What It Involves
A quick, non-invasive measurement of your height and weight to calculate BMI. Several safety-critical medicals (offshore, maritime, wind) use BMI or chest-measurement thresholds because survival suits and emergency evacuation equipment are only rated for a certain size range - a high or low BMI can trigger a closer look, not an automatic fail.
What to Bring
Valid photo ID (passport or driving licence) (and 2 more items)
Frequently Asked Questions
There's no single automatic fail threshold - a high or low BMI can trigger extra checks (e.g. a chest measurement for offshore survival-suit fit) rather than an automatic refusal.
No - the reading is just a snapshot, and crash-dieting beforehand won't change the underlying assessment your doctor is making.
Health questionnaire
If your clinic requires a pre-visit health form, we'll email you their link. You complete it directly with the clinic — we never see or store your answers.
