Question: 1 / 400

What do the two gauges on oxygen and acetylene tanks indicate?

Temperature and humidity

Weight and pressure

Pressure and content

The two gauges on oxygen and acetylene tanks are designed to provide crucial information about the contents of the tanks. One gauge displays the internal pressure of the gas in the tank, which is important for ensuring safe operation and managing the flow of gas during use. The second gauge serves as an indicator of how much gas is remaining in the tank, helping users assess whether they need to refill or replace the tank.

The pressure gauge is essential because it allows the user to monitor the safety of the tank under various operating conditions. If the pressure is too high or too low, it could indicate a problem that may need addressing. Meanwhile, understanding the tank's content level is vital to avoid running out of gas during critical tasks, which could lead to interruptions or safety hazards.

Overall, these gauges play a fundamental role in the safe and effective use of oxygen and acetylene tanks, making option C the correct choice.
