After a hyperbaric exposure, flying is allowed only if cleared by a provider. Which option reflects this rule?

• A. No flying for 24h unless cleared by provider
• B. Flying is unrestricted after 24h
• C. Flying is prohibited indefinitely
• D. Only trained pilots may fly

Answer: (A)

After hyperbaric exposure, the main concern is the risk of decompression sickness when climbing to altitude. The body needs time to off-gas inert gases and for any evolving symptoms to appear or be ruled out, so a waiting period is used. Flying is permitted only after a medical provider reviews the individual and clears them, ensuring there are no contraindications. Therefore, the rule is no flying for 24 hours unless cleared by a provider. The other options don’t fit because they either relax the timing without medical clearance, imply indefinite prohibition, or bring in unrelated criteria like pilot training rather than medical risk.
