There was a red-hot demonstration by firefighters at the Honolulu Fire Department's Waipahu Training Academy on Friday.

The Honolulu Fire Department tested two rooms. One room had a sprinkler system and the other did not.

HPD started a fire in the room without a sprinkler head first. In just in three minutes, the entire room was engulfed in flames. HFD said you are lucky if firefighters can get to your house in 5 minutes.

Battalion Chief Socrates Bratakos with HPD said, "We've got to process the call, they've got to get dressed, and we got to send the truck and van. Our fastest guys are going to take 6 to 7 minutes until they can get there and put water on the fire."

In the second room, a sprinkler head activates in less than 30 seconds. The fire is quickly extinguished.

The fire department and the Hawaii State Fire Council did the demonstration to show the importance of fire prevention, but they also did it because they are upset about a state law adopted earlier this year.

The new law prohibits counties from mandating sprinklers in single-family homes, something that can cost thousands of dollars to install.

"Those who say that we shouldn't be mandating fire sprinkler systems are arguing about the cost. I put that argument against, what's the cost of your own family? There's no comparison," said Nestor Garcia, Honolulu city councilman.

The fire department says more than 80 percent of all fire deaths occur in homes.

Garcia said, "What I want is to make sure we can have a discussion, so we can at least discuss it at the county level without having the state law hanging over us."
