In 1997, U.S. Customs and Border Protection (CBP) began a nationwide program targeting electrical merchandise with counterfeit Underwriters Laboratories Inc. (UL) certification marks being imported from Asia.
A utility-interactive photovoltaic (PV) system is defined in Section 690.2 of the National Electrical Code (NEC) (NFPA 70-2005) as a “photovoltaic system that operates in parallel with and may deliver power to an electrical production and distribution network.” NEC Article 690 covers Solar Photovol
All or nothing doesn't necessarily cut it in integrated systems. Now, end-users can integrate all or some of their building management and security functions-letting the level of integration fit the facility.
Like most professions, electrical construction requires attention to proper selection and care of tools. Tool safety for electrical work has many facets. The wrong tool or a tool in disrepair can lead to injury. In addition, certain tools used by electricians serve as a form of protective gear.
The Hazard Communication Standard (HazCom) continues to be one of the top 15 OSHA standards violated by electrical contractors. It was first developed to protect against the possibility of chemical-source injury or illness.
Ken Mastrullo is having a busy year. Between February and June 2005, the NFPA 70E senior electrical specialist traveled to 15 different sites in the United States and Canada to educate groups about the standard that is defining electrical safety.
Nonmetallic-sheathed (NM) cable with less pulling resistance? Self-healing aluminum cables? Cable that burns with limited smoke? Cable is not just cable anymore. If you are like me, you grumble when things go awry.
The following series of fatalities was studied by the National Institute of Occupational Safety and Health (NIOSH). Each involves contact with energized lines or equipment. In every case, NIOSH came to the same conclusion. After reading them, you can compare your thoughts to that conclusion.
The tools electricians use every day pose the risk of injury-ranging from banging a thumb with a hammer to serious accidents with power tools. And when projects require working near live conductors or circuit parts, using the wrong tool or making a simple mistake can have fatal results.
The emphasis the Occupational Safety and Health Administration (OSHA) places on education and training for accident prevention is demonstrated by the number of standards on the topic and the number of citations issued for lack of training.
Periodically, it is a good idea to take a look at the Occupational Safety and Health Administration's (OSHA) activities and their plans for the future. This is particularly true following a presidential election.
Personal protective equipment (PPE) is often worn by employees without regard to its purchase, need or use. However, employers are required to know when and why employees must wear PPE and ensure it is used properly.
Using a personal fall arrest system is no different than using any other personal protective equipment. In the hierarchy of protection, it is the last resort. The first step should be to remove fall hazards through engineering controls, such as guardrails.
Twenty-five years ago, the National Fire Protection Association (NFPA) first prepared a set of standards to ensure electrical workers were safe on their jobs. So why has this standard-known as the NFPA 70e-suddenly become such a big deal?
