What is essential for a company officer in terms of air supply during operations?

A company officer must ensure that no crew member works beyond their anticipated air supply because the availability of breathable air is critical during operations. It is essential for maintaining the safety and well-being of all personnel. Each crew member has a limited air supply, determined by their individual usage rate and the capacity of their air tanks. If a crew member exceeds their anticipated air supply, they risk running out of air, which can lead to a life-threatening situation.

By managing air supply effectively, the officer can help ensure that all personnel involved maintain a safe and sufficient level of air while performing their duties. This proactive approach not only safeguards individual crew members but also enhances the overall effectiveness of the operation, as all team members can continue to perform their tasks without the risk of compromising their safety due to air depletion.
