Working at height: how to prepare for the medical check

Working at height needs both physical readiness and the right precautions. This guide explains what the medical check covers, why each item matters, and how to prepare.

Published 24 September 20265 min read

Why the checks are stricter

Work at height, whether on scaffolding, roofs, masts, structures or elevated areas from two metres up, carries different risks from ground-level work. If a worker faints, becomes dizzy or cannot see clearly while elevated, the consequences can be far more serious than a fall at ground level.

Pre-employment and periodic checks aim to identify the risks that could lead to a fall or serious accident, and to help the safety team plan appropriate controls.

What is usually tested

Requirements differ between employers, but common items include:

  • History of conditions that risk fainting, such as heart disease, epilepsy, poorly controlled diabetes or severe dizziness
  • Physical examination and blood pressure measurement by a doctor
  • Electrocardiogram (EKG) when the doctor considers it appropriate
  • Chest X-ray, plus vision and colour discrimination testing
  • Hearing tests where noisy areas are also part of the job

Preparing for the day

If blood tests are included, fast for 8-10 hours; plain water is fine. Sleep well and avoid alcohol before the appointment, as both affect blood pressure and the electrocardiogram.

Bring the glasses or hearing aids you normally use so results reflect your real working ability, and tell the doctor about every medicine you take, particularly anything affecting blood pressure or heart rhythm.

How the results are used and when to retest

The result is a medical opinion on whether you are fit for work at height, with notes the safety team can use, such as reviewing protective equipment or adjusting rest schedules.

Surveillance programmes commonly require annual retesting, or retesting when job duties change or when age and medical conditions change. Check your employer's requirements before the visit.

Key points: At minimum expect a physical examination, blood pressure, vision and a chest X-ray. Prepare by sleeping well, avoiding alcohol and bringing your usual glasses. The doctor assesses readiness individually.

Will a chronic condition stop me from passing?

The doctor assesses individually whether the condition and its control affect safety at height, and may add recommendations for the employer.

Can it be done at the clinic or on site?

You can walk in at BK5 Clinic in Don Hua Lo, and for groups we can arrange an on-site visit: ask on LINE @824xsgsj.

Is an EKG always required?

Not always. It depends on your history, the doctor's judgement and your employer's requirements, since some organisations require it every time.
