3. Energy discrimination and isolation

Workplace energy identification

Territorial units should identify the sources and types of all energy and materials (including utility systems) used in the operation. The energy to be controlled includes, but is not limited to, the following types:

Electrical energy: the current wing electron flow;

Kinetic energy: running equipment, etc.

Potential energy: spring, compressed gas, etc.

Chemical energy: hazardous chemicals;

Thermal energy: electric heating, cooling system.
