Safety

In 2001, close to 100,000 people were treated in U.S. Hospital emergency rooms for eye injuries related to the workplace, yet this figure actually only represents a small portion of the total number of injuries. According to the U.S. Bureau of Labor Statistics, each day, as many as 2,000 workers incur eye injuries related to their jobs. According to Prevent Blindness America (PBA), 90% of these injuries are preventable.

There are three basic electrical hazards that cause injury and death: shock, arc-flash, and arc-blast. Following these safety principles can result in a safer work environment and prevent injuries or even death.

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.

A confined space is defined as a workspace that is fully or partially enclosed, is not designed or intended for continuous human occupancy and has limited or restricted access, exiting or an internal configuration that can complicate provisions of first aid, evacuation, rescue or other emergency response services. Confined spaces can be found in almost all industries in Canada, which include tunnels, mines, grain silos, hydro vaults, shipping compartments, pump stations, boilers, chemical tanks and more. Every confined space is considered to be hazardous unless deemed not so by a competent person through a hazard identification and risk assessment.

Significant engineering and test efforts
have been undertaken in the last few years into the area of arc flash/blast hazards in electrical equipment. The result has been a better understanding of arcing faults and how to prevent and/or minimize the hazards to personnel and equipment. This paper highlights some of the findings that may help in safety management and equipment selection. This paper concludes with some design considerations that will help reduce the hazards of arcing faults.

On the job accidents and injuries are most often a result of negligence and unsafe working conditions. In an effort to protect workers, the Occupational Safety and Health Administration (OSHA), created standards 1910.132 and 1910.133, to address requirements for providing Personal Protective Equipment (PPE) and eye protection in the workplace. However, most employers find it hard to sort through the standards to get to the heart of what they really mean in everyday life.
