  METHOD STATEMENT
  DOCUMENT REF LPCMS01 – BUTTFUSION WORKS
  DESCRIPTION OF WORKS – TO BE READ IN CONJUNCTION WITH THE APPROPRIATE RISK ASSESSMENT Buttfusion is method of joining mdpe / hdpe pipework without using electrofusion couplers. The pipework is fitted into a chassis with the appropriately sized shells used to clamp the pipe in a solid position. The ends are then trimmed and squared off using a trimmer plate. Once the ends have been trimmed a hot plate is used to gently heat the pipework to the correct temperature and then the two ends are forced together under pressure and a bead is formed. The process is fully automated but does rely on the operator to insert the correct operating parameters into the equipment. This process is completed inside a dry, dust free environment which is usually a pop-up tent or shelter. The pipework is supported by rollers which hold the pipe level with the Buttfusion chassis and reduces drag. Test joints will be performed at the start of each working day or when required by the client. The equipment data logs all joints that have been completed and this data is then downloaded and forwarded onto the client.

• LPCMS02 ELECTROFUSION

  Required

  Not required

• METHOD STATEMENT
  DOCUMENT REF LPCMS02 – ELECTROFUSION WORKS
  DESCRIPTION OF WORKS – TO BE READ IN CONJUNCTION WITH THE APPROPRIATE RISK ASSESSMENT Electro fusion is a way of joining two hdpe / mdpe pipes together using a premade socket. The socket is made of mdpe and has a wire element inside with is connected to two pins which is connected an electrofusion box. The electrofusion box then heats the element which in turn gently warms the pipework so that it fuses together. There are two different voltages used for electro fusion (40v and 80v) so you need to make sure that you are using the correct fitting with the correct electro fusion box. Each fitting has a pre marked fusion time stamped upon it which needs to be uploaded to the equipment. Some modern electrofusion boxes have an auto read function which automatically reads the fusion time.

  HAZARDS • Hydrogen sulphide (H2S) is a very toxic, and extremely flammable and potentially explosive gas.
  • H2S is also an extremely malodorous substance, which can be detected by the Human nose in the parts per billion ranges.
  • Any work to be carried out on Landfill Gas and Leachate installations where it is known high H2S concentrations exist must be Risk Assessed for its potential impact on the environment and local resident/s nuisance and appropriate controls put in place.
  • The Workplace Exposure Limits for H2S are:
  15 minute short term exposure 10ppm
  8 hour time weighted average 5ppm
  At levels above 500 – 700ppm H2S causes rapid unconsciousness and death.

  • Death in severe cases
  • Note: Filter type respiratory protection is NOT effective against H2S and appropriate BA must be used if exposure is above 10 ppm. The Operatives must be fully trained in the use of BA Equipment.
  • If the concentration of H2S in landfill gas from any well or area of a landfill site is known, or suspected, to be in excess of 50ppm the following precautions are to be instigated immediately.
  • It is the responsibility of the Site Manager / client to ensure that all relevant contractors are informed that H2S in concentrations in excess of 50ppm have been monitored on site.
  • A plan and register must be kept on site of all areas and wells / chambers affected. This map and register must be referred to prior to any drilling or general works being undertaken.
  • In order that all areas and wells/chambers are clearly visible to all site users they may be marked on the site ‘DSEAR Zoning Plan’ by the Site Manger / client.
  • H2S warning signs must be placed on all wells / chambers with concentrations above 50ppm.
  • Implementation of a ‘Permit to Work’ protocol for all works that are to be undertaken on H2S wells / chambers should be arranged with the client.
  • All LPC personnel including sub-contractors working on site must wear a calibrated and fully charged personal gas alarm (ATEX Approved) which has had its trigger levels set to 5ppm and 10ppm.
  • It is the responsibility of the LPC team leader and client to ensure that all persons conducting work on gas or leachate systems must have completed a full site induction, which is to include the relevant H2S procedure and made aware of the results of any survey prior to conducting work.
  • When working (removal of pumps, extending of infrastructure etc) on wells, chambers, pipelines or similar which are identified as having high concentrations of H2S (greater than 50ppm), the following control measures are to be implemented. Wells which have not been monitored to contain H2S but in a 30 metre radius of a ‘H2S well’ must be treated as a ‘H2S well’.
  • Prior to any works taking place H2S monitoring of the well and area must be undertaken to determine the level of the gas concentrations.
  • Wherever possible works on infrastructure which have, or are suspected to have higher than normal levels of H2S must, wherever possible be carried out upwind of the infrastructure.
  • At all times during the works a suitable personal gas alarm (ATEX approved) with trigger levels set to 5ppm and 10ppm. Must be worn by at least one operator. This, where ever possible will be the operator who is working closest to the item of infrastructure.
  • Upon the alarm sounding on a personal H2S alarm (i.e. indicating that the 10ppm limit is being exceeded) all personnel must retreat 10m up wind of must be reported as a near-miss through the incident reporting system. Personnel must move at least 10m away upwind of the infrastructure/area.
  • All alarm soundings on personal H2S alarms must be treated as a near miss and as such reported to the Site Manager.
  • Operatives must remain 10m upwind of the infrastructure/area until the levels of H2S have dissipated or and until the personal H2S alarm has ceased to sound.
  • Once the personal H2S alarm has ceased to sound and prior to re-entering the area and the re-commencement of works, the area must be monitored using suitable gas monitoring equipment.
  • If the concentrations of H2S within the landfill gas are found to be below 5ppm, works can re-commence immediately. But the concentrations of H2S must be monitored continuously and the area evacuated to a distance of at least 10m upon the sounding of an alarm.
  • If the concentrations are found to be in excess of 5ppm, the client must be informed immediately.
  • Measures must be taken to adequately seal the infrastructure, whilst ensuring that no operatives spend greater than 10minutes in the area.
  • Works may only re-commence on the infrastructure by operatives who are wearing and are suitably trained and competent in the use of BA Equipment.

• METHOD STATEMENT
  DOCUMENT REF LPCMS21 – decommissioning redundant gas wells
  DESCRIPTION OF WORKS – TO BE READ IN CONJUNCTION WITH THE APPROPRIATE RISK ASSESSMENTS Decommissioning redundant gas wells is completed by excavating round the redundant well carefully so as not to damage the site capping liner. Different types of soils are kept separate during the process so they can be replaced upon completion of the operation. Once the well is excavated a suitable lifting strop is placed around the neck of the well and attached via a lifting hook and shackle to the excavator and the well is lifted /eased out of the ground. Banksman and other persons are to stand a suitable safe distance away during this process. The well is placed on the ground ready to be removed to a disposal point. The open void is then backfilled with the appropriate materials as specified by the client, this is usually a mix of gravel, sand and bentonite slurry. Upon completion of the works a wooden steak is placed to mark the location of the location.

  TASK PROCESS NOTES
  • Identify task to be completed – discuss exact requirements of the client before commencing any works.
  • Goto working location and assess the work to be completed – do you have the right equipment to complete the task?
  • If cutting small diameter pipe (25mm – 90mm) then use the pipe cutters supplied by LPC.
  • If cutting pipe sized between 90mm – 200mm then use the guillotine supplied by LPC.
  • If cutting larger diameter pipe, then use of a hand saw will be required. Make sure that the saw is in good working order and that the hand grip is free from oils and debris. Mark pipe using a marker pen at the location it is to be cut. Begin cutting in forward and back motions taking care to keep all body parts away from the blade.
  • You may need to use a suitable lifting device to support the weight of larger pipes.
  • Once cutting is complete clear away any off cuts and dispose of in the correct location.
  • If using a jigsaw make sure that it is 110v and in good working order and the pipework is free from any gases.
  • Drill a small hole in the pipework at the location required to start the cut.
  • Insert jigsaw blade into hole and proceed to cut.
  • Rotate pipework as cutting so a neat tidy cut can be make. Use lifting device for moving / carrying larger tools
