What is Industrial Hygiene?
Industrial hygiene is the science of anticipating, recognizing, evaluating, and controlling workplace
conditions that may cause workers' injury or illness. Industrial hygienists use environmental monitoring and
analytical methods to detect the extent of worker exposure and employ engineering, work practice controls, and
other methods to control potential health hazards.
There has been an awareness of industrial hygiene since antiquity. The environment and its relation to
worker health was recognized as early as the fourth century BC when Hippocrates noted lead toxicity in the mining
industry. In the first century AD, Pliny the Elder, a Roman scholar, perceived health risks to those working with
zinc and sulfur. He devised a face mask made from an animal bladder to protect workers from exposure to dust and
lead fumes. In the second century AD, the Greek physician, Galen, accurately described the pathology of lead
poisoning and also recognized the hazardous exposures of copper miners to acid mists.
In the Middle Ages, guilds worked at assisting sick workers and their families. In 1556 the German scholar,
Agricola, advanced the science of industrial hygiene even further when, in his book De Re Metallica, he described
the diseases of miners and prescribed preventive measures. The book included suggestions for mine ventilation and
worker protection, discussed mining accidents, and described diseases associated with mining occupations such as
silicosis.
Industrial hygiene gained further respectability in 1700 when Bernardo Ramazzini, known as the "father of
industrial medicine," published in Italy the first comprehensive book on industrial medicine, De Morbis Artificum
Diatriba (The Diseases of Workmen). The book contained accurate descriptions of the occupational diseases of most
of the workers of his time. Ramazzini greatly affected the future of industrial hygiene because he asserted that
occupational diseases should be studied in the work environment rather than in hospital wards.
Industrial hygiene received another major boost in 1743 when Ulrich Ellenborg published a pamphlet on
occupational diseases and injuries among gold miners. Ellenborg also wrote about the toxicity of carbon monoxide,
mercury, lead, and nitric acid.
In England in the 18th century, Percival Pott, as a result of his findings on the insidious effects of soot
on chimney sweepers, was a major force in getting the British Parliament to pass the Chimney-Sweepers Act of 1788.
The passage of the English Factory Acts beginning in 1833 marked the first effective legislative acts in the field
of industrial safety. The Acts, however, were intended to provide compensation for accidents rather than to control
their causes. Later, various other European nations developed workers' compensation acts, which stimulated the
adoption of increased factory safety precautions and the establishment of medical services within industrial
plants.
In the early 20th century in the U. S., Dr. Alice Hamilton, led efforts to improve industrial hygiene. She
observed industrial conditions first hand and startled mine owners, factory managers, and state officials with
evidence that there was a correlation between worker illness and their exposure to toxins. She also presented
definitive proposals for eliminating unhealthful working conditions.
At about the same time, U.S. federal and state agencies began investigating health conditions in industry.
In 1908, the public's awareness of occupationally related diseases stimulated the passage of compensation acts
for certain civil employees. States passed the first workers' compensation laws in 1911. And in 1913, the New York
Department of Labor and the Ohio Department of Health established the first state industrial hygiene programs. All
states enacted such legislation by 1948. In most states, there is some compensation coverage for workers contracting
occupational diseases.
The U.S. Congress has passed three landmark pieces of legislation relating to safeguarding workers' health:
(1) the Metal and Nonmetallic Mines Safety Act of 1966, (2) the Federal Coal Mine Safety and Health Act of 1969,
and (3) the Occupational Safety and Health Act of 1970 (Act). Today, nearly every employer is required to implement
the elements of an industrial hygiene and safety, occupational health, or hazard communication program and to be
responsive to the Occupational Safety and Health Administration (OSHA) and the Act and its regulations.
How Are OSHA and Industrial Hygiene Related?
Under the Act, OSHA develops and sets mandatory occupational safety and health requirements applicable to
the more than 6 million workplaces in the U.S. OSHA relies on, among many others, industrial hygienists to
evaluate jobs for potential health hazards. Developing and setting mandatory occupational safety and health
standards involves determining the extent of employee exposure to hazards and deciding what is needed to control
these hazards, thereby protecting the workers. Industrial hygienists, or IHs, are trained to anticipate, recognize,
evaluate, and recommend controls for environmental and physical hazards that can affect the health and well-being
of workers. More than 40 percent of the OSHA compliance officers who inspect America's workplaces are industrial
hygienists. Industrial hygienists also play a major role in developing and issuing OSHA standards to protect
workers from health hazards associated with toxic chemicals, biological hazards, and harmful physical agents. They
also provide technical assistance and support to the agency's national and regional offices. OSHA also employs
industrial hygienists who assist in setting up field enforcement procedures, and who issue technical interpretations
of OSHA regulations and standards. Industrial hygienists analyze, identify, and measure workplace hazards or
stressors that can cause sickness, impaired health, or significant discomfort in workers through chemical, physical,
ergonomic, or biological exposures. Two roles of the OSHA industrial hygienist are to spot those conditions and help
eliminate or control them through appropriate measures.
What is a Worksite Analysis?
A worksite analysis is an essential first step that helps an industrial hygienist determine what jobs and
work stations are the sources of potential problems. During the worksite analysis, the industrial hygienist measures
and identifies exposures, problem tasks, and risks. The most effective worksite analyses include all jobs,
operations, and work activities. The industrial hygienist inspects, researches, or analyzes how the particular
chemicals or physical hazards at that worksite affect worker health. If a situation hazardous to health is
discovered, the industrial hygienist recommends the appropriate corrective actions.
How do IH's Recognize and Control Hazards?
Industrial hygienists recognize that engineering, work practice, and administrative controls are the primary
means of reducing employee exposure to occupational hazards. Engineering controls minimize employee exposure by
either reducing or removing the hazard at the source or isolating the worker from the hazards.
Engineering controls include eliminating toxic chemicals and replacing harmful toxic materials with less
hazardous ones, enclosing work processes or confining work operations, and installing general and local ventilation
systems.
Work practice controls alter the manner in which a task is performed. Some fundamental and easily implemented
work practice controls include (1) following proper procedures that minimize exposures while operating production
and control equipment; (2) inspecting and maintaining process and control equipment on a regular basis; (3)
implementing good house-keeping procedures; (4) providing good supervision and (5) mandating that eating, drinking,
smoking, chewing tobacco or gum, and applying cosmetics in regulated areas be prohibited.
Administrative controls include controlling employees' exposure by scheduling production and workers' tasks,
or both, in ways that minimize exposure levels. For example, the employer might schedule operations with the highest
exposure potential during periods when the fewest employees are present.
When effective work practices and/or engineering controls are not feasible to achieve the permissible exposure
limit, or while such controls are being instituted, and in emergencies, appropriate respiratory equipment must be
used. In addition, personal protective equipment such as gloves, safety goggles, helmets, safety shoes, and
protective clothing may also be required. To be effective, personal protective equipment must be individually
selected, properly fitted and periodically refitted; conscientiously and properly worn; regularly maintained;
and replaced as necessary.
What Are Some Examples of Job Hazards?
To be effective in recognizing and evaluating on-the-job hazards and recommending controls, industrial
hygienists must be familiar with the hazards' characteristics. Major job risks can include air contaminants, and
chemical, biological, physical, and ergonomic hazards.
Air Contaminants
These are commonly classified as either particulate or gas and vapor contaminants. The most common particulate
contaminants include dusts, fumes, mists, aerosols, and fibers. Dusts are solid particles that are formed or
generated from solid organic or inorganic materials by reducing their size through mechanical processes such as
crushing, grinding, drilling, abrading or blasting.
Fumes are formed when material from a volatilized solid condenses in cool air. In most cases, the solid
particles resulting from the condensation react with air to form an oxide.
The term mist is applied to a finely divided liquid suspended in the atmosphere. Mists are generated by
liquids condensing from a vapor back to a liquid or by breaking up a liquid into a dispersed state such as by
splashing, foaming or atomizing. Aerosols are also a form of a mist characterized by highly respirable, minute
liquid particles.
Fibers are solid particles whose length is several times greater than their diameter.
Gases are formless fluids that expand to occupy the space or enclosure in which they are confined. Examples
are welding gases such as acetylene, nitrogen, helium, and argon; and carbon monoxide generated from the operation
of internal combustion engines or by its use as a reducing gas in a heat treating operation. Another example is
hydrogen sulfide which is formed wherever there is decomposition of materials containing sulfur under reducing
conditions.
Liquids change into vapors and mix with the surrounding atmosphere through evaporation. Vapors are the
volatile form of substances that are normally in a solid or liquid state at room temperature and pressure. Vapors
are the gaseous form of substances which are normally in the solid or liquid state at room temperature and pressure.
They are formed by evaporation from a liquid or solid and can be found where parts cleaning and painting takes place
and where solvents are used.
Chemical Hazards
Harmful chemical compounds in the form of solids, liquids, gases, mists, dusts, fumes, and vapors exert toxic
effects by inhalation (breathing), absorption (through direct contact with the skin), or ingestion (eating or
drinking). Airborne chemical hazards exist as concentrations of mists, vapors, gases, fumes, or solids. Some are
toxic through inhalation and some of them irritate the skin on contact; some can be toxic by absorption through the
skin or through ingestion, and some are corrosive to living tissue.
The degree of worker risk from exposure to any given substance depends on the nature and potency of the
toxic effects and the magnitude and duration of exposure.
Information on the risk to workers from chemical hazards can be obtained from the Material Safety Data Sheet
(MSDS) that OSHA'S Hazard Communication Standard requires be supplied by the manufacturer or importer to the
purchaser of all hazardous materials. The MSDS is a summary of the important health, safety, and toxicological
information on the chemical or the mixture's ingredients. Other provisions of the Hazard Communication Standard
require that all containers of hazardous substances in the workplace have appropriate warning and identification
labels.
Biological Hazards
These include bacteria, viruses, fungi, and other living organisms that can cause acute and chronic infections
by entering the body either directly or through breaks in the skin. Occupations that deal with plants or animals
or their products or with food and food processing may expose workers to biological hazards. Laboratory and medical
personnel also can be exposed to biological hazards. Any occupations that result in contact with bodily fluids pose
a risk to workers from biological hazards.
In occupations where animals are involved, biological hazards are dealt with by preventing and controlling
diseases in the animal population as well as proper care and handling of infected animals. Also, effective personal
hygiene, particularly proper attention to minor cuts and scratches, especially those on the hands and forearms,
helps keep worker risks to a minimum.
In occupations where there is potential exposure to biological hazards, workers should practice proper
personal hygiene, particularly hand washing. Hospitals should provide proper ventilation, proper personal protective
equipment such as gloves and respirators, adequate infectious waste disposal systems, and appropriate controls
including isolation in instances of particularly contagious diseases such as tuberculosis.
Physical Hazards
These include excessive levels of ionizing and nonionizing electromagnetic radiation, noise, vibration,
illumination, and temperature.
In occupations where there is exposure to ionizing radiation, time, distance, and shielding are important
tools in ensuring worker safety. Danger from radiation increases with the amount of time one is exposed to it;
hence, the shorter the time of exposure the smaller the radiation danger.
Distance also is a valuable tool in controlling exposure to both ionizing and non-ionizing radiation.
Radiation levels from some sources can be estimated by comparing the squares of the distances between the worker and
the source. For example, at a reference point of 10 feet from a source, the radiation is 1/100 of the intensity at
1 foot from the source.
Shielding also is a way to protect against radiation. The greater the protective mass between a radioactive
source and the worker, the lower the radiation exposure.
Nonionizing radiation also is dealt with by shielding workers from the source. Sometimes limiting exposure
times to nonionizing radiation or increasing the distance is not effective. Laser radiation, for example, cannot be
controlled effectively by imposing time limits. An exposure can be hazardous that is faster than the blinking of an
eye. Increasing the distance from a laser source may require miles before the energy level reaches a point where the
exposure would not be harmful.
Noise, another significant physical hazard, can be controlled by various measures. Noise can be reduced by
installing equipment and systems that have been engineered, designed, and built to operate quietly; by enclosing or
shielding noisy equipment; by making certain that equipment is in good repair and properly maintained with all worn
or unbalanced parts replaced; by mounting noisy equipment on special mounts to reduce vibration; and by installing
silencers, mufflers, or baffles.
Substituting quiet work methods for noisy ones is another significant way to reduce noise, for example,
welding parts rather than riveting them. Also, treating floors, ceilings, and walls with acoustical material can
reduce reflected or reverberant noise. In addition, erecting sound barriers at adjacent work stations around
noisy operations will reduce worker exposure to noise generated at adjacent work stations.
It is also possible to reduce noise exposure by increasing the distance between the source and the receiver,
by isolating workers in acoustical booths, limiting workers' exposure time to noise, and by providing hearing
protection. OSHA requires that workers in noisy surroundings be periodically tested as a precaution against hearing
loss.
Another physical hazard, radiant heat exposure in factories such as steel mills, can be controlled by
installing reflective shields and by providing protective clothing.
Ergonomic Hazards
The science of ergonomics studies and evaluates a full range of tasks including, but not limited to, lifting,
holding, pushing, walking, and reaching. Many ergonomic problems result from technological changes such as increased
assembly line speeds, adding specialized tasks, and increased repetition; some problems arise from poorly designed
job tasks. Any of those conditions can cause ergonomic hazards such as excessive vibration and noise, eye strain,
repetitive motion, and heavy lifting problems. Improperly designed tools or work areas also can be ergonomic
hazards. Repetitive motions or repeated shocks over prolonged periods of time as in jobs involving sorting,
assembling, and data entry can often cause irritation and inflammation of the tendon sheath of the hands and
arms, a condition known as carpal tunnel syndrome.
Ergonomic hazards are avoided primarily by the effective design of a job or jobsite and better designed tools
or equipment that meet workers' needs in terms of physical environment and job tasks. Through thorough worksite
analyses, employers can set up procedures to correct or control ergonomic hazards by using the appropriate
engineering controls (e.g., designing or re-designing work stations, lighting, tools, and equipment); teaching
correct work practices (e.g., proper lifting methods); employing proper administrative controls (e.g., shifting
workers among several different tasks, reducing production demand, and increasing rest breaks); and, if neces-
sary, providing and mandating personal protective equipment. Evaluating working conditions from an ergonomics
standpoint involves looking at the total physiological and psychological demands of the job on the worker.
Overall, industrial hygienists point out that the benefits of a well-designed, ergonomic work environment can
include increased efficiency, fewer accidents, lower operating costs. and more effective use of personnel.
In sum, industrial hygiene encompasses a broad spectrum of the working environment. Early in its history OSHA
recognized industrial hygiene as an integral part of a healthful work setting. OSHA places a high priority on using
industrial hygiene concepts in its health standards and as a tool for effective enforcement of job safety and health
regulations. By recognizing and applying the principles of industrial hygiene to the work environment, America's
workplaces will become more healthful and safer.
What Help Can OSHA Provide?
Safety and Health Program Management Guidelines
Effective management of worker safety and health protection is a decisive factor in reducing the extent and
severity of work-related injuries and illnesses and their related costs. To assist employers and employees in
developing effective safety and health programs, OSHA published recommended Safety and Health Program Management
Guidelines (Federal Register 54(18):3908-3916, January 26, 1989). These voluntary guidelines apply to all places
of employment covered by OSHA. The guidelines identify four general elements that are critical to the development of
a successful safety and health management program:
- management commitment and employee involvement,
- worksite analysis,
- hazard prevention and control, and
- safety and health training.
The guidelines recommend specific actions under each of these general elements to achieve an effective safety
and health program. A single free copy of the guidelines can be obtained from the U.S. Department of Labor OSHA/OICA
Publications. P.O. Box 37535, Washington, DC 20013-7535, by sending a self-addressed mailing label with your
request.
State Programs
The Occupational Safety and Health Act of 1970 encourages states to develop and operate their own job safety
and health plans. States administering occupational safety and health programs through plans approved under section
18(b) of the Act, must adopt standards and enforce requirements that are "at least as effective" as federal
requirements. There are currently 25 state plan states: 23 cover the private and public sectors (state and local
governments) and 2 cover the public sector only. For more information on State Plan states, see the list of states
with approved plans at the end of this publication.
Free Onsite Consultation
Consultation assistance is available on request to employers who want help in establishing and maintaining a
safe and healthful workplace. Largely funded by OSHA, the service is provided at no cost to the employer. Primarily
developed for smaller employers with more hazardous operations, the consultation service is delivered by state
government agencies or universities employing professional safety consultants and health consultants. Comprehensive
assistance includes an appraisal of all work practices and environmental hazards of the workplace and all aspects of
the employer's present job safety and health program.
The program is separate from OSHA'S inspection efforts. No penalties are proposed or citations issued for any
safety or health problems identified by the consultant. The service is confidential.
For more information concerning consultation assistance, see the list of consultation projects at the end of
this publication.
Voluntary Protection Program (VPPs)
Voluntary Protection Programs (VPPs) and onsite consultation services, when coupled with an effective
enforcement program, expand worker protection to help meet the goals of the Act. The three VPPs--Star, Merit, and
Demonstration--are designed to recognize outstanding achievement by companies that have successfully incorporated
comprehensive safety and health programs into their total management system. They motivate others to achieve
excellent safety and health results in the same outstanding way as they establish a cooperative relationship among
employers, employees, and OSHA.
For additional information on VPPs and how to apply, contact the OSHA area or regional offices listed at the
end of this publication.
Training and Education
OSHA area offices offer a variety of information services, such as publications, audiovisual aids, technical
advice, and speakers for special engagements. The OSHA Training Institute in Des Plaines, IL, provides basic and
advanced courses in safety and health for federal and state compliance officers, state consultants, federal agency
personnel, and private sector employers, employees, and their representatives.
OSHA also provides funds to nonprofit organizations, through grants to conduct workplace training and
education in subjects where OSHA believes there is a lack of workplace training. Grants are awarded annually and
grant recipients are expected to contribute 20 percent of the total grant cost. For more information on grants,
training, and education, contact the OSHA Training Institute, Office of Training and Education, 1555 Times Drive,
Des Plaines, IL 60018; telephone (847) 297-4810.
