Cold weather Flashcards
When does the cold weather policy go into effect?
at or below 32 degrees
At what temp should apparatus with foam or water not leave the station for non-emergency ops
20 degrees
What should happen to unattended vehicles without foam or water based on BC discretion?
They must be left running with the heat on and the doors locked
What are the cold weather operations steps for apparatus with tanks?
Open the engine cooler valve, all discharge valves and caps, all intake valves
and caps, all drain and bleeder valves, and the master drain valve.
After draining the system, close all drains and bleeder valves, close the master drain valve, install all caps, and fill the pump with water. Open the tank-to-pump valve and tank recirculation or refill valve and leave them
open. Having both valves open will create thermal circulation with the warm water in the tank when responding emergent.
If a discharge valve or fitting leaks, notify fleet. It may only need a slight adjustment to correct the problem.
Check the “On Spot” chains for proper operation and periodically rinse the chains with warm water
What can be done to prevent the caps from freezing?
A small
amount of WD-40 can be used to lubricate the caps and prevent
them from freezing. Please do not use white lithium grease as it
collects dirt and grime that causes the caps to bind.
What is the purpose of draining the system in cold weather
This step will ensure the entire system is drained to prevent any
damage to lines and valves outside the pump house that could have
water trapped and frozen if not drained in the station
What should happen when the apparatus arrives on scene during cold weather?
chock the unit, engage the fire pump, and
raise engine rpm to 1,000 rpm. This will supply warm water to circulate
through the pump while on scene.
What should be done daily to the air tanks for cold weather ops
Bleed air tanks on the apparatus daily to remove moisture.
What should be done to the Husky 12 in cold weather ops?
a. Confirm the Husky 12 Foam system is off.
b. Drain entire Pump Manifold and Foam Pump Manifold
After completing Pump Operations, open the Flush Valve Drain and the Manifold Drain to relieve pressure from the system.
What should happen to medical gear of the apparatus?
should be moved inside the cab if carried in an outside compartment when temps drop below 20 degrees
