Elimination, Substitution, Engineering controls, Administrative controls, PPE

Operational element that provides a framework for maintaining control of personnel assignments and actions

ICS

All incidents should have a

IAP

What is required for incidents with multiple operational periods or those involving hazardous materials

Written IAP's

When operating in the hot zone, units should be within what range of each other

Visible range

Common barriers to communication

Horizontal movement of a layer of hot gases and combustion by products from the center point of the plume, when the vertical development of the rising plume is redirected by a horizontal surface such as a ceiling

Ceiling Jet

The tendency of gases to form into layers according to temperature

Heat Stratification and Thermal Balance

Rapid transition from growth stage to fully developed stage is known as
