FIREGROUND HYDRAULICS: STRAIGHT-STREAM REACH

Last month we discussed nozzle reaction and saw how, like flow rate, it varies with the square root of nozzle pressure and how the maximum reaction can be calculated in your head. In practice, the actual reaction felt by the nozzleman is always less, because some is transmitted along the hose to the floor.
PHOENIX TOLUENE TANK EXPLOSION

PHOENIX TOLUENE TANK EXPLOSION

Rescuers in the Tower 5 incident were cognizant of the dangers posed by cutting into tanks containing residual toluene atmospheres. They remembered an incident in Phoenix, Arizona involving the ignition of toluene vapors within a steel tank during rescue operations.

FIRE FOCUS

How many handlines do you need? Start to build a needs analysis —forget the gallon formula for now. 1 st line: To the store. After getting water, see if the forcible entry problem is taken care of. If it's effected fast, begin the attack. If delayed, protect the fire escape while awaiting entry. 2nd line: Look for a visible life hazard —if on the fire escape, protect the civilians until they are off. If not present, stretch enough hose to the second floor to handle that and to go above to the third floor if momentarily needed or to complete extinguishment later.

FIRE LOSS MANAGEMENT

After the spectacular First Interstate fire in Los Angeles in 1988, passage of a sprinkler law for new and existing high-rise buildings in California seemed a sure thing. A law passed by the state legislature was vetoed by the governor, however, and a replacement law was heavily opposed and has been in the inactive file since early 1990.

This month Hot Topic initiates a survey program that elicits input from fire prevention personnel across the country. Its purposes are to let you know what others are thinking and to provide a data base for various organizations.

MEETING THE CHALLENGES OF AIRCRAFT EXTRACTION

Many firefighters have responded to a major aircraft incident. Every one of them probably never would want to do it again. Few emergency situations match the magnitude, stress, and challenges of an aircraft disaster.
