Why do we need to control hazardous energy sources? Select correct answer.

Radiation can result in cancer in the long term

To prevent against unexpected start-up or release of hazardous energy.

To generate electricity

While servicing or performing maintenance on equipment, employees are exposed to unexpected start-up or release of hazardous energy. As such, we need to ensure persons who work on or around hazardous energy sources are aware of the dangers and are protected from an unexpected release.

These situations may include which of the following?

Servicing, maintaining or repairing mechanical equipment where rotating or moving parts could create a hazard.

When working on pipelines that carry hazardous chemicals (e.g. high pressure, toxic, corrosive, etc.).

On electrical circuits and systems where a risk of electrical shock exists.

Where other hazardous energies exists that may cause injury if released during service or maintenance.

All answers listed
