8 DRAFT MINUTES OF NFPA 484 Pre-ROP MEETING - A new steel/iron chapter needs to be introduced before ROP meeting. - Insert low hazard material into Chapter NFPA 400 MAQ Limits: Isolated key issues. Flammable solids: MAQ = 125 lbs.; currently no formal proposals. Redirect to NFPA 484 (need footnote in NFPA 400 table for metals). Need to clarify NFPA Literary Review: Tabled until Chapter 14 new material is presented. 4. Advisory Service Inquiries: - Lithium battery storage to be addressed under New Business.

Dust/powder distinction loss in the chapter. TG (Tim M. & Kevin K) - Specific chapters will be performed individually. Two items, clarification & errors. - To provide Word 484 documents to all individuals involved. - Items to be posted on our website. Reports, documents, etc. f. Discussion of how/if the standard should address metals that are combustible but NOT explosive. - Any changes needed to NFPA 484? - Literary review TG: Change scope and Chair from Mark Drake to Elizabeth Buc. (Elizabeth added to TG.) g. Identification of other Held or carryover material/discussions from the last revision. - Reference NFPA 2113 for clothing and consistencies throughout Standard - Peter D, Recycling Chapter 16 document: Identify misunderstandings. - Fires usually involve dirty metals (mixed with other materials) - Definition maybe needed - Need incoming QA/QC (need waste analysis plan) reject that material which does not meet qualifications - No hazard analysis requirements are provided h.

13 From: To: Subject: Date: Goyette, Joanne Goyette, Joanne FW: Compressed Air Cleaning Friday, March 09, :36:51 PM From: Christman, Tom Sent: Wednesday, March 07, :14 PM To: Drake, Mark; Curtis, Martha; Cc: 2elks Subject: Compressed Air Cleaning An issue that needs to be reviewed. Some chapters allow for compressed air cleaning and other chapters don t. Here is 10 and 8 is the same: Compressed Air Cleaning Requirements. Compressed air blowdown shall not be permitted, only except in certain areas that are otherwise impossible to clean by vacuuming or other means and, where permitted, shall be performed under carefully controlled conditions with all potential ignition sources prohibited in or near the area and with all equipment shut down. Here is Chapter 9: Compressed-air blowdown shall not be permitted. Chapter 11 is mixed, one section permits it and another within the chapter prohibits it: Compressed Air Cleaning Requirements. Compressed air blowdown shall not be permitted, only except in certain areas that are otherwise impossible to clean by vacuuming or other means and, where permitted, shall be performed under carefully controlled conditions with all potential ignition sources prohibited in or near the area and with all equipment shut down Vigorous sweeping or blowing down with compressed air produces dust clouds and shall be permitted only where the following requirements are met: (1) Electrical equipment not suitable for Class II, Group E locations and other sources of ignition shall be shut down or removed from the area. (2) Compressed air shall not exceed a gauge pressure of 206 kpa (30 psi), unless otherwise determined to be safe by a documented hazard analysis.

14 Blowing down of any surfaces by compressed air shall be prohibited. It looks like 12 and 13 don t address the specifics: Cleaning methods shall be limited to those methods that minimize the probability of causing a fire or explosion, as determined by a person knowledgeable in the properties of titanium dust See for additional requirements Cleaning methods shall be limited to those methods that minimize the probability of causing a fire or explosion, as determined by a person knowledgeable in the properties of zirconium dust. Here is 14: Housekeeping. Housekeeping shall be in accordance with Well not so fast, 14 also states: Compressed-Air Cleaning Requirements. Compressed-air blowdown shall not be permitted, unless the conditions of are met In certain areas that are otherwise impossible to clean, compressed-air blowdown shall be permitted under controlled conditions with all potential ignition sources prohibited in or near the area and with all equipment shut down. Here is the 15 material: Compressed-Air Cleaning Requirements Compressed-air blowdown shall not be permitted, unless the conditions of are met In certain areas that are otherwise impossible to clean, compressed-air blowdown shall be permitted under controlled conditions with all potential ignition sources prohibited in or near the area and with all equipment shut down. And the IFC doesn t allow it. Here is the wording from 2006 IFC: Housekeeping. Accumulation of combustible dust shall be kept to a minimum in the interior

15 of buildings. Accumulated combustible dust shall be collected by vacuum cleaning or other means that will not place combustible dust into suspension in air. Forced air or similar methods shall not be used to remove dust from surfaces. Here is the wording from NFPA 1: * Dust Clouds Surfaces shall be cleaned in a manner that minimizes the generation of dust clouds. [654: ] Vigorous sweeping or blowing down with steam or compressed air produces dust clouds and shall be permitted only where the following requirements are met: (1) Area and equipment shall be vacuumed prior to blowdown. (2) Electrical equipment not suitable for Class II locations and other sources of ignition shall be shut down or removed from the area. (3) Only low-pressure steam or compressed air, not exceeding a gauge pressure of 15 psi (103 kpa), shall be used. (4) No hot surfaces or flames capable of igniting a dust cloud or layer shall exist in the area. [654: ] So now there is also an inconsistency with the allowed pressure when compressed air is permitted. This could be a lively discussion. Just noticed it in the process of getting my presentation together for Gallatin, TN next week. tom
