Dissipating Stored Energy
Stored energy must be released after equipment has been de-energized.
Isolating and de-energizing a transformer by grounding.
Below is a list of possible sources of stored energy.
- Capacitors
- Coiled springs
- Elevated machine members
- Rotating fly wheels
- Air, gas, steam, chemical, and water systems
If the energy could return to a hazardous level, make sure that it remains isolated from the equipment until all service work is finished. Below is a list of safe practices for dissipating potential energy.
- Vent pressurized fluids until internal pressure levels reach atmospheric levels.
- Discharge capacitors by grounding them.
- Release or block tensioned springs.
- Ensure that all moving parts have stopped completely.
