903.2.9.1 #4 Commercial Trucks and Buses

[retire09]

This requirement to provide sprinklers in repair garages for commercial trucks and buses over 5000sf is new.

I do not have a 2009 commentary and was wanting to know why this was added to the code.

Can someone explain the logic for this change?

Thanks

Automatic sprinklers may be required in repair

garages, depending on the quantity of combustibles

present, their location and floor area. In addition any

Group S-1 fire area intended for the repair of commercial

buses or trucks that exceeds 5,000 square feet

(464 m2) would require sprinklers. This is the same criteria

as Group S-1 occupancies and Group S-2

enclosed parking garages storing commercial buses

and trucks. Repair garages may contain significant

quantities of flammable liquids and other combustible

materials. These occupancies are typically considered

Ordinary Hazard Group 2 occupancies as defined in

NFPA 13. Portions of repair garages used for parts

cleaning using flammable or combustible liquids may

require automatic sprinkler protection. If quantities of

hazardous materials exceed the limitations in Section

307 for maximum allowable quantities per control

area, the repair garage would be reclassified as a

Group H occupancy.
