Purchasing guidelines

If you have questions on confined space equipment please check with EHS prior to purchase.


    • What is a Confined Space? A confined space must meet these 3 requirements.
      • The space is large enough and so configured that an employee can bodily enter and perform assigned work;
      • Has limited or restricted means for entry or exit (for example, tanks, vessels, silos, storage bins, hoppers, vaults); and
      • Is not designed for continuous employee occupancy.

    • What is a permit required Confined space?

      A permit-required confined space has one or more of the following characteristics:

      1. Contains or has the potential to contain a hazardous atmosphere;
      2. Contains a material that has the potential for engulfing an entrant;
      3. Has an internal configuration such that an entrant could be trapped or asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a smaller cross-section; or
      4. Contains any other recognized serious safety or health hazard.
      *If the space meets ANY of the four criteria, then the space has a “high hazard potential” and is a permit-required confined space. A permit system must be implemented according to Cal/OSHA regulations*

    1. Before the employee is first assigned to perform or participate in confined space entry;
    2. Before the employee is expected to perform duties during confined space operations for which the employee has not previously been trained; and
    3. When it is determined that an employee has insufficient knowledge or skills to perform assigned duties.
