Question

Quizplus · Accepted Answer

Technician A is correct because methyl hydrate, also known as methanol, is indeed used as a de-icing fluid due to its ability to lower the freezing point of water. Technician B is incorrect because introducing alcohol into brake systems is not a practice for lubricating pneumatic valves; it can actually damage the system by deteriorating rubber seals and other components.
