general control measures for Cable Laying and Pulling Operations

Cable laying and cable pulling operations should be controlled through a documented safe system of work that combines risk assessment, a task-specific method statement, competent supervision, and permit controls where required. The work should be planned to identify route conditions, cable type and weight, pulling tensions, plant and equipment needs, underground and overhead hazards, access constraints, environmental conditions, and interfaces with other work activities. A pre-start briefing should confirm roles, communication methods, exclusion zones, emergency arrangements, and stop-work criteria. Work should not begin until the route is surveyed, hazards are assessed, controls are in place, and all workers understand the sequence of work and the limits of their authority.

Key risk assessment and method statement controls should include:

• Define the scope of work, cable route, pulling direction, entry and exit points, joint bays, pits, trenches, ducts, and termination locations
• Assess ground conditions, weather, lighting, access/egress, nearby structures, public interface, and simultaneous operations
• Identify hazards from moving plant, winches, rollers, capstans, cable drums, suspended loads, stored energy, snap-back zones, and line-of-fire positions
• Determine cable weight, drum handling method, minimum bending radius, maximum pulling tension, sidewall bearing pressure, and lubrication requirements
• Specify manpower levels, supervision, competency requirements, banksman/signaller arrangements, and communication methods
• Include step-by-step controls for unloading drums, positioning jacks, setting rollers, pulling cable, jointing, testing, reinstatement, and housekeeping
• Define hold points for permit checks, service detection, excavation inspection, lifting plans, isolation confirmation, and authorization to energize
• Review residual risks and update the assessment if route conditions, equipment, or scope change

Permit to work requirements:

• Use a permit to work where the activity involves excavation, entry into confined or restricted spaces, work near live electrical systems, hot work, lifting operations in controlled areas, road occupation, or work on client-controlled infrastructure
• The permit should clearly state the exact location, scope, validity period, isolations, service drawings reviewed, precautions required, emergency contacts, and hand-back arrangements
• Permits should be supported by the risk assessment, method statement, utility clearance information, and where applicable electrical isolation or lockout/tagout documentation
• Suspend work and revalidate the permit if conditions change, the work extends beyond the authorized period, or new hazards are identified

Manual handling and cable drum handling:

• Avoid manual lifting of heavy cable, rollers, covers, trench boxes, or drum components where mechanical aids can be used
• Assess load weight, shape, grip, route, posture, team size, and frequency before any manual handling task
• Use drum jacks, spindle bars, forklifts, cranes, cable trailers, tuggers, and other suitable equipment operated by competent persons
• Store cable drums on firm level ground, chock them to prevent movement, and position them so they cannot roll unintentionally
• Never place hands or feet under suspended drums or between the cable and fixed objects during unreeling or pulling
• Use coordinated team lifts only for manageable loads and ensure clear commands, good footing, and unobstructed travel paths

Underground services identification and excavation safety:

• Obtain and review the latest utility drawings, as-built records, permits, and client information before breaking ground
• Carry out a service detection survey using appropriate locating equipment and mark identified services on the ground before excavation starts
• Use safe digging practices such as trial holes or vacuum excavation where service congestion or uncertainty exists
• Treat all detected or suspected services as live until positively identified and protected
• Do not use mechanical excavation within the defined tolerance zone of buried services unless specifically authorized and controlled
• Support trench sides where required by soil conditions, depth, surcharge loads, vibration, or water ingress risk
• Provide safe access and egress to excavations, keep spoil and materials away from edges, and prevent falls with barriers or covers
• Inspect excavations at the start of shift and after rain, vibration, impact, or any event that could affect stability
• Stop work immediately if unidentified services, contaminated ground, gas, flooding, or signs of collapse are found

Lifting operations and mechanical pulling equipment:

• Plan lifting operations for cable drums, winches, generators, trench boxes, and heavy accessories using suitable equipment with adequate capacity
• Ensure cranes, excavators used for lifting, forklifts, slings, shackles, and lifting beams are inspected, certified, and used within their rated limits
• Appoint competent operators, slingers, and signallers, and use a lifting plan for complex or high-risk lifts
• Establish exclusion zones around lifting and pulling operations and keep personnel out of suspended-load areas and snap-back zones
• Anchor winches and pulling equipment securely, verify pulling line alignment, and inspect ropes, grips, swivels, and rollers before use
• Never stand in line with a tensioned rope or cable, and control access to areas where recoil or sudden movement could occur
• Use guarding or barriers where practicable around rotating parts, nip points, and moving machinery

Electrical safety controls:

• Identify whether existing cables or adjacent systems are live, isolated, abandoned, or liable to become energized
• Use formal isolation, lockout/tagout, test-for-dead procedures, and authorization by competent electrical personnel before work on or near electrical conductors
• Maintain safe approach distances from live electrical equipment and overhead lines, taking account of tools, plant, cable lengths, and lifting equipment
• Use insulated tools and voltage-rated test equipment where required, and verify test instruments before and after proving dead
• Protect temporary power supplies, generators, and distribution boards with suitable earthing, RCD protection, weather protection, and cable management
• Do not energize newly laid cables until inspection, testing, termination checks, and authorization are complete
• Control induced voltage, backfeed, stored energy, and capacitor discharge risks where relevant to the system

PPE requirements should be based on the risk assessment and site rules, but typically include:

• Safety helmet
• High-visibility clothing suitable for the work environment
• Safety footwear with midsole and toe protection
• Gloves selected for handling, abrasion, cut resistance, or electrical work as appropriate
• Eye protection for cutting, drilling, blowing, pulling, or when debris may be generated
• Hearing protection where winches, generators, breakers, or traffic create excessive noise
• Task-specific PPE such as arc-rated clothing, dielectric gloves, respiratory protection, or fall protection where the assessed risk requires it

Traffic management and public protection:

• Prepare a traffic management plan where work affects roads, footpaths, plant routes, or public areas
• Use barriers, cones, signs, lighting, and segregated pedestrian routes to protect workers and the public
• Control vehicle movements with trained banksmen where visibility is restricted or reversing cannot be avoided
• Provide safe loading and unloading areas for cable drums and plant, away from live traffic where possible
• Maintain emergency access routes and do not obstruct hydrants, exits, or critical infrastructure
• Secure open trenches, pits, and stored materials at all times, including outside working hours

Safe work procedures during cable laying and pulling:

• Inspect the route, ducts, pits, rollers, pulling heads, swivels, lubricants, and communication devices before starting
• Confirm the cable drum orientation and pulling setup so the cable pays off smoothly without reverse bending or uncontrolled movement
• Position rollers and guides to prevent cable damage and to keep hands clear of pinch points
• Use agreed signals or radios between the winch operator, drum watch, and supervisors, with one person controlling the pull
• Pull at controlled speed and within the cable manufacturer's tension and bending limits
• Stop immediately if abnormal resistance, snagging, sheath damage, duct obstruction, equipment instability, or communication failure occurs
• Keep the work area tidy, remove trip hazards, manage waste, and maintain clear access around pits and trenches
• Cap or protect cable ends as needed to prevent moisture ingress or contamination
• After installation, secure the cable, complete inspections and testing, reinstate covers or trench protection, and leave the area safe

Emergency procedures:

• Establish emergency arrangements before work starts, including first aid, rescue from excavation or confined space if relevant, fire response, and contact numbers
• Brief workers on the location of first aid kits, fire extinguishers, spill kits, assembly points, and the method for summoning help
• If a buried electrical cable or gas service is struck, stop work, keep personnel clear, prevent ignition sources, and notify the responsible utility and emergency services as required
• In the event of electric shock, do not touch the casualty until the source is isolated or made safe; call emergency services and begin first aid/CPR if trained and safe to do so
• For trench collapse, do not attempt an uncontrolled rescue; secure the area and use trained rescue arrangements
• Report and investigate near misses, service strikes, equipment failures, and injuries before restarting work

Compliance should align with applicable HSE and regulatory requirements, client rules, utility owner requirements, and manufacturer instructions. In practice this means using competent persons, suitable and maintained work equipment, safe excavation controls, lifting planning, electrical isolation procedures, PPE selection, welfare arrangements, incident reporting, and supervision proportionate to the risk. Records should be maintained for risk assessments, briefings, permits, inspections, service detection, lifting equipment checks, training, and test results. If local law or project specifications impose stricter controls than the general measures above, the stricter requirement should be followed.
