Learn MoreStored energy can be mechanical, gravitational, hydraulic, or pneumatic. Common examples are: Capacitors, springs; elevated components; rotating flywheels; hydraulic lift systems; air, gas, steam, water pressure; cliffed grain; etc. Mechanical – energy is contained in an item under tension.
Stored energy (also residual or potential energy) is energy that resides or remains in the power supply system. When stored energy is released in an uncontrolled manner, individuals may be crushed or struck by objects, moving machinery, equipment or other items. How does it work? Stored energy is energy in the system which is not being used.
While most people think about lockout hazards when discussing “stored energy,” potential and elastic stored energy can also be very dangerous. This new video is designed to raise your employees' awareness of all types of stored energy hazards in the work environments where they can be found.
That weight is a type of stored energy, also called potential energy. The higher the object is from the ground, the greater its' stored energy. Another kind of stored energy to be aware of is called “elastic stored energy.” For example, when a bungee cord is slack it contains no stored energy.
