Question

Quizplus · Accepted Answer

Nitrous oxide and oxygen cylinders have different outlet sizes and thread types, so a nitrous oxide cylinder with a different outlet size and thread type cannot be attached to oxygen equipment. Nitrous oxide cylinders have internal threading, whereas oxygen cylinders have external threading, which makes them incompatible. Therefore, option 1 is incorrect, and options 2 and 3 are also incorrect. The correct answer is option 4, which states that nitrous oxide cylinders have a different outlet size and a different thread type from oxygen cylinders.
