The Water Jetting Association Blue Code Of Practice
You can buy copies of the Blue WJA Code of Practice (HP) from the Association’s website, which you can find here.
We are extremely conscientious about adhering to the rules laid out in section 6.2.4:
“The potential reaction force of any water jetting equipment must be considered as part of the Risk Assessment and must take into account the comfortable physical capabilities of the individual over the exposure time as well as the work location and any supportive structure. Safe Systems of Work must be developed and followed to ensure that jetting gun operators are not subjected to forces that would cause a risk to their safety. BS EN 1829 – 1 recommends a maximum reaction force of 250N.”
