What is the number of first aid kits present in a CRJ900?

In a CRJ900 aircraft, the standard configuration includes two first aid kits. This is in line with regulatory requirements for passenger aircraft, which dictate that there should be sufficient first aid supplies to address potential medical emergencies. The presence of two kits ensures that there are adequate supplies readily available, distributed for accessibility, and allows the crew to attend to multiple medical situations if needed.

Having two first aid kits is a common practice in aviation, as it enhances safety and preparedness among the crew and passengers alike during a flight. The existence of additional first aid kits beyond this standard configuration is generally unnecessary unless specified for specific operational requirements.
