Appendix T1 List of
Permit Required Confined Spaces |

|

Introduction
There are more than
100 spaces at Jefferson Lab which are considered to be permit-required
confined spaces (PRCSs) or must be treated as such until qualified staff
determine that there are no actual or potential hazards. A few of the PRCSs are
located inside buildings, and Jefferson Lab employees or subcontractors make
infrequent entry – typically for inspection or maintenance. The majority of PRCSs are
underground, are entered through manholes, and were built to protect and allow
access to a single utility, such as electrical power, communications systems,
and sanitary sewer. Entry into these
spaces is also infrequent and normally is made by representatives of the
utility or a Jefferson Science Associates, LLC (JSA) subcontractor.
Jefferson Lab’s
official list of PRCSs is
maintained as Jefferson Lab drawings 00-C-8-2142-001 and 00-C-8-2143-002
“Confined Space Locations.”
PRCSs are
listed in this appendix to illustrate their number, types, and locations at
Jefferson Lab. This list was current on
the date of issue of this document.

List of Permit-Required
Confined Spaces
Every PRCS is
assigned a unique alphanumeric designation.
The assignment of the designator is based on the following system:
|
Type of Space |
Designator |
|
Building
confined space |
B followed
by the building number, hyphen, and then consecutive numbers starting with 1 |
|
Communications
manholes |
EMHC
followed by consecutive numbers starting with 1 |
|
Electrical
power manholes |
EMH followed
by consecutive numbers starting with 1 |
|
Lift
station-sanitary sewer |
LS
followed by consecutive numbers starting with 1 |
|
Lift
station-storm water |
LW
followed by consecutive numbers starting with 1 |
|
Mechanical
manholes |
MMH followed
by consecutive numbers starting with 1 |
|
Sanitary
Sewer manholes |
SSMH
followed by consecutive numbers starting with 1 |
|
Water
Meter Vault |
W followed
by consecutive numbers starting with 1 |
|
Other
kinds of Vault |
V followed
by consecutive numbers starting with 1 |
|
Unverified
means precise location or hazard potential has not been fully verified by
Laboratory ESH&Q staff. |
