' Car ill Fresh Water Biolo ical Institute <br /> g g <br /> 6/11/98,page 2 <br /> ' 3.0 FLAMMABLE LI UIDS STORAGE/USE ROOM <br /> Q <br /> ' The room used for storage and use is proposed as a Group H-3 Occupancy and the laboratory is <br /> classified as a Group B Occupancy per the UBC. The entire building is not protected with an <br /> automatic sprinkler system. The flammable liquid space is currently provided with a disabled <br /> ' CO2 suppression system,which will require maintenance and a total engineering review of <br /> calculations for the increased area before activation. Therefore,the system will be removed and <br /> the room will be protected by an automatic sprinkler system. The room is required by code to be <br /> ' protected with a suppression system,which is capable of protecting high hazard storage of Class <br /> I-B liquids. The calculations and recommendations for the suppression system are included in <br /> this report and will need to be designed to the final use and storage configuration of the space. <br /> ' Article 79 of the Uniform Fire Code allows a maximum exempt amount of Class I-B liquid <br /> storage that is not in a building protected with an automatic suppression system of 60 gallons. In <br /> ' addition,Article 79 allows a maximum exempt amount of 15 gallons of a Class I-B liquid for <br /> open use operations. With these restrictions,the proposed amount of storage and dispensing,and <br /> the recommendations found in this section the space is being proposed as an H-3 occupancy. <br /> ' Under Section 904 of the UBC,all H-3 occupancies are required to have a complete automatic <br /> suppression system. This system can be a water sprinkler system or other approved automatic <br /> fire-extinguishing protection, such as CO2. The use of a water-based system may be the least <br /> � expensive for initial installation_but it�vill � � req�irerr�e�is fer the rt�om as <br /> outlined below. The installation of the CO2 system may provide the least impact on the room <br /> requirements,but it may not be desirable if the room is occupied during normal operation for <br /> ' staff safety. A total flooding alternate agent suppression system is the safest option,but requires <br /> additional up-front costs for its installation and design. For this project, a sprinkler system will <br /> be installed. <br /> ' It is the intent of Cargill, and MountainStar to restrict operations in the storage room in <br /> order to maintain an H-3 Occupancy classification. Because of the proposed dispensing <br /> ' that will occur MountainStar is recommending the following to facilitate an H-3 <br /> Occupancy classification. <br /> ' 1. Any dispensing shall be from or into containers that are 15 gallons or less. <br /> 2. Any dispensing from containers larger than 15 gallons must be done using a <br /> hand pump or nozzle or other device that is normally closed and requires <br /> ' constant pressure/force to remain in an open condition. <br /> 3. Cargill has proposed that the presence of a waste container inside the storage <br /> room. This container may either be 15 gallons or less, or must be filled using <br /> ' a pump or other system from containers smaller than 15 gallons. The intent is <br /> to limit the amount of hazardous liquid that is open to the atmosphere too less <br /> than 15 gallons. <br /> , The storage room is re uired to meet all re uirements for an H-3 occu anc in the State Buildin <br /> 9 q P Y g <br /> Code(UBC)and are outlined below: <br /> ' <br /> 1 <br /> ' <br />
