Water Jetting Safety Requirements

Water jetting is a system of pressure washing, cleaning that is often used for cleaning roads and large structures or vehicles. Though specific governmental regulations of the industry are few, workplace safety rules are applicable to water jetting operations, and companies must comply with these as well as set their own guidelines to ensure the safety of their operating crew and laypeople.

  1. Protective Measures

    • In order to conform with the PPE or Personal Protective Equipment at Work Regulations of 1992, water jetting operations must have proper eye, foot, ear, hand, head, body and respiratory protection for all employees. British Standard Safety Goggles must be used for eye protection, rather than simple glasses, and boots must have steel toe caps and shin and foot protection if necessary. Waterproof protective clothing should be provided and worn. Respiratory equipment must be used as necessary, such as in confined spaces, to conform with the Control of Substances Hazardous to Health Regulations of 1998.

    Work Environment and Equipment

    • There must be safety barriers placed 10 meters around the work area, with signs warning "No entry for unauthorized personnel." The area should be as free of debris and rubble as possible. Ladders should never be used, rather safe working platforms when necessary. All equipment should be assembled and tested before use. There must be at least one dump safety or dry shutoff control valve for jetting operations.

    Operation

    • Before startup, ensure all crew members are in position and ready to go. Increase pressure slowly to begin, and shut down the system immediately if any faults are noticed or suspected. Do NOT try to adjust or tighten any connectors while the system is pressurized. If accessing a high structure, secure the hose at regular intervals along the way, and protect the hose from sharp edges or abrasive surfaces. Report all injuries that occur on the job.
