DIVISION 4. HAZARD OF BUILDINGS
SECTION 10.2.4.1
GENERAL
A. For purposes of this Chapter, the degree of hazard shall be the relative
danger of the start and spread of fire, the generation of smoke or gases,
the danger of explosion or other occurrences potentially endangering
the lives and safety of the occupants of the building or structure due to
the nature of the contents or processes/operations therein.
B. The degree of fire hazard shall be determined by the City/Municipal Fire
Marshal having jurisdiction on the basis of the nature, character of the
contents and the process or operations being conducted in the building
or structure: Provided, however, that where the flame spread rating of
the interior finish or other features of the building or structure are such as
to involve a fire hazard greater than the hazard of contents, the greater
degree of fire hazard shall govern, except if such hazardous areas are
segregated or protected as specified in Section 10.2.6.8 of this IRR and
the applicable sections of Divisions 8 through 17 of this Chapter.
SECTION 10.2.4.2
CLASSIFICATION OF HAZARD OF CONTENTS
A. The hazard of contents of any building or structure shall be classified as
follows:
1. Low Hazard
Those of such low combustibility that no self-propagating fire therein
can occur and that consequently, the only probable danger requiring
the use of emergency exits will be from panic, fumes or smoke or fire
from some external source.
2. Moderate Hazard
Those which are liable to burn with moderate rapidity or to give off a
considerable volume of smoke but from which neither poisonous
fumes nor explosions are to be expected in the event of fire.
3. High Hazard
Those which are liable to burn with extreme rapidity or from which
poisonous gases or explosions are to be expected in the event of fire.
