What tag is used to warn ramp personnel against operating ground equipment?

The ME-250 tag is used specifically to indicate warnings and alerts regarding the operation of ground equipment in ramp environments. This tag system is designed to enhance safety by clearly marking equipment that should not be operated or is under maintenance. By using the ME-250, ramp personnel are notified of potential hazards and are instructed to take caution. The existence of a standardized tag like the ME-250 helps facilitate communication among team members, ensuring everyone is aware of the status and safety of ground equipment. This contributes to overall safety and operational efficiency on the ramp.

In contrast, other options do not represent commonly recognized tags within the ramp operations framework, making ME-250 the definitive choice for this safety measure.
