High Pressure Waterjet Hose Color Codes Cheat Sheet (DRAFT) by [deleted]

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Introd­uction

Color coding scheme was added to the Recomm­ended Practices for the Use of High Pressure Waterj­etting Equipment;

Pressure hoses are designed for various pressures and could present a safety hazard if not used for the designated 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 seen by a color spanning two feet from both hose ends.

MANAGING RISKS - LIMITS AND USE

A high pressure water jetting system should not be used unless it:
has been inspected or serviced in accordance with the manufa­ctu­rer’s recomm­end­ati­ons,and
is free from any fault identified at the last inspection or service which may adversely affect the perfor­mance and safe operation of the equipment.

SAFEGUARDS

Anyone using high pressure water jetting equipment should follow these safety recomm­end­ations:
Where necessary all equipment near jetting operations should be shielded or protected from debris and the ingress of water from operating the jetting equipment.
Any essential electrical instal­lation should meet the required protection levels against the ingress of water vapour or overspray.
People other than the operating team should be kept out of barricaded work areas.
Work activities should be planned to provide safe access to the equipment and item or surface being jetted.
Overhead work should be avoided where possible, as this may cause unstable worker positi­oning and increase the risk of muscul­osk­eletal disorders.
Operators using manually operated jetting systems should be in a safe and well-b­alanced position before starting jetting operat­ions.
Jetting operations should not be performed from ladders or other surfaces not intended for use by workers, as this can lead to loss of control of the jetting equipment.
Operators should check there is no interr­uption or interf­erence to the release mechanism of any hand or foot controls that could stop the equipment operating safely and consistent with the manufa­ctu­rer’s specif­ica­tions.

Jetting operations should stop when:

conditions change or new hazards are introduced
unauth­orized people enter the barricaded area
recomm­ended safe work practices are not being followed
a malfun­ction occurs.

Depres­surized & Secure Jetting Systems when:

not in use and left unattended
components are being replaced or repairs are being made to the system.
