HAZARDS AROUND

While working live in the energized grid, presence of voltage around the workers requires special attention. However, live-line (live working) techniques are widely applied for decades, several accidents in the past prove that the level of safety must be improved to minimize the number and seriousness of injuries in the future.
In the high voltage grid, bare-hand method is a common technique for safe live work. In the surroundings of any energized equipment,...

How to reduce electrical-related deaths and injuries to zero

BY JENIFER ROBERTSON, Electrical Safety Authority

Consider this scenario: An electrician is modifying an electrical circuit in a ceiling space at an educational institute. To perform the task, he de-energizes his specific circuit, but leaves the others in the same junction box energized.

While making the wiring modifications, the electrician makes incidental contact with a 347-volt, energized conductor with his right thumb and baby finger. He receives a shock.

Does this sound like a rarity? Well, it is not. In fact, this is a real-life incident that happened in Ontario—and it...

Guide to Arc Flash Apps

Arc flash applications are increasing in popularity among engineers and electricians when examining hazards presented by an arc flash. Professionals search for accessible tools to help reduce dangers associated with arc flash as well as to assist in selecting adequate personal protective equipment (PPE). Mobile apps for arc flash analysis can be useful for assessing the hazards before working on energized equipment.

Contrary to many simple and complex computer programs used for power system and arc flash hazard analysis, only a handful of arc flash apps are available for purchase. Each app, available in either the Apple Store (iPhone) or...
