Buddy-Breathing Device. An accessory to self-contained
						  breathing apparatus which permits a second person to share the same air supply
						  as that of the wearer of the apparatus.
Enclosed Structure. A structure with a roof or ceiling
						  and at least two walls which may present fire hazards to employees; such as,
						  accumulations of smoke, toxic gases and heat, similar to those found in
						  buildings.
Fire Fighter. An employee who is assigned to fire
						  fighting activity, and is required to respond to alarms and perform emergency
						  action at the location of a fire or fire related danger. Included are the
						  employees of fire departments, fire protection districts, state fire agencies,
						  organized fire companies, and private fire brigades when engaged in fire
						  fighting activity.
Fire Fighting Activity. Physical action taken in the
						  direct act of fire suppression, and rescue or hazardous duties performed at the
						  location of a fire emergency.
Harmful Exposure. An exposure to dusts, fumes, mists,
						  vapors, or gases:
(a) In excess of any
						permissible limit prescribed by Section
						5155; or
(b) Of such a nature by inhalation as to
						result in, or have a probability to result in, injury, illness, disease,
						impairment, or loss of function.
Hazardous Environment. A place where a fire fighter is
						  likely to receive a harmful exposure to a hazardous substance, or be exposed to
						  physical or mechanical hazards which are likely to cause injury.
Hazardous Substance. One which by reason of being
						  explosive, flammable, poisonous, corrosive, oxidizing, irritant or otherwise
						  harmful, is likely to cause injury.
Long Duration Breathing Device. A self-contained
						  respiratory protective device designed to provide the user with a respirable
						  atmosphere for a minimum service time of one hour.
Overhaul. The final stages of fire extinguishment,
						  after the main body of a fire has been controlled, during which all traces of
						  fire are extinguished, where the potential for harmful exposure still
						  exists.
Primary Eye Protection. A protective device
						  specifically intended to shield the eyes from certain hazards while permitting
						  vision.
Private Fire Brigade. An organized group of private
						  industry fire personnel who may also be assigned to other functions, but who
						  have priority obligation to fire protection. Fire fighting responsibility may
						  be independent, under mutual-aid agreement, or supported by regular fire
						  service assistance.
Proximity Fire Fighting. Specialized fire fighting
						  operations that can include the activities of rescue, fire suppression, and
						  property conservation at incidents involving fire producing high levels of
						  radiant heat as well as conductive and convective heat.
Quick Disconnect Valve. A device which starts the flow
						  of air by inserting of the hose (which leads from the facepiece) into the
						  regulator of self-contained breathing apparatus, and stops the flow of air by
						  disconnection of the hose from the regulator.
Respiratory Protective Device (RPD). A breathing device
						  designed to protect the wearer from oxygen-deficient, or hazardous
						  atmosphere.
(A) Self-contained
						breathing apparatus (SCBA). A portable respiratory protective device, normally
						designed to be worn by the user by means of an incorporated harness assembly,
						with its own supply of air, oxygen or oxygen generating material. It is
						normally equipped with a full facepiece. Self-contained breathing apparatus is
						further described in 30 CFR Chapter 1, Part 11 , Subpart H.
(B) Closed-Circuit Self-Contained Breathing
						Apparatus. A device in which exhaled breath is scrubbed of
						CO2 and recycled.
(C) Open-Circuit Self-Contained Breathing
						Apparatus. A device in which compressed air is released to the face piece from
						a storage cylinder, and exhaled air is expelled to the atmosphere. (Oxygen
						supply is not permitted in open-circuit breathing apparatus used in fire
						fighting activities.)
(D)
						Demand-Type Breathing Apparatus. Equipment in which pressure inside the
						facepiece is slightly negative on inhalation, and positive on
						exhalation.
(E) Positive-Pressure
						Type Breathing Apparatus. Equipment in which the pressure inside the facepiece
						is positive during both inhalation and exhalation.
(F) Combination Breathing
						Apparatus-Respirator. A combination of compressed air self-contained breathing
						apparatus and National Institute of Occupational Safety and Health (NIOSH) Type
						C supplied-air respiratory protective device of the positive-pressure type.
Combination respirator equipment is further described
						  in 30 CFR, Chapter 1, Part 11 , Subparts H and J.
Self-Extinguishing. A term applied to a material which
						  when subjected to flaming ignition, may ignite and propagate only until removal
						  of the source of ignition.
Service Time. The period of time that a respirator has
						  been rated by NIOSH to provide protection to the wearer.
Structural Fire Fighting. The activities of rescue,
						  fire suppression, and property conservation due to a fire or emergency
						  situation involving building(s), enclosed structure(s), vehicle(s), marine
						  vessel(s), or like properties.
Training. The process of making proficient through
						  instruction and hands-on practice in the operation of equipment, including
						  respiratory protection equipment, that is expected to be used and in the
						  performance of assigned duties.
Wildlands. Sparsely populated geographical areas
						  covered primarily by grass, brush, trees, crops, or combination thereof.
Wildland Fire Fighting. The activities of fire
						  suppression and property conservation in woodlands, forests, grasslands, brush,
						  prairies, and other such vegetation, or any combination of vegetation, that is
						  involved in a fire situation, but is not within buildings or structures.
Wildland Urban Interface (WUI). The zone of transition
						  between unoccupied land and human development. It is the line, area or zone
						  where structures and other human development meet or intermingle with
						  undeveloped wildland or vegetative fuels. Communities adjacent to and
						  surrounded by wildland are at varying degrees of risk from
						  wildfires.
