What happens at a Safety Critical Medical?
A safety critical medical is required to ensure individuals working in high-risk environments are medically fit to perform their role safely. This article explains what the assessment involves, what you need to bring to your appointment, how long it takes, and how results are determined.
What is a safety critical medical?
A safety critical medical is an occupational health assessment carried out to confirm that an individual is medically fit to work in a safety critical role.
Safety critical roles are those where impaired health could place the individual or others at significant risk. These assessments are commonly required in sectors such as rail, construction, utilities, infrastructure, and other regulated industries.
The specific checks required may vary depending on the role and industry standards. In some cases, the medical may be undertaken alongside a drug and alcohol test where required by employer or industry policy.
What do I need to book a safety critical medical appointment?
Before attending your safety critical medical appointment, you will be required to provide the following:
- Current official photo identification (for example, passport or driving licence)
- Details of any medication you are currently taking
- Any corrective visual aids required for distance vision. If you wear contact lenses, you must also bring your glasses and a copy of your prescription where applicable
All required documentation must be presented at the time of your appointment. If this information is not provided, the medical may need to be rearranged and an additional appointment fee may apply.
What happens at the safety critical medical?
At your appointment, you will first be asked to complete a medical questionnaire. You will then be assessed by an Occupational Health Technician, Nurse, or Doctor.
The standard safety critical medical assessment typically includes:
- Urinalysis (to check for glucose, protein or blood)
- Epworth Sleepiness Scale questionnaire (where applicable)
- Blood pressure and pulse assessment
- Height, weight and BMI measurement
- Mobility and balance checks
- General health review
- Vision assessment, including distance vision, visual fields and colour vision
- Hearing test (audiometry)
Additional testing such as peak flow or spirometry may be required depending on the role or employer requirements. Where applicable, additional fees may apply.
The order of assessments may vary slightly depending on whether a drug and alcohol test is also being carried out at the same appointment.
How long does a safety critical medical last?
A safety critical medical appointment typically takes between 30 and 45 minutes, depending on the assessment requirements and whether a drug and alcohol test is included.
Where additional checks are required in line with employer or industry standards, the appointment may take longer.
How do I pass a safety critical medical?
To pass a safety critical medical, you must meet the medical fitness standards required for the specific role you are undertaking.
If you meet the required standards, you will receive certification confirming your fitness for work. If any concerns are identified during the assessment, further medical information may be requested from your GP or specialist. In some cases, your results may be reviewed by a Responsible Occupational Physician before a final decision is made.
The outcome of the assessment is based solely on whether you meet the safety-critical medical standards applicable to your role.
