An evaluation of problems and conditions that affect the outcome.
When does a proper size up begin and end?
It begins the moment the alarm is received and continues until the emergency is under control.

20 minutes.

What is the deciding factor in determining tactics and procedures?
life hazard
define- L.O.T.E
Location, occupancy, time, extent of fire
What is the best method to remove the life hazard?
The best is installing a complete wet-pipe automatic sprinkler system. Other means are: imposing occupancy load restriction, improving exit facilities, specifying fire doors and partitions.
When should firefighters be committed to risk?
After an evaluation of life hazard has been made.
What is a key component to the evaluation of life hazard?
the building occupancy
