Frequently asked questions
The definition used by the International Occupational Hygiene Association (IOHA) is: "Occupational Hygiene is the discipline of anticipating, recognising, evaluating and controlling health hazards in the working environment with the objective of protecting worker health and well-being and safeguarding the community at large."
Education, training and experience are all important aspects of an occupational hygienist’s career. Education can be obtained through formal undergraduate or postgraduate degrees, training can be gained by taking specialised courses, and experience can be achieved by working in the field.
There are many excellent occupational safety and health certificate, diploma and degree courses. Most are not accredited by BOHS. Many courses and webinars help develop competence, but if UK or US based they are unlikely to have irish legal rquirements. Knowledge of Irish Legislation is essential for those practicing in Ireland.
The following univeristy courses are accreditted by BOHS.
MSc Occupational Hygiene
MSc Safety, Health and Environment
BSc (Hons) Occupational Safety, Health and Environment (with an occupational hygiene related project) (Certificate only)
MSc Occupational Hygiene
Postgraduate Diploma Occupational Hygiene (Certificate only)
MSc/HDip Occupational and Environmental Health & Safety (Full time/Part-time options)

It is the employers responsibility under Health and Safety legislation to ensure they appoint a competent person to carry out any occupational hygiene services.
A person is deemed to be a competent person where, having regard to the task he or she is required to perform and taking account of the size or hazards (or both of them) of the undertaking or establishment in which he or she undertakes work, the person possesses sufficient training, experience and knowledge appropriate to the nature of the work to be undertaken.

How to achieve best outcomes for occupational hygiene monitoring in your business.

When selecting an occupational hygiene service provider, there are some key considerations:
do they have evidence of relevant competency, such as formal qualifications and training (e.g. the BOHS Certificate of Operational Competence or the Diploma of Professional Competence)?
do they have practical experience related to your industry, or processes?
can they explain to you why they are competent to advise you on this problem?
do they have the resources to complete the work within the required timescale?
can they provide references for completed work on similar projects?
are they a member of a relevant professional body e.g. BOHS (British Occupational Hygiene Society), FAAM (Faculty of Asbestos Assessment and Management), IOA (Institute of Acoustics).
The word hygiene is derived from the name of the Greek goddess of health Hygieia. She was the daughter of Asklepius and the sister of Panacea. While her father and sister were associated with the treatment of diseases, Hygieia is associated with taking care of good health and disease prevention.
None really, Industrial Hygiene is the terminology used in the USA.
In some ways the term Occupational is a better description as health risks occur in all places that people work such as offices, shops, hospitals and farms, not just in places you would think of as industrial.

The UK Methods of Determination of Hazardous Substances (MDHS 25/4 )can be used for the determination of time-weighted average concentrations of organic isocyanates in workplace atmospheres. The method requires the use of a glass impinger containing 1-(2-methoxyphenyl)piperazine (1,2-MP) absorbing solution backed with a filter impregnated with 1,2-MP reagent (isocyanate aerosols) or alternatively a single filter impregnated with the 1,2-MP reagent (isocyanate vapour).
However, “1-(2-methoxyphenyl)piperazine” is classed as a controlled substance in Ireland under Schedule 1, of the Misuse of Drugs Regulations. Any establishment that intends to possess this controlled substance on site would require a controlled drug annual licence, issued by the HPRA on behalf of the Department of Health, in order to do so. In addition, any establishment that intends to import/export this controlled substance into/out of Ireland would require a controlled drug import and/or export licence, per consignment, in order to import/export this controlled substance. See www.hpra.ie.
The British Occupational Hygiene Society Group Authority license only applies to members of the Faculty of Occupational Hygiene and does not apply to use in the Republic of Ireland or in Northern Ireland.
Alternative sampling methods are available for isocyanates, however, they have drawbacks.
They typically fail to measure the total reactive isocyanate group (TRIG) concentration necessary for direct comparison with the OEL.
It is important that any method captures both the aerosol and vapour phases.
In addition, there is evidence that dermal exposures can lead to sensitization. Air monitoring will not measure this exposure so the risk will be underestimated.
Surface monitoring techniques can change colour in presence of some isocyanates – this only indicates presence, not amount.
Based on all of these, air sampling for isocyanates is unlikely to provide reliable, usable valuable data. An alternative is to use biological monitoring.
