SHERIDAN — Sheridan firefighters conducted training exercises Sunday with the use of a mobile fire training trailer.
A scenario was established requiring the kind of roof ventilation procedures commonly employed during structure fires involving residential and light commercial buildings.
Firefighters used ladders to access the roof and later cut ventilation holes with chain saws.
The tactic releases hot gases and smoke from the fire, allowing firefighters to enter the building from the lower levers and suppress the seat of the fire.
Roof operations are one of the more dangerous tasks firefighters perform, Fire Marshal Brian Songer said in a press release.
The Fireblast 451 Mobile Fire Training trailer was purchased with funds from the Federal Assistance to Firefighters Grant program in the spring of 2011.
