As evidenced by a number of recent well publicized fires, smoke and flames find their way through a building at an incredible speed. Even the best active fire prevention systems like smoke detectors, alarms and sprinklers, can be rendered ineffective by lack of power, water pressure, or improper maintenance. The result can be disastrous... loss of property, business, and worst of all loss of life. Because "Active" fire prevention methods can fail when they are needed most, the codes now require the use of "Passive" fire prevention systems known as "Firestopping Materials". Their purpose is to compartmentalize and contain a fire to its smallest possible area without the help of any secondary systems.
