being made for locking the switch "off" and tagging it This precaution will prevent service interiuptions in the main circuit when power must he shut off in the branch circuit, and it will also prevent accidental starting of extra equipment that is tapped in Employee Training Few plants experience difficulty in selec tion and installation, but in maintenance and use of electrical equipment, deviation from safe practices is sometimes tolerated, with the usual result that unnecessary hazards are created and men are injured and killed Therefore, for maximum effectiveness, the safety program should include thorough training of all employees who work with the electrical installation of the plant or operate electrical equipment fn addition to instruc tions on the hazards of electricity, employees should be trained in first aid, the use of warning signs, guards, and other protective devices, and m safe operational procedures It is essential that they be trained in the mouth-to-mouth method of resuscitation and that distribution employees, especially, be trained in the pole-top method of resuscita tion The training program should consist not merely of generalization and indefinite rec ommendations, it should be based on the plant's electrical system and applied spe cifically to plant operations Supervisors should be given such instruc tions as may be necessary to acquaint them with the plant's electrical hazards, and they should be required to maintain close super vision over all operations which involve the use of electrical equipment They should en courage employees to report immediately any electrical defects observed and this equip ment should be repaired or replaced at once It is recommended that members of the plant safety department familiarize them selves with the codes and standards which apply to their equipment and operation and that someone from the electrical mainte nance staff be an active member of the plant safety committee The electrical mainte nance crew should consist of qualified elec tricians and other technically trained per sonnel according to the type of electrical equipment required in the plant References American Standards Institute, 1430 Broadway, New York, N Y 10018 Definitions and Ceneral Standards for Wire and Cables, C8 1 Dimensions of Caps, Plugs and Receptacles, C73 (Also N'EM ^ WD 1- 1965 ) Manual and Automatic Station Control, Supervisory and Associated Telemetering Equipment, C37 2 Relays and Relay Systems Associated with Electric Power Apparatus, C37 Requirements for Metallic and Associate Coverings for Insulated Cables C8 15 (Also IPCEA S-54-40I-I957 and NEMA WC2-1958 ) Safety Rules for the Operation of Electric Equipment and Lines C2 4 (Also NBS Hand book H34-I938 ' Specifications for Rubber Insulating Tape C59 6 (Also ASTM Dl 19 ) Specifications for Weather-Resistant Wire and Cable (URC Type ) C8 18 Specifications for Rubber Protective Equipment for Electrical Workers J6 Dalziel, Chailes F Effect of Electric Current on Man " Electrical Engineering, Febmarv 1941 ` Scientific Facts Concerning Electrical Hazards '' National Safety News, October 1947 "Electricity --Good and Faithful Servant '' National Safety News, September 1961 MeElrov, Frank E "Check Up on Your Electrical Outlets ' Cathohc Building and Mainte nance 15 92-98 (July-August 1963) 1007
