What condition indicates that a pressure suit is likely leaking?

A pressure suit is designed to maintain a specific pressure to provide protection against hazardous environments. If a suit loses more than 20% of its pressure, this indicates a significant leak, which compromises the suit's integrity and the safety of the wearer. The ability of the suit to resist outside pressure or prevent the ingress of harmful substances is directly linked to maintaining its pressure levels.

Losing more than 20% of pressure suggests that the suit might be unable to provide adequate protection, leading to potential exposure to hazardous materials. Hence, monitoring pressure levels is critical, and a loss beyond this threshold signals the need for immediate inspection and action to rectify the situation. This is why an indicator of more than 20% loss correlates directly with the likelihood of leakage and necessitates attention to ensure the safety of the person wearing the suit.
