Choosing and using test equipment correctly is critical There are no proven tricks or shortcutsthat will estimate the voltage in a circuit. Qualified workers must use a tester to determine if the wires or equipment are energized.
There are a limited number and amount of chemicals that electricians use to perform their work. Wire lubricants, contact cleaners, etc., are used in sparing quantities. However, the number and variety of substances they can be exposed to is unlimited.
It is common knowledge that too much sun and heat are dangerous. What electrical contractors may find surprising is the impact of these hazards and the control the Occupational Safety and Health Administration (OSHA) may exercise over an employer for providing protection.
As usual, there is much to report on changes involving the Occupational Safety and Health Administration (OSHA). New legislation has been proposed, advances have been made on proposed regulations, and new cooperative programs and materials have been created.
Since 1970, when the Occupational Safety and Health Administration (OSHA) was established, it seems as though there has been no end to the addition or changing of regulations. Fortunately, time has provided advances in technology to cope with the growing number of requirements.
The North Carolina Occupational Safety and Health Administration (NCOSHA) Division of Safety Research investigated the fatal fall of an electrical mechanic. The mechanic had fallen through an unguarded floor opening.
Time and again, electricians are told to deenergize for compliance and safety. Of course, there are exceptions. The question is what justifies an exception. Answering this requires a review of the regulation. To apply it to real life, one needs something more thought-provoking.
On certain jobs, electricians can find themselves in an environment where the noise level exceeds the Occupational Safety and Health Administration’s (OSHA) time-weighted average limit of 90 decibels. A noise level of 90 decibels is approximately that of a lawn mower or subway train.
While taking time to look at the construction year ahead, don’t forget safety. While preparing your 2006 Occupational Safety and Health Administration (OSHA) Form 300A, Summary of Work-Related Injuries and Illnesses (posting deadline Feb. 1), reflect on changes needed to prevent future accidents.
Months after the devastation caused by hurricanes Katrina and Rita and the flooding that followed, cleanup efforts in New Orleans and Gulf Coast areas slowly continue. In many areas, rebuilding has yet to begin. The electrical industry is heavily involved in recovery efforts.
If you have been following this column, you generally read about actions to prevent injuries. At times, an accident review is used to provide insight into safety procedures that can avoid reoccurrences. This article began as a lesson in what to do to avoid an electrical shock.
A leading architecture/engineering member of the CSI revision team (who requested anonymity) described the genesis of the change to MasterFormat 2004 this way: “Division 16 was used to describe means and methods of lighting and distribution of power in buildings.
As the National Fire Protection Association (NFPA) 70E standard takes root in electrical practices, getting the right training to the right people has become the greatest hurdle in changing the way electricians do their job.
Sending a fire alarm signal is not enough. State-of-the-art fire alarm and life safety technology now allows for a host of data, instructions, graphics and other functions that get people out of danger quickly.
