Types of Confined Spaces


 

IMPORTANT!

All confined space entries shall be prepared and performed in accordance with the FSS PPS 04.05.01 Confined Space Entry.

A confined space is any enclosed area with the following characteristics:

  • Limited means of entry or exit
  • Structure that is not designed for extended human occupation
  • Atmosphere that is actually or potentially hazardous
  • Potential for other hazards

Because confined spaces offer limited means of entry or exit and may contain hazards, employees must comply with OSHA 29 CFR 1910.146 and the Texas State University Confined Space Entry Program when working in these areas. The Confined Space Entry Program is available from the Facilities Department.

Most confined spaces are actually or potentially hazardous. These confined spaces require work permits because they have one or more of the following:

  • Hazardous atmosphere or the potential to contain hazardous atmosphere
  • Materials that could engulf workers
  • Internal structure or contents that could trap or asphyxiate employees
  • Other recognizable hazards

Examples of confined spaces include the following:

  • Manholes
  • Crawl spaces
  • Tunnels
  • Tanks
  • Trenches
