Arc Flash/Arc Blast Review with Safety Suggestions for Design & Maintenance

One of the hot topics in electrical and mechanical training classes is the National Fire Protection Association (NFPA) 70E. Students question what 70E is and how it relates to the National Electrical Code (NEC), if 70E is a new regulation and if not why are they just now hearing about it, and if companies are required to comply with 70E. This article will take some of the mystery out of 70E.

The notions "one tool does all" or "any tool will do" result in wasted effort, poor quality work, damage to the misused tool, and exposing the user to possible injury, according to the Hand Tools Institute, an association of American manufacturers of quality hand tools. As with hammers, pliers, wrenches and all other hand tools, design is a key element to the type of work a tool is intended to do properly and safely, says HTI. Clamps are no exception and should be selected to conform to the work they are to perform.

In the past few years, Hydrovacs and "daylighting" have gained industry acceptance by minimizing the challenges of exposing underground pipelines, fiber-optics, and utilities. "Daylighting" is a non-destructive process using pressurized water (hydro) and a vacuum system (vac) to remove soil cover, thereby allowing a visual observation of underground lines. Hydrovacs expose these facilities to daylight, thus the term "daylighting".

Unfired pressure vessel inspections - are they necessary? Absolutely. Pressure vessels must be regularly inspected and be maintained in a safe operating condition. The higher the risk, the more stringent the requirements for operating and inspecting the vessel.

The answer is, it depends. For example, a traditional cleaner/degreaser, of which there are literally hundreds on the market, generally does an adequate job of cleaning. However – and this is an ongoing problem – the majority of them basically move the contamination from one location to another. The result? This cost of hydrocarbon removal is added to the clean-up process, plus your employees could be at risk of additional from toxins in the cleaner. So, how do you clean, provide a safe product for your employees and contribute to an active pollution prevention program?

A chaotic or traumatic event can happen to anyone at any time or place. Would you be ready if it happened to you? Anything that threatens your sense of safety and security either physically or mentally can be considered a traumatic event. How well you respond to and recover from such events primarily depends on your overall state of well-being. Let's look at ways to develop the Internal Resources and External Resources you need to put yourself in the best possible position to deal with chaotic events.

We as safety professionals aren't exempt. Have you seen this: Workers don't change their actions? Tell them again (with a why-didn't-you-listen undertone). Policies and procedures not followed? Write additional (and more detailed) rules. Training didn't change their behavior? Put them through the same training again and again (until they "get it"). Try, try, try again to solve safety problems, but don't confuse persistence with obstinancy.
