What is a Permit Space?
In addition to the 3 requirements defining a confined space, a permit space is a confined space that also has one or more of the following 4 characteristics:
- Atmospheric Hazard: It has - or could have - a hazardous atmosphere.
- Engulfment Hazard: It contains material that could trap or bury a person.
- Configuration Hazard: It is shaped so that a person could become trapped or asphyxiated.
- Other Hazard: It has other safety or health hazards that could harm a person.
Most accidents in permit spaces happen when workers and untrained rescuers do not recognize hazards in the spaces or they do not control the hazards before they enter. Never assume a permit space is safe to enter. Permit spaces can have two types of hazards: hazardous atmospheres and physical hazards.
To help identify the spaces on a worksite, see this sample checklist.
