text: Hydraulic testing is a hazardous process and should be performed with caution by competent personnel. Adhering to prescribed procedures defined in relevant technical standards appropriate to the specific application and jurisdiction will usually reduce these risks to an acceptable level.
  * A leak of high pressure liquid can cut or penetrate the skin and inject itself into body tissues. This can cause serious direct injury to the operator, and if the fluid is toxic or contaminated there will be additional adverse effects. 
  * A pressurised hose that is not securely attached or which fails under pressure may whip around spraying water or oil and could hit someone and cause injuries. A  can be used to restrain such hoses. 
  * Enclosing the components to be tested, hazard signage, use of appropriate personal protective equipment and providing barriers to access for non-essential personnel are common precautions.
  Equipment:
  * Pressure gauges
  * Water supply
  * Pumps and hoses for water filling 
  * High pressure pump and hoses for pressurising
  * Means of measuring volumetric expansion when applicable
