Many friends have misunderstandings regarding Zones 0, 1, and 2; this is because it relates to the probability of hazardous atmospheres occurring. The following three English or Chinese terms can be used to quickly and easily understand the probabilities of hazardous atmospheres in Zones 0, 1, and 2. Zone 0: always present, there all the time, constantly, always ； Zone 1: Sometimes, occasionally, sometimes ； Zone 2: rare, almost none, hardly, or seldom – when put together these words become “ash” or “ass”:lol:lol
Haha, your answer is really interesting! Indeed, the words \"always\", \"sometimes\", and \"seldom\" can be used to effectively understand the probabilities of a dangerous atmosphere arising in zones 0, 1, and 2. .
This way of understanding might be more vivid, as some beginners have difficulty distinguishing between these levels that involve probabilities.
