It’s critical to KNOW YOUR FLOW!!
1. Desired Amount of GPM
2. Desired Location/Reach of the Stream
3. Desired Nozzle Reaction/Mobility
All three are CRITICAL when determining your hose & nozzle selection.
WATER KILLS FIRE…..
When catching a hydrant always get plenty of LDH hose around the hydrant. It takes ten feet when catching a corner or 180 catch. It is very easy to come up short and create an unwanted kink or kinks that could cost you greatly in your available fire flow.
Also consider later arriving companies they may be blocked by supply line. When possible loop your LDH to the inside or soil side and not out into the street. The above photo is an example how the line can greatly close down a street. If we were to loop inside it would allow for more street access of later arriving companies.
Does your FD perform interior operations at Commercial Structure Fires?
Would you SEARCH the first floor bedroom?
What are your concerns here? When can you vent a TRUSS ROOF? What’s more dangerous; a Residential Truss roof or a Residential Truss floor?
When do we stretch back up Line? Who mans/staffs back up line? What if fire is getting knocked down; do we still stretch it? What size and type? Where should the back line go?
