The two types of confined spaces are a permit-required confined space and a non-permit required confined space. A permit-required confined space is a a space with the following characteristics:
- Large enough for an employee to enter and perform work
- Has limited or restricted means for entry and exit
- Is not designed for continuous employee occupancy
- Plus one or more of the following characteristics:
- Contains, or has the potential to contain a hazardous atmosphere
- Contains material with the potential to engulf the entrant
- Has an internal configuration that may trap, disorient, or asphyxiate an entrant by changing wall configurations or smaller cross sections
- Contains any other recognized safety or health hazard.
A non-permit required confined space is a confined space that does not contain, or have the potential to contain atmospheric hazards or any other hazards capable of causing death or serious physical harm. An example of a non-permit required confined space is an open top pit.
