Question

flashback can cause cat... hic failure of __. a hoses b regulators c compressed gas cylinders d all of these e none of these

Explanation:

Flashback refers to the reverse flow of gas. It can cause high - pressure shockwaves. Hoses can be damaged by the force of the shockwave. Regulators, which control gas pressure, can also be affected by the abnormal pressure changes during flashback. Compressed gas cylinders, due to the potential for pressure surges and the transfer of heat (if there is combustion associated with flashback in some cases), can be at risk of catastrophic failure. So all the mentioned components (hoses, regulators, compressed gas cylinders) are potentially subject to catastrophic failure due to flashback.

Answer:

D. All of these
