Many accidents occur every year through careless use of mechanical equipment. You can avoid hazards associated with high-pressure equipment by always following the safety precautions listed below.
Shut down or disengage the pump and all accessory equipment before attempting any type of service. Failure to do this could cause electrical shock or injury from moving pump parts or components under high pressure.
Bleed off all pressure to the pump and piping before attempting any maintenance to the pump. Failure to do so may spray water or chemicals at high pressure onto service personnel.
Never operate the pump without a pressure relief valve, burst disc, or other type of properly sized overpressure safety device installed.
Always use a pressure gage when operating the pump. The pressure must never exceed the maximum pressure rating of the pump or damage may occur. This damage can cause leakage or structural damage resulting in injury to personnel.
Insure that no valves are placed between the pump and pressure relief valve. If the pump is started with a closed or restricted valve in line before the pressure relief valve, the pump may build up pressure in excess of its rated limits and burst causing injury to personnel.
Use shields or covers around pumps when pumping hot water, chemicals, or other hazardous liquids. This precaution can prevent the exposure of service personnel to these fluids should leakage occur.
Always use guards on all belt drives and couplings. Guards can prevent personnel from becoming entangled and injured in rotating parts.
Use extreme caution with solvents used to clean or degrease equipment. Most solvents are highly flammable. Observe all safety instructions on packaging.
Never modify the pump to perform beyond its rated specifications.
