High Pressure Sprays Safety Combustible and flammable chemicals become explosive when sprayed. Appropriate safety precautions must be designed into the process and equipment if these materials are to be used. High-pressure liquid streams can be dangerous to operators. This is especially true of needle jet configurations. Appropriate operator protection must be provided. High-pressure systems must be designed with mechanical components that can withstand operating pressures. For example, do not use PVC piping downstream of a high-pressure pump.
