Slide Show Notes
Industrial hygiene, or IH as we’ll call it for the rest of the session, is nothing new to the workplace. People have been aware of industrial hygiene for centuries.
In the early 20th century in the United States, Dr. Alice Hamilton led efforts to improve industrial hygiene. She observed industrial conditions firsthand and startled mine owners, factory managers, and state officials with evidence that there was a correlation between worker illness and their exposure and the risks posed by their work environment. 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 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 In most states, there is some compensation coverage for workers contracting industrial illnesses. 6

7. What Is the Connection Between IH & OSHA?
“We rely on industrial hygienists to evaluate jobs for potential health hazards.”
—OSHA
Slide Show Notes
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 Occupational Safety and Health Act and its regulations.
Under the law, OSHA develops and sets mandatory occupational safety and health requirements applicable to the more than 6 million workplaces in the United States. OSHA relies on, among many others, industrial hygienists to evaluate jobs for potential health hazards.
Developing and setting mandatory occupational safety and health standards involve determining the extent of employee risk and exposure to hazards and deciding what is needed to control these hazards, thereby protecting the workers. Industrial hygienists are trained to anticipate, recognize, evaluate, and recommend controls for environmental and physical hazards and risks that can affect the health and well-being of workers.

Industrial hygienists are involved in:
Compliance
Standards
Technical assistance
Enforcement
Hazard ID & elimination
Slide Show Notes
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 materials, 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.
In addition, industrial hygienists analyze, identify, and measure workplace risks, 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. 8

9. How Does IH Help Protect You on the Job?

Let’s continue to the next slide now and talk about how industrial hygiene helps identify workplace hazards. 12

13. How Are Workplace Hazards Identified?
Worksite analysis
Slide Show Notes
A worksite analysis is an essential first step that helps an industrial hygienist determine what jobs and workstations are the sources of potential problems.
During a 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 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.

14. How Does IH Control Workplace Hazards?
WORK PRACTICE
ENGINEERING
Slide Show Notes
Industrial hygienists recognize three controls that are the primary means of reducing employee exposure to occupational hazards. They are:
Engineering
Work practice, and
Administrative controls
ADMINISTRATIVE

15. Engineering Controls Slide Show Notes
Engineering controls minimize employee exposure or risk by either controlling, reducing, or removing the hazard at the source or isolating the worker from the hazard.
Engineering controls include eliminating toxic or hazardous materials and replacing with less hazardous ones, enclosing work processes or confining work operations, and installing general and local ventilation systems.
Think about the engineering controls used in your work area to protect you from health hazards.
Discuss engineering controls used in the workplace and how they help protect workers from health hazards. 15

16. Work Practice Controls
Slide Show Notes
Work practice controls alter the manner in which a task is performed. Some fundamental and easily implemented work practice controls include:
Following proper procedures that minimize exposures while operating production and control equipment;
Inspecting and maintaining process and control equipment on a regular basis;
Implementing good housekeeping procedures;
Providing appropriate supervision; and
Mandating that eating, drinking, smoking, chewing tobacco or gum, and applying cosmetics in regulated areas be prohibited.
Think about the safe work practices you are required to follow and how they help protect you from health hazards on the job.
Discuss work practice controls trainees are required to follow, and explain how these work practices help protect workers from hazards. 16

17. Administrative Controls
Slide Show Notes
Administrative controls include controlling employee 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, personal protective equipment is required. PPE such as gloves, safety goggles, respirators, hard hats, safety shoes, and protective clothing may be required.
To be effective, PPE must be individually selected, properly fitted and periodically refitted, conscientiously and properly worn, regularly maintained, and replaced as necessary.
Think about any administrative controls that apply to your job and how these controls help protect you. Also think about the PPE you are required to wear and how it helps protect you from health hazards.
Discuss administrative controls established to protect workers and how these controls help prevent injuries and illness. Also talk about PPE trainees are required to use and how this equipment protects them from health hazards. 17

18. Examples of Job Hazards
Air contaminants
Chemical hazards
Biological hazards
Physical hazards
Ergonomic hazards
Air contaminants
Chemical hazards
Biological hazards
Physical hazards
Ergonomic hazards
Slide Show Notes
To be effective in recognizing and evaluating on-the-job hazards and recommending controls, industrial hygienists must be familiar with the hazards’ characteristics. Potential hazards can include:
Air contaminants,
Chemical hazards,
Biological hazards,
Physical hazards, and
Ergonomic hazards.
Let’s take a look at each one of these. 18

19. Air Contaminants Dusts Fumes Mist Vapors Fibers Gases Slide Show Notes
Air contaminants can exist as solids, liquids, or gases. The most common are:
Dusts—solid particles generated by handling, crushing, grinding, colliding, exploding, and heating materials like rock, metal, wood, and grain. Dusts can be seen by the naked eyes, and they can be filtered out by the lungs.
Fumes—formed when material from a solid condenses in cool air. Fumes may not be seen by the unaided eye and can get deep into the lungs.
Mist—a liquid suspended in the atmosphere. Mists can be seen and can be caught by the lungs or can be absorbed into the skin.
Vapors—created by evaporation. They cannot be seen and can easily be absorbed into the body.
Fibers—solid particles which are generally long and thin. Fibers can get deep into the lungs and can cling and irritate.
Gases—formless fluids that expand to occupy the space they are in. Gases can be absorbed into the body.

20. Hazards Due to Chemical Properties
The degree of risk depends on:
Nature and potency of material
Magnitude and duration of exposure
Route of entry
The degree of risk depends on:
Nature and potency of material
Magnitude and duration of exposure
Route of entry
Slide Show Notes
Workers can be exposed to many types of risks due to chemical properties of a material through breathing, direct contact with the skin, or by ingesting. Some of these materials can be simply irritating, or some can be toxic. The degree of risk to the worker depends on several factors:
The nature and potency of the material,
The magnitude and duration of exposure, and
The route of entry.
Information about the risk to workers can be found on the material safety data sheet, which is supplied by the manufacturer. 20

21. Biological Hazards Bacteria Viruses Fungi Slide Show Notes
Biological hazards include:
Bacteria,
Viruses,
Fungi, and other living organisms that can cause infections, allergic reactions, and illnesses by contact with, or entering the body.
Occupations that deal with plants, animals, food, or food processing may expose workers to biological hazards, as well as the medical field. Using proper PPE, as well as handwashing are good practices to curb the risk of exposure.

22. Physical Hazards Electromagnetic radiation Noise Vibration
Illumination
Temperature
Slide Show Notes
Physical hazards include levels of:
Ionizing and nonionizing radiation,
Noise,
Vibration,
Illumination, and
Temperature.
Limiting the exposure time and distance to these hazards is one way to reduce risk. Also, using engineering controls, such as quieting walls and equipment, and shields can help. 22

23. Ergonomic Hazards Eye strain Repetitive motion injuries
Lifting injuries
Slide Show Notes
Ergonomic hazards include:
Eye strain,
Repetitive motion injuries, and
Lifting injuries.
These hazards can be avoided by using better-designed tools and equipment that meet workers’ needs. Beginning with a worksite analysis, employers can set up procedures that include redesigning workspaces, teaching about good work practices like proper lifting, using administrative work controls such as rest breaks and, if necessary, providing PPE to help control these hazards. 23

24. How Can You Promote a Safe & Healthy Workplace?
Report
Cooperate
Use engineering controls
Wear assigned PPE
Follow safe work practices
Slide Show Notes
You can help promote a safe and healthy workplace by taking five simple steps:
One, report risks and hazards right away;
Two, cooperate in investigations and inspections, and with monitoring, testing, and medical evaluation programs;
Three, use engineering controls when necessary to control workplace hazards;
Four, wear and properly maintain assigned PPE; and
Five, always follow safe work practices.
