What colors indicate the PBE is secure and functional?

The indication that the PBE (Protective Breathing Equipment) is secure and functional is represented by the colors blue and green. These colors are specifically chosen to signal that the equipment is in proper working order and ready for use. In emergencies, having clearly recognizable signals is crucial for quick identification of functional equipment. This color-coding helps personnel quickly ascertain whether the PBE can be safely utilized during a crisis, ensuring the safety and well-being of those responding to emergencies. Proper understanding and recognition of these colors are fundamental for effective emergency preparedness and response.
