Safety

 

 

Electrical construction is dangerous work. Electrical contractors and workers must always adhere to safety best practices. Just what are those practices? The following articles, listed chronologically by date, document safety measures and practices that help ensure everyone gets home safely at the end of the work day. 

In recent years, thousands of occupational fatalities and injuries have occurred as a result of electrical contact. Many of these accidents happen when workers do not use the appropriate personal protective equipment (PPE) for the job or they use it improperly.

System upgrades, short-circuit current


It goes up. It goes down. Sometimes, it is thought to be infinite (although it isn’t), and other times, it seems impossible to find. The available short-circuit current from the electric utility is one of the more important pieces of information for an arc flash hazard calculation study.

Fires and explosions in the workplace result in nearly 200 fatalities and injure some 5,000 workers every year. The resulting costs of such incidents reach more than $2 billion annually.

The current economic climate in Washington, D.C., is uncertain at best. Last minute approval of the federal budget in late December would seem to offer a little more insight into how the Occupational Safety and Health Administration (OSHA) will operate in 2014.
