Health Care Work:

Health Care workers are exposed to many job hazards. The Health sector is one of the largest employers in the country and has a substantial proportion of female staff.  Health care workers face a wide range of hazards in the job including needle stick injuries, back injuries, latex allergy, violence and stress.

Most Health Care organizations now have a range of policies and standard operating procedures to help them address hazards in the health care sector.  We can advise you with regards to an appropriate policy and procedure for your workplace.

Preventable infectious illness: Effective vaccines are now available for a wide range of infectious illness which are common in the health care sector including influenza, hepatitis B, hepatitis A, VZV (chicken pox), MMR and others.

Tuberculosis: There is an increased risk of Tuberculosis in parts of the Health Care sector.  We advise on compliance with the latest guidelines on prevention of TB and BCG vaccination for at risk workers.

Stress: This is an increasing problem in the health care sector. Many organisations are now utilizing stress audits and stress management programmes as a means of addressing the problem. We can advise you on all aspects of stress management for your organisation.

Offshore (Oil and Gas UK):

The UK Offshore industry requires that all persons working offshore be certified as medically fit to do so.  Oil and Gas UK (OGUK) publish medical guidelines setting out what is considered to be good practice regarding the assessment of the health of persons working or intending to work offshore, and guidance on the implications of various medical conditions on fitness to do so.  All assessments under these guidelines must include a personal examination by examining physician who is approved by OGUK.  EHA Limerick has doctors who are on the OGUK Register of Examining Doctors.

The OGUK Medical Certificate (unrestricted) is accepted by the Norwegian and Dutch authorities for Offshore work in their sectors.

At EHA Limerick we also work closely with the National Maritime College of Ireland


Irish law requires a valid certificate of medical fitness before a person can be employed as a diver or is permitted to dive in any diving operation. The certificate may only be issued after a medical examination by a medical examiner of divers who is approved by the Health and Safety Authority in Ireland.  Dr Brian Gallagher, at our sister company CHI in Cork, is on the HSA list of approved doctors to perform diving medicals.

Detailed information on the Diving Medical can be found in the HSA document ‘Guidance on the Medical Assessment of Divers’ on the HSA website.

Fitness to dive medicals must be completed at least annually or more frequently if specified by the medical examiner of divers. The Authority and the Health and Safety Executive (United Kingdom) have a mutual recognition agreement of doctors approved to carry out diving medical examinations and diving medical testing.


The Merchant Shipping (Medical Examinations) Regulations 2014 make it a legal requirement for any seafarer, as defined in the Regulations, to hold a valid certificate attesting to their medical fitness for the work for which they are employed. This is to reduce risks to other crew members and for the safe operation of the ship, as well as to safeguard their personal health and safety.

Approved Doctors are required to determine a seafarer’s fitness by reference to the statutory medical and eyesight standards set out in the Regulations

Medical fitness certificates are issued by an Approved Doctor in accordance with the provisions of the Regulations.

The Seafarer ENG11 Medical can only be performed by a doctor appointed by the Maritime Safety Directorate and both Brian Gallagher and Dr Martin Hogan at our sister company CHI in Cork, are approved for this purpose.

Shoulder width measurement

Dr Brian Gallagher, at our sister company CHI in Cork, is licenced to perform the “bi-deltoid shoulder width measurement” for travel in helicopters in the UK.  This is a Civil Aviation Authority requirement in the UK to allocate seating on helicopters according to shoulder width measurement.  It is separate from and not a requirement for the OGUK Medical although in practice in future they are likely to be performed at the same time.  A separate shoulder width measurement certificate will be issued on completion of the test.
