51 7 of 66 5/18/2015 1:01 PM Second Revision No. 62-NFPA [ Section No ] * For equipment in which solvent is ordinarily For equipment in which solvent is heated heated above ambient temperatures in washing or drying to a temperature that allows the solvent vapor concentration to equal or exceed 25 percent of the LEL, the electrical equipment and wiring shall be designed to greater than 16.7 C (30 F) below the flash point, in the drying phase the electrical components and wiring on such equipment shall be in accordance with NFPA 70 Class I Division 2, except as permitted in Supplemental Information File Name A docx Description Organization: National Fire Protection Assoc Submittal Date: Wed Apr 01 16:44:56 EDT 2015 Committee Statement: Response Message: The committee recognized that there is no data showing that maintaining temperatures less than 30 degrees below the flashpoint keeps LEL concentrations to less than 25%. The more critical issue is the LEL therefore the requirements for electrical equipment are tied into the temperature at which the solvent reaches 25% LEL concentration rather than to the 30 degrees below the flashpoint. Annex material has been added to explain the requirement.

52 A Each solvent has a temperature at which vapor concentrations are produced that reach 25% of the LEL for that solvent. Either the solvent manufacturer should provide the equipment manufacturer with the temperatures that causes that solvent to reach 25% of the LEL or the equipment manufacturer should test the solvent to determine this temperature. The equipment that is approved for the solvent would have the ability to control the heating of the solvent to a level below 25% of the LEL based on the solvent that is approved for use in the machine. Equipment does not necessarily require an LEL measuring device.

53 8 of 66 5/18/2015 1:01 PM Second Revision No. 63-NFPA [ Sections , ] The electrical equipment and wiring on equipment without stills shall be in accordance with NFPA 70, and contain as long as it contains instrumentation, equipment systems, or controls that are active in washing or drying that provide any one or combination of the following: (1) Features that limit oxygen concentrations to less than 8 percent by volume (2) Features that limit solvent vapor concentration to less than 25 percent of the LEL (3)* Features that limit solvent vapor concentration at or below 60 percent of the LEL where automatic instrumentation with safety interlocks is provided in accordance with NFPA The electrical equipment and wiring on equipment with stills shall be in accordance with NFPA 70, and contain instrumentation, equipment, or controls that can automatically de-energize equipment if the Visual and audible alarm devices and automatic shutdown of non-safety related components shall be provided to de-energize equipment if its integrity of the still has been compromised and is not functioning as designed. Organization: National Fire Protection Assoc Submittal Date: Wed Apr 01 17:01:22 EDT 2015 Committee Statement: Response Message: These changes were made to clarify that safety features are working during the correct portion of a drycleaning cycle.

58 3 of 66 5/18/2015 1:01 PM Second Revision No. 43-NFPA [ Section No ] * A Where carbon dioxide storage tanks are installed inside buildings, a listed gas detection system with an audible local alarm shall be installed in indoor storage areas and used to notify the building occupants if the a leak of carbon dioxide concentration reaches an unsafe level occurs. Supplemental Information File Name A docx Description Submittal Date: Thu Mar 19 16:08:32 EDT 2015 Committee Statement: Response Message: It is difficult to determine what an "unsafe level" of CO2 would be and this language is vague and unenforceable. The concern is with any leak of CO2. Annex material was added to further explain where gas detectors should be installed.

59 A Consideration shall be given to the possibility of carbon dioxide drifting and settling into adjacent places outside of where the carbon dioxide is used. A detection system should also be installed in that location.
