Washington — Fires and explosions from flammable atmospheres in confined spaces are the most common causes of hot work-related fatalities among workers, the Chemical Safety Board states in a recently released fact sheet.

Hot work is any activity that produces flames, sparks and/or heat. It is prevalent in numerous industries, including oil production, fuel storage, waste treatment, food processing, and pulp and paper manufacturing.

“These incidents often result in injuries and fatalities and have the potential to result in a major catastrophic incident,” CSB states.

The agency offers several best practices for staying safe when performing hot work:

  • Consider alternative methods, when possible.
  • Perform a hazard assessment before beginning work.
  • Monitor gas in the work area before and during operations.
  • Test the area and equipment before beginning work.
  • Ensure qualified personnel use written permits.
  • Train personnel thoroughly.
  • Supervise outside contractors performing hot work.
