The following definitions apply:
"Aerosol fire extinguishing system" means a
system that uses a combination of microparticles and gaseous matter to flood
the protected area. The particles are in a vapor state until discharged from
the device. On release, a chain reaction produces solid particles and gaseous
matter to suppress the fire.
"Automatic dry-chemical extinguishing system"
means the same as defined in Iowa Code section
100C.1(4).
"Automatic fire extinguishing system" means
the same as defined in Iowa Code section
100C.1(5).
"Automatic sprinkler system" means the same as
defined in Iowa Code section
100C.1(6).
"Carbon dioxide extinguishing system" means
the same as defined in Iowa Code section
100C.1(7).
"Clean agent" means an electrically
nonconducting, volatile, or gaseous fire extinguishant that does not leave a
residue upon evaporation.
"Deluge system" means the same as defined in
Iowa Code section 100C.1(8).
"Dry chemical" means a powder composed of very
small particles, usually sodium bicarbonate-, potassium bicarbonate-, or
ammonium phosphate-based, with added particulate material supplemented by
special treatment to provide resistance to packing, resistance to moisture
absorption (caking), and the proper flow capabilities.
"Dry pipe sprinkler system" means an
extinguishing system employing automatic sprinklers that are attached to a
piping system containing air or nitrogen under pressure, the release of which
(as from the opening of a sprinkler) permits the water pressure to open a valve
known as a dry pipe valve, which allows the water to flow into the piping
system and out the opened sprinklers.
"Fire extinguishing system contractor," "fire
protection system contractor," or "contractor" means
the same as defined in Iowa Code section
100C.1(10).
"Foam extinguishing system" means the same as
defined in Iowa Code section
100C.1(11).
"Halogenated extinguishing system" means the
same as defined in Iowa Code section
100C.1(12).
"Hybrid-inert water mist system" means a
system that combines the benefits of inert gas systems and water mist systems
to extinguish fires. These systems provide both extinguishment and cooling to
prevent reignition utilizing nontoxic, non-ozone-depleting hybrid media.
"Layout" means drawings, calculations and
component specifications to achieve the specified system design installation.
"Layout" does not include design.
"Listed" means equipment, materials, or
services included in a list published by a nationally recognized independent
testing organization concerned with evaluation of products or services that
maintains periodic inspection of production of listed equipment or materials or
periodic evaluation of services and whose listing states that either the
equipment, material, or service meets appropriate designated standards or has
been tested and found suitable for a specified purpose.
"Maintenance inspection" means the same as
defined in Iowa Code section
100C.1(13).
"Preengineered dry chemical or wet agent fire
suppression system" means any system having predetermined flow rates,
nozzle pressures and limited quantities of either agent. These systems have
specific pipe sizes, maximum and minimum pipe lengths, flexible hose
specifications, number of fittings and number and types of nozzles prescribed
by a nationally recognized testing laboratory. The hazards against which these
systems protect are specifically limited by the testing laboratory as to the
type and size based upon actual fire tests. Limitations on hazards that can be
protected against by these systems are contained in the manufacturer's
installation manual, which is referenced as part of the listing.
"Preengineered water-based system" means a
packaged, water-based sprinkler system including all components connected to a
water supply and designed to be installed according to pretested
limitations.
"Responsible managing employee" means the same
as defined in Iowa Code section
100C.1(14).
"Special hazards system" means a fire
extinguishing system utilizing fire detection and control methods to release an
extinguishing agent, other than water connected to a dedicated fire protection
water supply.
"Wet agent" or "wet chemical"
means an aqueous solution of organic or inorganic salts or a combination
thereof that forms an extinguishing agent.
