| Live services: electricity (contact with live cables, fittings, distribution boards and containment while stripping out lights, sockets and ceiling services) | Operatives: electric shock, burns, fatality. Others in the unit if a fire is started. | Competent supervisor, CCDO carded operatives, 110V RCD-protected tools. | 3×5=15 | Service isolation permit and permit to work in place before any strip-out. Electrical supply isolated by a competent person, locked off and tagged, then proven dead with an approved voltage indicator (Electricity at Work Regulations 1989). Service drawings checked and cable routes marked. Any live circuit that has to stay on is marked, protected and kept out of the work area. Cut ends made safe and capped as they are exposed. Cable detection or visual tracing before cutting into walls or ceiling voids. Isolation rechecked at the start of every shift. Insulated hand tools and 110V supply only. Insulating gloves for any electrical handling as a back-up. | Medium |
| Live services: gas and water (striking or cutting pipework in walls, floors and ceiling voids; flooding; gas escape) | Operatives and anyone nearby: asphyxiation, fire or explosion, slips on water, damage to the unit and neighbouring units. | Permit to work, isolation permit, supervisor on site. | 2×5=10 | Gas and water isolated at the main and the pipework in the strip-out area identified using the service drawings and the PC. Gas pipes confirmed as capped or purged by a Gas Safe registered engineer before any cutting. Do not cut or break into any pipe unless it is confirmed isolated, drained and made safe. Know the location of the isolation valves. If a gas smell or leak is found, stop work, remove people from the building, do not use electrical switches or phones inside, and call the National Gas Emergency Service on 0800 111 999. Spill kit and wet vacuum for water leaks. Pipework cut with hand tools only after proving it is dead and drained. | Medium |
| Asbestos: disturbing suspected asbestos-containing materials (for example ceiling tiles, partition linings, boxing, lagging, floor tiles, textured coatings) in a unit where asbestos is likely to be present | Operatives and anyone nearby or entering the unit afterwards: inhaled asbestos fibres can cause mesothelioma, lung cancer and asbestosis, often decades later. | UKATA asbestos awareness training, face-fit tested operatives. | 3×5=15 | Check the client's asbestos register or management survey for the unit before work starts. For strip-out where the register does not cover the area, a refurbishment and demolition survey is needed before any work (Control of Asbestos Regulations 2012, Regulation 5). The permit is not issued until this is confirmed. Briefing on the stop-work rule: if suspect material is found, stop, keep people away, report it to the supervisor and the Principal Contractor, and do not carry on until it has been identified. Any asbestos found is dealt with by an appropriately licensed or competent contractor as the survey and regulations require. Operatives hold awareness training only and do not carry out any asbestos removal themselves. Do not break, drill or scrape unidentified material. Keep the exclusion zone and a clean access route. Disposable FFP3 RPE and coveralls available for an emergency stop-and-secure only. | Medium |
| Respirable crystalline silica (RCS) dust from breaking, cutting or drilling masonry, block, concrete, mortar, render or plaster partitions and fixings | Operatives doing the work and anyone nearby breathing the dust: silicosis, lung cancer, COPD and other long-term lung disease. | Dust extraction on site, face-fit tested operatives. | 4×4=16 | Plan the work to reduce cutting, breaking and drilling, for example by taking partitions out at joints and fixings where possible. On-tool extraction (M-class or H-class vacuum) or water suppression on every breaker, drill, chaser and saw used on masonry or concrete. Keep others out of the area, and clean up with an H-class or M-class vacuum, never dry sweeping or compressed air (COSHH Regulations 2002; HSE CIS36 Construction dust). The RCS workplace exposure limit of 0.1 mg/m3 (8-hour TWA) in HSE EH40/2005 applies. Limit the number of people and the time in the dust area. RPE with an assigned protection factor of at least 20 (FFP3 disposable or equivalent), face-fit tested and worn clean shaven, as the last line of defence. | Medium |
| General dust and fibres from ceiling tiles, insulation, plasterboard, old dust in the ceiling void and debris disturbed during strip-out | Operatives: irritation of eyes, nose, throat and skin, and breathing problems with repeated exposure. | Dust extraction, supervisor monitoring. | 4×3=12 | Remove tiles and linings carefully by hand rather than breaking them up. Damp down lightly where suitable and bag debris at source. Use extraction at the point of dust creation, and a vacuum rather than brushing. Keep the exclusion zone closed and limit time in dusty areas (COSHH Regulations 2002; HSE CIS36). FFP3 disposable RPE, goggles and gloves as back-up. | Low |
| Uncontrolled collapse of partitions, ceiling grid, boxing or fixtures during demolition (falling debris, structure stability) | Operatives: crush injuries, struck by falling material, fatality. Other people entering the area. | Walls to be confirmed non-load-bearing, CCDO carded operatives, supervision. | 3×5=15 | Written confirmation from the Principal Contractor's designer that the partitions are non-load-bearing before any demolition, and that nothing above or beside relies on them. Demolish top-down in small controlled sections following the sequence in this method statement (CDM 2015, Regulation 22 on preventing danger from demolition and dismantling). Never pull over or undermine a complete wall. Keep a fall zone clear and marked, and work on one section at a time. Stop and review if any unexpected structure, a steel or a defect is found. Hard hats and safety boots as back-up. | Medium |
| Working at height at low level: removing ceiling grids, tiles, lights and services from podium steps or stepladders | Operatives: falls of up to about 2 to 3 metres causing fractures and head injuries. People below from dropped items. | CCDO carded operatives, supervision. | 3×4=12 | Work from podium steps or a low-level platform, not stepladders or makeshift access, where reasonably practicable (Work at Height Regulations 2005). Check equipment before use and keep it on firm, level ground clear of debris. Take work down to ground level where possible rather than reaching. Keep the area below clear of other people while overhead work is under way. Do not overreach. Do not use ladders as a work platform for heavy items. Hard hats as back-up. | Low |
| Manual handling of debris, plasterboard sheets, stud and rubble, and pushing and loading wheeled skips | Operatives: back, shoulder and arm injuries, sprains, crush injuries to hands and feet. | Wheeled skips, 4 operatives, trained operatives. | 4×3=12 | Reduce load size by breaking material into smaller sections, use wheeled skips and trolleys, and two-person lifts for bulky or heavy items (Manual Handling Operations Regulations 1992). Keep the route to the skip level, clear and short. Rotate tasks and take breaks. Do not overfill wheeled skips. Gloves and safety boots as back-up. | Medium |
| Noise and hand-arm vibration from breakers, the reciprocating saw and other power tools | Operatives: hearing damage, tinnitus, hand-arm vibration syndrome, and others nearby affected by noise. | Rotation of operatives, RCD-protected 110V tools. | 4×3=12 | Use hand demolition methods where practical rather than breakers. Choose low-vibration, well-maintained tools and the right size of breaker for the job. Limit trigger time and rotate operatives across tasks. Keep the exclusion zone for noise and tell the Principal Contractor and neighbouring units when breaking starts. Control of Noise at Work Regulations 2005 and Control of Vibration at Work Regulations 2005 apply, with exposure times tracked by the supervisor. Hearing protection to the specification on the noise assessment, and anti-vibration gloves where suitable, as back-up. | Low |
| Cuts and puncture injuries from the reciprocating saw, sharp metal studs, track, nails, screws, broken glass and light fittings | Operatives: lacerations, eye injuries, puncture wounds. | Competent operatives, tools maintained, RCD-protected 110V supply. | 3×3=9 | Equipment inspected and used in line with PUWER 1998, with guards in place and the right blade for the material. Secure the work, keep hands clear of the blade path and cut away from the body. Bend over or remove protruding nails, screws and sharp edges as the wall is stripped. Put broken glass, tubes and sharps into a rigid container. Cut-resistant gloves, eye protection and safety boots as back-up. | Low |
| Slips, trips and falls on debris, cables, uneven floors, wet floors and trailing 110V leads | Operatives and anyone entering the unit: sprains, fractures, head injuries. | Protected routes to the skip, supervisor checks. | 4×2=8 | Housekeeping as the work progresses, with debris cleared to the skips at least every break and at the end of each shift. Keep leads off the floor on hooks or ramps and away from walkways. Keep the protected route to the skip clear and lit. Fix any area of wet floor and use adequate temporary lighting. Safety boots with slip-resistant soles as back-up. | Low |
| Fire: dust build-up, cutting sparks, combustible waste in skips, cable damage and an unfamiliar escape route | Operatives, other trades and neighbouring units: burns, smoke inhalation. | Permit to work, site cabin and canteen provided by the Principal Contractor. | 2×4=8 | No hot works planned. Any hot work needs a separate permit from the Principal Contractor. Keep combustible waste to a minimum and keep skips away from the building. Keep escape routes clear. Fit extinguishers close to the work area and carry out a briefing on the alarm and assembly point. Remove dust build-up regularly. Do not smoke in the unit. Fire-retardant coveralls are not normally needed. | Low |
| Vehicle movements and loading of skips: skip lorry delivery and collection, reversing and loading at the unit entrance and roller shutter, and the general trade park vehicle traffic | Operatives, trade park users and members of the public: being struck or run over, fatality. | Skips positioned by the Principal Contractor, protected routes to the skip. | 2×5=10 | Agree skip position, delivery and collection times and the vehicle route with the Principal Contractor before the start. Use a banksman to guide vehicles when a skip is delivered, loaded or collected. Segregate pedestrians from vehicles with barriers and cones. Keep the roller shutter area clear. High-visibility clothing as back-up. | Medium |
| Unauthorised entry and other people on site: Principal Contractor staff, other trades, neighbouring unit staff and visitors to the trade park entering the strip-out area | Other trades, neighbouring unit staff and visitors: exposure to dust and possible asbestos, falling debris, noise and tripping. | Unit is unoccupied, roller shutter and door, permit to work. | 3×4=12 | Keep the unit secured when unattended. Barrier and sign the exclusion zone and tell the Principal Contractor and neighbouring units when noisy and dusty work is under way. All visitors report to the supervisor and sign in. Only people on the permit are allowed in the strip-out area. Remove no barrier until the supervisor has signed the area off. Signs and barriers checked at the start of every shift. | Low |
