1. Identify FIVE requirements for a MWS apparatus that can be found in NFPA
1901 ANS >>> 1. An MWS apparatus equipped with a fire pump must have a tank
to pump line at least two inches in diameter and be capable of supplying the pump
with 500 GPM until at least 80% of the tank is emptied.
2. An MWS apparatus must be equipped with at least one external fill connection
connected into the tank that allows the tank to be filled at a minimum rate of 1000
GPM.
3. The external fill connection should be equipped with a valve, strainer, and a 30

, degree elbow.
4. Valves that are three inches or larger must be of the slow closing design.
5. An MWS apparatus must have at least three large tank discharges capable of
discharging 90% of the tank volume at an average of 1000 GPM.
2. When Checking the left front or right front side of the fire apparatus, don't
forget to inspect the ANS >>> ANS >>> saddle tanks
3. Daily inspection ANS >>> Ensure auxiliary fuel tank is full
Operate pump primer
Inspect auxiliary winterization system.
4. Weekly Inspection ANS >>> Clean intake strainers
5. Pre-service pump certification test are conducted by ANS >>> ANS >>> An
independent testing agency

ratus service testing, the water surface must not be more than feet above
the centerline of the pump intake and the water must be at least feet
deep. ANS >>> 10 Feet above
4 Feet deep
7. If the engine speed check proves the MWS apparatus is running at a differ-
ent speed than what which it was originally rated, you need to? ANS >>> Stop the
testing until the problem is corrected.
8. A year has passed and its time conduct the annual vacuum test on your
departments MWS apparatus. You're following the procedures for conducting
the vacuum test and you've already checked for and removed foreign matter
