The Marine Corps is required to have a confined space entry program (non-maritime). Numerous confined spaces can be found aboard Marine Corps installations or units. Examples of such spaces include storage tanks, pits, boilers, portable water tanks (including bulls), fuel cells, ditches, sewers, utility vaults, tunnels, and manholes. The following characteristics define a confined space:
- Not designed for routine human occupancy
- Large enough for bodily entry
- Has restricted access or exit
If there is a doubt of whether a location is a confined space or not, please contact this office at phone number
