Electrical Safety Puzzle

Across

3. Electrically connected to or having a source of voltage.
5. Electrical Equipment. Equipment that is not or has not been left fully intact or assembled, and if turned on, will create an electrical hazard to personnel.
6. Any voltage check, which is performed after the initial voltage verification, to ensure there has been no change in electrical status to the equipment since the equipment was last worked on.
11. Personnel that have not been trained in this policy or in the safe operation, repair, or maintenance of equipment. Any individual who is not qualified, per section 230.4.B.1, is a nonqualified person.
12. A dangerous condition associated with the possible release of energy caused by an electric arc.
13. A general term, including material, fittings, devices, appliances, fixtures, apparatus, and the like, used as a part of or in connection with an electrical connection that will utilize electrical energy.
17. Work being performed on or within electrical enclosures or equipment not placed in an Electrically Safe Working Condition (ESWC). The performance of energized work is regulated through the paragraphs of section 230.4.D.
18. Unintentional or unplanned contact by tools or personnel with energized conductors or circuit parts.
20. Sometimes shortened to shock: the physiological reaction, characterized by pain and muscular spasm, to the passage of an electric current through the body. It can affect the respiratory system and heart rhythm.
21. A physical obstruction (e.g., tapes, cones, or by location) to provide a warning about, and limit access to, a hazardous area. These items are installed temporarily while the work is ongoing.
22. The value attributed to materials that describe their performance to exposure to an electrical arc discharge. The arc rating is expressed in
23. An approach limit at a distance from an exposed energized electrical conductor or circuit part within which a shock hazard exists.
25. Any object that can transmit electrical energy.
27. A state in which the conductor or circuit part to be worked on or near has been disconnected from energized parts, isolated per reference 230.3.B and/or OSHE Control Manual, Chapter 250 (Hazardous Energy Control) and verified by initial voltage verification (IVV) to ensure the absence of voltage, and grounded, if determined to be necessary.
28. An approach limit at a distance from an exposed energized electrical conductor or circuit part within which there is an increased risk of shock, due to electrical arc-over combined with inadvertent movement, for personnel working in close proximity to the energized electrical conductor or circuit part.
29. Voltage present in an otherwise isolated circuit, which is not the result of a direct connection to an energized source. Other common terms used to describe stray voltage include: induced voltage, ghost voltage, and phantom voltage.

Down

1. A person that has been trained in this policy and is familiar with the safe operation, repair, and maintenance of the equipment and the hazards involved. A person can be considered qualified on certain pieces of equipment or circumstances, but not others. An employee who is undergoing on-the-job training and who, in the course of such training, has demonstrated an ability to perform duties safely at his or her level of training and who is under the direct supervision of a qualified person is considered to be a qualified person for the performance of those duties.
2. Approach limit at a distance from a prospective arc source within which a person could receive a second degree burn if an electrical arc flash were to occur.
4. A unit used to measure incident energy is calories per centimeter squared (cal/cm2)
7. for Qualified Personnel. The distance from any energized exposed electrical conductor or circuit part that personnel and conductive objects must remain without using Electrical Safety Equipment (ESE). The electrical approach distances for shore facilities and shipboard are identified by boundaries in Appendix B.
8. A non-conductive physical obstruction (with insulating capability for the voltages involved) that is intended to prevent contact, either directly or inadvertently, with equipment or exposed energized components. Examples of materials include rubber sheeting, matting, or other suitable insulating materials to protect or shield personnel from exposed electrical shock hazards. DO NOT USE insulated soles as an alternative to rubber insulated mats.
9. Specifically designed and designated surfaces for electrical insulation (e.g., insulating and electrical rubber products, insulated electrical tools/work benches), provided the surfaces remain clean, dry and undamaged (i.e., free of oil, grease, liquids, etc.).
10. The voltage check performed after equipment or system isolation to verify the absence of voltage.
14. A circuit disconnected from all sources of voltage and free from any stored energy like Capacitors.
15. Nonconductive equipment to protect personnel from electrical shock and/or injury while performing work on a component and/or system that is not in an Electrically Safe Work Condition (e.g., insulating blankets, approved matting, approved gloves, and certified tools).
16. Any work performed on a circuit for which an Electrically Safe Work Condition has been established.
19. busses, terminals, or conductive metal objects that are uninsulated or are capable of being inadvertently touched so that a shock hazard exists for personnel.
24. Defined as (a) testing, (b) calibrating, (c) taking measurements, (d) troubleshooting, (e) repairing, (f) assembling, (g) disassembling, (h) making adjustments, and (i) maintenance.
26. A general term including parts of the electrical or electronic equipment.
