Which color indicates dangerous machinery parts?

The color that indicates dangerous machinery parts is orange. This color is commonly used in industrial settings to signal caution and highlight equipment or areas that may pose a risk of injury or hazard. Orange serves as a visual warning to workers to be particularly vigilant in those areas, therefore enhancing safety.

In many safety standards, including OSHA (Occupational Safety and Health Administration) guidelines, orange is recognized for its visibility and ability to draw attention, making it an effective color for warning signs and markings. The use of this color helps ensure that operators and maintenance personnel are aware of potential dangers and can take appropriate precautions when working near or with machinery.

Other colors, although they have their own meanings in safety protocols—such as red for emergency stops or fire equipment—do not denote dangerous machinery parts specifically. In contrast, black generally represents general background information and isn't used to indicate danger, while white is associated with cleanliness and areas free of hazards.
