||Records of 311 fires involving welding or similar processes and 111 records of a fire brigade were studied to determine the detailed causes of the fires. Approximately 50% of the fires were started by flying sparks from welding, flame cutting or soldering. Ignoring fire protection rules and false ideas about the distances at which sparks are still capable of igniting fires were contributing factors. Experimental determinations of the range and surface temperatures of sparks showed that sparks from flame cutting had temperatures of 1600° to 1700°C at distances of 4m and more. Sparks could fly 10-15m.
