What type of fluid indicates a class 1 leak when evaluating equipment?

A class 1 leak is characterized by fluid that does not accumulate, meaning it may not be readily apparent or create visible puddles. Such leaks typically involve a minor and ongoing seepage that gradually occurs but does not lead to significant fluid buildup on the ground or equipment. This type of leak is often detected through careful observation of equipment joints and seals, where slight weeping or moisture can be noticed.

The understanding of leak classification is crucial for maintenance and safety, as class 1 leaks may not demand immediate action but still require monitoring to prevent escalation. Recognizing this distinction in leak severity helps ensure that any potential issues are addressed proactively without overlooking minor but significant indicators of equipment health.
