Confined Spaces

DID YOU KNOW?

More than 30% of confined space fatalities occur when someone enters the space to rescue another worker. [1]

KNOW THE RISK

  • A confined space is any area with limited entry or exit and is not intended for continuous occupancy. These spaces can become deadly very quickly. [1]
  • Examples include tanks, silos, underground vaults, crawlspaces, storage bins, and manholes. [2]
  • Hazards in confined spaces include harmful gases, oxygen deficiency, engulfment, electrical hazards, or moving parts. [1]
  • Approximately 100 fatalities occur each year in the U.S. from confined space incidents — many during rescue attempts. [1]

MITIGATE THE RISK

1. Never Enter a Confined Space Without Proper Training and a Permit

  • Confined spaces should be entered only by trained personnel following OSHA permit-required procedures. Permits ensure hazards have been identified and controls are in place. [2]

2. Identify Hazards and Ventilate Before Entry

  • Test the atmosphere for toxic gases, flammable vapors, and oxygen levels. Use ventilation to bring the space to a safe condition. [2]

3. Maintain Constant Contact With an Attendant

  • A trained attendant must remain outside the space, maintaining communication and ready to summon help if needed. [2]

CONFINED SPACE REMINDER

Confined spaces are deceptively dangerous. Follow entry procedures, test for hazards, and never attempt a rescue unless you’re trained and equipped. The right precautions can save your life — and someone else’s.
