Wildland Spotting Considerations: Structure Protection
+ Avoid blocking road
+ Keep cab doors and windows closed
+ Remove nearby fuel
+ Lee Side (spot?)
+ Do not spot near power lines, trees, LPG tanks
+ spot close to structure to utilize short hose lines

Pumper Testing: who does certification testing?
Underwriters Laboratory
171
Annual Pump Test: Dry Vaccum Test
Drain pump and connect two 10' sections of hard suction with cap.
Develop 22" Hg with priming pump. (NFPA)
Shut off engine and listen for leaks.
Cannot lose more than 10" Hg in 10 minutes.
172
Annual Pump Test: Priming Test
with 20' of dry hard suction attached, operate priming pump until water is discharged from priming pump discharge
Pumps rated less than 1500 GPM have 30 seconds to complete
Pumps rates 1500 GPM or over have 45 seconds to complete
173
Annual Pump Test: Capacity Test
Pump must flow rated capacity at 10' draft at 150 psi for 20 minutes at less than 80% of peak engine RPM
174
Annual Pump Test: Relief Valve Test
Relief valve must operate at proper pressure and not exceed set pressure by 30 PSI
175
Annual Pump Test: Overload Test
With same setup as Capacity Test, throttle up to obtain 165 PSI at rated capacity
176
Annual Pump Test: 250 PSI Test
Place transfer valve in pressure, run pump up to 50% of capacity at 250 PSI for 10 minutes
177
Annual Pump Test: 200 PSI Test
Check acceptance sheet to see if tested in volume or pressure and run pump up to 70% of capacity at 200 PSI for 10 minutes.
178
Annual Pump Test: Tank to Pump Test
300-750 GPM pumps must pump 250 GPM from tank.
| 751 GPM pumps and over must pump 500 GPM from tank.
