Safety alert 09/2012 - Cutting or heating metal tanks

• The fuel tank may have previously contained a highly flammable liquid and possible chemical residue. 
• Angle grinders produce ignition sources such as heat and sparks. 
• There was no labelling on the tank to indicate the type of fuel that had been stored, nor information that it had been purged, cleaned and de-gassed appropriately.

• Do not use angle grinders or any other heat-producing equipment such as welders to cut metal tanks or drums that have or may have contained flammable or combustible liquids or flammable gases.
• Where there is any doubt about the previous contents of a tank or drum, have the contents tested for chemical makeup.
• Make sure tanks and drums are recycled by specialist cleaning companies.
• Have Material Safety Data Sheets (MSDS) available for all hazardous substances at the workplace and provide this information to all employees who are likely to be exposed to these substances.  
• Provide adequate training and instruction to ensure that employees understand the MSDS information, especially employees who have limited understanding of English. 
• Treat all tanks and drums as hazardous or having contained an explosive substance or vapour.
