  1. Identifying, Assessing, and Inventorying 

    The first step in Confined Space safety at Apple is to identifying possible confined spaces requiring entry. This is effort is coordinated by the area owner and EHS to get a qualified determination.

    Next, a qualified person needs to assess the potential hazards and risks associated with entry of identified confined space. Those spaces are listed and maintained by EHS to create a Confined Space Inventory. Any space deemed a confined space will have signage and labelling indicating the hazard and warnings.

  2. Classifications

    Confined Spaces have 2 classifications:

    • Non-permit required confined space
    • Permit-required confined space

    A Non-permit required confined space is a location that does not contain or, with respect to atmospheric hazards, have the potential to contain any hazard capable of causing death or serious physical harm which could prevent the entrant’s ability to self-rescue

    A Permit-required confined space (permit space): A confined space that has ONE or more of the following characteristics:

    • Contains or has a potential to contain a hazardous atmosphere
    • Contains a material that has the potential for engulfing an entrant
    • 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
    • Contains any other recognized serious safety or health hazard

    These classification are important to understand because the personnel who are able to enter permit required confined spaces are only qualified contractors. Apple personnel can enter non-permit required confined spaces as long as the proper controls are in place.

  3. Entry

    Entry into a non-permit required confined space can be performed by two or more Apple employees using the buddy-system, entry procedures and controls like personal protective equipment.

    Entry into permit required confined spaces must be permitted. A permit requires three working days advanced notice to review, assess, control and approve. A permit must be obtained before entry into a permit required confined space can be made.

  4. Re-classification

    A permit-required confined space that has no potential for a hazardous atmosphere but whose non- atmospheric hazards can be isolated and eliminated, it may be possible to “reclassify” it temporarily as non-permit space for purposes of entry. Some permit-required confined spaces (such as cooling towers and air handlers which are entered regularly for maintenance and inspection) may be temporarily reclassified as non-permit spaces as long as all hazards have been identified and isolated/eliminated prior to entry. Normally this can be achieved through the effective application of the approved lockout-tagout procedure for the equipment.

  5. Training

    Hazard Awareness is a shortened training class focusing on the dangers of confined space entry intended for select employees. Confined Space Awareness Training (EHS-3700) is required for the following Apple employees:

    • Project Managers
    • MaOPS/Facilities employees who host contractors who will conduct permit-required confined space entries
    • Emergency Response personnel (ERT, MERT, and Apple Security)

    All employees who enter non-permit spaces Training is required:

    • Before the employee is assigned duties in a non-permit space
    • Before a host allows a contractor to make a permit-required confined space entry
    • When the manager or supervisor believes that there are deviations from the procedures discussed in this program or that there are deficiencies in employee knowledge or use of these procedures

    Contact site EHS to arrange the above confined space awareness training, or access it online through the EHS Training portal.
