Hoses of red, silver, green, blue, orange and yellow will soon color the waterjetting landscape, as the industry begins to adopt a new safety scheme designed to better identify the pressure in use.
The Board of Directors of the WaterJet Technology Association – Industrial & Municipal Cleaning Association approved the new color-coding safety scheme at its meeting in September.
|Hoses will be color coded for various pressures.|
By coloring entire hoses, rather than using different colored stickers on uniform hoses, the association hopes to help contractors avoid the danger of using a hose at the wrong pressure.
The board approved adding wording regarding the color-coding scheme to Recommended Practices for the Use of High Pressure Waterjetting Equipment.
The new text reads:
“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 following color code scheme 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.”
Effective immediately, the new wording will be added to the current edition of the Recommended Practices manual.
The 2011 edition of the manual was recently revised. The fourth edition, compiled by the SJTA-IMCA Safety Committee, includes a new section on the operation of automated equipment and other significant changes.
High Pressure Waterjetting (HPWJ) and Ultra High Waterjetting (UHPWJ) are becoming more common in industrial painting for surface preparation of steel and removal of coatings containing lead and other heavy metals.
Because this method carries the same responsibilities and obligations for waste management as abrasive blast cleaning, JPCL and SSPC recently hosted a webinar on managing and disposing of the waste from such projects.
A free webcast of the webinar is available.
