What is the maximum storage temperature recommended for gas cylinders?

1. 100 degrees F

2. 100 degrees C

3. 130 degrees F

4. 130 degrees C

The correct answer is: 130 degrees F

The maximum storage temperature recommended for gas cylinders is crucial for ensuring safety and maintaining the integrity of the gases within them. Gas cylinders, especially those containing flammable or toxic gases, should be stored in environments that minimize risks associated with temperature extremes. The choice of 130 degrees Fahrenheit (F) is based on guidelines provided by safety organizations and the manufacturers of gas cylinders, which indicate that temperatures higher than this can lead to increased pressure inside the cylinders. Elevated pressures can increase the risk of cylinder rupture or failure, potentially leading to dangerous incidents, such as explosions or the uncontrolled release of gases. In contrast, the other options present either significantly lower or excessive temperature thresholds. For instance, a maximum of 100 degrees F may be seen as too conservative considering the need for operational flexibility, while 100 degrees Celsius and 130 degrees Celsius represent temperature ranges that could dangerously escalate gas pressures within the cylinders, posing serious risks. Therefore, maintaining a maximum storage temperature of 130 degrees F ensures effective operational limits while also upholding the safety of personnel and surroundings.
