What is a code-number?
The Danish MAL code system is a simple two-part numerical code system that describes a product's effects on health. Many of the Danish CatSub examples refer to code-numbers. A brief explanation of the codes is therefore given in CatSub.

Several product types must be code-numbered by the supplier:

Painter's products
Car paints and paint-like surface coatings, e.g. acrylate floors

Glue
Organic solvents used for bonding:
- in construction work
- in the car industry (e.g. bodywork) and aircraft parts

Filling material
Fillers, jointing compounds, stoppings and putty:
- in construction work
- in the car industry (e.g. bodywork) and aircraft parts

Graphic printing processes
Printing inks, serigraphy inks and other products.
Diluents used for the above products.
Products used for preparation and finishing when working with the above products, including degreasers, detergents and paint removers.

Further information
Read more about code-numbered products in Executive Order No. 302 of 13 May 1993 on work with code-numbered products, issued by the Danish Working Environment Authority.

Code-numbers and examples of products
The code-number indicates the minimum safety precautions that must be taken when using the product for specific work processes.

The higher the number, the greater the hazard!
Select products with as low numbers as possible

Risk due to inhalation The figure before the hyphen indicates the risk of inhaling vapours hazardous to health from the product, e.g. organic solvents, ammonia and acetic acid.		Risk due to contact with the skin, etc. The figure after the hyphen indicates the risk of health detriment due to contact with the skin, inhalation of spray clouds or ingestion.
