Experiment Hazard Class 12 – Electrical and Electronic Equipment

Applicability

This hazard classification applies to all experiments involving electrical and electronic equipment. Other hazard classifications and their associated hazard controls may also apply to experiments in this hazard class. The inspection of electric equipment is covered under the APS Policy For User Electric Equipment Inspections.

Electrical hazards does not include work involving equipment where ALL of the following apply: (1) equipment use only in accordance with operating instructions AND/OR involves just plugging/unplugging, AND; (2) The equipment is either NRTL-listed or displays an Argonne barcoded ELECTRICAL SAFETY APPROVED sticker, AND; (3) The work involves no attempts to remove covers or panels that might expose energized electrical components.

It should be noted that unless required Argonne training has been completed, APS users are not allowed to perform electrical work.  Electrical hazards (does not include work involving utilization equipment where ALL of the following apply: (1) equipment use only in accordance with operating instructions AND/OR involves just plugging/unplugging, AND; (2) The equipment is either NRTL-listed or displays an Argonne barcoded ELECTRICAL SAFETY APPROVED sticker, AND; (3) The work involves no attempts to remove covers or panels that might expose energized electrical components.)

Experiment Category

All Hazard Class 12 experiments are categorized as medium risk experiments and require inspection and review by APS Designated Electrical Equipment Inspectors. Please read the details of these inspections.

Experiment Hazard Control Verification Statements

Engineered Controls – Determined by review and results of a DEEI inspection of the equipment.

Procedural Controls – Determined by review and results of a DEEI inspection of the equipment.

Design Reviews and Equipment Inspections – Review and mandatory inspection of equipment by ANL Designated Electrical Equipment Inspectors.

Training – Follow the guidance provided in the APS User Safety Update (February 16, 2005) and APS User Safety Update (April 12, 2006).

  • ESH377 - Electrical Safety Awareness is required for all employees and users regardless of job function.
  • ESH371 - Electrical Safety Training – General (web based training) is required before any work on electrical equipment can be performed. Such work includes inserting and removing cards from computer internals, cutting and splicing wires, soldering wire connections and components, terminating cables, and other activities where good electrical safety practices are necessary. Users must have completed this course to be considered "qualified" by Argonne to perform electrical work. Additional details and clarifications will be provided at a later date.
  • ESH114 - Lockout/Tagout
  • ESH375 - NFPA 70E
  • Work at < 50 V requires ESH377, ESH371, and ESH114
  • Work at > 50 V requires ESH377, ESH371, ESH375, and ESH114.

Signs and – Determined by review.

Personal Protective Equipment – Determined by review.

Experiment Authorization

Unless otherwise noted in the approved experiment safety plan, the PSC Deputy Associate Laboratory Director of Operations delegates the authority to authorize an experiment in this hazard class to a member of the AES Experiment Safety Review Board and resident beamline personnel appearing in the Deputy's list of personnel having the authority to authorize experiments.

Hazard Control Verification

The PSC Deputy Associate Laboratory Director of Operations delegates responsibility for verifying that required controls are in place to the experiment On-site Spokesperson, Beamline Management personnel having experiment safety responsibilities, and ANL Designated Electrical Equipment Inspectors.
