New Alert on Power Tool Electric Shock


An alert by NT WorkSafe, a division of the Department of Business in Australia, identifies electric shock hazards associated with excessive sweating during use of electricity-powered tools. The alert warns that power drills, grinders, welders and tech screw guns are the most common tools to cause electric shocks in hot, humid conditions.

To prevent or lessen electric shock, NT WorkSafe offers the following suggestions: 
  • Avoid use of tools powered by electricity during the hottest part of the day. Instead, try using battery-powered tools when possible.
  • Use residual current devices, which will limit electric shocks to a subcritical level.
  • Isolation transformers can also limit the risk of electric shock.
  • Voltage reduction devices and G clamp earths can be used in welding to reduce shock risks.
  • If a power tool has caused shocks, it should be isolated and tagged out, then examined by a trained individual to ensure that it is fit for use before retesting and tagging the tool.
