Stabilize once scene and extrication needs are assessed!
stabilize involved vehicles to prevent:

———————————————————————–
Never shake or test stability of vehicles
Always stabilize prior to entry
What is Vapor Density?
Vapor Density describes the density of gases in relation to air!
Air has been assigned a vapor density of 1.
Gases with a vapor density of less than 1 will rise,
while those having a VD greater than 1 will sink.

5 characteristics of flammable gases?
- Pressure
- Diffusity (tendency to spread freely)
- Low boiling points

Includes certain warfare agents and water reactive materials which produce toxic gases upon contact with water. - Initial isolation distance is the distance (radius) which defines a circle in all directions from the actual spill/ leak source.
- Protective action distance is the downwind distance from the actual spill/leak source within which protective actions could be implemented.
