OTU
OTU (Oxygen Toxicity Unit) is a measurement used in scuba diving to track how much oxygen exposure a diver has received during deep or long dives. Think of it like a safety counter that helps diving instructors ensure their students stay within safe limits when using special breathing gas mixtures. It's similar to tracking UV exposure time in the sun - there's a daily limit that shouldn't be exceeded. When you see this term in resumes, it usually indicates that the person has advanced diving experience, especially in technical diving or diving instruction.

Example Interview Questions
Senior Level Questions
Q: How do you plan extended diving operations while managing OTU limits for a group?
Expected Answer: Should explain how they track oxygen exposure for multiple divers, create schedules that balance activity with safety limits, and handle emergency procedures if limits are approached.
Q: What procedures do you implement for OTU monitoring in a diving school?
Expected Answer: Should describe creating clear tracking systems, training other instructors, maintaining logs, and establishing clear safety protocols for different types of diving activities.
Mid Level Questions
Q: How do you explain OTU limits to new technical diving students?
Expected Answer: Should demonstrate ability to explain complex safety concepts in simple terms and describe practical methods they use to help students track their exposure.
Q: What factors affect OTU accumulation and how do you adjust for them?
Expected Answer: Should show understanding of depth, time, and oxygen percentage relationships, and explain how they modify dive plans based on these factors.
Junior Level Questions
Q: What is an OTU and why is it important in diving?
Expected Answer: Should be able to explain basic concept of oxygen exposure measurement and why it matters for diver safety in simple terms.
Q: How do you calculate basic OTU limits for a single dive?
Expected Answer: Should demonstrate knowledge of basic calculations and understanding of daily exposure limits for regular diving activities.
