  • Page 66: General Safety Information

    General Safety Information  Safety procedures throughout this manual must be adhered to. In the case of conflicting or ambiguous instructions contact your Site Manager or Safety Manager before commencing work.  Any person operating, working with, or passing near the jetter must wear the appropriate Personal Protective Equipment (PPE).

  • Page 67: General Use Of High Pressure Jetters

    General use of High Pressure Jetters  All persons using high pressure jetting equipment must be fully conversant with relevant operating instructions, safety notes and codes of practice.  Operators must be competent in all aspects of jetter use.  Erect suitable cordons at least 10m from the jetting operation to restrict all unauthorised access.

  • Page 68: Hazards Associated With The Misuse Of High-Pressure Equipment

    Hazards Associated with the misuse of High- Pressure equipment  Never use a jetter that isn’t regularly serviced according to the manufacturer’s recommendations.  When a jetter is used to clean drains & sewers that are contaminated with a hazardous substance it is possible these may be entrained in the resulting aerosol and inhaled by operators.
  • Page 69  Never attempt to clean drains or pipes in one pass because this could lead to debris build up behind the jet nozzle causing a pressure build up in the drainage system. Be aware that a pressure build-up in the drain or pipe could cause the jet nozzle to be unexpectedly ejected back towards the operator.
  • Page 70  Never work from a ladder as the reaction force of the jetting gun could cause the ladder to fall backwards from the working area causing possible injury.  Never work from scaffolding unless it is designed, erected and managed by competent persons and it is adequately secured to prevent it being pushed over by jetting gun reaction forces.

  • Page 71: Personal Protective Equipment

    Personal Protective Equipment Before operating jetting equipment all persons must carry out a risk assessment to determine the type and level of PPE required by each member of the jetting team. This could include:  Ear protection – noise levels can be high ...

  • Page 72: Pressure Safety Devices

    Pressure Safety Devices  Pressure relief valves should be checked for functionality and certified by the manufacturer or their authorised representative at least every 6 months.  Pressure discs (burst discs) should be replaced at least every 6 months to ensure continued safe operation and only manufacturer’s original replacements should be used.

  • Page 73: High Pressure Hoses

    High Pressure Hoses Hose assemblies require careful handling to provide long service life and to guard against potentially dangerous failure. Serious injury and death can result from the failure of a hose assembly that is damaged, worn out, wrongly assembled or installed incorrectly. ...

  • Page 74: Pump Bleed Screws

    Pump Bleed Screws  Never open pump bleed screws when pump is running on high pressure. High pressure fluid will jet from the bleed screw hole and it could cause injury.

  • Page 75: Exhaust Gases & Fire Prevention

    Exhaust Gases & Fire Prevention Our jetters use diesel or petrol (gas) powered engines  Engine exhaust fumes can be very harmful if allowed to accumulate in enclosed areas. Only run the engine in a well-ventilated location.  The exhaust gas from the muffler is very hot. To prevent a fire do not expose dry grass, mowed grass, oil of any other combustible materials to exhaust gas.

  • Page 76: Freezing Conditions

    Freezing Conditions  If the equipment has been frozen, it is essential that the whole system is first thoroughly thawed, then cautiously flushed without any nozzle or other restriction attached to the high- pressure hose.  Ice Bullets – ice may be trapped in the system. No attempt should be made to force the ice out by starting the engine.

  • Page 77: Adequate Drainage (Wastewater)

    Adequate Drainage (Wastewater)  Ensure that there is adequate drainage of the jetted water. Large puddles should never be allowed to accumulate, particularly on suspended floors.  The weight of accumulated waste water can create a hazard. 1,000 litres of water weighs 1,000 kgs 300 gallons (US) of water weighs 2,500 lbs...

  • Page 78: Daily Checks

    Daily Checks To ensure the equipment is safe to use carry out all daily checks before you operate the jetter. These can include the following:  Water filter cleanliness  Fuel level  All jets are clean and free from debris ...

  • Page 79: Explosive Atmospheres

    Explosive Atmospheres Water jetting within enclosed areas that have not been gas-freed or inerted may create a risk of ignition of flammable vapour by an electrostatic charge generated by the action of the water jet.  Equipment used in explosive atmospheres must be certified to the correct ATEX level. Check before commencing work.

  • Page 80: Trailer Jetters

    Trailer Jetters  Always park the trailer on level ground  Always put the handbrake on or chock the wheels before removing from the towing vehicle  Never operate the hydraulic hose reel unless the trailer is hitched to the towing vehicle ...

  • Page 81: Jetting Applications And Accessories

    Jetting Applications and Accessories All our jetting accessories are designed to be safe in operation, but operators must be aware that misuse could cause serious injury. In the following sections we have noted hazards specific to the misuse or those arising from general use of various accessories.

  • Page 82: Drain & Pipe Cleaning

    Drain & Pipe Cleaning  When a jetter is used to clean drains & sewers that are contaminated with a hazardous substance it is possible these may be entrained in the resulting aerosol an inhaled by operators. Consider using respiratory protection. ...
  • Page 83  Never work in a manhole where explosive gases may be present with a radio remote control transmitter that is not designed for use in hazardous areas.  Never use the hydraulic hose reel facility as a winch to retract a jetting hose that has become stuck in the drain or pipe.

  • Page 84: Jetting Guns

    Jetting Guns  Never exceed the recommended maximum for reaction force (250N with shoulder stock & 150N without shoulder stock). Other national standards may apply. of the operator’s Current guidance in the USA is that reaction forces should not exceed 1/3 bodyweight for extended periods of time.
  • Page 85  Never use the jetting gun to clean a surface that could be damaged by the water jet.  Always ensure that an adequate area is cordoned off around the working zone so that flying debris and contamination cannot injure passers-by. ...

  • Page 86: Tube Cleaning

    Tube Cleaning  Manual tube cleaning is not recommended by Flowplant.  If our jetting units are used to power automatic & semi-automatic tube cleaning equipment specific safety instructions must be obtained from the tube cleaning equipment manufacturer prior to use.

  • Page 87: Floor Cleaners

    Floor Cleaners  Never adjust the operating pressure when the unit is running.  Never use the floor cleaner over uneven or damaged surfaces.  Never raise the floor cleaner from the floor when under pressure.  Over pressurising the floor cleaner could lead to it becoming dangerously unstable.

  • Page 88: Jet Pumps

    Jet Pumps  When using a Venturi jet pump never place your fingers into the pump inlet as they could be trapped by the vacuum and cause injury. Always secure the free end of the pump hose securely and ensure adequate drainage is in place to deal with high volumes of pumped water.

  • Page 89: Dry Shut Guns & Foot Valves (Additional To Jetting Guns Info)

    Dry Shut Guns & Foot Valves (Additional to Jetting Guns Info)  When using a dry shut type system, be aware that high pressure can be retained in the jetting hose even after the machine has been shut down. Always discharge pressure in a safe manner after machine shut down.

  • Page 90: Electric Machines

    Electric Machines  Flowplant electric machines operate at voltages of up to 690 volt and 200amps. Only trained, competent electricians should install units and carry out any maintenance works.  If working on any maintenance schedules related to the electrical installation, the electrical supply must be isolated.

  • Page 91: Hot Water Machines

     Only trained, competent operators to use Flowplant hot water machines.  Flowplant hot water machines will operate at temperatures over 90 degrees centigrade. Care must be taken to not come into contact with any of the operating fluids. ...
