9.  Do not close down or restrict discharge hose.  Be careful of 

discharge hose whipping under pressure. 

10. PUMP TOWED BEHIND VEHICLE 

a.  Make sure hitch is properly attached. 

b.  Always attach safety chains. 

c.  Check tires for proper inflation and road worthiness. 

d.  If  towing on the highway, make sure the trailer meets Department

11. Make sure lifting device’s fasteners are tight each time before lifting. 

 

B. GAS/DIESEL ENGINE POWERED PUMPS 
 
1. EXHAUST GASES 

a.  Never operate in an enclosed building or area where exhaust gases 

can accumulate. 

b.  Do not breathe exhaust fumes when working in the area of the 

engine.  (Exhaust gases are colourless, odourless and deadly 
poison.) 

c.  Never operate near a building where exhaust gases can seep inside, 

for example: through an open window or a door. 

d.  Never operate in a pit or sump without making provisions to suck the 

exhaust gases out. 

 

2. EXHAUST SYSTEM 

a.  Keep exhaust system components tight and in good working 

condition. 

b.  Exhaust system parts get very hot and stay hot for some time after 

shutting the engine off – do not touch. 

 

3.  FUEL 

a.  Never add fuel to the tank while the engine is running.  Stop engine 

and allow it cool.  Avoid spilling fuel! 

b.  Make sure fuel lines and fittings are tight and in good condition.
