According to LKAB, today's regulations on smoke and chemical diving are too detailed, which in turn they think leads to ineffective rescue efforts in the event of fires in mines and rock facilities.

The company believes that the international regulations used in other countries are more adapted and safer. Therefore, it has been examined whether it is possible to make an exception to the Swedish rules.

Double no

The mining giant first turned to the Swedish Work Environment Authority, which made the following assessment.

"Very good reasons are required for exceptions, such as that it is impossible to comply with a rule, or that a technological development has rendered a rule obsolete. The fact that other countries have different rules does not mean that there are automatically conditions for the Swedish Work Environment Authority to grant exemptions from the regulations," they write in the decision.

The decision was appealed to the Administrative Court, but they make the same assessment. SVT has spoken to LKAB, which declines to comment.
