If a large portion of a bar joist metal deck roof building is already heavily involved on arrival (__ % or more of large buildings) you may not be able to preform roof ventilation

For bar joist metal deck buildings what is needed is an evaluation of the extent of fire involvement, coupled with a _____ fire attack

You should start __ stores over from a fire store in row of attached stores, this way you can cool the unprotected steel joist

In a metal deck roof fire, if there is not heavy fire in the contents below FFs on the roof will be needed to cut through the _____ and expose the burning tar. You only need to get the _____ up

When making the insulation cuts, initially pull up a relatively small section (___ ft) in order to determine which way the corrugating runs

After finding which way the corrugating runs then make long __ ft wide strips _____ to the corrugation to open as many little valleys as possible

The ____and cooling power of the 2 1/2 in hose will be helpful here, especially in many of the high ceiling structures, such as _____ and big box type stores where this type of fire is most likely

While most prevalent in new construction, lightweight construction is used in renovations due to the ____ and ease of installation

As a guide whether to send in FFs in occupied lightweight structures try to determine wether fire has penetrated ___ attacking the trusses

Opening up a buildings ____ and directing a stream into the truss loft may be quite useful

If a life hazard is known or suspected efforts should be coordinated to provide the ____, most direct approach to that location without placing FFs in undue danger

On larger buildings where vertical ventilation is deemed to dangerous _____ ventilation from a platform basket may suffice

After the fire is knocked down, place the emphasis on ____ the structure

Proceed slowly when assessing the structure providing ____ window ventilation and maximum ____

Operate with the absolute _____ of personnel in the danger area until the trusses or other lightweight elements have been exposed and examined

Provide emergency ____ as necessary in the building

Sweeping the ceiling with large streams also helps reduce the ___ problem with metal deck roofs— the metal deck roof fire. This can occur without any major involvement of the items directly below and can result in the extension of fire over the heads of FFs who assume all is under contr

It is critical that FFs identify such construction while it is in ____, before the fire; _____ it for future reference and _____ its presence to every possible responding ff. _____ officers must establish policies for operations at such structures
