Class Vocabulary

Vocabulary TermDefinition
caustic Capable of destroying something by chemical action. Certain safety gloves offer protection from caustic substances.
chemical Any element, compound, or mixture of elements and/or compounds.
dolly A platform on wheels used for moving heavy or awkward objects.
downtime The period of time when a machine or a factory is not operating and is not producing.
earmuffs A type of personal protective equipment that covers the entire outer ear. Earmuffs consist of two ear coverings connected by a band.
earplugs Ear wear that is inserted into the ears to protect hearing.
gear A wheel-shaped device with teeth around the perimeter that is used to transfer force and motion to another device. Multiple gears often mesh with one another to transfer motion.
glove A type of PPE worn on the hands and/or arms to reduce the risk of injury. Gloves should always be worn when handling chemicals or sharp objects.
hand truck A cart on wheels used for moving heavy objects. A hand truck can be pushed or pulled and is often equipped with a brake.
lockout device A device such as a lock and key or combination lock used to prevent equipment or machinery from being energized.
lockout/tagout A method of protecting employees from accidental machine startup through proper locking and labeling of machines that are undergoing maintenance.
lubricant A substance used to reduce friction between two surfaces in relative motion. Maintenance workers are often responsible for lubricating machines.
machine guard A shield or cover over hazardous areas on a machine to prevent accidental contact with body parts or to prevent debris, such as chips, from exiting the machine.
maintenance The necessary and basic support and repair of machines. Maintenance includes tasks such as lubricating, adjusting, and replacing parts.
non-slip base A safety device used to prevent a ladder from skidding or sliding. Rubber safety feet are an example of a non-slip base.
OSHA The 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.
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).
routine maintenance The process of performing regular maintenance tasks, such as lubrication. Routine maintenance can often be performed without locking out a machine.
safety block A device used during maintenance to prevent injury by blocking the movement of components or locking components in place. The safety block is placed in a machine to prevent accidental movement.
safety glasses Protective eyewear, usually made of thick plastic, that shields the eyes from flying debris. Safety glasses with side shields or safety goggles must be worn in any work area.
scaffold A raised platform on which employees can work at elevated heights.
shop debris Pieces of dust, dirt, or other waste material in the manufacturing shop, often generated by machinery. Metal chips are an example of shop debris.
steel-toed boots Protective footwear made with reinforced steel in the toe area, designed to prevent foot injury from falling objects.
tagout device A prominent warning device, such as a tag, that can be securely attached to a machine or power source to alert employees that equipment is not to be operated until the tag is removed.
