Generally accepted industry standards, such as National Fire Protection Association (NFPA) 70E-2018, require arc-flash incident energy analysis to be updated when changes occur in the electrical power distribution system, and the analysis shall be reviewed for accuracy at least every five years. NFPA 70E also requires the data used for creating equipment labels, which contain arc-flash energy information, to be reviewed at least every five years, and, if the review identifies a change that renders the arc-flash energy label inaccurate, the equipment label must be updated.

Large engineered adjustable-speed-drive (ASD) systems are typically rated above 7 kV, with 5,000 or 10,000 hp considered engineered products and systems (i.e., one-of-a-kind or one-off designs) as opposed to off-the-shelf equipment. As such, they require more attention to application, design, system validation, and commissioning than typical off-the-shelf equipment and systems. Hazards associated with different drive topographies are sometimes overlooked during the design stage. In many cases, the design engineer considers the drive as a "black box" without sufficiently understanding the internal drive design required to identify and mitigate concerns. In some cases, manufacturers' claims may help reinforce this attitude. [ABSTRACT FROM PUBLISHER]

Occupational electrical injuries are low-frequency/high-consequence events. For an industrial facility's electrical safety resource, this means that the facility's emergency response team (ERT) may never have responded to an electrical injury case. If an electrical incident did occur, however, an electrical injury is more likely to be fatal than most other types of occupational injuries. This highlights the need for facilities to have a specific electrical emergency response plan in place to ensure that timely and appropriate actions are taken if an incident occurs. Conducting periodic electrical injury drills will test a facility's emergency readiness and identify learning and growth opportunities. When planning an electrical injury drill, the scenario and type of drills will vary depending on the type and frequency of electrical activities performed at the site, ERT training, and facility resources. Using data and observations from emergency drills conducted at different industrial sites, this article examines a variety of approaches to electrical injury drills and the information and best practices that resulted.

Discusses problems associated with counterfeited products. Any products that are purchased— PPE for workers or electrical equipment for use or installation— should be checked for signs of counterfeiting. A Source of Hazards to Workers hazard to industrial workers that gets little attention is the use of counterfeit electrical equipment and safety products. There have been many recent news articles about the seizure of counterfeit products, from electronics to medical supplies; the concern is that many untested or fake products make it into the supply stream. Most of the news is about consumer goods, and certainly fake toys, electronics, and other articles can be hazardous. [ABSTRACT FROM AUTHOR]

The article focuses on the need to manage and mitigate arc hazard in the wokplace to implement hazard control measures. It emphasizes that the most effective design and application of an arc flash mitigation program is through a collaboration involving electrical subject matter experts, safety professionals knowledgeable in safety management systems and management resources. It suggests to eliminate the arc hazard to protect people from an arc flash exposure.
