Answer 14

BATTALIONS, HAZ MAT CO 1, HMTU, RESCUE , LADDER (does not mention squad/engine…NEW)

• provides “GEIGER COUNTER” like ticking sound that INCREASES FREQUENCY when gas source as low as 20 ppm of METHANE detected.
• lithium ion battery
• INTRINSICALLY safe
• NOT detect CO
• RECHARGE 2 to 5 hours /LED GREEN FULLY CHARGED
• 20 hours continuous life
• LED blinks green , must recharge, IF AFTER 5 HOURS THERE IS NO SOLID GREEN, NOTIFY HAZMAT

Question 15

-UNIFORM ticking should indicates fully warmed up/red LED will also begin to flash
INCREASE IN TICKING SOUND AND FLASHING OF LED INDICATES YOU ARE APPROACHING LEAK

• DECREASE IN TICKING AND DECREASE IN FLASHING LED indicates you are moving away from the leak
• replace with HAZMAT/ONE FOR ONE
