What is the standard pressure for an open circuit scuba cylinder?

• A. 2,000 psi
• B. 2,500 psi
• C. 3,000 psi
• D. 3,500 psi

Answer: (C)

The standard pressure for an open circuit scuba cylinder is 3,000 psi. This pressure allows divers to store a sufficient volume of breathing gas in a compact and manageable cylinder, supporting safe and effective underwater operations. Scuba tanks are commonly designed to hold gas at this pressure, ensuring that divers can breathe comfortably while diving without the risk of running out of air too quickly. While options like 2,000 psi or 2,500 psi may represent pressures found in some older or smaller tanks, and 3,500 psi is generally associated with technical diving or specialized tanks, 3,000 psi is the most prevalent standard for recreational scuba diving cylinders. This is key in providing divers the ability to safely conduct their activities without compromising on the air supply needed for decompression and emergencies.
