What color tanks are used to store nitrous oxide (N2O) and oxygen (O2)?

The correct answer identifies blue tanks for nitrous oxide (N2O) and green tanks for oxygen (O2). This color coding system is crucial for safety in medical and dental settings, as it helps professionals quickly identify the gases being used. The blue color signifies that a tank contains nitrous oxide, a commonly used anesthetic agent that provides sedation and analgesia in various procedures. The green color indicates that a tank contains oxygen, which is essential for patient care, particularly in emergencies or during sedation procedures.

Using a standardized color coding system helps prevent dangerous mix-ups between gases that could lead to serious complications, ensuring that practitioners administer the appropriate substance to patients. Familiarity with these colors is foundational for dental assistants and other healthcare providers to promote a safe working environment.
