• direct stream at base of flames
• hold upright
• nozzle held with STRONG HAND

-INSPECT EACH TOUR/throughly examined mONTHLY

Question 3

Answer 3

purple k or dry chem with sodium bicarbonate

• activated by separate nitrogen cylinder
• stretch entire amount of hose (100 feet)
• charge unit by opening valve on nitrogen cylinder
• always stretch before charging

Question 4

FLAMMABLE LIQUID SPILL..

Answer 4

• approach from upwind side
• nozzle at 45 degree angle to the ground
• 10 to 12 feet from front edge of fire area
• direct stream of dry chemical 6 inches ahead of flame
• rapid side to side while advancing back of edge..each sweep slightly wider
• do not raise nozzle and chase fire ball

Question 5

Flammable liquid spill with obstacle..

Answer 5

2 guys with extinguishers

• 45 degree to ground
• 10 -12 feet
• 6 inches
• advance slowly around each side , each operator cover 2/3 of the fire area
• aim both at base of fire and then into container, if it contains burning liquid

Question 6

Flammable liquid pressure fire..

Answer 6

• approach from upwind
• 15 feet from edge
• direct stream at fuel source , then move down to escaping fuel

-in some cases, it may not be desirable to extinguish fire unless fuel supply can be shut off

Question 7

FLAMMABLE GAS PRESSURE FIRE..

Answer 7

• approach from upwind
• direct dry chem at fuel source, then move UP to escaping gas
• -some cases, not desirable until fuel is shut off

Question 8

LIQUIFIED PETROLEUM GAS FIRE USING WATER..

Answer 8

–LPG fires should not be extinguished unless immediate fuel shutoff is possible …LPG vapors ARE HEAVIER THAN AIR and can flow downward considerable distance

• open the water nozzles first and adjust to FOG
• then open dry chem and direct stream at the fuel source

-simultaneous use of water and dry chem coming to make a highly effective fire fighting tool..water acts as a coolant and heat shield and dry chem provides the means for rapid extinguishment
