Fire Hose Testing 

 

WARNING 

Hose Testing Hazard.  May result in serious personal injury. 

Due to a potential for catastrophic hose failure during service testing of fire hose, it is vital that safety precautions be taken to 
prevent exposure of anyone to this danger.  Fire pumps on fire department apparatus are not designed for and should not be 
used for service testing of fire hoses.  Hose testing machines should be used for service testing of fire hoses.  
 
 
 
NFPA 1962 

Standard for the Inspection, Care, and use of Fire Hose, Couplings, and Nozzles and the Service Testing of Fire 

Hose

 provides requirements and testing procedures for service-testing fire hose at least annually.  NFPA 1962 includes 

procedures for service testing with either a hose testing machine or with a pump on a fire department fire apparatus.   

WARNING 

Pressure Hazard.  May result in serious personal injury.

  

If a fire pump on a fire department apparatus is used for service testing of fire hoses, the procedures in NFPA 1962 

MUST 

be followed

 including the use of a fire department gate valve with a ¼-inch (6 mm) hole drilled through the gate installed 

between the fire apparatus discharge outlet and the hose test layout to prevent a volume surge from the pump in the event a 
hose bursts during testing.   
 
 
 
During fire hose testing with a fire pump on a fire department fire apparatus, the fire pump is required to be operated at high 
discharge pressure with little or no flow out of the apparatus.    

WARNING 

Scalding Water Hazard.  May result in serious burns.

 

If a fire pump on a fire department apparatus is used for service testing of fire hoses, pump discharge water must be 
circulated through a by-pass system or discharged through a slightly open discharge valve, or some other provision must be 
used to prevent overheating.  If the pump runs for a few minutes without adequate flow through the pump, water may be 
heated enough to scald someone when a valve is opened.     
 

CAUTION 

If a fire pump on a fire department apparatus is used for service testing of fire hoses, operating the pump at high discharge 
pressure with little or no flow may result in severe damage to the pump.
