Class Vocabulary
Term
Definition
air-purifying respirator
A form of PPE that consists of a face mask containing filters that remove contaminants from the atmosphere and make the air breathable.
air-supplying respirator
A form of PPE that consists of a face mask that is attached by a line to a wearable or external tank of air.
asphyxiating hazard
A type of atmospheric hazard that interferes with the ability to breathe. Gases and dusts may cause asphyxiation if inhaled.
atmospheric hazard
A confined space hazard that is present in the environment. Atmospheric hazards are categorized as flammable, toxic, irritant, and asphyxiating.
atmospheric testing
Measurement of the content of the environment using electronic equipment.
authorized attendant
Someone trained in permit-required confined space entry and surface rescue who remains outside of the confined space and monitors the safety of the authorized entrant.
authorized entrant
A person who has been trained to enter and perform work within a confined space.
blanking
A method of blocking feed lines to prevent the flow of materials or substances.
bleeding
A method of draining feed lines to prevent the flow of materials or substances.
carbon dioxide
A colorless, odorless gas that is produced by burning or decaying materials and by respiration.
cardiopulmonary resuscitation
A technique, commonly known as CPR, designed to temporarily circulate oxygenated blood through the body of a person whose heart has stopped.
caustic chemical
A substance that can burn or destroy living tissue.
certify
To offer proof of accomplishment. Employees are given a certificate or other proof when they have completed confined space training.
combustible dust
A type of atmospheric hazard that consists of fine grains of material that are capable of exploding or catching fire.
communication hazard
A type of general confined space hazard that exists when persons inside the space are unable to speak to or signal those on the outside and vice versa.
confined space
An area with limited means of entry or exit that is large enough for an employee to enter and perform work.
decomposition
The breakdown or decay of organic materials, such as plants or animals.
decontaminating
Using various cleaning methods, including rinsing or steaming the interior of a confined space, to remove hazardous substances.
engulf
To be submerged by a substance such as water, grain, or earth, as it completely flows over and covers a person.
entry and exit hazard
A type of general confined space hazard that exists when insufficient preparations have been made to assure that employees can exit a space quickly.
entry supervisor
The person most responsible for verifying that the confined space is as safe as possible to enter. The role of the entry supervisor is usually filled by the employer, foreman, or crew chief.
environment
The factors that make up the surroundings in a given place. A confined-space environment includes air content and quality.
fermenting
The interaction of yeast and sugar that produces alcohol and carbon dioxide. The process of winemaking involves fermentation.
flammable hazard
A type of atmospheric hazard that occurs when substances that are likely to catch fire are present. Both oxygen and dust are flammable hazards.
frostbite
Damage to human tissue caused by exposure to extreme cold.
general hazard
One of three types of confined space hazards. General hazards may be mechanical, communication, or entry and exit hazards.
ground fault interrupter
An electrical safety device that disconnects power by breaking a circuit when surges of electricity are detected. GFI circuits are usually used around sources of water.
harness
A form of PPE that consists of a series of straps connected around the legs, waist, and shoulders that is attached to a hoist and used to pull entrants out of confined spaces.
heat exhaustion
An illness brought on by exposure to high temperatures that is characterized by faintness, dizziness, and heavy sweating.
heat stroke
A life-threatening illness brought on by exposure to high temperatures. Heat stroke occurs when the body is unable to cool itself down.
hoist
A device attached by a line to a harness used to pull entrants out of confined spaces.
hot work
Tasks such as welding, brazing, or cutting that produce heat.
hypothermia
A rapid physical and mental collapse that occurs when the body is exposed to cold temperatures and is unable to warm itself.
irritant hazard
A type of atmospheric hazard that causes inflammation or irritation to the eyes, skin, or respiratory system. Chemical gases are a type of irritant.
isolated
A machine component or feed line that has been physically or manually blocked or disconnected so that it cannot accidentally start up or allow the flow of substances.
isolating
Physically or manually blocking or disconnecting a machine component or feed line so that it cannot accidentally start up or allow the flow of substances.
limited-access confined space
A confined space that has a very small opening for entry and exit. Sewers and silos are examples of limited-access confined spaces.
lockout
A method of protecting employees from accidental machine startup through proper locking or blocking of machines that are undergoing maintenance.
mechanical hazard
A type of general confined space hazard that exists when electrical or mechanical equipment may be accidentally activated.
noise
Any unwanted sound. Noise is a hearing hazard.
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.
open-top confined space
A confined space, with or without a cover, that is open at the top. Open-top confined spaces usually have a depth that restricts the normal movement of air.
permit-required confined space
A confined space that contains at least one additional hazard, such as a hazardous atmosphere, that requires supervisor permission for entry. Permit spaces may be entered only by certified employees.
permit-required confined space program
A written set of policies and procedures for entering permit-required spaces. OSHA requires every employer whose employees enter permit-required spaces to develop a written plan.
personal protective equipment
Any example of various safety equipment that workers wear or use to prevent injury in the workplace. Safety glasses are common PPE.
physical hazard
A type of non-chemical confined space hazard that affects the body. The three types of physical hazards are temperature, noise, and vibration.
primary irritant
A type of atmospheric hazard that harms only the parts of the body that it touches and does not cause further injury or disease.
prohibited condition
Any existing hazardous condition within a permit-required confined space. The prohibited condition may not have been listed on the entry permit, may be listed on the entry permit as having been removed, or may have been unknown at the time of entry.
purging
The process of clearing the environment within a confined space. Purging may be accomplished by forcing air, water, or another substance into the space to push the hazardous substance out.
record keeping
Recording the details of the planned permit-entry process, as well as the results of entries and acquisition of necessary paperwork.
rescue team
Individuals trained in permit-required confined space entry and rescue.
secondary irritant
A type of atmospheric hazard that harms the parts of the body that it touches and also causes further injury or disease.
sewer
A pipe that carries waste water, such as sewage or runoff from rain.
silo
A tall, cylindrical structure often used for storing grain.
storage tank
A large container made of plastic or metal used to hold liquid or powdered substances.
systemic effect
A hazard that affects the whole body. Systemic hazards may cause symptoms in one or two areas, such as the skin or lungs, but the whole body is affected.

A method of protecting employees from accidental machine startup through labeling. Warning tags are placed on the switches or sources of power of machines that are undergoing maintenance
toxic hazard
A type of atmospheric hazard that can be poisonous or harmful. Gases and dusts may be toxic if inhaled.
ventilation
To allow or cause the movement of fresh air into a confined space.
vibration
The fast, back-and-forth movement of an object. Vibration is a physical hazard.
voltage
A measure of electrical pressure. Human contact with high-voltage electricity is usually fatal.
