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.”

Hydroblast is a member of The Water Jetting Association. This means we have access to training courses that can be delivered at the Hydroblast head office or on-site.
The first, core module is in Safety Awareness, which must be completed every three years. Following this, four further modules are available:
- Drain and sewer cleaning
- Tube and pipe cleaning
- Surface preparation
- Cutting and breaking
One of the main aims of water jetting training is to promote and encourage water jetting safety. Since The Water Jetting Association produced its first Code of Practice for ultra high-pressure water jetting equipment in the 1980s, there have been numerous updates, and regular legislative changes. Hydroblast can help you to keep up to date.
The first step is to complete the Safety Awareness course, which is valid for three years from successful completion. At this point the candidate is awarded a certificate and ID card as proof of their qualification.
Once this initial course has been successfully completed, the candidate has three years in which to complete any of the subsequent modules. All successfully completed modules will be added to their ID card as proof of competence.
Water Jetting Injury
Please remember – an injury incurred during water jetting must be tended to immediately by a qualified medical practitioner. High-pressure water jetting can be dangerous, and injuries are likely to be severe due to the deep penetration of the water jet.
