The North Charleston Fire Department will conduct a “live fire” demonstration Wednesday to help residents understand the difference a residential sprinkler system can make.

In the demonstration at 5 p.m., two rooms will be set up in the parking lot of the North Charleston Fire Museum, at 4975 Centre Pointe Dr. One room will have a residential sprinkler system, the other will not, and both rooms will be burned.

The side by side fires will show how long it takes for a room to “flash over” — meaning a temperature of more than 1,400 degrees had been reached — versus a room with a residential sprinkler system.

The South Carolina Fire & Life Safety Education Association and the South Carolina Fire Sprinkler Coalition are partners in the demonstration.
