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.
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.
