As a Repair Party Investigator, if you need to go on air, what is essential for you to do?

The necessity of tracking your air time while on air is crucial because it ensures that each member of the repair party can manage their oxygen supply effectively. Air supply is limited, and understanding how long each person has been using the air allows for proper planning and ensures that there's enough oxygen available for all members involved in the operation.

Monitoring air time can help in making informed decisions about when to rotate personnel, thereby preventing situations where someone might run low on air while others still have supplies available. This practice not only enhances individual safety but also contributes to the overall success of the damage control operation.
