Pressure-relief valves should be directed upward at what degree angle when the forklift cylinder is mounted horizontally?

• A. 45
• B. 15
• C. 90
• D. 60

Answer: (A)

When a propane cylinder is mounted horizontally, the relief vent should point upward at about 45 degrees. This angle lets vented gas rise and disperse away from the operator and ignition sources, reducing the chance that gas flows toward the operator’s breathing zone or into the forklift’s controls. If the vent were aimed too shallow, gas could blow toward the operator or into the workspace below; if it were aimed too steeply, vented gas might rise straight up into overhead areas or be deflected unpredictably by wind. The 45-degree direction provides safe, practical venting that protects the operator while ensuring the relief system does its job effectively.
