Code Number - Paints and Cleaners

Paints and cleaners used in painting must be marked with a code number

The code number consists of two figures connected by a hyphen. The code number indicates what safety precautions should be taken when using a product, including the personal protection and technical measures such as ventilation to be used. So code numbers can help give an overview when you are choosing products.

The figure before the hyphen indicates the safety precautions to be taken to avoid breathing in vapours.

The figure after the hyphen indicates the safety precautions to be taken to prevent skin/eye contact and to prevent ingestion, such as by smoking or eating without previously washing hands. Safety measures are also aimed at giving protection against direct contact with spray mist.

The law states that code numbers must also give the year. Code numbers derive from Ministerial orders and the year shows when legislation came into force. The last was issued in 1997.
Seahealth has a code numbered schedule giving guidance on the regulations for code-numbered paints - the previos issued by the Danish Maritime Authority is still valid. It is designed to be hung up in the paint shop.

For indoor painting, use the product selection schedule which also provides information on the general effects of water-based paint and practical requirements. Ventilation must also be provided if so stated in the schedule. Page 2 shows the personal protection and special workwear required when using different types of paint and in different work situations. The rules are given in Danish Maritime Authority Notices A Ch. II B.

The code-numbered schedule can be downloaded here.


As stated in the legislation, when choosing or switching products, opt for a product with the lowest code number if there are no technical or financial reasons for choosing another.

In the case of two-component products, use the code number for the mixture.

If two products have the same code number, obtain more details to find out which product is the least harmful. That is to say, R(isk) sentences and data about the substances in the product.
