IC 7453 Underground Metal-Mine Fires from Cutting and Weldipg

Underground fires often prove difficult to control , and a small fire can quickly grow into a large one , endangering life and causing large property damage . Even a small underground fire may produce enough noxious gases to cause suffocation ; therefore , every precaution should be taken to prevent and control such fires . It is ironic that mine fires should be caused when utilizing materials that are in themselves fire - resistant ; yet , cutting and welding of iron and steel are proving to be common causes of underground fires in metal mines . This paper includes 19 examples of underground fires of this nature , and undoubtedly this is only a fraction of the number of similar fires that have occurred in the last few years . This paper will review some metal - mine fires caused by cutting or welding and point out precautions to be taken to prevent other fires from this cause .
