Hazardous energy in occupational safety and health is any source of energy (including electrical, mechanical, thermal, chemical, hydraulic, and pneumatic sources of energy) that "can be hazardous to workers", such as from discharge of stored energy.
There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the nuclear force acting on the baryon charge is called nuclear potential ...
The energy in joules can be calculated from the capacitance (C) of the object and the static potential V in volts (V) by the formula E = ½CV 2. [27] One experimenter estimates the capacitance of the human body as high as 400 picofarads , and a voltage of 50,000 volts, discharged e.g. during touching a charged car, creating a spark with energy ...
Natural gas is often sold in units of energy content or by volume. Common units for selling by energy content are joules or therms. One therm is equal to about 1,055 megajoules. Common units for selling by volume are cubic metre or cubic feet. Natural gas in the US is sold in therms or 100 cubic feet (100 ft 3). In Australia, natural gas is ...
Flammable applies to combustible materials that ignite easily and thus are more dangerous and more highly regulated. Less easily ignited less-vigorously burning materials are combustible . For example, in the United States flammable liquids , by definition, have a flash point below 100 °F (38 °C)—where combustible liquids have a flash point ...
The potential energy stored in an explosive material may, for example, be: chemical energy, such as nitroglycerin or grain dust; pressurized gas, such as a gas cylinder, aerosol can, or boiling liquid expanding vapor explosion; nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239
The "kiloton (of TNT equivalent)" is a unit of energy equal to 4.184 terajoules (4.184 × 10 12 J). [6] A kiloton of TNT can be visualized as a cube of TNT 8.46 metres (27.8 ft) on a side. The "megaton (of TNT equivalent)" is a unit of energy equal to 4.184 petajoules (4.184 × 10 15 J). [7]
Planck energy (E P) – natural unit of energy common in particle physics (~1.96 × 10 9 J). Barrel of oil equivalent (BOE) – energy unit equal to the energy released when burning one barrel (159 litres) of oil (~6.12 GJ). Tonne of oil equivalent (toe) – energy unit equal to the energy released when burning one tonne of oil (~42 GJ).
