1 Cargill Fresh Water Biolo ical Insritute <br /> S <br /> 6/11/98,page 4 <br /> ' 14. One or more portable fire extinguishers,with minimum rating of 20-B, shall be <br /> located within 10 feet of the room door. <br /> I 4.0 LABORATORY AREA <br /> ' This section outlines current fire code requirements for protection systems and features of the <br /> building and space that are identified as the Pilot Project Area. <br /> ' This area is proposed to be used as a laboratory in the Group B Occupancy and is not provided <br /> with a hydraulically designed sprinkler system installed throughout the room or building. The <br /> maximum of Class I-B liquid that can be used in a Group B Occupancy is 60 gallons for closed <br /> ' use. The definition of a closed use system is a liquid hazardous material in a closed vessel or <br /> system that remains closed during normal operations where vapors emitted by the product are <br /> not liberated outside the vessel or system and the product is not exposed to the atmosphere <br /> ' during normal operations. <br /> The laboratory is limited to a combined total of 60 gallons of Class I-B liquid for storage and <br /> closed use and must include the following requirements for the laboratory in the Group B <br /> ' Occupancy: <br /> 1. Laboratories in buildings used for trainin and�ducational n�poS�S-andsimilar _ _ _ <br /> � areas containing hazardous materials, shall be separated from other portions of the <br /> building by not less than a one-hour fire-resistive occupancy separation. T'he doors <br /> leading to corridors shall be not less than 3/4-hour fire rated and all other openings <br /> ' shall be one-hour fire rated. <br /> 2. Two exits are required for the laboratory,with a travel distance of 75 feet or less <br /> within the laboratory. The maximum travel distance of 200 feet to an exit also <br /> ' applies. <br /> 3. The area and height limitation of Chapter 5 of the building shall be met. <br /> 4. The location of the existing building on the property and opening protection is <br /> ' assumed to meet the minimum requirements of the UBC. <br /> 5. All exit components appear to meet the minimum requirements of UBC Chapter 10. <br /> The dropped area that is identified for the laboratory and the new hood is not <br /> , provided with an accessible access. The building official will be notified via a letter <br /> requesting that the pit area be exempt from compliance with ADA requirements due <br /> to limitations for the type of work in the area that can not reasonably be performed <br /> , by a person with impairments. <br /> 6. Closed systems designed to be opened as part of the normal operation shall include a <br /> ventilation design which provides the pit with continuous ventilation at a rate of not <br /> ' less that 1 cubic foot per minute per square foot of floor area. Ventilation of the <br /> flammable vapors shall meet the minimum requirements of the State Mechanical <br /> Code. The proposed design appears not to be open and therefore will not require <br /> ' additional ventilation. <br /> 7. If the dispensing operation is relocated into the laboratory space in quantities greater <br /> than the exempt amounts(60 gallons)the following modifications will be required: <br /> ' I. All transfer operations shall be through an approved closed piping system or <br /> an approved engineered liquid transfer system. <br /> II. The transfer of liquid from the drum to the approved piping system shall be <br /> ' conducted using a positive displacement pump that will provide pressure <br /> � <br />
