78 • THE FENCER'S ALMANAC 2015 GEOGRAPHICAL INDEX OF SUPPLIERS The normal wear and tear on electrical extension cords and fl exible cords at a job site can loosen or expose wires, creating hazardous conditions. Cords that are not 3-wire type, not designed cords that are 3-wire type. – Use only extension cords that are marked with a designation code for hard or extra-hard usage. – Use only cords, con- nection devices, and fi ttings that are equipped with strain relief. – Remove cords from re- ceptacles by pulling on the plugs, not the cords. – Continually audit cords on-site. Any cords found not to be marked for hard or ex- tra-hard use, or which have been modifi ed, must be taken out of service immediately. Examples of misused equipment – Using multi-receptacle boxes designed to be mount- ed by fi tting them with a pow- er cord and placing them on the fl oor. – Fabricating extension cords with Romex ® wire. – Using equipment out- doors that is labeled for use only in dry, indoor locations. – Attaching ungrounded, two-prong adapter plugs to three-prong cords and tools. – Using circuit breakers or fuses with the wrong rating for over-current protection, e.g. using a 30-amp breaker in a system with 15- or 20- amp receptacles. Protection is lost because it will not trip when the system's load has been exceeded. – Using modifi ed cords or tools, e.g., removing ground prongs, face plates, insula- tion, etc. – Using cords or tools with worn insulation or ex- posed wires. Damaged extension cord leaves arc welder ungrounded A 29-year-old welder at- tempted to connect a porta- ble arc welder to an electri- cal outlet using an extension cord. The power switch on the welder was already in the "on" position, and the female end of the extension cord, which was spring loaded, had apparently been dropped and broken. As a result, the ground prong of the welder plug did not insert into the ground ter- minal of the cord, so that as soon as a connection was made, the outside metal case of the welder became ener- gized, electrocuting the vic- tim. An examination revealed that the spring, cover plate, and part of the melamine casing were missing from the face of the female con- nector (the spring and some melamine fragments were found at the accident site). The victim was totally deaf in one ear and suffered diminished hearing in the other. He may have dropped the extension cord at the site and not heard the connector break. for hard-usage, or that have been modifi ed increase your risk of contacting electrical current. How do I avoid hazards? – Use factory-assembled cord sets. – Use only extension Focus on jobsite electrical safety COURTESY OCCUPATIONAL SAFETY & HEALTH ADMINISTRATION Visit Logical Decisions at www.LDI.com Your Gate Operator Specialist Find us on VISIT OUR WEB SITE OR CALL FOR MORE INFORMATION www.eprivacylink.com 1.800.574.1076 Hablamos Español Ten company policies our customers rave about: 1.
