Class Vocabulary

Vocabulary TermDefinition
accumulation The concentration or build-up of a substance or effect.
acute exposure Exposure that occurs suddenly or over a short period of time.
AIDS Acquired immune deficiency syndrome. AIDS is a hazardous bloodborne illness.
asbestos A naturally occurring fibrous mineral. Inhaled asbestos becomes stuck in the lungs and can cause a potentially fatal lung disease called asbestosis.
biological hazard A naturally occurring substance that can be harmful to employees.
bloodborne pathogen A hazard that is carried by the blood. An employee may be exposed to a bloodborne pathogen when another employee receives a cut or injury that results in bleeding.
Centers for Disease Control and Prevention A branch of the Department of Health and Human Services that works to prevent and control infectious and chronic diseases, injuries, workplace hazards, disabilities, and environmental health threats.
chemical hazard An element or mixture of elements or synthetic substances that are considered harmful to employees.
chronic exposure Exposure that occurs over a long period of time.
dosage A measurable amount of a substance or a hazard such as a chemical or noise.
duration The length of time an individual is exposed to a hazard, such as a chemical gas, a loud noise, or an uncomfortable position.
dust A small particle of a solid substance. Dust is usually powdery.
electromagnetic Magnetism that is created using electrical waves.
environment The factors that make up the surroundings in a given place. The workplace environment consists of various environmental components, including noise and air quality.
environmental component One of the factors that makes up an environment. In the workplace, these include noise, air quality, machine vibration, workstation height, and any materials contacting the employee.
environmental hazard A component in the workplace environment that can cause injury, illness, or death.
Environmental Protection Agency The governmental agency responsible for administrating laws to control and reduce pollution of air, water, and land systems (EPA).
ergonomic hazard A physical factor within the environment that harms the musculoskeletal system. Ergonomic hazards include uncomfortable workstation height and poor body positioning.
exposure limit The maximum amount or concentration of a hazard that can be present or that a worker may experience without causing a health hazard.
eye contact Physically touching the eyes. Liquid and gaseous forms of chemicals can enter the body when they are absorbed through the eyes.
fiber A small piece or thread of a solid substance that is longer than it is wide. Wood, fabric, and some naturally occurring elements consist of fibers.
fume A dispersion of solid particles in a gas. Fumes are often produced from high heat, such as during welding.
fungi Plant-like organisms such as mold or mushrooms that absorb their food from other living or dead organisms.
gases A basic flowing and expanding form of a substance, such as oxygen. A gas is a flowing state of matter that expands to fill whatever container it occupies.
general duty clause A statement contained within OSHA's standards that requires employers to furnish employment and places of employment which are free from recognized hazards to the health and safety of their employees. The clause covers situations for which there is no specific standard.
hazard communication The means through which employers inform their employees about hazards in the workplace, including training and MSDS.
illness Sickness or impairment that often affects a whole body or whole system, such as the lungs. Illnesses have many causes, including chemical exposure.
ingestion Eating or swallowing a substance.
inhalation Breathing in an airborne substance.
injury Damage or harm that is often localized. Injuries can be caused by events, such as accidents, or physical trauma from something like repetitive motion.
interaction The combination of two or more substances that produce a new substance. Interactions between chemicals or medicines may be potentially hazardous.
latency The time that elapses between the first exposure to the hazard and the moment when the injury or illness appears.
liquid A basic wet or flowing form of a substance, such as water. Many solids turn to the liquid state at elevated temperatures, such as molten metal or wax.
material safety data sheet Mandatory information that must accompany almost every chemical in the workplace except for items like cleaning supplies. An MSDS includes details such as the risks, precautions, and first aid procedures associated with the chemical.
mist A suspension of microscopic liquid particles of various sizes in the air. The spray of metal cutting fluids often produces mist.
musculoskeletal system Muscles, joints, bones, and related structures.
National Institute for Occupational Safety and Health A branch of the Centers for Disease Control and Prevention that performs research and issues guidelines on worker safety issues.
natural element A pure substance, such as gold, oxygen, or mercury, that cannot be further broken down.
Occupational Safety and Health Administration A government agency under the U.S. Dept. of Labor that helps employers reduce injuries, illnesses, and deaths in the workplace (OSHA).
personal protective equipment Any example of various safety equipment that workers wear or use to prevent injury in the workplace. Safety glasses are common personal protective equipment (PPE).
physical hazard A factor within the environment that can harm the body without necessarily touching it. Vibration and noise are examples of physical hazards.
poor positioning Awkward location of the body or body parts that leads to injury.
radiation Energy transmitted through space as waves, such as radio waves or light waves.
rate of exposure The combination of dosage and duration.
reaction The result of two or more substances coming together. Reactions include a gas created by mixing two liquid chemicals or a breathing problem caused by inhaled fibers that become trapped in the lungs.
repetitive motion Persistent and continual movement that can cause localized musculoskeletal injury or illness. Assembly line workers often perform tasks that require repetitive motion.
respirator A breathing device worn to prevent inhalation of hazardous substances.
sensitive A greater susceptibility to a hazard because of an underlying condition, such as a skin or lung condition.
skin contact Physically touching the skin. Chemicals that make skin contact can be absorbed through the pores or can harm the skin's surface.
solid A basic non-flowing form of a substance. A solid is the room temperature form of some substances, such as aluminum, or the frozen form of others, such as water.
spore The reproductive cells of molds and fungi. Spores can cause skin reactions or illnesses when they are touched, inhaled, or ingested.
systemic Affecting the whole body. Systemic illnesses may cause symptoms in one or two areas, such as the lungs and stomach, but the whole body is affected.
toxic Poisonous or harmful. Many substances are harmless with small amounts of exposure and toxic with large amounts of exposure.
vapor The gaseous form of a substance that is a liquid or solid at normal temperatures. Water vaporizes into steam when heated.
vibration Rapid and repetitive back and forth movement.
wave An undulation or vibration of a form of energy. Waves include microwaves and radio waves.
