Iowa Administrative Code › Agency 661 - Public Safety Department › Chapter 275 - Licensing of Fire Protection System Contractors › Rule 661-275.2 - Definitions

Current through Register Vol. 47, No. 3, July 24, 2024
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.
