What are two classifications of hazardous energy sources?

The classification of hazardous energy sources includes potential and kinetic energy. Potential energy is the stored energy in a system, which can create hazards if released unexpectedly, such as when a load falls or a compressed spring suddenly releases. Kinetic energy, on the other hand, is the energy of motion. This can also pose hazards, especially in systems where moving parts can cause injury if they are not properly controlled or guarded.

Understanding these two types of energy is crucial for implementing effective safety measures. Identifying potential energy sources helps workers recognize situations where unexpected releases could occur, while acknowledging kinetic energy allows for precautions to prevent accidents related to moving machinery.

The other classifications, while valid forms of energy, do not represent the primary categories relevant to hazardous energy sources in the context of safety practices for electricians.
