� Cargill Fresh Water Biological Institute <br /> 6/11/98,page 5 <br /> ' relief discharge back to the drum, use pump suction or be provided with <br /> over-pressure relief. The transfer piping system uses a gas pressure system. <br /> � Only inert gas can be used. <br /> IIL All piping,hoses and valves used with the liquid transfer operations shall be <br /> listed or approved for the use. <br /> � N. The transfer system shall be electrically bonded between the drum and <br /> piping system. <br /> 8. The electrical classi�cation for where the flammable liquid will be transferred shall <br /> � be rated as Class I, division 2 for the entire pit area. All areas within 5 feet of any <br /> edge of any pumps,bleeders, withdrawal fittings, meters and similar devices shall be <br /> Class I, division 2 in all directions from the hazard. Since the transfer of liquids is <br /> � not to be located within the pit, all equipment within 3 feet of the floor areas, within <br /> 25 feet of the transfer pumps or similar equipment shall be protected with Class I, <br /> division 2 electrical equipment. <br /> � 9. Vehicles will be allowed for unloading and loading purposes in the pilot lab area. <br /> ' S.0 CONCLUSION <br /> Based on the supporting data and the information provided by Jafvert Mueller Architects, the <br /> proposed occupancy classi�cations of Group H-3 for the flammable liquid storage room and <br /> ' classification of Group B for the research and development area are conect in the opinion of The <br /> MountainStar Group, Incorporated. With the limitations and protection measures as outlined <br /> above, the laboratory and flammable liquid rooms will be protected in accordance with the <br /> � requirements and intent of the 1994 UBC and 1997 UFC. This report contains MountainStar's <br /> recommendations regarding the fire protection design required for dispensing and storage of the <br /> Class I-B flammable liquid in the flammable liquid storage room and for closed use and storage <br /> ' in the laboratory. <br /> This report will need to be re-evaluated, if the amount of liquid storage changes, quantity of <br /> ' liquid used in open or closed condition, liquid or hazardous material classification changes, <br /> storage arrangement is modified, or the fire rating which subdivides the space changes.
