specially trained to perform technical rescues, and may serve as the rapid intervention crew (RIC)
Cardiovascular disease ANS - The leading cause of firefighter fatalities.
Protecting-self when treating medical patients ANS - Limit necessary physical contact, maintain the
recommended separation distance, always were appropriate protective clothing and equipment, and
use body substance isolation (BSI) methods to treat all patients.
Public Alerting Systems ANS - Modern 9-1-1 capabilities now include text messaging and application
software (apps) for smartphones.
Local Protocol Information ANS - - Type of emergency
- Location of emergency
- THE NUMBER AND LOCATION OF PEOPLE INVOLVED
- The name and location of people involved
- The caller's callback number
Radio Communication Best Practices ANS - - Know what you are going to say before opening mic
- Use a moderate rate of speaking
- Be concise and to the point
- DO NOT TRANSMIT UNTIL THE RADIO FREQ. IS CLEAR
,Type IV Construction ANS - Heavy Timber
- columns, beams, joists, and girders
- extremely stable and resistant to collapse
- High concentration of wood can contribute to intensity of fire
- Collapse of masonry can be caused by loss of integrity of timbers.
Manufactured Homes ANS - the most common type of factory-built homes, almost completely
prefabricated prior to delivery, and the least expensive.
Space Between Floor/Ceiling & Ceiling/Roof may contain ANS - - Duct work or open return air plenum
- ELECTRICAL WIRING
- Water or natural gas pipes
- Pipes for a fire suppression system
Recessed lighting and audio speakers
- Fiberglass, cellulose, or foam insulation beneath the roof or under the floors to act as soundproofing
Door Control ANS - Firefighters should control the doors on protected stairs to maintain the integrity of
the stairwell. Sometimes securing stairway doors open may facilitate either ventilation of the structure
or evacuation of occupants
Pitched Roofs ANS - Among the most common are those elevated in the center along a ridge line with a
roof deck that slopes down to the eaves along the roof edges.
Gusset Plates ANS - Metal or wooden plates used to connect and strengthen the joints of two or more
separate components (such as metal or wooden truss components or roof or floor components) into a
load-bearing unit.
Sliding doors ANS - never allowed as a part of means of egress because they slow the travel of people
through the door opening.
Glass doors ANS - either framed or frameless
, - Frameless: single sheet of glass to which hardware such as handles are attached.
- Framed: the glass is placed in and surrounded by a metal or wood frame with the required door
hardware attached to the frame.
Window Frame ANS - includes the members that form the perimeter of a window, and it is fixed to the
surrounding wall or other supports.

Sash ANS - fixed or movable framed unit that may be included within a window frame
Sill ANS - The lowest horizontal member of the window frame and supports the weight of the hardware
and sash
Piloted Ignition ANS - the most common form of ignition. and occurs when a mixture of fuel and oxygen
encounter an external heat source with sufficient heat or thermal energy to start the combustion
reaction
HCN ANS - 35 times more toxic than CO. Acts as a chemical asphyxiant but with a different mechanism
of action than CO. Prevents the body from using oxygen at the cellular level. Can be inhaled, ingested, or
absorbed into the body.
Conduction ANS - the transfer of heat through and between solids. Occurs when a material is heated as
a result of direct contact with a heat source.
PPE reaction to heat ANS - Convected and radiated heat will begin to heat the exterior of your PPE. The
longer you are in the heated environment, the more heat that surface will absorb. The PPE has low
thermal conductivity, so it will conduct heat slowly. However, eventually the interior surface of the PPE
will heat to the same level as the exterior. Wherever the gear is compressed against skin or
underclothing, heat will be conducted faster.
PPE reaction to heat 2 ANS - Where the PPE is not in contact, it will radiate heat into the insulating air
layer between your body and the interior surface of the gear. This transferred heat can cause heat stress
and will eventually cause PPE to fail. The heat absorption and build-up in PPE is a direct result of all the
heat transfer methods acting at the same time.
