At depths of 45 FSW or shallower, how should the inside tender handle the mask?

At depths of 45 feet of seawater (FSW) or shallower, it is important for an inside tender to ensure that the mask is not strapped tightly to the diver’s face. The reason behind this is primarily related to comfort and safety. If a mask is secured too tightly, it could cause significant discomfort and potentially impair the diver's ability to equalize pressure in the mask, which is crucial during ascents and descents.

In shallower waters, the pressure changes are less significant compared to greater depths, so a snug fit is essential to prevent water leakage without being overly tight. If the mask is too tight, it may create a seal that is difficult to break, leading to discomfort and stress for the diver. The inside tender's responsibility in this situation includes monitoring the diver's condition and ensuring that gear is comfortable and functioning properly for optimal performance and safety.
