The Committee approved the minutes from the NFPA 51B ROP meeting. 6. The Committee reviewed and took actions on all Public Comments (2) to NFPA 51B and developed one (1) committee comment. Additionally, the Committee discussed changing the time that a fire watch is needed to review an area after the completion of hot work activity from 30 minutes to an hour. However, the Committee did not make any changes during this stage in the cycle, as it would not give the industry enough time to review the new concept. 7. The Committee approved a motion directing the Staff to prepare and distribute the NFPA 51B ROC letter ballot. 8. The Committee discussed having the CSB involved with the future revision cycles of NFPA 51B and to develop strategies on educating the users about hot work safety. 9. Next Meeting. The next meeting will be scheduled as needed. Details will be forwarded as they become available. 10. The Chair thanked everyone for their input.

11 Attachment D Public Inputs Page 11 of 76

12 Public Input No. 17-NFPA 51B-2015 [ Global Input ] 3.3.X Responsible Party. The building owner, a lessee, or a duly authorized representative. Globally change "management" everywhere it appears in the document to "responsible party." Statement of Problem and Substantiation for Public Input Management is not defined and is a very nebulous term that could indicate anyone from the shift manager at a local McDonalds to the CEO of a Fortune 100 company. Since the term management cannot be pinned to any one person, it is unenforceable. It could apply directly to no one and to everyone. This public input suggests changing it to "responsible party" and defining that term using the language from NFPA 1. Defining responsible party prevents having to say building owner, lessee, or designated representative every time "management" appears in the document.

14 Public Input No. 44-NFPA 51B-2016 [ Section No ] This standard shall specifically not apply to the following: (1) Candles (2) Pyrotechnics or special effects (3) Cooking operations (4) Electric soldering irons (5) Design and installation of gas cutting equipment and welding equipment covered in NFPA 51, Standard for the Design and Installation of Oxygen Fuel Gas Systems for Welding, Cutting, and Allied Processes (6) Additional requirements for hot work operations in confined spaces (7) Lockout/tagout procedures during hot work Statement of Problem and Substantiation for Public Input Section states applicability of the standard and in item (8) states this it applies to "similar applications." Section elaborates on item (8) in listing application to which it does not apply. By adding the word "specifically," it emphasizes the intent more clearly. I eliminates the attempt to argue that item (8) may be interpreted to include the items in 1.3.2, nor that the definition of "Hot Work" in includes these specific applications.

28 Public Input No. 48-NFPA 51B-2016 [ Section No ] Management shall ensure that only approved listed and properly maintained apparatus, such as torches, manifolds, regulators or pressure-reducing valves, and acetylene generators, are used. Statement of Problem and Substantiation for Public Input Reason Statement: How is management to ensure that an equipment item is approved for use? Relying on a listing for the design and testing of the equipment from the manufacturer and the listing organization enables management to accomplish this task and eliminates the judgment required to determine if an equipment item is approved or not. It is also important that management ensure the listed equipment has been maintained properly prior to using in a hazardous operation.

44 Public Input No. 39-NFPA 51B-2016 [ New Section after 5.3 ] Preparing Nonpermissible Areas for conversion to Permissible Areas to for allow safe hot work In building areas where automatic sprinkler protection is impaired, removal of combustible loading (contents/construction) or complete isolation of said combustibles with a 30-minute fire rated barrier within the proposed hot work area applying the minimum 35-ft space separation rule, is required. Clean and remove all flammable gas, flammable/combustible liquid, and/or combustible dust from the proposed hot work area following the minimum 35-ft space separation rules. Isolate potential sources of flammable gas, flammable/combustible liquid, and/or combustible dust/lint that may be released into the hot work area during work. Inert any exposed tanks, vessels, or piping systems. Conduct a job safety analysis to identify sources of these materials, and to determine the appropriate isolation method. Statement of Problem and Substantiation for Public Input There are going to be situations where hot work must be done within Nonpermissible Areas which then will require necessary actions to prepare such environments to allow hot work to be conducted safely. Omitting these requirements from 51B by simply mandating that hot work cannot be done in these areas, invites the public to ignore what can be viewed as an impractical standard resulting in improper hot work within environments that will represent severe risk to human life and property.

45 Public Input No. 38-NFPA 51B-2016 [ Section No. 5.3 ] 5.3 * Nonpermissible Areas. Hot work shall not be permitted in the following areas: (1) In areas not authorized by management (2) In sprinklered buildings where sprinklers are impaired, unless the requirements of NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, are met (3) In the presence of explosive atmospheres (i.e., where mixtures of flammable gases, vapors, liquids, or dusts with air exist) (4) In the presence of uncleaned or improperly prepared equipment, drums, tanks, or other containers that have previously contained materials that could develop explosive atmospheres (5) In areas with an accumulation of combustible dusts that could develop explosive atmospheres Statement of Problem and Substantiation for Public Input The referenced requirements in NFPA 25 (section 15) currently noted in NFPA 51B section 5.3, are vague and open to wide interpretation as to what conditions represent allowable/acceptable risks from hot work operations within buildings with impaired automatic sprinkler protection (see copied/highlighted sections from NFPA ). It is proposed to strike these NFPA 25 references from NFPA 51B and replace them with a section following addressing proper preparation of Nonpermissible areas due to impaired automatic sprinkler protection to convert the area to a Permissible hot work environment. NFPA 25 Referenced Sections Measures shall be taken during the impairment to ensure that increased risks are minimized and the duration of the impairment is limited Before authorization is given, the impairment coordinator shall be responsible for verifying that the following procedures have been implemented: (1) The extent and expected duration of the impairment have been determined. (2) The areas or buildings involved have been inspected and the increased risks determined. (3) Recommendations to mitigate any increased risks have been submitted to management or the property owner or designated representative. (4) Where a fire protection system is out of service for more than 10 hours in a 24-hour period, the impairment coordinator shall arrange for one of the following: (a) Evacuation of the building or portion of the building affected by the system out of service (b)*an approved fire watch (c)*establishment of a temporary water supply (d)*establishment and implementation of an approved program to eliminate potential ignition sources and limit the amount of fuel available to the fire A (4)(d) Depending on the use and occupancy of the building, it could be enough in some circumstances to stop certain processes in the building or to cut off the flow of fuel to some machines. It is also helpful to implement No Smoking and No Hot Work (cutting, grinding, or welding) policies while the system is out of service because these activities are responsible for many fire ignitions.

56 Public Input No. 41-NFPA 51B-2016 [ New Section after 5.5 ] Hot Work Area Monitoring Following the completion of the established fire watch time period, provide fire monitoring within the hot work area for up to an additional 3-hours. A The provision of additional hot work area monitoring should be determined based on conditions that will support hidden, smoldering fire conditions such as combustible construction, storage of bulk materials such as baled waste paper or piled trash, concealed spaces within building construction. Hot work area monitoring may be provided by: personnel working in the area; automatic smoke detection; security or maintenance rounds through the hot work area every 30-minutes; security cameras with smoke or fire detection capability. Statement of Problem and Substantiation for Public Input FM Global loss history has shown that most hot work fires either start during the hot work activity or one hour or more after the hot work has been completed. In hot work fires where the fire has broken out more than one hour following the completion of hot work, the extent and severity of these fire incidents has often been far greater than other hot work caused fire incidents. With the financial challenge of maintaining fire watch personnel within the hot work area well beyond the completion of hot work activities, the provision of effective area fire monitoring will provide early warning of undetected smoldering fire conditions following the completion of the fire watch allowing for prompt manual response.

57 Public Input No. 40-NFPA 51B-2016 [ Section No ] A fire watch shall be maintained for at least 1 2 hour after completion of hot work operations in order to detect and extinguish smoldering fires. The duration of the fire watch shall be extended if the PAI determines the fire hazards warrant the extension. Similarly, the duration of the fire watch can be reduced to ½ hour where the PAI determines the fire hazards warrant that reduction. Statement of Problem and Substantiation for Public Input FM Global loss history has shown that most hot work fires either start during the hot work activity or one hour or more after the hot work has been completed. Establishing the minimum fire watch time period at one hour raises the awareness with the PAI of the potential fire risks involved if consideration of a reduced fire watch time period less than the established minimum is determined to be allowable. It is believed this proposed change will improve the quality of PAI decisions relative to the authorized fire watch time period.

60 Public Input No. 21-NFPA 51B-2015 [ Section No. A.4.1 ] A.4.1 The committee recognizes that management the responsible pary might not always have expertise in hot work and, therefore, would need a knowledgeable designated agent or contractor to act on its behalf. Examples of those who might not have the expertise can include owners of small retail shops, a small apartment complex manager, or a grocery store owner who has no knowledge of hot work safe practices. Management The responsible party should ensure that the contractor has evidence of financial responsibility, which can take the form of an insurance certificate or other document attesting to coverage or responsibility.
