Section 27-23. Protection against fire hazards in connection with rock work

In all places where workplaces are designed, constructed, fitted out and used, put into operation or maintained, suitable measures shall be taken to prevent the outbreak and spread of fire. Measures shall be taken so that any outbreak of fire can be stopped quickly and effectively.

The number of combustible materials that are kept underground shall be limited to what is absolutely necessary.

When it is necessary to use hydraulic fluids, such use shall, as far as possible, be limited to fluids that are not easily ignitable to avoid the risk of fire and the spread of fire. The hydraulic fluids must satisfy specifications and test conditions relating to fire resistance and hygiene criteria.

If hydraulic fluids are used that are not in accordance with such specifications, conditions and criteria, further precautions shall be taken to avoid increasing the risk of fire and spread of fire.
