Occupational (or "industrial" in the U.S.) hygiene is generally defined as the art and science dedicated to the anticipation, recognition, evaluation, communication and control of environmental stressors in, or arising from, the workplace that may result in injury, illness, impairment, or affect the well being of workers and members of the community. These stressors are divided into the categories biological, chemical, physical, ergonomic and psychosocial. The British Occupational Hygiene Society (BOHS) define that "occupational hygiene is about the prevention of ill-health from work, through recognizing, evaluating and controlling the risks". The International Occupational Hygiene Association (IOHA) refers to occupational hygiene as the discipline of anticipating, recognizing, 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.
The term "occupational hygiene" (used in the UK and Commonwealth countries as well as much of Europe) is synonymous with industrial hygiene (used in the US, Latin America, and other countries that received initial technical support or training from US sources). The term "industrial hygiene" traditionally stems from industries with construction, mining or manufacturing and "occupational hygiene" refers to all types of industry such as those listed for "industrial hygiene" as well as financial and support services industries and refers to "work", "workplace" and "place of work" in general. Environmental hygiene addresses similar issues to occupational hygiene, but is likely to be about broad industry or broad issues effecting the local community, broader society, region or country.
The profession of occupational hygiene uses strict and rigorous scientific methodology and often requires professional experience in determining the potential for hazard, exposures or risk in workplace and environmental studies. This aspect of occupational hygiene is often referred to as the "art" of occupational hygiene and is used in a similar sense to the "art" of medicine. In fact "occupational hygiene" is both an aspect of preventative medicine, in that its goal is to prevent industrial disease, and risk management, risk assessment and industrial safety, in that it also seeks "safe" systems, procedures or methods to be applied in the workplace or to the environment.
The Social Role of Occupational Hygiene
Occupational hygienists have been involved historically with changing the perception of society about the nature and extent of hazards in the workplace. Many occupational hygienists work day-to-day with industrial situations that require control or improvement to the workplace situation however larger social issues affecting whole industries have occurred in the past e.g. since 1900, asbestos exposures that have affected the lives of tens of thousands of people.
More recent issues affecting broader society are, for example in 1976, legionnaires' disease or legionellosis. More recently again in the 1990s radon and in the 2000s the effects of mould from indoor air quality situations in the home and at work. In the later part of the 2000s concern has been raised about the health effects of nanoparticles.
Many of these issues have required the coordination over a number of years of a number of medical and para professionals in detecting and then characterizing the nature of the issue, both in terms of the hazard and in terms of the risk to the workplace and ultimately to society. This has involved occupational hygienists in research, collection of data and to develop suitable and satisfactory control methodologies.
Workplace Assessment Methods
Although there are many aspects to occupational hygiene work the most known and sought after is in determining or estimating potential or actual exposures to hazards. Several methods can be applied in assessing the workplace or environment for exposure to a known or suspected hazard. Occupational hygienists do not rely on the accuracy of the equipment or method used but in knowing with certainty and precision the limits of the equipment or method being used and the error or variance given by using that particular equipment or method.
A traditional method applied by occupational hygienists to initially survey a workplace or environment is used to determine both the types and possible exposures from hazards (e.g. noise, chemicals, radiation). The walk-through survey can be targeted or limited to particular hazards such as silica dust, or noise, to focus attention on control of those hazards. A full walk-through survey is frequently used to provide information on establishing a framework for future investigations, prioritizing hazards, determining the requirements for measurement and establishing some immediate control of potential exposures.
Electronic Hazard Survey Equipment
An occupational hygienist may use one or a number of commercially available electronic measuring devices to measure noise, vibration, ionizing and non-ionizing radiation, dust, solvents, gases, et cetera. Each device is often specifically designed to measure a specific or particular type of contaminant. Such devices are often subject to multiple interferences. Electronic devices need to be calibrated before and after use to ensure the accuracy of the measurements taken and often require a system of certifying the precision of the instrument.
Nuisance dust is considered to be the total dust in air including inhalable and respirable fractions.
Various dust sampling methods exist that are internationally recognised. Inhalable dust is determined using the modern equivalent of the Institute of Occupational Medicine (IOM) MRE 113A monitor (see section on workplace exposure, measurement & modelling). Inhalable dust is considered to be dust of less than 100 micrometers aerodynamic equivalent diameter (AED) that enters through the nose and or mouth. See Lungs
Respirable dust is sampled using a cyclone dust sampler design to sample for a specific fraction of dust AED at a set flow rate. The respirable dust fraction is dust that enters the 'deep lung' and is considered to be less than 10 micrometers AED.
Nuisance, inhalable and respirable dust fractions are all sampled using a constant volumetric pump for a specific sampling period. By knowing the mass of the sample collected and the volume of air sampled a concentration for the fraction sampled can be given in milligrams (mg) per metre cubed (m3). From such samples the amount of inhalable or reespirable dust can be determined and compared to the relevant occupational exposure limits.
By use of inhalable, respirable or other suitable sampler (7 hole, 5 hole, et cetera) these dust sampling methods can also used to determine metal exposure in the air. This requires collection of the sample on a methyl-cellulose ester (MCE) filter and acid digestion of the collection media in the laboratory followed by measuring metal concentration though an atomic absorption (or emission) spectrophotometery. Both the UK HSE  and NIOSH NMAM  have specific methodologies for a broad range of metals in air found in industrial processing (smelting, foundries, et cetera).
A further method exists for the determination of asbestos, fibreglass, synthetic mineral fibre and ceramic mineral fibre dust in air. This is the membrane filter method (MFM) and requires the collection of the dust on a grided filter for estimation of exposure by the counting of 'conforming' fibres in 100 fields through a microscope. Results are quantified on the basis of number of fibres per millilitre of air (f/ml). Many countries strictly regulate the methodology applied to the MFM.
Two types of chemically absorbent tubes are used to sample for a wide range of chemical substances. Traditionally a chemical absorbent 'tube' (a glass or stainless steel tube of between 2 and 10 mm internal diameter) filled with very fine absorbent silica (hydophylic) or carbon, such as coconut charcoal (lypophylic), is used in a sampling line where air is drawn through the absorbent material for between 4 hours (minimum workplace sample) to 24 hours (environmental sample) period. The hydrophylic material readily absorbs water soluble chemical and the lypophylic material absorbs non water soluble materials. The absorbent material is then chemically or physically extracted and measurements performed using various gas chromatograph or mass spectometry methods. These absorbent tube methods have the advantage of being usable for a wide range of potential contaminates. However, they are relatively expensive methods, time consuming and require significant expertise in sampling and chemical analysis. A frequent complaint of workers is in having to wear the sampling pump (up to 1 kg) for several days of work to provide adequate data for the required statistical certainty determination of the exposure.
In the last few decades advances have being made in 'passive' badge technology. These samplers can now be purchased to measure one chemical (e.g. formaldehyde) or a chemical type (e.g. ketones) or a broad spectrum of chemicals (e.g. solvents). They are relatively easy to set up and use. However, considerable cost can still be incurred in analysis of the 'badge'. They weigh 20 to 30 grams and workers do not complain about their presence. Unfortunately 'badges' may not exist for all types of workplace sampling that may be required and the charcoal or silica method may sometimes have to be applied.
From the sampling method results are expressed in milligrams per cubic meter (mg/m3) or parts per million (PPM) and compared to the relevant occupational exposure limits.
It is a critical part of the exposure determination that the method of sampling for the specific contaminate exposure is directly linked to the exposure standard used. Many countries regulate both the exposure standard, the method used to determine the exposure and the methods to be used for chemical or other analysis of the samples collected.
The occupational hygienist may be involved with the assessment and control of physical, chemical, biological or environmental hazards in the workplace or community that could cause injury or disease. Physical hazards may include noise, temperature extremes, illumination extremes, ionizing or non-ionizing radiation, and ergonomics. Chemical hazards related to dangerous goods or hazardous substances are frequently investigated by occupational hygienists. Other related areas including indoor air quality (IAQ) and safety may also receive the attention of the occupational hygienist. Biological hazards may stem from the potential for legionella exposure at work or the investigation of biological injury or effects at work, such as dermatitis may be investigated.
As part of the investigation process, the occupational hygienist may be called upon to communicate effectively regarding the nature of the hazard, the potential for risk, and the appropriate methods of control. Appropriate controls are selected from the hierarchy of control: by elimination, substitution, engineering, administration and personal protective equipment (PPE) in order to control the hazard or eliminate the risk. Such controls may involve recommendations as simple as appropriate PPE such as a 'basic' particulate dust mask to occasionally designing dust extraction ventilation systems, work places or management systems in order to manage people and programs for the preservation of health and well-being of those who enter a workplace.
The basis of the technical knowledge of occupational hygiene is from competent training in the following areas of science and management.
- Basic Sciences (Biology, Chemistry, Mathematics (Statistics), Physics);
- Occupational Diseases (Illness, injury and health surveillance (biostatistics, epidemiology, toxicology));
- Health Hazards (Biological, Chemical and Physical hazards, Ergonomics and Human Factors);
- Working Environments (Mining, Industrial, Manufacturing, transport and storage, service industries and offices);
- Programme Management Principles (professional and business ethics, work site and incident investigation methods, exposure guidelines, Occupational exposure limits, jurisdictional based regulations, hazard identification, risk assessment and risk communication, data management, fire evacuation and other emergency responses);
- Sampling, measurement and evaluation practices (instrumentation, sampling protocols, methods or techniques, analytical chemistry);
- Hazard Controls (elimination, substitution, engineering, administrative, PPE and Air Conditioning and Extraction Ventilation);
- Environment (air pollution, hazardous waste).
However, it is not rote knowledge that identifies a competent occupational hygienist. There is an "art" to applying the technical principles in a manner that provides a reasonable solution for workplace and environmental issues. In effect an experienced "mentor", who has experience in occupational hygiene is required to show a new occupational hygienist how to apply the learned scientific and management knowledge in the workplace and to the environment issue to satisfactorily resolve the problem.
To be a professional occupational hygienist, experience in as wide a practice as possible is required to demonstrate knowledge in areas of occupational hygiene. This is difficult for "specialists" or those who practice in narrow subject areas. Limiting experience to individual subject like asbestos remediation, confined spaces, indoor air quality, or lead abatement, or learning only through a textbook or “review course” can be a disadvantage when required to demonstrate competence in other areas of occupational hygiene.
Information presented in Wikipedia can be considered to be only an outline of the requirements for professional occupational hygiene training. This is because the actual requirements in any country, state or region may vary due to educational resources available, industry demand or regulatory mandated requirements.
During 2010, the Occupational Hygiene Training Association (OHTA) through sponsorship provided by the IOHA initiated a training scheme for those with an interest in or those requiring training in occupational hygiene. These training modules can be downloaded and used freely. The available subject modules (Basic Principles in Occupational Hygiene, Health Effects of Hazardous Substances, Measurement of Hazardous Substances, Thermal Environment, Noise, Asbestos, Control, Ergonomics) are aimed at the ‘foundation’ and ‘intermediate’ levels in Occupational Hygiene. Although the modules can be used freely without supervision attendance at an accredited training course is encouraged. These training modules are available from OH Learning.com
Academic programs offering industrial hygiene Bachelors or Masters degrees in United States may apply to the Accreditation Board for Engineering and Technology (ABET) to have their program accredited. As of October 1, 2006, 27 institutions have accredited their industrial hygiene programs. Accreditation is not available for Doctoral programs.
The International Occupational Hygiene Association was formed in 1987. Its membership are the national professional associations, now numbering more than 20 organizations and representing over 20,000 occupational hygienists worldwide.
National professional societies include the following (in alphabetical order):
- American Conference of Governmental Industrial Hygienists (ACGIH)
- Formed in 27 June 1938 as the National Conference of Governmental Industrial Hygienists, renamed ACGIH in 1946. This organization was originally conceived as a gathering of the governmental organizations that employed industrial hygienists and membership was limited to two from each organization. From 1946, all industrial hygiene personnel employed by government agencies and educational institutions were eligible for membership. Today, membership is open to all practitioners in industrial hygiene, occupational health, environmental health, and safety.
- American Industrial Hygiene Association (AIHA)
- Founded in 1939, AIHA has more than 75 local sections and 11,800 members, making it the largest of the national professional associations.
- Australian Institute of Occupational Hygienists(AIOH)
- The AIOH was formed in 1980 as a forum for scientific meetings between scientific officers (now termed occupational hygienists) involved in government work between Commonwealth, State and Territory Governments in Australia. From the outset membership of AIOH was open to all those with an interest in occupational or environmental hygiene or a scientific interest in health and safety. Current membership includes approximately 600 members with Associate, Provisional, Full and Fellow grades of membership. Provisional, full and fellow membership levels required set qualifications and professional experience criteria to be achieved.
- Association of Professional Industrial Hygienists
- The Association of Professional Industrial Hygienists, Inc. (APIH) was established in 1994 to offer credentialing to industrial hygienists who meet the education and experience requirements found in Tennessee Code Annotated, Title 62, Chapter 40. APIH adopted the Tennessee Code as its basis for credentialing because it was the first legal definition in the United States of an industrial hygienist in terms of education and experience. The APIH Registration Committee investigates and verifies, through electronic means or correspondence, both educational and experience accomplishments claimed by each applicant for registration. The Committee determines the appropriate level of registration, Registered Industrial Hygienist or Registered Professional Industrial Hygienist, and then authorizes the registration certificate to be issued.
- Belgian Society for Occupational Hygiene
- Brazilian Association of Occupational Hygienists
- Established in August 1994

In 2005, the Australian Institute of Occupational Hygiene (AIOH) has accredited professional occupational hygienist through a certification scheme. Occupational Hygienists in Australian certified through this scheme are entitled to use the phrase Certified Occupational Hygienist (COH) as part of their qualifications.
United States of America
Practitioners who successfully meet specific education and work-experience requirements, and pass a written examination administered by the American Board of Industrial Hygiene (ABIH) are authorized to use the term Certified Industrial Hygienist (CIH) or Certified Associate Industrial Hygienist (CAIH). Both of these terms have been codified into law in many states in the United States in order to identify minimum qualifications of individuals having oversight over certain activities that may affect employee and general public health.
After the initial certification, the CIH or CAIH maintains their certification by meeting on-going requirements for ethical behavior, education, and professional activities (e.g., active practice, technical committees, publishing, teaching).
ABIH certification examinations are offered during a spring and fall testing window each year at more than 400 locations worldwide.
The CIH designation is the most well known and recognized industrial hygiene designation throughout the world. There are approximately 6600 CIHs in the world making ABIH the largest industrial hygiene certification firm. The CAIH certification program was discontinued in 2006. Those who were certified as a CAIH retain their certification through ongoing certification maintenance. People who are currently certified by the ABIH can be found in a public roster.
The ABIH is a recognized certification board by the International Occupational Hygiene Association (IOHA). The CIH certification has been accredited internationally by the International Organization for Standardization/International Electrotechnical Commission (ISO/IEC 17024) (see ANSI). In the United States, the CIH has been accredited by the Council of Engineering and Scientific Specialty Boards [CESB].
In Canada, a practitioner who successfully completes a written and an interview administered by the Canadian Registration Board of Occupational Hygienists can be recognized as a Registered Occupational Hygienist (ROH) or Registered Occupational Hygiene Technician (ROHT). There is also designation to be recognized as a Canadian Registered Safety Professional (CRSP).
The Faculty of Occupational Hygiene, part of the British Occupational Hygiene Society, represents the interests of professional occupational hygienists.
Membership of the Faculty of Occupational Hygiene is confined to BOHS members who hold a recognized professional qualification in occupational hygiene.
There are three grades of Faculty membership:
- Licentiate (LFOH) holders will have obtained the BOHS Certificate of Operational Competence in Occupational Hygiene and have at least three years’ practical experience in the field.
- Members (MFOH) are normally holders of the Diploma of Professional Competence in Occupational Hygiene and have at least five years’ experience at a senior level.
- Fellows (FFOH) are senior members of the profession who have made a distinct contribution to the advancement of occupational hygiene.
All Faculty members participate in a Continuous Professional Development (CPD) scheme designed to maintain a high level of current awareness and knowledge in occupational hygiene.
Examples of occupational hygiene
- See the Related Journals listed above for many examples of the science underlying occupational hygiene and its practical application
- Analysis of occupational hygiene effects can lead to worker protection plans. For example it is common in high noise environments to use earplugs or earmuffs. These are available over a range of applications, effectiveness and quality.
- Occupational Hygienists are among the experts planning the controls to protect against exposure in the event of a flu pandemic.
- Occupational/Industrial Hygienists are responsible for monitoring and testing the air for hazardous contaminants that can lead to potential worker illness and sometimes death.
Examples of occupational hygiene careers
- Compliance officer on behalf of regulatory agency
- Professional working on behalf of company for the protection of the workforce
- Consultant working on behalf of companies
- Researcher performing laboratory or field occupational hygiene work
It is difficult to create a comprehensive list of references for Occupational Hygiene. Firstly, a list is required for the practices and methodologies involved with the profession of Occupational Hygiene. This list alone can be quite extensive. Secondly, a list of references for each subject area, issue or problem to be resolved from an Occupational Hygiene stand point is required and this information is to be applied to each workplace within each regulatory framework. More importantly the list of references will change due to both changes in technology and changes in requirements for Regulatory compliance. The reference list below may help to get started in self-educating, researching a problem or resolving an issue.
