The second only to life safety is the protection of _________ during fire fighting operations
Property
A natural or man made barrier that will prevent the fire from encircling the vehicle and crew
Anchor point
Ability of an apparatus to traverse a body of standing water
Fording
Overhaul of a fire or hazardous material scene
Mop-up
Procedure by. Which available resources responding to a fire or emergency incident are held in reserve at a location awaiting assignment
Staging
Often used on multi unit response off two or more units. First arriving vehicles of each type proceed directly to the scene, and the others standby a block or two and await orders
Level 1 staging
Used on large scale incidents where a large number of fire and emergency services companies are sent to a specified remote location to await assignment.
Level 2 staging
Company officer of the first arriving unit at the staging who takes command of the area and is responsible for communicating available resources and needs to the operations section Cheif
Staging area manager
Location at which the primary incident management logistics functions are coordinated and administered
Base
The most common incidents on roadways are _______ _________ and/or _______ _____
Traffic accidents, vehicle fires
A major hazmat incident has 3 zones
Restricted (hot) zone
Limited access (warm) zone
Support (cold) zone
What are some basic principles to be considered when responding to a hazmat call
Approach from upwind and uphill
Do not drive the apparatus directly into the scene until material involved can be identified
Obtain info regarding wind speed and direction from the dispatcher
This zone is safe for personnel to enter into briefly without special protective clothing (hazmat)

If feasible, pull the apparatus ____ the building gaining a 3 sided view
Investigation
Past
When fire conditions are evident upon arrival, the driver should place the apparatus in a safe position that includes…..
