On September 10, 2012, the WJTA-IMCA Board of Directors approved the addition of new language to section 14.17.1 of the Recommended Practices for the Use of High Pressure Waterjetting Equipment. Section 14.17.1 addresses a color coding scheme for pressure hoses. The goal of this recommended practice is to help ensure on-the-job safety by making the various hoses more easily identifiable on sight.
Section 14.17.1 is reprinted below. The language appears in red.
Pressure hoses are designed for various pressures and could present a safety hazard if not used for the designated working pressure. In order to better identify the pressure in use, it is recommended that the color code scheme listed in the box to the right is used for the applicable maximum working pressure.
The color scheme should be easily identifiable at least two feet from both hose ends. January 1, 2013, is the effective date for implementation. Abrasion-proof stickers are acceptable in the interim.
If working between pressures in the chart, ensure that all hoses are color coded to indicate the higher maximum rated pressure above the intended working pressure. For example, if the desired working pressure is 12,000 psi, use a hose rated at the next highest pressure.
The new language appears in the latest edition of the Recommended Practices for the Use of High Pressure Waterjetting Equipment.
The Recommended Practices manual is available through the WJTA-IMCA online store. For more information contact the WJTA-IMCA office.
