A compressed-gas cylinder is rolled with its regulator exposed and no cap or cart restraint. What handling correction is necessary?
- ACarry it with oily gloves
- BRoll it by the valve
- Cap and secure the cylinder using approved handling methods
- DHeat it to increase pressure for the described HVAC equipment and measured operating conditions
Why C is correct
The best answer is: Cap and secure the cylinder using approved handling methods. A broken valve can turn a high-pressure cylinder into a projectile. Caps, restraint, approved carts, and clean compatible fittings control mechanical and pressure hazards. The transferred operating condition requires the same design, installation, diagnostic, or safety principle in a different HVAC context. The other choices skip a prerequisite, conflict with the listed procedure, or treat a symptom without controlling its cause.
