Which colors should never be cut when operating at a hybrid vehicle emergency due to high voltage cables?

In the context of hybrid vehicle emergencies, understanding the color coding of high voltage cables is crucial for ensuring safety during operations. High voltage systems in hybrid and electric vehicles typically utilize specific colors to indicate dangerous wiring that should not be cut.

The correct answer, which identifies the colors orange and blue, reflects this color coding system where orange typically denotes high voltage cables. These cables are part of the vehicle's electric power system, and cutting them can result in severe injuries or fatality due to electric shock. The blue color is also commonly associated with high voltage, particularly in connection to battery systems.

The other color combinations do not represent the actual high-risk cables in hybrid vehicles. For instance, red is often used in various electrical contexts but is not specifically designated for the high voltage systems in hybrids. Green and black often represent grounding or low voltage, while white and gray might commonly indicate neutral or other standard wiring but are not associated with the high voltage threat in hybrid models. Thus, recognizing the orange and blue cables as hazardous is essential for safe operations at a hybrid vehicle emergency.
