Simply put, if you are the owner of a commercial facility, the 2012 updates to NFPA 70e require that an Arc Flash Study is performed and electrical enclosures are properly labeled, every five years (and following any changes to your electrical system). Crescent’s arc flash program supplies you with an engineer sealed report, equipment labels, boundary information, potential hazards, approach limits, advice on safe working practices, and all the information necessary for you to be within the latest NFPA 70e 2012 and IEEE 1584.
Opening a New Location
Profits, longevity, reputation, and safety; these are all top concerns of management when opening new location. A proactive approach to the safety of your maintenance team is paramount; if safety fails, so do your profits and your company. The concerns involved with working on live equipment is specific to each system, and these hazards are quantified as part of the arc flash hazard study. The service includes an as built one line diagram, warning label installation, and arc flash hazard study report sealed by a licensed engineer.
As the ambulance pulls away; the site coordinator is overhead telling the emergency personnel that “all we had to do was add a few circuits to the existing electrical panel”. Unknown to the contractor pulling the new wire and making terminations was that the ratings of the breakers within the panel allowed for arc flash exposure greater than the safety glasses and leather work gloves he was wearing. Any competent electrical worker is well aware of the hazards that are present, it is the level of those hazards that are always taken for granted. An arc flash hazard study (due diligence) quantifies these hazards. All studies include recommendations for hazard abatement (system improvements) and are reviewed/sealed by a licensed engineer.
Decor upgrades, structural amendments, new storefront, and a new circuit panel for the work space addition. The last item in that scope of work requires an update to an existing arc flash hazard study. Any change in electrical distribution or the addition of a backup generator can alter the exposure potential for a maintenance contractor working within a facility. An arc flash hazard study relative to retro commissioning takes into account design changes, amendments, and equipment expansions to determine just how much more or less PPE is required to service your electrical equipment. After addressing every detail at a facility throughout the meticulous process of a remodel; the safety of electrical workers should not be the only detail that is overlooked during the punch list.
