Scope, Purpose, and <br />Limitations <br />Sec. 9.101 Purpose <br />This standazd describes a low-cost <br />automatic sprinkler system which <br />will contribute to the reduction of <br />loss of life and property damage by <br />fire currently experienced in resi- <br />dences. <br />Sec. 9.102 Scope <br />This standazd describes the require- <br />ments for the mechanical and perfor- <br />mance properties of the sprinkler <br />itself. It also describes the require- <br />ments for the installation of the <br />complete sprinkler system for one to <br />fifteen family dwelling units (not <br />exceeding 12,000 sf in any one <br />building) and UBC Standazd 9-1 for <br />all other occupancies. <br />Sec. 9.104 Limitations <br />This standazd is intended to describe <br />a suppression system which can <br />maintain a tenable environment for a <br />period of ten (10) minutes following <br />the operation of the sprinkler. <br />Persons in direct proximity to the <br />fire may not benefit from the sup- <br />pression portion of the sprinkler <br />system, nor will persons suffering <br />ancillary injuries or those that aze <br />nonambulatory or in the state of <br />panic reaction to the fire emergency. <br />This standard permits omission of <br />sprinklers in certain areas in which <br />fires are statistically unlikely to <br />originate and in azeas of low com- <br />bustible loading. Fires starting in the <br />above type of area will be uncon- <br />trolled except eventually by an out- <br />side agency. <br />'700_ 1 (Pleasanton April 2000) <br />
