1. The Chair opened the meeting at 1:10 p.m., October 18, 2012.

2. The Chair welcomed the Committee and asked them to consider “How can we, as in the committee, influence the awareness of the hot work hazards?”

3. Attendees introduced themselves and necessary corrections were made to the

Technical Committee roster.

4. The Staff reported on the current committee roster and member status, reviewed the general procedures, available resources from the Fire Research

Foundation, and reviewed the milestones for the revision cycle for Annual 2013. Additionally, the Staff introduced the new standards development process that will be in effect for the next revision cycle.

5. 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. The Committee Meeting was

adjourned at 3:45 p.m., on October 18, 2012.

Respectfully submitted, Derek Duval, NFPA, Staff Liaison

Public Inputs


Page 11 of 76

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.

Public Input No. 35-NFPA 51B-2016 [ Section No. 1.3.2 ]

1.3.2

This standard shall 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 AlliedProcesses

(6) Additional requirements for hot work operations in confined spaces

(7) Lockout/tagout procedures during hot work

(8) Hot works conducted in labratories compling with NFPA 45


The requirements contained in NFPA 51B are excessive and not partible for work being conducted in laboratories. In addition, NFPA 45 contains safeguards for hot works in laboratories.

1.3.2

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 AlliedProcesses

(6) Additional requirements for hot work operations in confined spaces

(7) Lockout/tagout procedures during hot work


Section 1.3.1 states applicability of the standard and in item (8) states this it applies to "similar applications." Section 1.3.2 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 3.3.1 includes these specific applications.

5.3.1 Preparing Nonpermissible Areas for conversion to Permissible Areas to for allow safe hotwork

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 ratedbarrier within the proposed hot work area applying the minimum 35-ft space separation rule, isrequired.

Clean and remove all flammable gas, flammable/combustible liquid, and/or combustible dust fromthe proposed hot work area following the minimum 35-ft space separation rules. Isolate potentialsources of flammable gas, flammable/combustible liquid, and/or combustible dust/lint that may bereleased 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 theappropriate isolation method.


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.

(4) In the presence of uncleaned or improperly prepared equipment, drums, tanks, or other containersthat have previously contained materials that could develop explosive atmospheres

(5) In areas with an accumulation of combustible dusts that could develop explosive atmospheres


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 25 2014).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 Sections15.1.1.2 Measures shall be taken during the impairment to ensure that increased risks are minimized and the duration of the impairment is limited.15.5.2 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.15.5.2(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 fuelto 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 activitiesare responsible for many fire ignitions.

5.5.4 Hot Work Area Monitoring

Following the completion of the established fire watch time period, provide fire monitoring withinthe hot work area for up to an additional 3-hours.

A.5.5.4 The provision of additional hot work area monitoring should be determined based onconditions 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 withinbuilding construction. Hot work area monitoring may be provided by: personnel working in thearea; automatic smoke detection; security or maintenance rounds through the hot work area every30-minutes; security cameras with smoke or fire detection capability.


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.

5.5.2

A fire watch shall be maintained for at least 1 ⁄ 2 hour after completion of hot work operations in order todetect and extinguish smoldering fires. The duration of the fire watch shall be extended if the PAIdetermines the fire hazards warrant the extension. Similarly, the duration of the fire watch can be reducedto ½ hour where the PAI determines the fire hazards warrant that reduction.


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.

Hot work operations that might fall into the category where the 35 Foot Rule could be reduced include, butare not limited to, torch soldering, gas tungsten arc welding, heat gun operations, and handheld pen-typesoldering.

I would like to state that the reference to heat gun operations, and handheld pen-type soldering areinappropriate examples as justification to reduce a hot work area as it is mt belief that neither of theseoperation would require a hot work permit.

NFPA 51B, 5.4.2 Allows the 35 rule to be reduced in instances where the scope of work and tools used toconduct hot work are known to be incapable of generating slag, sparks, spatter or similar mobile sources ofignition capable of leaving the immediate area of the applied hot work. The examples used in the hot workprocedure (heat gun operations, and handheld pen-type soldering- (Electric soldering irons ie. handheldpen-type soldering irons are specifically exempted by 51B)) should be remove as neither one of theseitems would require a hot work permit to be used. As written the users at my facility have interrupted thisas if I can reduce the area when I used a heat gun or handheld pen-type soldering I must be required tohave a permit to do the work. I do not believe this meets the intent of the code.

To evaluate if a heat gun needs a hot work permit the following questions needs to be asked.

Does the heat gun produce sparks, flames or heat in a similar manner as the processes listed below? Thekey words here is similar applications. NFPA 51B was not intended to address every item that producedheat only those activities that are similar to items 1 through 7.

(1) Welding and allied processes ------No, no molten metal or slag is produced

(2) Heat treating----No, typically heat treating involves open flames at high temperatures.

(3) Grinding---------No, a heat gun does not produce hot molten sparks

(4) Thawing pipe---No, pipes are typically thawed by a torch with an open flame. A heat gun does notproduce open flames.

(5) Powder-driven fasteners-------------No, not applicable. Heat guns are not capable of being used in thismanner
