TITLE:	ES&H Manual
DOCUMENT ID:	6200 Appendix T1 Electrical Safety Inspection Procedure

1.0 Purpose

Jefferson Lab uses this procedure to evaluate electrical equipment and installations to assure compliance with the requirements of Occupational Safety and Health Administration (OSHA) 29CFR1910.399 using National Recognized Testing Laboratory (NRTL) standards and the National Electrical Code (NEC).

OSHA 29CFR1910.399 – NRTL standards and the NEC state that all installations and equipment are acceptable for use only if approved by a NRTL or the Electrical Authority Having Jurisdiction (EAHJ).

Electrical equipment and installations at Jefferson Lab (acquired after the effective date of this procedure) require inspection if it meets even one of the following criteria:

· Non-NRTL commercial/industrial equipment ;

· NRTL commercial/industrial equipment that has been modified ;

· Custom built electrical equipment;

· Legacy equipment to which any serious or important modifications are made (Use the Graded Approach Procedure to determine modification degree);

· System owner request;

· Facility-type electrical installations not installed per the National Electrical Code (NFPA 70).

Electrical equipment which has passed inspection is labeled with a Jefferson Lab Approved Inspection Label:

Exceptions:

• An inspection is not required if the equipment is powered by a source less than 50 volts ac or 60 volts dc.
• A complete inspection is not required if by doing so voids the warranty of the equipment. In such a case a non-invasive inspection is performed and documented as “equipment under warranty.”

2.0 Scope

This document defines the minimum responsibilities and process steps used to ensure that electrical equipment and installation inspections comply with OSHA standards and Jefferson Lab requirements.

If electrical equipment is listed or labeled by an NRTL, no examinations or other actions are required unless the equipment is being used in a manner that is not consistent with its listing and labeling.

NOTE: Equipment and materials purchased or brought on site by users to support experiments are outside the scope of this chapter. ESH&Q controls for experiments are developed during the experimental review process. See ES&H Manual Chapter 3120 The CEBAF Experiment Review Process and ES&H Manual Chapter 3130 FEL Experiment Safety Review Process.

Equipment purchases accompanied by detailed specifications, a formal review process, and under the responsibility of a design authority are also outside the scope of this chapter; see ES&H Manual Chapter 3410 ES&H Aspects of Procurement.

3.0 Responsibilities

NOTE: Management authority may be delegated at the discretion of the responsible manager.

3.1 Equipment/System Owner

· Contact the Electrical Safety Engineer to request an electrical inspection.

· Submit any variance requests to the EAHJ.

3.2 Electrical Equipment Inspector (EEI)

· Determine the relevant codes and standards with which the equipment or installation to be inspected must comply.

· Ensure that electrical equipment designed and constructed, or procured, meets the intent of applicable electrical safety standards including the best practices outlined in ES&H Manual Chapter 6240 Electrical Equipment Construction and Maintenance.

· Perform Electrical Safety Inspections -- certifies that equipment or installations comply with relevant safety standards.

· Verify that inspected non-listed electrical equipment is free from reasonably foreseeable risk due to electrical hazards.

Minimum Qualifications:

o Seven years of accumulative training, education, or experience relevant to the electrical equipment design and installation standards for the type of system being evaluated.

3.3 Electrical Safety Engineer (ESE)

· Assign an appropriate inspector to perform the equipment/installation inspection.

· Approve the Electrical Safety Inspection determination.

· Maintain the Electrical Safety Inspection records.

· Affix the “Approved Inspection Label” to equipment that passed inspection.

· Ensure that approvals, variances determinations, and other issues are communicated to equipment/system owners.

· Maintain minimum EEI qualifications.

3.4 Electrical Safety Committee (ESC):

· Resolve any equipment or installation inspection disagreements.

· Make binding determinations regarding variance requests.

· Certify EEI status.

4.0 Process Steps

Electrical equipment and installation inspections use industry codes and standards as guidelines.

Commonly used codes and standards are:

· NFPA 70 (National Electrical Code)

· NFPA 70E (Standard for Electrical Safety in the Workplace)

· OSHA 29 CFR 1910

· OSHA 29 CFR 1926

· IEEE C2 NESC (National Electrical Safety Code)

· UL 508 (Industrial Control Equipment)

· NFPA 79 (Electrical Standard for Industrial Machinery)

· DOE – Electrical Safety Handbook

· ANSI/UL 61010 Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use.

· Jefferson Lab ES&H Manual Chapter 6240 Electronic Equipment Construction and Modification Safety.

4.1 Inspection – to be done before equipment is used or installed:

Step 1 - Use the ES&H Electrical Equipment Safety Inspection Checklist to list all conditions and assumptions that accompany the acceptance of the equipment or installation.

Step 2 - Perform a visual inspection using a Hazard Based Safety Approach (HBSA).

Step 3 - Perform or witness, as appropriate, a test that demonstrates the effective safety performance characteristics of the equipment (e.g. grounding, insulation, or leakage current).

Step 4 - Certify that the equipment or installation has been inspected and meets requirements.

Alternate Step 4 -

1. If the equipment or installation does not pass inspection use:

· ES&H Manual Chapter 6111 Appendix T1 Administrative Control using Locks and Tags Procedure.

2. Provide any recommended corrective actions to the equipment/installation owner.

3. Arrange for re-inspection of rejected equipment or installation if required.

Step 5 - Submit the original signed checklist (certified or rejected) to the ESE.

A HBSA evaluates the safety of electrical equipment and installations through a combination of construction requirements, installation specifications, and compliance with specific standards of the equipment or installation being reviewed. A HBSA inspection is the basis for deciding whether or not a piece of equipment or an installation will be hazardous in its intended use.

4.2 Approval – To be performed by ESE:

Step 1 - Indicate approval on the certified Electrical Safety Inspection Checklist.

The ESC resolves any disagreements between an equipment/installation owner and the EEI.

Step 2 - Contact System Owner regarding the status of equipment or installation.

Step 3 - Upon approval of the inspection checklist the ESE applies the “approved inspection” label to the equipment inspected.

Alternate Step 3 - Approved installations do not require an “approved inspection” label.

4.3 Documentation:

· Completed Electrical Equipment Safety Inspection Checklists are maintained by the ESE.

4.4 Variances:

· Requests for code and regulation variances are submitted to the EAHJ.

· The variance requirements are included in the Electrical Equipment Safety Inspection Checklist.

· The ESE ensures the decision is communicated to affected parties.
