At a fire operation, when the Officer or ECC of the first arriving pumper has no viable water source and transmits a 10-70, a relay operation may need to be implemented. Which choice below is incorrect?
A: The next arriving pumper, designated as the Water Resource Unit, upon hearing signal 10-70 must find a viable water source.
B: Generally, the Supply Pumper and the Operating Pumper must remain in the Volume Position.
C: At Standpipe operations where head pressure needs to be overcome, the Supply Pumper remains in the Volume position and the Operating Pumper must be in the Pressure position.
D: If the intake pressure gauge reading drops below 15 psi on the Operating Pumper, the ECC of the Operating Pumper should inform the IC that the hydrant’s supply limit has been reached
D
Explanation:
If the intake pressure gauge reading drops below 15 psi on the Operating Pumper, the ECC of the Operating Pumper should request the Supply Pumper to increase throttle (tap-up pro-pressure governor) in 10 psi increments as needed. If the Supply Pumper’s intake pressure gauge drops below 15 psi, the Supply Pumper ECC should contact the Operating Pumper ECC and the Incident Commander and inform them that the hydrant’s supply limit has been reached.

The department has provided each ladder company with two types of natural gas investigative tools. Which choice below is CORRECT regarding the Natural gas meter?
A: The natural gas meter uses an audible tick that increases in frequency as it approaches the source of escaping gas.
B: The natural gas meter is a superior tool for identifying areas in which it is no longer safe to operate
C: The natural gas meter should be used at an appliance, pipe or crack as high levels of gas are expected at these locations.
D: The natural gas meter is used to determine the location of a natural gas leak.
B

Ladder 100 is operating 2nd due at a fire on the top floor of a brownstone type rowframe. Which action performed by Ladder 100 is incorrect?
A: The company split and examined exposures for extension to the cockloft with the inside team operating in the most severely threatened exposure.
B: If Ladder 100’s inside team determines that a stop of the fire can be made in the exposure, a hand line must be called for.
C: Ladder 100’s roof firefighter made an examination of the returns of the exposures. Returns remote from the fire must be checked for extension to the cockloft.
D: Because there was no rear fire escape, Ladder 100’s OV firefighter proceeded to the roof.
C
Explanation:
C. Ladder 100’s roof firefighter made an examination of the returns of the exposures. Returns remote from the fire SHOULD BE AVOIDED AS THIS ACTION COULD SPREAD THE FIRE IN THE COCKLOFT.
NOTE D: WHEN THERE IS NO REAR FIRE ESCAPE, THE 2ND OV SHALL TEAM UP WITH THE CHAUFFEUR FOR EXPOSURE EXAMINATION OR THEY SHALL PROCEED TO THE ROOF.
EITHER OPTION IS CORRECT

A: The MSA Altair Digital Gas Meter does not replace existing Sensit TKX Detectors, but must be used in conjunction with the Sensit TKX Detector
B: The MSA Altair Digital Gas Meter is equipped with two senors, one for combustible gas and the other for oxygen
C: When the MSA Altair Digital Gas Meter is OOS, the officer on duty shall not send the meter through the bag for a replacement, instead the officer on duty shall call Haz-Mat Operations and request a replacement
D: The MSA Altair Digital Gas Meter can be used to detect gases other than natural gas
D Explanation: A- sec 1.1 B- sec 1.2 C- sec 3.1 D- The meter should NOT be used to detect gases other than natural gas..... sec 1.2 Emergency Procedures Natural Gas add 2

You are working in Ladder 171 and your unit is operating at a fire in a taxpayer which is now under control. As a vent support unit, you are tasked of coordinating the ventilation of the 100x100 building where CO readings have been holding in the 100 PPM area. Which statement regarding using fans for ventilation is CORRECT?
A:✘Gasoline powered positive pressure fans will not significantly reduce the CO levels due to the emissions produced by the fans.
B: In the area where the fire was controlled by sprinklers, the exhaust area should be as low as possible to minimize the smoke damage to the structure.
C: A rule of thumb is the air inlet where the fan is located should be double the size of the exhaust opening.
D: Fans blowing fresh exterior air into the structure have shown to be 75% more efficient than negative pressure ventilation.
D
Explanation:
AUC 349 – POSITIVE PRESSURE FANS
D IS CORRECT– 9.3
A – If CO levels are 0-60 range, PPF will not significantly reduce those levels. The levels in the question are at 100. 8.2
B – Exhaust area should be as high as possible 9.2
C – OPPOSITE – Exhaust opening should be double the size of the opening where the PPF is located 9.2
