Control of Hazardous Energy

4. hold energy-isolation devices in a safe or “off” position.
6. Energy converted from the combustion of gases, liquids, solid chemicals, and vapors.
7. refers to specific practices and procedures to safeguard employees from the unexpected energization or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities.
8. Energy generated through the conversion of other forms such as mechanical, thermal, or chemical energy.
9. Stored energy that can be drawn upon to do work. Suspended loads, compressed springs, and pressurized hydraulic systems are examples.

1. Energy sources including electrical, mechanical, hydraulic, pneumatic, chemical, thermal or other sources in machines and equipment that can be hazardous to workers.
2. The capacity of a substance to do work or produce heat through a change in its composition.
3. Energy resulting from moving objects such as released loads and uncoiling springs. When these objects are released, their potential energy is converted to kinetic energy.
5. are prominent warning devices that an authorized employee fastens to energy-isolating devices to warn employees not to reenergize the machine while he or she services or maintains it.
10. Energy transferred from one body to another as the result of a difference in temperature.
