Company hot work practices are described in the hot work supervision plan.
Hot work permits are always granted for a fixed period and for a certain hot work site. The permit gives the right to perform only the hot work specified in the permit.
Both the issuer of the hot work permit and the hot work operator must have a valid hot work licence. Hot work guards must have applicable safety training, and a valid hot work licence is recommended.
The hot work licence is valid for five years after completing training, and entitles the operator to do hot work in all the Nordic countries.
