A:✔The analog in-line pressure gauge is used to monitor pressure and flow being delivered from the standpipe outlet.

C: The multiversal has two 3” inlets. The maximum pressure to be supplied to the appliance base is 200 psi.
D: The Bresnan distributor is supplied with a 2 ½” hose. A shut-off should be placed one length from the distributor.
Explanation:
A) The analog in-line pressure gauge is used to monitor PRESSURE being delivered from the standpipe outlet. Like the digital in-line gauge, it does not regulate water flow; it simply monitors the pressure of the water supplied. Unlike the digital in-line gauge, the analog gauge DOES NOT measure water FLOW.
D Note: To properly use the Bresnan distributor, it should be lowered into the fire area via an opening and the shut-off should be opened to begin water flow. The distributor is lowered until it hits the floor, then raised several feet to position for optimal distribution.

Ventilation at nonfireproof multiple dwelling fires must be carefully conducted. Which of the following choices is not in accordance with Department directives?
A: Windows directly exposed to fire across shafts or directly over the fire should not be opened until the exposing fire is controlled either by partial or complete extinguishment or by having a charged hand line at these extension points.
B: When using a fire escape for access to different floors, never vent a window that could allow fire to cut off the line of retreat.
C: When venting the windows of the fire apartment from directly above by use of a 6` hook and an intense fire is suspected, the possibility of fire rolling up the side of the building when air is admitted must be considered. For safety, look down at the window to be removed, measure the distance with the tool, pull your head back in the window and then swing the tool through the window below.
D: When venting the windows of the fire apartment from the fire escape first check them for heat. See if they show cracks from the heat and look for discoloration of the glass (black and tar-like) from the heat. If above observations indicate extreme heat, the fire may momentarily vent itself or light up as you ventilate.

If above observations indicate extreme heat, the fire may momentarily vent itself or light up as you ventilate.
D Note: To safely vent both windows, first break the window off the fire escape and then the window on the fire escape. If the fire escape window is vented first, fire or heat from this window may prevent venting the other window. NOTE: EEWs may not give any of these indications; contact Ladder Company Officer before VEIS.
A Note: It may be necessary to close windows and remove drapes, curtains, etc.
C Note: The firefighter’s hand and arm will be protected by their clothing.
