What icon indicates that a successful self-test has occurred?

The icon that indicates a successful self-test has occurred is commonly represented by the word "GO." This icon signals that the SCBA has passed all diagnostic checks and is functioning properly, making it safe to use. The "GO" icon reassures the user that all systems are operational and that they can proceed with their intended task without concerns about equipment failure. The clarity of this indicator is crucial in emergency situations, where confidence in the equipment can be a matter of safety and effectiveness. This positive affirmation helps users quickly assess their gear’s readiness at critical moments.
