Counterfeiting Kills

Each year, the counterfeiting of well-known brands and products continues to rise, creating an even more threatening problem. Such well-known counterfeited brands, including consumer safety and critical electrical products, are estimated to be five to seven percent of world trade. The International Anti-Counterfeiting Coalition (IACC) estimates that the counterfeiting of distinguished brands costs industries $600 billion each year worldwide and may result in as many as 750,000 lost jobs every year in the United States.

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...
