Safe Use of Ultra-High Pressure Waterjetting

Ultra-high-pressure (UHP) waterjetting provides an effective means for cleaning many surfaces using water pressures above 30,000 psi. UHP water jetting equipment is extremely powerful and dangerous especially because UHP waterjetting requires stand-off distances much closer than the 2-10 inches required of high pressure waterjetting. This exposes the operator to greater risk for injury since the wand end of the hose is so much closer to their body.
The topics in this article include:
- The BASICS of ultra-high-pressure waterjetting
- SAFETY HAZARDS such as injection and fatigue; how to protect yourself
- SAFETY EQUIPMENT including the proper personal protective equipment that must be worn when using UHP waterjetting equipment
- EQUIPMENT OPERATION - including proper inspection, care/maintenance and operation of equipment such as hoses and nozzles
Read the fullarticle on the PaintSquare website
to learn more aobut the operation of the high pressure pump, hoses and various tools and the amount of bursting strength required of the hose as determined by the pounds per square inch (psi).
Important safety facts and precautions for being aware of the potential for danger if a hose should rupture or if the ultra-high stream of water were to come in contact with some part of your body are discussed as well as protections that you can put in place to avoid such accidents.
A good resource for information on safety topics and more is the Waterjet Technology Association and Industrial & Municipal Cleaning Association found here: WJTA_IMCA.

In the News - Confined Space H&S Violation
"Spit and Sniff?" - Safe Test for Entering Confined Space?
September 2014 PaintSquare News
A Texas worker was asphyxiated by hydrogen sulfide as he lowered himself into a railcar to perfrom industrial cleaning.
A total penalty of $10,800 was issued by the courts to Austin Industrial for OSHA citations that played a role in the death of 31 year old Jaime Godines. Godines, an industrial worker, working for Austin Industrial under a contract at the Lubrizol plant in Deer Park, TX, died after entering the railcar which is considered a permit required confined space and requires respiratory protection. In question are the cleaning process, the lack of confined-space permit, and failure to properly identify and evaluate repiratory hazards in the workplace and train employees working with hazardous chemicals.

Proper identification of chemical hazards and proper respiratory protection are necessary to prevent health hazards when working in confined spaces, such as a railcar, tank car or other enclosed spaces.
