Type ILIA—as systems using Class 111A solvents. NFPA 3.3.18 Systems—Identified in 3.3.18.3 Type IIIA-Systems employing Class 1114 solvent and eomplying with Chapter 4, 5, 6, and 8. 1FC 1207—Drycleaning systems 1247.1 General-Drycleaning systems including units....... shall be installed and maintained in accordance with NPFA 32. The construction of building in which such systems are located shall comply with this section and IBC. 1FC 1208—Fire protection 1208.1 General- .......... shall be in accordance with Chapter 9 1248.2 Automatic Sprinkler System-an automatic sprinkler shall be in accordance with Section 903.3.1.1 throughout drycleaning plant containing Type II,IIIA,or IIIB drycleaning systems. The most obvious difference between the two code standards of IFC and NFPA is that requirements set forth are either Prescriptive(IFC) or Performance(NFPA). In both standards the intent of safety is recognized. The Columbia TL HCS IPURA system is a closed circuit, dry to dry machine and self contained_ This means dry garments are placed into the machine for cleaning and the operator can only start the cycle once the loading door is closed and pneumatically locked. The washing and drying of the work loads can then be executed in an automatic cycle or manual cycle to its completion. When the cycle is finished,the operator will be able to unlock the door and remove dry garments. There is no combustible liquid or vapor present in the ambient of the work(control) area around the machine at anytime. This system is quite different from systems known as"Transfer",where as washing is done in one machine, and the operator must remove wet garments to place there in another unit for drying the garments. In this case combustible vapor and liquid is present in the ambient work(control) area of the equipment. NFPA recognizes the difference of operating equipment within its' scope, and allows for certain building requirements to be relaxed based on the level of hazards that exist in each application;the code standards in IFC uses the higher potential of hazards such as transfer systems and lower flash point liquids and couples them to the least potential of hazards such as closed circuit system with higher flash points and safety controls. Therefore, the following sections of NFPA,32 address the intent of safety in response to the specific equipment configuration and its' control area. 8.1.2.1 —Separation—Type I11A drycleaning plants located in building with other occupancies shall be separated from other occupants by a fire barrier haying a 2 hours minimum fire resistant rating.
