1 Assembly (see Section 303) Groups A-1 A-2 A-3 A-4 and A-5

2 Business (see Section 304) Group B

3 Educational (see Section 305) Group E

4 Factory and Industrial (see Section 306) Groups F-1 and F-2

30211 Incidental use areas Spaces which are incidental to the main occupancy shall be separated or protected or both in accordance with Table 30211 or the building shall be classified as a mixed occupancy and comply with Section 3023 Areas that are incidental to the main occupancy shall be classified in accordance with the main occupancy of the portion of the building in which the incidental use area is loshycated

Exception Incidental use areas within and serving a dwelling unit are not required to comply with this secshytion

302111 Separation Where Table 30211 requires a fire-resistance-rated separation the incidental use area shall be separated from the remainder of the building with a fire barrier Where Table 30211 permits an autoshymatic fire-extinguishing system without a fire barrier the incidental use area shall be separated by construction cashypable of resisting the passage of smoke The partitions

shall extend from the floor to the underside of the fire-resistance-rated floorceiling assembly or fire-resisshytance-rated roofceiling assembly or to the underside of the floor or roof deck above Doors shall be self-closing or automatic-closing upon detection of smoke Doors shall not have air transfer openings and shall not be unshydercut in excess of the clearance permitted in accordance with NFPA 80

TABLE 30211 INCIDENTAL USE AREAS

Exception Except for Group H and I-2 areas where the building is equipped throughout with an automatic sprinshykler system installed in accordance with Section 903311 the fire-resistance ratings in Table 30232 shall be reduced by 1 hour but to not less than 1 hour and to not less than that required for floor construction acshycording to the type of construction

COMPRESSED GAS A material or mixture of materialswhich

1 Is a gas at 68degF (20degC) or less at 147 pounds per squareinch atmosphere (psia) (101 kPa) of pressure and

2 Has a boiling point of 68degF (20degC) or less at 147 psia(101 kPa) which is either liquefied nonliquefied or in so-lution except those gases which have no other health- orphysical-hazard properties are not considered to be com-pressed until the pressure in the packaging exceeds 41psia (282 kPa) at 68degF (20degC)

The states of a compressed gas are categorized as follows

1 Nonliquefied compressed gases are gases other thanthose in solution which are in a packaging under thecharged pressure and are entirely gaseous at a tempera-ture of 68degF (20degC)

2 Liquefied compressed gases are gases that in a packag-ing under the charged pressure are partially liquid at atemperature of 68degF (20degC)

3 Compressed gases in solution are nonliquefied gases thatare dissolved in a solvent

4 Compressed gas mixtures consist of a mixture of two ormore compressed gases contained in a packaging thehazard properties of which are represented by the prop-erties of the mixture as a whole

CONTROL AREA Spaces within a building that are en-closed and bounded by exterior walls fire walls fire barriersand roofs or a combination thereof where quantities of haz-ardous materials not exceeding the maximum allowable quan-tities per control area are stored dispensed used or handled

CORROSIVE A chemical that causes visible destruction ofor irreversible alterations in living tissue by chemical action atthe point of contact A chemical shall be considered corrosive

if when tested on the intact skin of albino rabbits by the methoddescribed in DOTn 49 CFR Part 173137 such a chemical de-stroys or changes irreversibly the structure of the tissue at thepoint of contact following an exposure period of 4 hours Thisterm does not refer to action on inanimate surfaces

CRYOGENIC FLUID A liquid having a boiling point lowerthan -150degF (-101degC) at 147 pounds per square inch atmo-sphere (psia) (an absolute pressure of 101 kPa)

DEFLAGRATION An exothermic reaction such as the ex-tremely rapid oxidation of a flammable dust or vapor in air inwhich the reaction progresses through the unburned material ata rate less than the velocity of sound A deflagration can havean explosive effect

DETACHED BUILDING A separate single-story buildingwithout a basement or crawl space used for the storage or useof hazardous materials and located an approved distance fromall structures

DETONATION An exothermic reaction characterized by thepresence of a shock wave in the material which establishes andmaintains the reaction The reaction zone progresses throughthe material at a rate greater than the velocity of sound Theprincipal heating mechanism is one of shock compressionDetonations have an explosive effect

DISPENSING The pouring or transferring of any materialfrom a container tank or similar vessel whereby vapors dustsfumes mists or gases are liberated to the atmosphere

EXPLOSIVE Any chemical compound mixture or devicethe primary or common purpose of which is to function by ex-plosion The term includes but is not limited to dynamiteblack powder pellet powder initiating explosives detonatorssafety fuses squibs detonating cord igniter cord igniters anddisplay fireworks 13G (Class B Special)

Where Note f also applies the increase for both notes shall be applied accumulativelyf Quantities shall be increased 100 percent when stored in approved storage cabinets gas cabinets or exhausted enclosures as specified in the Phoenix Fire Code

Where Note e also applies the increase for both notes shall be applied accumulativelyg A single cylinder containing 150 pounds or less of anhydrous ammonia in a single control area in a nonsprinklered building shall be considered a maximum allow-

able quantity Two cylinders each containing 150 pounds or less in a single control area shall be considered a maximum allowable quantity provided the buildingis equipped throughout with an automatic sprinkler system in accordance with Section 903311
