Painting and decorating on construction sites involves working at height, handling solvent-based products, sanding surfaces that may contain lead paint or asbestos, and repetitive overhead work causing musculoskeletal strain. Enclosed spaces with poor ventilation concentrate solvent vapours to harmful levels. Correct access equipment, adequate ventilation, and appropriate PPE are essential. Painters must also be aware of the specific hazards when working in occupied buildings where residents and the public are present.
Key Hazards
Solvent vapour inhalation in enclosed spaces causing dizziness and respiratory harm
Falls from ladders, stepladders, and trestle platforms during overhead application
Exposure to lead paint dust when sanding or preparing previously painted surfaces
Repetitive strain injuries from sustained overhead painting and rolling work
Control Measures
Ensure adequate ventilation when using solvent-based paints, varnishes, and stains in enclosed areas.
Use the correct access equipment for the work height and duration rather than overreaching from ladders.
Check for lead paint on pre-1970s surfaces before sanding and follow the lead removal procedure if found.
Wear RPE when sanding, spraying, or applying products that generate harmful dust or vapour.
Take regular breaks from overhead work to prevent neck, shoulder, and arm strain.
Store paint, solvents, and thinners in the designated COSHH cupboard away from heat and ignition sources.
Read the safety data sheet for every product before use and follow the PPE recommendations.
Protect floor surfaces and adjacent areas from spills using dust sheets and masking.
Dispose of solvent-contaminated rags in a closed metal container to prevent spontaneous combustion.
Remember
Solvent vapours accumulate rapidly in enclosed spaces and can cause unconsciousness at high levels.
Use proper access equipment for all overhead painting — overreaching from ladders causes falls.
Lead paint is present in many buildings built before 1970 and must be identified before sanding.
Solvent-soaked rags can spontaneously combust and must be stored in closed metal containers.
Read the safety data sheet for every product because hazards vary significantly between products.
Overhead painting causes cumulative strain injuries so regular position changes and breaks are essential.
