Class Vocabulary

Term	Definition
base plate	The bottom of a tool such as a circular saw that must be guarded except for when the tool is in use.
chisel	A sharp metal tool that is used to cut or chip workpiece materials. Chisels must remain clean and sharp.
conductor	A material that is very effective at conducting electricity. When using electric tools, do not wear or stand on objects that are conductors.
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.
earplugs	Ear wear that protects hearing. Earplugs are inserted inside the ear to muffle outside noises.
electric shock	The flow of electricity through the body. Severe electric shock can be fatal.
electric tool	A power tool that is powered by electricity. Electric tools require observing electric safety guidelines.
ergonomics	The study of designing devices to decrease operator discomfort or fatigue and increase productivity.
eye wash station	A designated station in an easily accessible area in which employees may flush their faces with water in the event of an emergency.
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.
fire extinguisher	A portable device that uses a rapid spray of chemicals to put out small fires.
fire shield	A flame-resistant, tarp-like device that is used to isolate a work area and protect bystanders and nearby equipment from applications that throw sparks.
flammable	An object that can quickly catch fire if it comes in contact with sparks or fire.
flange	A flat or raised metal disk that helps deflect mounting stresses from the hole in a grinding wheel.
fuel-powered tool	A tool that is powered by fuel, usually gasoline. Fuel-powered tools require proper ventilation.
fume	A cloud of particles suspended in a gas. Applications that emit fumes require proper ventilation.
GFCI	Portable ground fault circuit interrupters. A type of switch that is disabled if the electricity should come into contact with water. GFCIs should be used whenever there is a chance for electricity to come into contact with water.
grounded	Safely connected to a neutral body, like the earth, which can absorb a stray electrical charge. Electric tools must be grounded to help prevent electric shock.
hand tool	A tool that is "powered" by an operator, such as a hammer or screwdriver. Hand tools must be kept clean and sharp in order to avoid injury.
hand wash station	A designated station in an easily accessible area in which employees may wash their hands.
hard hat	A lightweight, protective head covering, usually made of plastic, used to protect the head from impacts, bumps, and electrical shock.
hydraulic tool	A tool that is powered by a liquid. Hydraulic tools must be used within their proper specifications.
jackhammer	A powerful pneumatic tool that is used to chisel or hammer away at surfaces. Because of their vibrating motion, jackhammers require special safety considerations.
lockout	A safety procedure required by OSHA that takes steps to dissipate all stored energy during maintenance work. Never try to operate a machine that is under lockout.
mounting	The device on which an abrasive wheel rests. The abrasive wheel must be able to move freely without obstruction on the mounting.
mushroomed head	A condition that occurs commonly to chipping tools where the head of the tool is flared out due to excessive use. Using tools with mushroomed heads is dangerous because pieces can fly off and hit the employee or other bystanders.
muzzle	A safety guard that protects employees from coming into contact with dangerous parts of the tool. For example, a muzzle covers a nailgun until it is pressed against a workpiece.
nut	A component, usually made of metal, with a threaded hole that mates with a bolt. Using the proper tool for tightening nuts is an important safety precaution.
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.
pinch point	Any place where two components meet that can cause an injury if you come into contact with the area.
pneumatic tool	A tool that is powered by compressed air.
point of operation	The area where the tool comes into contact with the workpiece. Employees must never place anything in the path of the point of operation.
posture	Sitting or standing in a proper upright position. Many ergonomic injuries are avoided by assuming proper posture.
powder tool	A tool that is powered by gunpowder. Because they require special safety considerations, only approved personnel may use powder tools.
power tool	A tool that is powered by an external source, such as electricity or compressed air. Power tools must receive regular maintenance and be properly handled to avoid injury.
respirator	A breathing device worn to prevent inhalation of hazardous substances.
ricochet	To rebound from a surface. Employees must make provisions to ensure that fasteners can not ricochet off a surface.
ring-tested	Another term used to describe a sound test for grinding wheels.
safety screen	A protective screen that isolates a work area to protect bystanders and nearby equipment. Safety screens are similar to fire shields.
scaffolding	A raised platform on which employees can work at elevated heights.
screwdriver	A type of hand tool that tightens and loosens screws. Screwdrivers contain a grip on one end and a blade on the other end that corresponds to the head on the screw.
sensor switch	A safety device used on power tools. Sensor switches can have different designs, but the most common type allows the tool to operate while pressure is applied and does not allow the tool to operate when pressure is released.
shoe	Another term used to describe the base plate of a tool.
sound-tested	A test performed on an abrasive wheel to ensure that it is not cracked. If the wheel "rings" when a non-metallic object is lightly tapped on it, then it is not cracked.
spindle	The component of a tool that spins. For safety, spindles must be properly tightened and able to move freely without obstruction.
tagout	The visible labeling of a machine or equipment indicating that it is locked out and should not be used by unauthorized workers.
tool crib	A designated area where extra tools and accessories are kept. The tool crib is also typically where tools can be serviced or repaired.
tool retainer	A safety device that grips a tool to ensure that it is properly attached to its power source.
tool room	Another term for the tool crib.
ventilation	A means of providing fresh air.
vise	A workholding device with two jaws that grip and hold a workpiece in place.
wrench	A type of hand tool that tightens and turns bolts and nuts. Wrenches contain fixed or moving jaws or a round attachment that grips the nuts or bolts.
