Class Vocabulary

Vocabulary TermDefinition
accumulator Hydraulic components used to store hydraulic fluid. Accumulators are designed to increase or relieve pressure in the system.
cage A protective structure that separates a working machine tool from the operator. Cage doors must be closed in order for the machine to operate.
check valve A hydraulic control valve that allows fluid to flow in one direction.
contaminant Any foreign substance that may cause a loss of efficiency or a breakdown in a fluid system.
Control of Hazardous Energy OSHA's proper title for the lockout/tagout safety standard. The standard protects employees by requiring practices and procedures that prevent accidental machine startup for machines that are undergoing maintenance.
cylinder A type of linear actuator that uses a piston to produce motion in a straight line. A cylinder is also known as a piston actuator.
earplug A protective device that blocks excessive noise from entering the ear. Earplugs vary in type and can be made from wax, cotton, foam, silicone, and rubber.
electrical energy The energy created by the movement of electrons. Electrical energy can be converted into light, heat, or motion.
emergency cut-off valve A safety device that halts all hydraulic action immediately. An emergency cut-off valve is located between the pump and the master valve in a hydraulic system.
first degree burn A mild burn that affects the first layer of skin.
force multiplication The exponential increase in available power usually associated with tools and power transmission systems.
four-hand control A control that requires two operators to start and stop the machine. Four-hand controls are used as a safety precaution and can be pilot valves or electric push buttons.
Frostbite Partial freezing of the body tissue. Frostbite is caused by exposure to extremely cold temperatures.
gloves Protective hand covers that reduce the risk of injury and exposure to high temperature fluids.
gown A protective body cover that reduces the risk of exposure to fluids and debris.
hand pump A manual device that actuates valves in hydraulic systems. A hand pump can be used instead of a hydraulic pump.
hydraulic safety valve A safety device that relieves excess pressure in a hydraulic system. Hydraulic safety valves are used used in conjunction with a rotating cylinder and a check valve.
hydraulic system A power transmission system that uses the force of flowing liquids to transmit power.
injection injury A puncture of the skin or body tissue caused by high-pressure fluid.
kinetic energy Energy of motion.
lockout device A device that uses positive means such as a lock and key or combination lock to hold an energy-isolating mechanism in a safe position and prevent equipment or machinery from being energized.
lockout/tagout The common term for OSHA's Control of Hazardous Energy Standard. Lockout/tagout practices protect employees by preventing accidental machine startup through proper locking and labeling of machines that are undergoing maintenance.
mask A protective cover that protects mucous membranes such as the nose and mouth from exposure to fluid, toxic fumes, dust, and debris.
master valve A directional control valve used in hydraulic and pneumatic systems. Master valves are typically three-way or four-way valves.
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 hazards, precautions, and first-aid procedures associated with the chemical.
National Institute for Occupational Safety and Health A division of the Centers for Disease Control that is responsible for conducting research for the prevention of work-related illnesses and injuries. The National Institute for Occupational Safety and Health is abbreviated as NIOSH.
Occupational Safety and Health Administration The United States government agency that regulates the conditions in working environments to ensure the health and safety of employees. The Occupational Safety & Health Administration is abbreviated as OSHA.
Pascal's Law A hydrostatic principle that states when pressure is applied to a contained fluid, the force is transmitted equally in all directions.
personal protective equipment Any example of various safety equipment that workers wear or use to prevent injury in the workplace. Safety glasses, gloves, masks, gowns, and earplugs are common personal protective equipment (PPE).
pilot valve A valve that actuates the master valve.
pinhole leak The loss of hydraulic or pneumatic fluid through a small hole, usually found on a fluid conductor. Pinhole leaks can reduce system efficiency and cause serious injection injuries.
pneumatic system A power transmission system that uses the force of flowing gases to transmit power.
potential energy Stored energy resulting from an object's position or from internal pressure.
preventive maintenance Maintenance performed while a machine is in working order to keep it from breaking down.
protective eyewear Eye covers that reduce the risk of injury and exposure to fluid, dust, and debris. Protective eyewear includes goggles and safety glasses.
psi Pounds per square inch. Pounds per square inch is a unit of measurement for pressure.
pump A mechanical device used to move liquids and gases.
safety clip A latch on a power tool that prevents the trigger from being depressed. Safety clips can also secure the tool to the fluid line.
second degree burn A more severe burn that affects the first and second layers of skin.
tagout device A prominent warning device, such as a tag, that can be securely attached to an energy-isolating mechanism to alert employees that equipment is not to be operated until the tag is removed.
thermal energy Energy resulting from the motion of particles. Thermal energy is a form of kinetic energy and is transferred as heat.
third degree burn The most severe type of burn that affects the first, second, and third layers of the skin.
two-hand control A control that requires both of an operator's hands to start and stop the machine. Two-hand controls are used as a safety precaution and can be pilot valves or electric push buttons.
