| Fall from height from the mobile access tower while plastering ceilings and upper walls | Both operatives: serious or fatal injuries from a fall. Anyone below: struck by a falling person. | PASMA trained operatives. Tower built to manufacturer's instructions with guardrails, toe boards and outriggers where required. | 3×5=15 | Avoid work at height where possible by using the lowest practicable platform and finishing as much as possible from the floor. Check ground and floor are firm and level, brakes on, and wheels locked before every use. Complete and record a tower inspection before first use and after any alteration (Work at Height Regulations 2005). Tower tag displayed. No moving the tower with people or materials on board. No overreaching and no standing on guardrails or using ladders from the platform. Use the internal stairs and landing edges only with the edge protected, and keep the tower away from stairwell openings. Hard hats not needed unless overhead hazards are present. Non-slip footwear as the last line of defence. | Medium |
| Fall from hop-ups when plastering walls and the lower ceiling areas | Both operatives: sprains, fractures and head injuries from falling off a low platform. | Hop-ups inspected before use and placed on level floor. | 3×3=9 | Choose hop-ups of suitable height and size for the task, with a non-slip platform. Clear the floor of buckets, leads and spilt plaster before each move. Position the hop-up so that no reaching is needed, and move it rather than stretch (Work at Height Regulations 2005). No standing on buckets, boxes or the edges of the hop-up. Do not use the hop-up on stairs or landings. Non-slip footwear as backup. | Medium |
| Occupied domestic site: Mr & Mrs Ashworth, their family, visitors, children and pets entering the work area, and other trades if booked | Occupants and visitors, especially children and pets: slips, trips, contact with wet plaster, dust inhalation, contact with the tower, mixer or leads. Operatives: disturbance and interruption. | Work area sheeted and cordoned off. Main entrance and stairs used as the route. | 3×3=9 | Agree with the clients at the pre-start briefing which rooms are out of bounds and who will be at home. Install a physical barrier and signage at door openings and keep the room doors closed or sealed. Keep the cordon in place for the full job and do not leave open buckets, tools or plant in unsupervised areas. Never leave the mixer or transformer plugged in when unattended. Keep bags and materials inside the cordon and out of reach of children and pets. Check the cordon at every break and at the end of each shift. Tell the clients which areas have wet plaster. Protect the stair route with floor protection. Keep the operatives' own PPE at hand but do not rely on it for the household, who are protected by segregation. | Low |
| Respirable crystalline silica (RCS) dust from any cutting back, scraping, drilling or fixing into existing brick, block, concrete or plaster during preparation, and from dry cleaning | The two operatives doing the work and the occupants and anyone nearby breathing the dust: long-term lung disease including silicosis, lung cancer and COPD. | Rooms sheeted and cordoned. Rooms ventilated. | 3×4=12 | Plan the work to reduce cutting back, scraping and drilling to the minimum needed. Use on-tool extraction (M-class or H-class vacuum) or water suppression on every drill, chaser or saw used on these materials. Keep others out of the rooms and clean up with an H-class or M-class vacuum or damp wiping, never dry sweeping or compressed air. Then use RPE with an assigned protection factor of at least 20 (FFP3 disposable or equivalent), face-fit tested and worn clean shaven. Comply with the Control of Substances Hazardous to Health Regulations (COSHH) 2002 and HSE Construction Information Sheet CIS36 'Construction dust'. The workplace exposure limit for RCS is 0.1 mg/m3 (8-hour TWA) in HSE EH40/2005. | Medium |
| General plaster dust from emptying bags and mixing, and from rubbing down, spreading to the rest of the occupied house | Operatives and household occupants: irritation to eyes, nose and throat, and aggravation of asthma or breathing conditions. | Rooms sheeted and cordoned. | 4×2=8 | Choose low-dust bagged products where available and open and tip bags slowly and low into the water. Mix in a contained, ventilated area with a lid or splash guard on the bucket. Seal the room doors and open the windows to the outside. Damp wipe or vacuum with an M-class or H-class vacuum, never dry sweep (COSHH 2002). Keep the household out of the mixing area. RPE as specified in the Safety Data Sheet, for example an FFP3 or FFP2 disposable, as a backup. | Low |
| Skin and eye contact with wet plaster, bonding coat and PVA, including splashes when working overhead on ceilings | Operatives: irritant or alkaline skin burns, dermatitis and eye injury. Anyone below the work: splashes. | Clean water available for washing. Operatives trained. | 4×3=12 | Use products with the lowest hazard rating where possible. Mix carefully with a splash guard on the bucket, and use a hawk and trowel techniques that limit dripping. Keep the area below the ceiling work clear. Provide clean water and an eye wash bottle at the work point. Wash hands and skin at breaks and at the end of the shift, and use barrier cream. Check skin for early signs of dermatitis weekly and report any soreness (COSHH 2002). Wear gloves, long sleeves and safety glasses or goggles to the standard in the Safety Data Sheet (for example BS EN 374 and BS EN 166) as the last line of defence. | Medium |
| Electric shock or fire from the 110V transformer, leads and electric paddle mixer used in wet conditions in a domestic setting | Operatives and household occupants: electric shock, burns or fire. | 110V supply through a transformer. Equipment checked before use. | 2×5=10 | Use only 110V equipment with a transformer, sited off wet floors and away from water. Visually inspect all leads, plugs and the mixer before use and use only items with a current PAT test label (Electricity at Work Regulations 1989 and PUWER 1998). Keep leads off the floor and clear of the mixing area and walking route. Do not use damaged equipment, and take it out of service at once. Isolate and unplug the mixer when cleaning or when unattended. Use a residual current device on the 230V supply feeding the transformer. Do not drill or cut into walls where cables or pipes may be hidden without checking with a cable and pipe detector. Rubber boots or insulating footwear if the floor is wet, as backup. | Medium |
| Manual handling of 25 kg bags of plaster, buckets of mixed plaster, the paddle mixer and tower components, including carrying up internal stairs | Both operatives: back, shoulder and arm injuries, and trips with loads. | Two operatives available. Stair route cleared. | 4×3=12 | Reduce the load by buying smaller bags where available, and mix in smaller batches. Store bags at the work area before work starts, delivering only what is needed for the day. Use a trolley or a carry by two for heavy bags, and carry one bag at a time on the stairs. Do not carry loads that block the view of the steps. Plan and rotate tasks to include rest breaks (Manual Handling Operations Regulations 1992). Gloves and safety boots (BS EN ISO 20345) as backup. | Medium |
| Slips, trips and falls from wet plaster, water, sheeting, leads and stairs in the work area and on the access route | Operatives and occupants: sprains, fractures and bruising. | Floor sheeted. Route from main entrance and stairs marked. | 4×3=12 | Use non-slip, taped-down floor protection. Keep the floor and stair route clear of leads, buckets and waste, and tidy as the work goes on. Mop and wipe up spilt plaster and water straight away, and use warning signs on wet floors. Route leads overhead or along walls rather than across the floor. Keep the cordon so the household is not on the route. Good lighting in the rooms and on the stairs. Non-slip safety footwear as backup. | Medium |
| Noise and hand-arm vibration from the electric paddle mixer and hand tools | The operative mixing: temporary hearing loss from noise, and hand-arm vibration over time. | Mixing in short batches. Equipment in good condition. | 3×2=6 | Use a well-maintained mixer with a lid or guard and keep mixing times short. Mix in an area away from the occupants and use a cut-off so that noise is limited to batches. Share the mixing between both operatives. Take breaks, and report numb or tingling hands (Control of Noise at Work Regulations 2005 and PUWER 1998). Hearing protection to BS EN 352 if the noise is intrusive, as backup. | Low |
| Disturbing unidentified asbestos-containing materials in existing walls, ceilings or coatings in a house of unconfirmed age while preparing the surfaces | Operatives, the household and anyone nearby: inhalation of asbestos fibres leading to serious lung disease, including mesothelioma and lung cancer, years later. | None until the check is completed. | 2×5=10 | Before work starts, S. Whitaker checks the client's asbestos register or management survey for both rooms. Where the register does not cover the area, a refurbishment survey of the area is needed before any work that disturbs the fabric (Control of Asbestos Regulations 2012, Regulation 5). Brief both operatives on the stop-work rule: if suspect material is found, stop, keep people away and report it to S. Whitaker and the client before work carries on. No drilling, scraping or removal of existing coatings or boards until cleared. This is a check to be made and does not mean asbestos is present. Report any damage to suspect material found. | Medium |
| Falling tools, materials and plaster from the tower and hop-ups onto people below | The other operative and anyone entering the room: head and body injuries from falling items. | Cordon around the work area. | 3×4=12 | Keep the area beneath the tower clear while work is going on and keep the household out. Use a tower platform with toe boards and keep tools in a bucket or pouch. Do not leave loose items on the platform and pass tools up and down by hand or on a rope, not by throwing. Keep the platform tidy and do not overload it. Warn others in the room before moving the tower or lowering items. Hard hats if work above others cannot be avoided, as backup. | Low |
| Awkward posture, repeated overhead reaching and neck strain when skimming ceilings | Both operatives: shoulder, neck and back strain and fatigue, which also raises the risk of falls and mistakes. | Two operatives so tasks can be shared. | 4×2=8 | Set the tower height so the work is at a comfortable level and avoid working with arms fully raised for long. Rotate the tasks between ceilings and walls, and plan regular rest breaks. Use good lighting to cut the need to lean. Report pain or strain early to the supervisor (Manual Handling Operations Regulations 1992). Safety glasses to keep wet plaster out of the eyes as backup. | Low |
| Fire and blocked escape in an occupied house, including sheeting and cordons across the escape route and smoke alarms covered or disabled | Operatives, Mr & Mrs Ashworth, their family and visitors: smoke inhalation, burns and delayed escape. | Main entrance available as the escape route. Smoke alarms in the house. | 2×5=10 | Agree the escape route and fire assembly point with the clients at the pre-start walk. Keep the cordon, sheeting, bags and the tower clear of the escape route and fire doors. Do not cover or disable any smoke alarms. If dust sheeting covers an alarm, agree an alternative with the clients and remove the sheeting at the end of every shift. Keep waste packaging and sheeting out of the work area and removed from site, and keep a fire extinguisher or similar to hand. Unplug equipment at the end of the day. | Medium |
