Requirements:
General (5.1)

Penetration Permit

Penetration work will require a permit, subject to the conditions below. (See Penetration Safety: Permit Form [pdf].)

Class 1 Penetrations

A penetration permit is required for Class 1 penetrations unless the activity and subsequent hazard analysis and controls are documented in a routine or non-routine JHAM.1

All penetrations within a radiologically controlled area (RCA), a radioactive material management area (RMMA), or part of accelerator shielding (for example, the Accelerator Housing Structure, End Station A Hall, Klystron Gallery Floor) require a penetration permit.

Note: If a responsible line manager or designee has direct knowledge that a structure, wall, floor, or other surface does not contain electrical, gas, or other hazards, and this structure, wall, or floor is not part of or within an RCA, RMMA, or accelerator shielding, then these requirements do not apply and a Class 1 penetration may be authorized without a hazard evaluation or documentation

Class 2 Penetrations

A penetration permit is required for all Class 2 penetrations. The activity and subsequent hazard analysis and controls shall be documented on the permit, unless they have already been documented in a routine or non-routine JHAM, in which case the permit will reference that documentation.

Pre-job Briefing

The responsible line manager/designee will conduct a pre-job briefing, in accordance with work control or safe work practices, prior to performing any work that requires penetrations. The briefing will cover the hazards and controls associated with the work and the correct use and care of PPE required to perform the work safely.

Stopping Work

If any unexpected conditions are encountered while performing a penetration, the operation must be stopped and the responsible line manager must be informed. Examples of unexpected conditions are unexpected or unusually slow drilling or cutting, overheating and/or rapid dulling of drill bits or saw blades, metal shavings where drywall is expected. (See Chapter 2, "Work Authorization".)

In addition, work must be stopped if any of the following conditions occur before or during the penetration:

• Penetration area boundaries change.
• Additional penetration work beyond the scope of the original work is required.
• Site conditions change that affect the location of the penetration or interfere with the penetration in some way.

Structure and Equipment Specific

Penetrations into specialized structures, such as radiological shielding or hazardous material confinement structures, may require review and approval by other organizations. For example, Radiation Protection Department approval is required for all penetrations into radiological shielding structures.

Recordkeeping

• Penetration permits and non-routine JHAMs for penetration operations will be available at the job site.
• Penetration permits and non-routine JHAMs that are part of a facility work package or programmatic work will be maintained in accordance with the requirements of that facility.
