Confined Space Entry

3% of Non-roadway Fatalities*

Confined spaces typically have limited or restricted means of entry or exit and are not designed for continuous occupation by workers. Some confined spaces may contain hazardous or oxygen-deprived atmospheres. A few examples of confined spaces are tanks, vessels, silos, storage bins, vaults, tunnels or pipelines.**

Survey Says: The NSC 2020 Safety Technology in the Workplace Survey shows: 30% of workers surveyed reported being exposed to a confined space entry, and 13% report a confined space entry has caused or contributed to a serious workplace injury. 

The information in each section below is listed in the order of relevance to the hazardous situation.

Situational risks – inherent to the situation or proximate cause of injury
  • Oxygen deprivation – gases
  • Oxygen deprivation – material
  • Trench collapse
  • Explosions
  • Fires
  • Drowning
Systemic risks – contribute to injury but are not direct causes
  • Leadership failure
  • Lack of workplace awareness
  • Lack of training
  • Improper PPE
