Industrial Hygiene Flashcards
It is the science of anticipating, recognizing, evaluating, and controlling workplace conditions that may cause workers’ injury or illness.
Industrial hygiene
They 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.
Industrial hygienists
He is known as the “father of industrial medicine”
Bernardo Ramazzini
First comprehensive book on industrial medicine published in Italy
De Morbis Artificum Diatriba (The Diseases of Workmen)
Trained to anticipate, recognize, evaluate, and recommend controls for environmental and physical hazards that can affect the health and well-being of workers.
Industrial hygienists
It removes the hazard. This strategy totally eliminates the hazard from the workplace. This should be the top priority for all safety professionals including industrial hygienists. An example of this strategy includes replacing a
hazardous chemical with a totally non-toxic, safe, chemical.
Elimination
It reduces the hazard. This strategy should be used if it is not feasible to eliminate the hazard. The idea is to
replace the hazard with a less hazardous substitute.
Substitution
It remove/reduce the hazard through design. This strategy involves the design or redesign of tools, equipment, machinery and facilities so that hazardous chemicals are not needed or that exposure to those hazardous
chemicals are not possible.
Engineering controls
It promote employee awareness of hazards. It is merely visual, audible, and/or tactile indicators that warn people of potential danger.
Warnings
Eliminate/reduce exposure to
hazards. This strategy to helps to reduce exposure by developing and implementing effective training, policies, processes, procedures, practices and safety rules.
Administrative controls
Eliminates/reduces exposure through personal barriers. This strategy is generally used in conjunction with the other strategies to reduce exposure. When effective elimination, substitution and engineering controls are not feasible appropriate this may be required.
Personal Protective Equipment (PPE)
It is commonly classified as either particulate or gas and vapor contaminants.
Air contaminants
Formless fluids that expand to occupy the space or enclosure in which they are confined.
Gases
It is 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.
Fumes
It change into vapors and mix with the surrounding atmosphere through evaporation.
Liquids
It is finely divided liquid suspended in the atmosphere. They 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.
Mists
It is also a form of a mist characterized by highly respirable, minute liquid particles.
Aerosols
Solid particles whose length is several times greater than their diameter.
Fibers
Gaseous form of substances that
are normally in a solid or liquid state at room temperature and pressure. Formed by evaporation from a liquid or solid and can be found where a worker would clean and/or paint as well as where solvents are used.
Vapors
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.
Dusts
It refers to the presence or absence
of air pollutants in buildings.
Indoor air quality
It includes 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.
Biological hazards
They have the ability to adversely affect human health in a variety of ways, ranging from relatively mild, allergic reactions to serious
medical conditions, even death.
Biological agents
It is an acute infectious disease caused by a spore-forming bacterium called Bacillus anthracis.
