ESSENTIALS OF FIRE FIGHTING 7TH
EDITION 2026 QUESTIONS AND ANSWERS
ALL CHAPTERS GRADED A+
⩥ All-Hazard Concept. Answer: Provides a coordinated approach to a
wide variety of incidents; all responders use a similar, coordinated
approach with a common set of authorities, protections, and resources.
⩥ Atypically Stressful Event. Answer: Term used in National Fire
Protection Association (NFPA) standards to describe incidents that have
a likelihood of causing critical incident stress.
⩥ Battalion. Answer: Fire department organizational subdivision
consisting of several fire service companies in a designated geographic
area. A battalion is usually the first organizational level above individual
companies or stations.
⩥ Body Substance Isolation (BSI). Answer: Comprehensive method of
infection control in which every patient is assumed to be infected;
personal protective equipment is worn to prevent exposure to bodily
fluids and blood-borne and airborne pathogens.
⩥ Carcinogen. Answer: Cancer-producing substance.
,⩥ Chain of Command. Answer: Order of rank and authority in the fire
and emergency services.
⩥ Chronic. Answer: Long-term and reoccurring.
⩥ Chronic Obstructive Pulmonary Disease (COPD). Answer: Term for
several diseases that result in obstructive problems in the airway.
⩥ Code. Answer: a collection of rules and regulations that has been
enacted by law in a particular jurisdiction. Codes typically address a
single subject area; examples include a mechanical, electrical, building,
or fire code.
⩥ Code Enforcement. Answer: Process of enforcing a body of law aimed
at reducing fire and life-safety hazards as well as mandating the prober
installation and maintenance of building/structure fire and life-safety
features to provide adequate community fire prevention.
⩥ Cold Zone. Answer: Safe area outside of the warm zone where
equipment and personnel are not expected to become contaminated and
special protective clothing is not required; the incident command post
and other support functions are typically located in this zone.
⩥ Community Risk Reduction (CRR). Answer: The Fire Department's or
other agency's identification and prioritization of risks to the community
,followed by integrated application of resources to improve public safety
through minimizing the probability or occurrence and/or the impact of
unfortunate events.
⩥ Company. Answer: Basic fire fighting organizational unit consisting
of firefighters and apparatus; headed by company officer.
⩥ Culture. Answer: The shared assumptions, beliefs, and values of a
group or organization.
⩥ Generator. Answer: Portable device for generating auxiliary electrical
power; generators are powered by gasoline or diesel engines and
typically have 110- and/or 220-volt capacity outlets.
⩥ Ground Fault Circuit Interrupter (GFCI). Answer: Device designed to
protect against electrical shock; when grounding occurs, the device
opens a circuit to shut off the flow of electricity.
⩥ Ground Gradient. Answer: Electrical field that radiates outward from
where the current enters the ground; its intensity dissipated rapidly as
distance increases from the point of entry.
⩥ Hazard. Answer: Condition, substance, or device that can directly
cause injury or loss; the source of a risk.
, ⩥ Hot Zone. Answer: Potentially hazardous area immediately surround
the incident site; requires appropriate protective clothing and equipment
and other safety precautions for entry.
⩥ Immediately Dangerous to Life and Health (IDLH). Answer:
Description of any atmosphere that poses an immediate hazard to life or
produces immediate irreversible debilitating effects on health.
⩥ Incident Command System (ICS). Answer: Standardizing approach to
incident management that facilitates interaction between cooperating
agencies; adaptable to incidents of any size or type.
⩥ Incident Commander (IC). Answer: Person in chare of the incident
command system and responsible for the management of all incident
operations during a emergency.
⩥ Intrinsically Safe. Answer: Describes equipment that is approved for
use in flammable atmospheres; must be incapable of releasing enough
electrical energy to ignite the flammable atmosphere.
⩥ Inverter. Answer: Step-up transformer that converts vehicle's 12- or
24-volt DC current into 110- or 220-volt AC current.
⩥ Line Personnel. Answer: Personnel who provide emergency services
to external customers (the public).
