NFPA 70E, Standard for Electrical Safety in the Workplace defines safe work practices for electrical construction and maintenance; the primary message of NFPA 70E is to turn off the power before working on electrical equipment.
Historically, shock and electrocution have been seen as the primary electrical hazards to people, along with fires of electrical origin, but today, awareness is growing of two other electrical hazards: arc-flash and arc-blast.
By July 17, 2006, the multiyear initiative by the Institute of Electrical and Electronics Engineers (IEEE) and the National Fire Protection Association (NFPA) had received an initial $1.25 million in contributions from the industry.
Ensure your safety with a pre-trip inspection Motor vehicle crashes are a leading cause of death and injury for all ages. Crashes occurring on the job have profound financial effects on employees, their families, coworkers and employers.
Interpreting swimming pool code requirements The May 2005 Code Applications column, “Going For a Swim,” contained information on a major change in Article 680 for the 2005 National Electrical Code (NEC) concerning the construction requirements of fiberglass pools, vinyl-lined pools and concrete pool
Subpart V revisions and line construction The Occupational Safety and Health Administration (OSHA) estimates that 444 serious injuries and 74 fatalities occur annually among employees involved in electric power generation, transmission and distribution work.
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.
