What medical clearance is required for commercial divers?

• A. A current diving medical examination
• B. A dental check
• C. A general health questionnaire
• D. No medical clearance required

Answer: (A)

For commercial divers, medical clearance means a current diving medical examination performed by a qualified physician (often one trained in diving medicine or occupational health). This specialized assessment goes beyond a general checkup and evaluates whether you are fit to dive, taking into account how the underwater environment and pressure changes can affect the heart, lungs, ears, sinuses, vision, and overall physical ability. It also considers medications, underlying conditions, and factors like pregnancy or recent surgery that could pose risks underwater. The result is formal clearance to dive for a specified period, after which re-evaluation is required. A dental check or a general health questionnaire alone does not establish the required fitness to dive, and having no medical clearance would prevent working as a commercial diver.
