Roadway incidents

A

Use engine to barricade/block or divert traffic
Consider engine noise and exhaust
Spills or leaks- uphill upwind
If apparatus is facing traffic consider turning off headlights

21
Q

Engine Positioning
Structure fires

Single story structure

A

First arriving engine and ladder should be spotted in front of structure in most cases position engine and hoses while leaving room in front of structure for ladder

22
Q

Engine Positioning
Structure fires

Multistory Structure
