinguish flames, the chief purpose of a sprinkler system in a fire is to cool the temperature to suppress/contain the fire by reducing the rate of heat release.

MYTH
If one sprinkler goes off, they all do.

FACT
Sprinklers activate independently, one at a time, triggered by heat.

MYTH
Water damage from sprinklers exceeds fire damage.

FACT
The property damage in a structure with sprinklers is far less than the typical loss associated with a fire in a structure with a failed/nonexistent sprinkler system. Not to mention the invaluable threat of human danger caused by fire.
