191 What level of protection do I need? Where do I start? »»Written Electrical Safety Program (ESP) A written electrical LLC Safety, safety program has been required by Electrical OSHA since 1991 and alisbury is a commonly cited Sof OSHA ne and oen courtesy overlooked by even good Image companies. A good ESP should include the following components: Arc and Shock Risk Assessment, Training, Auditing & Electrical Lockout Tagout. A good ESP will be based on OSHA law, an applicable consensus standard and industry best practices. NFPA 70E Electrical Safety in the Workplace covers most electrical work which is not covered by the NESC (National Electrical Safety Code) which applies to most utility installations (other than oces and occupied buildings). Choose one of these for the base of your written program. »»Arc Risk Assessment Many companies will choose to use the tables in NFPA 70E for their preliminary program, although some companies are now moving to doing a full arc ash study of electrical systems which do not meet the table requirements. is can cost a few thousand dollars for a small study with information gathered by the electricians on the site to a substantially larger sum for larger operations or turn-key approaches. oroughly vet any arc ash company. Equipment and PPE sales companies may not the best choice though there are many that are reliable. Always choose a company with a professional engineer and be certain that the contract gives you the digital les so that updates can be completed even if the company changes hands. »»Training Companies should seek in-depth training on use of the tables along with the issues and caveats in the tables. One big mistake oen made is to complicate the PPE issues by making the program too dicult. Most companies take a simplistic approach. ey choose an HRC 1 or 2 for daily wear and add the faceshield and other items as they are called for by the tables. en the company will use an HRC 4 (perhaps a 40 cal/cm2 suit or a higher level if they so choose) for those applications which require an HRC 3 or 4 arc ash suit. Choosing one suit for both 0-2 and for HRC 3-4 makes mistakes less likely and actually saves money. Taking the HRC 2 & 4 approach is one of the best methods. ere is even an optional table in the NFPA 70E standard called Annex H. is part of the standard reduces the 0, 1, 2, 3, 4 HRCs to 2 and 4. Some companies teach this to start and add sophistication as money allows for arc ash studies. Arc ash studies can point out many trouble areas and risky situations which will not be addressed by PPE alone and a good study can show simple equipment changes which can reduce arc ash energy. In some cases, companies have invested in making all arc ash energies HRC 0 (except at the main breaker leading into the building). It can also improve system reliability and help oer ideas for lessening arc energies by engineering methods. is reduces cost of PPE in some cases but it mainly reduces the risk to employees.
