With regard to Greater Hazards, which of the following is not an example of increased or additional hazards according to OSHA 1910.333(a)(1) Note 1?

• A. Interruption of life support
• B. Deactivation of emergency alarm systems
• C. Removal of an illumination for an area
• D. Shutting down parking lot lights during the day

Answer: (D)

The main idea being tested is recognizing which action does not create an increased electrical hazard under the greater hazards concept. When safety systems or essential protections are compromised, or the work environment becomes less safe to operate around energized equipment, the hazard level goes up. Interruption of life support directly affects a patient or process that relies on electrical systems, which would clearly raise risk. Deactivation of emergency alarm systems removes a critical warning and the ability to respond quickly, increasing potential harm. Removal of illumination in an area reduces visibility and can lead to mistakes or accidental contact with live parts, again raising danger.

Shutting down parking lot lights during the day does not add to the electrical hazard in most work settings because daylight still provides ample illumination and it does not compromise safety systems or energy sources involved with the work. Therefore, it is not an example of a greater hazard.
