Confined spaces may contain atmospheric or physical hazards that can quickly and unpredictably incapacitate an individual. Rescue efforts can be hampered by the hazards and configuration of the space, and unauthorized rescuers can become victims.
Some possible confined spaces at WSU include: grain silos, utility vaults, boilers, sewage pumps, lift stations, air plenums and ducts, pits, and sanitary manholes.
When employees have to enter a confined space meeting the following conditions, it requires them to be covered by WSU’s Permit Required Confined Space Program:

- Has hazardous condition(s)
- Potential or known hazardous atmospheres (such as low oxygen levels; air contaminants)

Contact Occupational Health & Safety (335-3041) to evaluate potential confined spaces prior to entry.
Employees are required to be authorized to enter a permit required confined space by attending training. Contact Occupational Health & Safety to schedule training.
