Concerns have been raised about whether workers exposed to engineered nanoparticles are at increased risk of adverse health effects. The current body of evidence about the possible health risks of occupational exposure to engineered nanoparticles is...

The explosion on the Deepwater Horizon disaster oil rig on April 20, 2010 resulted in the death of 11 workers and injury to another 17 workers. In the weeks and months after, as large amounts of crude oil released from the Macondo Well, tens of thousands...

The Determination of Sound Exposures (DOSES) software was developed by the National Institute for Occupational Safety and Health (NIOSH) specifically for use by mine management and safety personnel. DOSES simplifies the record-keeping and analysis...

This publication describes the Apollo Unified S-Band (USB) System. These areas covered are USB station locations, uplink and downlink spectrums, ground station and spacecraft gross parameters, general history of operation of the system, and the functions...

Since the 1980s, violence has been recognized as a leading cause of occupational mortality and morbidity. On average, 1.7 million workers are injured each year, and more than 800 die as a result of workplace violence (WPV). These tragic deaths and...

Leading mining historian Kerby Jackson introduces us to a classic mining work in this important re-issue of "Geology and Mineral Deposits of the Loomis Quadrangle, Okanogan County, Washington". Unavailable since 1972, this important publication was...

Mining historian Kerby Jackson introduces us to a classic mining publication on ore sampling from the U.S. Bureau of Mines. First published in 1916, it has been unavailable for over a century and sheds important light on historic methods of ore sampling...

An alternating current generator, or AC generator, produces an alternating current, which means the voltage produced alternately reverses from positive to negative polarity, producing a corresponding change in the direction of current flow. Much like a...

A direct current generator, or DC generator, produces a voltage of constant polarity, which means the voltage and current do not change over time. DC generators are basically AC generators whose output voltage is switched the other way round at the...

The satisfactory performance and continuous reliability of electrical system greatly depends on the quality of wiring. Improperly or carelessly installed wiring can be a source of both immediate and potential danger, and many malfunctions and failures...

Circuit control in its simplest form, is the application and removal of power. This can also be expressed as turning a circuit on and off or opening and closing a circuit. Before you learn about the application of circuit control devices, you should know...

Too much current flowing through an electric circuit can damage the circuit and can create a safety hazard. How much current is "too much current"? That depends on the circuit and its components. For some circuits, 1 ampere would be too much current,...

A literature-based study was conducted at the Building and Fire Research Laboratory of the National Institute of Standards and Technology, to compare characteristics and usage of steel, copper, chlorinated polyvinyl chloride and polybutylene fire...
