Class Vocabulary

Term	Definition
absorption	A material's ability to soak up or become saturated with a liquid.
American National Standards Institute	A private, non-profit organization that administers the U.S. voluntary standards and conformity assessment system. ANSI provides a process for industry groups to create and publish the specifications for some PPE.
arm coverings	Fabric or leather sleeves that fit over the arms to protect from various hazards.
bump hat	A protective head covering used in areas of low clearance that offers minimal protection from minor impacts and abrasions.
butyl	A non-porous synthetic rubber that offers better protection from certain chemicals, such as some ketones, than other rubber or rubber-like materials.
class A hard hat	A protective head covering that provides impact and penetration resistance and limited voltage protection, up to 2,200 volts.
class B hard hat	A protective head covering that provides impact and penetration resistance and offers the highest level of protection against voltage and burns, up to 20,000 volts.
class C hard hat	A protective head covering that provides lightweight comfort and impact protection but offers no protection from electrical hazards.
combination foot and shin guards	A device that fits over the shins and most of the foot to protect from multiple hazards, including impacts.
compliance officer	The OSHA representative who enforces OSHA standards through inspection and investigation.
decibel	The unit by which the intensity of sound is measured.
duck	Closely-woven cotton fabric that resists penetration.
earmuffs	Full-ear coverings connected by a headband that require a perfect seal around the ear. Hair, facial hair, or facial movements may disrupt this seal.
electrical hazard safety-toe shoes	Non-conductive safety shoes made to prevent the wearer from completing an electrical circuit with the ground. These shoes can protect against circuits of up to 600 volts in dry conditions
electrically conductive shoes	Safety shoes that prevent explosions due to buildup of static electricity in certain environments, such as agricultural grain elevators.
face shield	A rigid, transparent plastic sheet that covers the worker's entire face to protect against dust or splashes. Because face shields do not protect against impacts, they are often worn with goggles.
finger guards	Devices used to protect one, two, or three fingers that may be exposed to a hazard, such as when the index finger, middle finger, and thumb of one hand are used to hold a fastener during assembly.
foundry shoes	Safety shoes with built-in safety toes that are constructed to insulate the wearer's feet from heat and molten metal. Foundry shoes are designed to keep hot metal from lodging in eyelets, tongues, laces, or other shoe crevices.
goggles	Tight-fitting eye protection that completely cover the eyes, the sockets, and the surrounding facial area. Goggles offer protection from impact, dust, chips, and splashes.
hard hat	A lightweight, protective head covering, usually made of plastic, used to protect the head from impacts, bumps, and electrical shock.
hazard	A source of danger or possible injury. Hazards can be physical hazards like falling objects or health hazards like chemical exposures.
hazard assessment	A written, formal appraisal of the safety risks that exist within a workplace. A hazard assessment is often performed by the safety team during a walk-through.
health hazard	A condition or situation that may result in an illness. Airborne particles, repetitive motions, and some chemicals can be health hazards.
hearing conservation program	An OSHA program designed to protect workers' hearing from noise exposure by requiring employees to monitor noise levels, test affected employees' hearing, and provide hearing protection.
laser goggles	Goggles that protect against the intense light produced by lasers. Laser goggles are chosen based on the equipment and operating conditions in the workplace.
latex	A milky substance found in rubber trees used to make a variety of products.
leather	Fabric made from cow hide that offers resistance to heat and other hazards.
leggings	Easily removable lower leg coverings made of leather or fabric that protect the legs from sparks and spatter.
lockout/tagout	A specific work safety procedure or practice that safeguards employees from the unexpected powering or startup of machinery and equipment, or the release of hazardous energy during service or maintenance activities.
metatarsal guard	A device that straps onto the shoe to protect the instep from impacts and crushing. Metatarsal guards may be made from aluminum, steel, plastic, or fiber.
neoprene	A synthetic rubber product that offers better protection from certain chemicals, such as dioxane, than other rubber or rubber-like materails.
nitrile	A rubber-like material that resists petroleum or oil compounds.
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.
paper-like fiber	A disposable material that has the properties of paper but behaves like fabric.
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 condition or situation that may result in an injury. Slippery surfaces, broken or missing walkway railings, and flying debris are physical hazards.
pre-formed earplugs	Professionally fitted ear protection made of silicone or rubber.
protective gloves	Gloves made from a variety of materials to protect the hands from hazards such as chemicals, heat, or abrasion.
requirement	A specific mandate that is contained in a standard. Training is a requirement of OSHA safety standards.
rubber	An elastic material made from the latex sap of the rubber tree.
rubberized fabric	Material that has been coated with rubber to change its behavior, such as to make it resistant to liquids.
safety shoes	The most common type of foot PPE that provides many different ways of protecting workers' feet, such as from heat, impact, or electrical shock.
safety spectacles	Protective eyeglasses with metal or plastic frames and impact-resistant lenses that may or may not offer vision correction. Many safety spectacles also have protective side shields.
silicone rubber	A pliable, formable polymer material.
single-use earplugs	Single-use, disposable, self-forming plugs made of waxed cotton, foam, or silicone rubber.
spatter	Molten metal spray produced during welding operations.
standard	An established policy on a particular practice or method. OSHA standards have the same power as law, and non-compliance can result in fines and other penalties.
static electricity	An electrical charge that builds up due to friction between two dissimilar materials.
toe guard	A device that fits over the toes of regular shoes to protect toes from being crushed. Toe guards may be made from aluminum, steel, or plastic.
toxicity	The degree to which something is poisonous.
treated cotton	Fabric made from cotton plants that has chemical additives that change its behavior, such as making it more fire-retardant or less slippery.
treated wool	Fabric made from sheep fur that has chemical additives that change its behavior, such as making it more fire-retardant or less slippery.
voltage	A unit of measurement of electrical force.
welding shield	A heat-resistant face covering that protects from spatter and sparks and contains a darkened lens to protect the eyes from the intense light produced during welding.
