Walls may have very shallow foundations which can be undermined by even reducing small levelsDecide if the structure needs temporary support before digging beginsSite Specific risk assessment must address soil conditions, depth, services, work to be done, contamination, overburden and length of time the reduce dig will be open.Spoil to be positioned and stacked at least 1.5m from the edge of the reduce level dig. Inspect the open areas daily or before each shift (weekly record findings if applicable)Persons falling in and around reduce level digApplicablexNot Applicable326111Protect the public and workers by installing barriers around the working area and ensure the necessary lights, signs and barriers are maintained when the planned works begins.

Consider destabilising forces and use effective measures to prevent overturning where required. Consideration is given to:-the strength of the ground on which the lifting equipment is locateduses of plates to support the weight of equipmentstability of the surface under load conditions, ie. when close to an excavation.whether equipment is on a slope and the angle of the slopethe size and nature of the loadhow the load is to be lifted and the maximum wind loading that may occurAppropriate measures must be established to prevent lifting equipment from tilting, overturning of where appropriate moving or slipping. Lifting equipment should not be used to drag loads if liable to overload or damage equipment.Rates capacity indicators or limiters may be required where significant hazards exist. Appropriate measure should be taken to prevent a freely suspended load from moving in an uncontrolled manner.Guide ropes must only be used to position a load. Failure to inspect, Defective equipment / Failure to examine and test lifting equipmentApplicablexNot Applicable326212Only lifting equipment which has been thoroughly examined and tested by a competent person must be used. The frequency of examination, testing and record keeping should be in accordance with LOLER 98.Where lifting equipment is used in arduous environments it should be inspected prior to use and at regular intervals by staff that are trained and competent to do so.Lifting equipment must be stored in conditions that do not lead to damage of deterioration.Inspections to be recorded and kept until next inspection.Only equipment and tackle with appropriate test certificates which have been examined prior to use must be used. Lifting equipment should be selected which is suitable for the conditions under which it will be used.Lifting equipment which has been identified as defective, by examination, test or inspection must not be used and must be taken out of service.Locating Underground Cables / Potential Contact with Underground ServicesApplicablexNot Applicable339224Poor quality and not updated service drawingsProbability of unknownsResidual riskObtain drawings and other information from Utilities, Telecom etc before work starts where possible try to obtain coloured drawings. Consult utilities with a view to isolating any service if possible. Ensure all appropriate PPE is worn to carry out the relevant tasks Personnel are to be trained, assessed as competent and familiar in the operation of cable/plant locators. Carry out CAT scan of area to identify location of existing services utilising all possible modes i.e. Power, Radio & Genny etc. Ensure use of Genny i.e. connect onto streetlight columns, valve boxes etcTake into consideration above ground furniture to help locate services i.e. streetlight columns, valve boxes, reinstated trenches etcMaintain calibration records of detection equipment.Confirm location of underground services via hand digging techniques prior to use of mechanical excavatorsMark layout with high visibility markers – especially cables on surface, extending beyond the area of work. Cables should be isolated if practicableUse ‘blunt’ digging tools i.e. round nose shovels or soil pick. Utilise CAT every 200mm while digging downDo not dig directly above service and expose from the sideMechanical plant/equipment & power tools must not be used within 500mm of a cable and LP/MP gas mains and services. Always work with extreme care as plant/cables can be found at any depthOverhead Services / Contact with Overhead Cables or PipeworkApplicablexNot Applicable339212Lifting operations in the vicinity of overheads should be avoided where possible where this cannot be avoided consideration should be given to protecting pliance with GS6 Guidance document when working within close proximity to overhead servicesIf you are unsure stop work and contact your line manager before beginning workWorking in a Confined SpaceApplicableNot Applicablex339212The competent person must be responsible for producing a safe system and briefing to all persons involved in the project if an concrete pour in an excavation is deemed a confined spaceTools and EquipmentIncorrect FittingVibrationEjection of particlesRuptureProlonged use of Vibrating EquipmentSlip, Trips and FallsApplicablexNot Applicable326111All equipment should be checked prior to use and any defects and damage reported; Periodic inspections, maintenance and certification to be carried out on equipment and details recorded as required; Only approved equipment may be used when working;Hire of equipment and plant should be checked to ensure it meets safety standards;Leaks should be reported and the spillage contained and cleaned up;Defective equipment should be immediately returned for maintenance and repairAll guards and safety devices must be in place before use and fit for purpose;Ensure all guards are maintained and correctly fastened to the tool; Use correct tool for the job when connecting any guards, discs etcDust suppression techniques must be used at all times when cutting paving stones, kerbs, brickwork etc. Ensure that no vehicles or personnel including members of the public are in the area which could be fit by flying debris and cause damageWhen using equipment ensure it is in good working order and regularly serviced.
