Certified Hyperbaric Technologist Practice Test 2026 – Comprehensive Exam Prep

In the context of gas cylinder color codes, the color green is universally recognized as representing oxygen. This standardization is crucial for safety and quick identification in various settings, particularly in medical and industrial environments. When personnel see a green cylinder, they can immediately identify it as containing oxygen, minimizing the risk of confusion with other gases that have different applications and properties.

Other colors such as white, blue, and yellow are designated for different gases; for example, white is often used for medical air, blue may represent nitrous oxide, and yellow is frequently used for acetylene. Thus, understanding that green signifies oxygen helps ensure that individuals working with gas cylinders can operate safely and effectively. This knowledge is essential for technicians and safety personnel in the hyperbaric field, where the correct handling and identification of gases are critical for patient care and safety.
