Training Bulletin #1: Exploring the Use of 1-Inch Hose in Firefighting

Question 1

Definition of “indirect method” of applying water?

Answer 1

“The cooling of the area directly ABOVE the fire, in a confined space, using a fine spray or fog stream.”

Question 2

Note**

Answer 2

“Conventional method” is aiming stream directly to the seat of the fire.

Question 3

Note**

Answer 3

The time required for knock down of and the amount of water used for the “indirect method” was proportionate to the degree of VENTILATION present.

Question 4

Note**

Answer 4

With a small vertical opening present, the fire could still be knocked down by the “indirect method” but some difficulty was encountered. Anything more than a minimum vertical opening required the use of the conventional method to knock down the fire.

Question 5

What are the two conditions necessary for the “indirect method” to be successful?

Answer 5

• A fire area which has not vented vertically, and preferably not at all.
• A hot fire with an accumulation of heat.
• When the above conditions are present in a RELATIVELY SMALL and CONFINED area, a quick knock down may be effected with LITTLE water damage, LESS fire damage, and LESS punishment to the men than if the conventional method were used.
