Train all qualified workers, which may include heating, ventilation, and air conditioning (HVAC); maintenance; electricians; test technicians; and design engineers. If changing the color is not an option for you, adding company logos to the front or shoulder of uniforms can help give your team that professional look. The requirements are similar to other management system standards such as CSA Z1000, ISO 45001 and ANSI Z10.0, but with a specific focus on electrical hazards. Other tools that every electrical worker should have include insulated hand tools, insulated fuse pullers, a portable ground fault circuit interrupter (GFCI) cord or pigtail for cord and plug tools, rubber barrier material, and an Underwriters Laboratory (UL)-listed CAT III and/or CAT IV test meter. Garments must have a minimum arc-rating of 8 or more. In 2009, the NFPA published a more polished, clearer 70E standard and continued with the 2012 edition, covering shock and arc flash hazards for direct current (DC) systems. The videos, white papers, brochures and other materials in our Resource Center can help. To make the testing easier, have one person in charge of all rubber glove testing. All rights reserved. To protect against shock hazards, some basic equipment should be available and used. This is in addition to the shock protection required in Part 2 above. However, the National Fire Protection Association's Standard for Electrical Safety in the Workplace, It states, “Employees shall wear arc rated clothing wherever there is a possible exposure to an electric arc flash above the threshold incident energy level for a second degree burn (1.2 cal/cm2).” This requires employees working on or near energized parts and equipment to wear flame resistant (FR), arc rated clothing that meets the requirements of ASTM F1506 and is appropriate to the potential energy of the hazard. Table 130.7(C)(6)(c) list the standards that indicate maximum test intervals for rubber insulating equipment and what they are. To cite specific electrical PPE requirements, OSHA has cited NFPA 70E under the General Duty Clause. There are two levels of assessment to consider, including: Qualified workers must also have the skills and techniques necessary to distinguish exposed live parts from other parts of electric equipment; determine the nominal voltage of exposed live parts; know the clearance distances for the various nominal voltages (i.e., NFPA restricted approach boundary); and understand several specific special precautions related to capacitors, current transformers (CTs), lighting requirements, gradient potential (medium voltage or over 600 volts (V)), PPE requirements, and emergency response related to electrical contacts. Analyze, compare, and assess OSHA electrical safety regulations and NFPA 70E electrical safety consensus standards; Take measures to avoid workplace safety violations, injuries, and fatalities related to electric shock and arc flash hazards; Identify methods for determining what PPE is necessary; Determine your training obligations for qualified and unqualified workers. While safety should be your first priority, equipping your workers with professional looking uniforms will not only boost employee morale but also help build your brand’s image. It may also help to have two different colors of gloves. for 480- or 575-V work). OSHA explains this MAD as “arms reach plus 12,” so rubber gloves are required before opening the door or removing a cover to expose parts. This guide will provide an explanation on all the major changes that have been implemented in new NFPA (National Fire Protection Agency) 70E 2018 edition. It doesn’t have to be a stressful process. To supplement everyday uniforms, arc flash suits and hoods in double-layer Westex ® DH, Westex ® DH Air TM, Westex UltraSoft®, UltraSoft AC® and Indura® combinations are available for higher energy PPE Category 3 & 4 level tasks. Anything above this level will cause a second-degree burn to bare skin. While some brighter visible colors may be required by your work environment, you can still use colors similar to your company’s brand. A medium voltage requires higher-rated gloves, in addition to the use of hot sticks and grounding equipment. If you are familiar with the concept of Arc flash studies, then you must also know the significance of Arc flash labels in … Velcro patches for easy to add and remove logos and name tags. The level of this “job briefing” depends on if the work is routine or nonroutine and the complexity or level of risk of injury to the employee. Arc flash and blast hazards present more of a challenge. Any work on equipment for which the hazard level is greater requires the equipment to be de-energized or the hazard engineered out via remote working procedures. The PPE required includes rubber gloves, EH-rated boots (suggested), a hard hat with arc shield, plastic-rimmed glasses, ear plugs, and arc-rated clothing to the level of the hazard. Please refer to NFPA 70E Annex H.2 Simplified Two Category Flame Resistant (FR) Clothing Approach. Leather protectors should be used to protect the Class 0 rubber gloves (required for Class 1–4 gloves). Your Electrical Safety Program. All rights reserved, Copyright © 2020 Business & Legal Resources. With this requirement, each qualified worker should determine the shock hazard by identifying the exposure to electrical parts, the nominal voltage of those parts, and shock PPE required for adequate protection within the determined minimum approach (or NFPA 70E restricted approach) boundary. The NFPA 70E gets updated every three years. Yes, Table 130.7(F) indicates the standards that other personal protective equipment is to comply with. The interpretation on the use of PPE, along with the definition of “qualified worker,” is now more clear than ever. Give us a call today and discover what a premier uniform provider can do for you! The current Standard is NFPA 70E … The following is a chart of required garments for each hazard rating and the appropriate garments to use for each: Garments must have a minimum arc-rating of 4 or more. Consult the standards for complete details. Many companies simplify compliance to NFPA 70E through everyday uniform programs using garments made with Westex-brand FR fabric that meet the requirements of NFPA 70E PPE Categories 1 and 2 as a single-layer. This will provide information needed to determine the shock prevention measures. Rubber gloves are required to be air tested before each day’s use and lab tested at least every 6 months. To be defensible, companies must develop a written program based on a hazard assessment, train employees, verify the program works, and enforce the program. The simplest way to comply with arc-rated clothing requirements is to have qualified workers wear 8 cal/cm² for day-to-day work (a less effective but functional option is coveralls of the same rating over cotton clothing) and wear an arc shield for any work for which the incident energy was determined to be less than 8 cal/cm². 920 Milliken Rd, Spartanburg, SC 29303 | 800.334.4842, I consent to receive digital communications (including email, social, and re-targeting ads) from Westex by Milliken.
