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 electrical equipment is covered under the APS Policy User Electrical Equipment Inspections.  For further information refer to the APS User Electronic and Electrical Equipment Inspection Criteria.

APS users are not allowed to perform electrical work.  Electrical work does not include work involving equipment where ALL of the following apply: (1) equipment used only in accordance with operating instructions AND/OR involves plugging/unplugging the equipment, 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 experiments in this hazard class are categorized as medium risk and require inspection and review by APS Designated Electrical Equipment Inspectors (DEEIs).  Details of these inspections can be found in the User Electronic and Electrical Inspection Criteria.

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 (DEEIs).

Training

  • Follow the guidance provided in the APS User Safety Update (February 16, 2005).
  • ESH408 - Electrical Safety Awareness is required for all APS employees/resident users (ESH408 is not required but is recommended for users).

Signs and Labeling – As determined by review.

Personal Protective Equipment – As 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 APS Experiment Safety Review Board and resident beamline personnel having the authority to authorize experiments as listed in the ESAF system.  Approval by both the host beamline and APS Experiment Safety Review Board are mandatory prerequisites for experiment authorization.

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, and ANL Designated Electrical Equipment Inspectors (DEEIs).
