Plasterer & Dry Liner Compliance — Fire Stopping, Dust & Site Rules

Plasterers and dry liners carry out the internal finishing work that transforms a building shell into usable space. While the work may appear lower-risk than structural trades, plasterers and dry liners face specific compliance requirements around fire stopping, dust control, and manual handling that must be documented and managed.

Fire stopping is the most critical compliance area for dry liners. Plasterboard partitions, ceilings, and encasements often form part of the building's fire compartmentation — the system of fire-resistant barriers that prevents fire from spreading between compartments. Where services (pipes, cables, ducts) penetrate fire-rated partitions, the penetrations must be fire-stopped using tested and certified products. Every fire stop must be installed to the manufacturer's instructions and recorded. The Building Safety Act 2022 has strengthened the requirements for fire stopping records, particularly in higher-risk buildings.

Silica dust is a significant occupational health hazard for plasterers. Cutting and sanding plasterboard and cement-based renders generates respirable crystalline silica (RCS) dust, which causes silicosis — an irreversible and potentially fatal lung disease. The Workplace Exposure Limit for RCS is 0.1 mg/m³. COSHH records must cover silica exposure, and wet cutting methods or dust extraction must be used wherever practicable. HSE has made silica dust enforcement a strategic priority in construction.

Manual handling is another key compliance area. Standard plasterboard sheets (2400mm x 1200mm) weigh approximately 22-30 kg depending on type and thickness. Handling these sheets repeatedly, particularly on stairwells and in restricted spaces, carries a high risk of musculoskeletal injury. Manual handling risk documentation must be in place, and mechanical handling aids should be used where possible.

The Finishing & Interior Association (FIA) represents dry lining and plastering contractors. On site, plasterers need CSCS cards, RAMS, insurance, and evidence of fire stopping competence for any fire-rated work.
