Personnel safety around energized equipment is only part of the picture when it comes to electrical safety. The other part is the installation, and whether the job was performed correctly. […]
According to the National Institute of Occupational Safety & Health (NIOSH), electrical hazards cause more than 300 deaths and 4,000 injuries in the workplace each year. Electrical accidents are ranked 6th among all causes of work related deaths in the United States. Always work safely, wearing the proper PPE for your situation and know what [...]
Electrical maintenance requires a basic understanding of electrical theory and electrical safety. Basic Electrical Theory For a full understanding of electrical theory, please click here. One of the most important theories in electricity is Ohm’s law. It basically defines how electricity will behave in electrical circuits. This is not to say that there are no other [...]
Boiler Basics A boiler is used to heat water that is circulated through a closed loop piping system for general facility and service water heating. Low-temperature systems generally operate below […]
Conveyor belt systems have been responsible for over 80 serious or fatal accidents in the U.S. over the last 20 or so years. According to a report featured by the American Society of Safety Engineers, […]
Corrosion can be a serious issue. Not only can it affect operating costs, it can also be a hazard to personnel. We all understand that piping ravaged by corrosion must in many cases be repaired […]
Roughly 20% of the electricity produced in the United States every year is used to power industrial facilities and equipment. While electricity makes it possible for these facilities to operate, it also poses a very real hazard, with several hundred electricity-related fatalities occurring at the workplace every year. In order to avoid or treat electrical [...]
DC generators are widely used to produce a DC voltage. The amount of voltage produced depends on a variety of factors. A basic DC generator has four basic parts: a magnetic field; a single conductor, or loop; a commutator; and brushes. The magnetic field may be supplied by either a permanent magnet or an electromagnet. [...]
I’ve always wondered how many people, after viewing one of those do-it-yourself shows, think “that looks easy! I should be able to do it.” I cringe when they install electrical circuits or components, switches, lights, etc., and say “Don’t forget to turn off the power before attempting this.” This is usually followed by […]
Whenever an object moves against another object, friction will be present, turning kinetic energy into heat and causing equipment to wear. Using lubricants helps to reduce this friction, allowing more work […]
