Application precautions
Paints and varnishes sold for DIY use are generally safe. Solvent-based materials may be classified as Flammable under the Chemicals, Hazard Information and Packaging for Supply Regulations (CHIP). As such, precautions should be taken to prevent sources of ignition from being in the vicinity of such coatings. The container lid should be replaced whenever possible. Particular attention should be paid if the material is being sprayed as this may generate a flammable atmosphere, which is extremely hazardous due to the unprotected nature of domestic electrical switches and appliances.

It is not recommended that a solvent-based coating be applied to large areas such as walls or floors unless suitable precautions are taken. If this is necessary, the area should be adequately ventilated and appropriate respiratory protective equipment for protection against vapours should be worn. A paper dust mask is not adequate.

It should be noted that white spirit, a solvent commonly found in solvent-based paints and varnishes has been assigned an Occupational Exposure Standard (OES). As such, use of this material at work will be within scope of the Control of Substances Hazardous to Health Regulations.

Further guidance is given in two information papers from the Building Research Establishment:

BRE Information Paper IP 3/92: Solvent vapour hazards during painting with white-spirit-borne eggshell paints.

BRE Information Paper IP 8/95: Interior painting of trim with solvent-borne paints.

These are available from the publishers – CRC Ltd, 151 Rosebery Avenue, London EC1R 4GB, Tel 0171 505 6622, fax 0171 505 6602.

Asthmatics may be sensitive to the vapours from solvent and water-based coatings.

Some paints available to professional painters may be classified hazardous to health by the CHIP Regulations. This will be indicated by a symbol in an orange/yellow box and certain Risk Phrases given in the health and safety information section of the container label ..

It is important that paint is only obtained from reputable sources. Materials sourced elsewhere e.g. car boot fairs may not be suitable for DIY use.
