**[General Requirements and Advance Notification]{.underline}**

The Contractor Entry Supervisor (also known as the Supervisor
Authorizing Entry) is responsible for the following:

-   Providing advance notification of the confined space entry activity
    to SNL On Duty Incident Commander (IC) **PHONE: 844-4189 (24-hour
    duty phone)** to verify that rescue services are available. Advance
    notification must occur by phone on a daily basis for the duration
    of the entry activity. If additional written information is
    requested by the SNL/IC, it may be faxed to 844-7474 (preferred) or
    844-6533. **NOTE:** Do not fax entry notification, phone contact
    must be established with the IC prior to work.

-   Ensuring that the means for summoning emergency response/rescue
    personnel is operable and readily available.

-   Notifying the IC when the entry activity is terminated. As with
    notification, termination must occur on a daily basis for the
    duration of the activity.

-   Selecting the retrieval equipment and determining if the use of the
    equipment would increase the overall risk of entry and would not
    contribute to the rescue.

-   Identify alternate means for the Rescue Service to contact the Entry
    Supervisor (cellular, pager, radio, etc.) in the event emergency
    services become unavailable during the entry period.

-   Ensuring all equipment and instrumentation is inspected prior to use
    to ensure proper working condition. Equipment shall be maintained in
    accordance with manufacturer\'s requirements.

-   Posting the entry permit at the entry site.

-   If chemical materials are used in the confined space, the
    manufacturer\'s Material Safety Data Sheet (MSDS) must be attached
    to the permit.

**[Non-Entry Extraction of Confined Space Entrant(s)]{.underline}**

Should it become necessary to extract personnel from a confined space,
it is essential that all personnel involved know exactly what to do and
what not to do. There have been several instances where persons who were
trying to rescue an individual in a confined space also became victims,
because of failure to follow the proper procedures. The Attendant may
retrieve a victim wearing a retrieval line from a confined space if this
is possible without additional help **and does not require entry by the
Attendant.** Typical retrieval/extraction equipment includes tripod,
wincher (mechanical lifting device), retrieval line, and body harness.
Retrieval equipment is not required for Non-Permit Confined Spaces;
however, strong consideration should be given to spaces which present
unique rescue difficulty due to location (such as remote areas), space
configuration, or other elements.

The hazards associated with work in confined spaces include possible
exposure to the following:

1.  Oxygen deficient atmospheres (Less than 19.5%)

2.  Oxygen enriched atmospheres (Greater than 23.5%)

3.  Atmospheres containing flammable gas or dust

4.  Atmospheres containing toxic substances or biological hazards

5.  Mechanical or physical hazards

-   **The On-Duty Incident Commander prefers SNL personnel contact them
    7 days/24 hours first. If necessary, the IC will contact Kirtland
    Air Forces Base. SECONDARY: Contact: Kirtland Air Force Base**
    (service after standard hours and weekends) **PHONE: 846-8069;**
    FAX: **846-6569.** Also notify the SNL/IC.

NOTE: In Technical Areas or \"limited access\" areas where the use of
cellular phones is prohibited, communication radios suitable for
contacting emergency response services, are available from the
Construction Inspection and Acceptance Group. Instructions for radio use
are also available from the Construction Group.
