Bodyshops may have paint thinners, gun-cleaning solvents, primers, coatings, degreasers and waste liquids close to electrical tools and vehicle preparation areas. A solvent spill is therefore more than a slip hazard: flammable vapours and ignition sources can make an otherwise small release dangerous.

Find the transfer and cleaning hotspots

Review paint mixing, spray-gun cleaning, solvent storage, waste containers, parts preparation and the routes used to move tins between them. Damaged lids, decanting and poor housekeeping are frequent opportunities for leaks. Keep containers secured and compatible spill containment where liquids are transferred.

Never rely on open buckets or absorbent rolls as a permanent way of dealing with solvent loss. Ventilation, correctly selected electrical equipment, ignition control and workplace design are part of the primary risk controls.

Use an assessed response, not a generic kit

For a small, identified and safely manageable non-reactive liquid release, compatible chemical absorbents or absorbents may be suitable. Fuel or oil leaks elsewhere in a workshop may call for oil-only absorbents. However, flammable solvent spills require decisions based on the DSEAR assessment, including the possibility of vapour accumulation and ignition.

If vapour levels or ignition risks are uncertain, clear the area and call trained responders. Do not operate ordinary electrical cleaning equipment or fans in a potentially flammable atmosphere unless assessed as suitable. Follow the safety data sheet and site emergency procedure.

Keep contaminated waste and stock controlled

  • Segregate solvent-soaked absorbents and waste containers from general rubbish.
  • Store flammable waste in appropriate containers and approved locations.
  • Keep spill stations and routes to exits unobstructed.
  • Record leaks from pumps, cabinets and washing equipment.
  • Train new staff on reporting and emergency isolation.

The HSE provides COSHH advice for motor vehicle repair and HSE guidance on DSEAR. Use both when designing bodyshop spill controls.
