Thanks Tom, We do have a water only system. I will go through the chart and confirm what I need. How would you determine the "expected discharge" from the sprinkler system. Dewayne

If you do then curbs without drainage is OK If you have a water only system then u will need drainage with the curbs. Review figure 6.8.5 on page 57 of NFPA 30, 2003 edition, it will indicate IF you need to provide spill containment OR liquid spread control. Curbs are used if you have a closed head foam system to control the spread of the product mixed with the water (section 6.4.2.5). If you have a water only sprinkler system and you have a Class I-IIIA liquid then, you need to provide liquid spread control as per 6.8.5.1. Take a look at FM data sheet 7-29 it has more up to date sprinkler protection requirements then NFPA 30/ 2003 edition.
