10 of 36 2/3/ :44 AM Public Input No. 31-NFPA [ New Section after 1.1 ] 1.1.1* The AHJ is permitted to accept lesser or partial requirements of this standard. This is proposed because not all sections of this standard are intended to apply to every construction or alteration project. For example it may not be reasonable to expect a complete Fire Safety Program, including an on-site fire brigade or a pre-fire plan with the local fire department for a minor project, such as adding a light fixture. However, some sections would be applicable to all projects, such as a first aid kit (7.7.6) or good housekeeping ( ). This proposed exception allows the AHJ to make the determination on the applicability of the provisions of this standard. Note that this Public Input is related to the addition of A Related Public Inputs for This Document Related Input Public Input No. 32-NFPA [New Section after A.1.1] Relationship Submittal Date: Tue Nov 24 20:04:53 EST

11 of 36 2/3/ :44 AM Public Input No. 9-NFPA [ Section No ] A fire watch in accordance with NFPA 1 shall be posted for the duration of the work and for 2 hours thereafter for torch-applied roofing operations (see 9.3.9). This suggested revision will provide requirements for a fire watch to follow the provisions for a fire watch as set forth in NFPA 1, section Submittal Date: Mon Nov 09 21:04:18 EST

12 of 36 2/3/ :44 AM Public Input No. 10-NFPA [ Section No ] Temporary heating equipment shall be situated placed and used in such a manner so that it is secured against overturning or displacement so as to create a hazard. The new wording more directly addresses the two principal concerns of such heating equipment whether at rest or in use. Submittal Date: Mon Nov 09 21:07:38 EST

13 of 36 2/3/ :44 AM Public Input No. 11-NFPA [ Section No ] Means shall be provided to contain and dispose of leakage and spills promptly and safely. This Public Input will help ensure the spill or leak is contained first and then disposed. Submittal Date: Mon Nov 09 21:10:29 EST

14 of 36 2/3/ :44 AM Public Input No. 3-NFPA [ New Section after ] Disconnecting Means During construction or demolition activities, all temporary and permanent service equipment disconnecting means shall be readily accessible to emergency service personnel and shall be labeled as to equipment controlled by such disconnects. NFPA 70, nor the current language in NFPA 241 addresses the accessibility or labeling of service disconnecting means during construction or demolition activities. During construction or demolition activities, the ability for emergency responders to quickly identify and disconnect power to a building is critical life safety, property preservation and firefighter safety. The NFPA 70 panel has previously indicated that issues such as accessibility for FD access are beyond the scope of NFPA 70. Therefore, the issue rests with the NFPA 241 TC. Submitter Full Name: ANTHONY APFELBECK Organization: ALTAMONTE SPRINGS BUILDING/FIRE SAFETY DIVISION Submittal Date: Mon Aug 03 10:49:37 EDT

15 of 36 2/3/ :44 AM Public Input No. 2-NFPA [ Section No ] Temporary wiring and lights shall be removed immediately upon the completion of the construction or purpose for which the wiring was and lights were installed. Lighting should be included with the removal (of wiring) process to, aid in the prevention of live circuits being left behind. adding to the prevention of (possible) structural damage or personnel injury. Submitter Full Name: ROBERT TRIBBIE Organization: WEST VIRGINIA STATE FIRE MAR Submittal Date: Mon Jul 20 18:46:11 EDT

16 of 36 2/3/ :44 AM Public Input No. 34-NFPA [ Section No ] * Guard service shall be provided where required by the authority having jurisdiction. Residential buildings with combustible construction more than 40 feet above grade plane shall be provided with 24 hour, 7-day per week guard service. This proposal will address a gap in this standard that has arisen because of more permissible building codes that allow combustible construction as high as 7 stories. With the introduction of increased allowable heights and stories in building codes based on the installation of sprinklers and horizontal building separation allowances (podium construction), more and more buildings above the traditional 3 story limit for combustible construction are being built. These buildings pose a threat to adjacent properties and buildings on the same lot during construction that is not addressed in the codes or in this standard. In the past few years, a series of high profile buildings around North America have burned during construction. Many of the fires occurred after normal construction hours at unattended sites. In several of the major fires, adjacent buildings and other property have been damaged, and in almost all cases, the building under construction has been a total loss. Examples of documented fires include: Project Name / Location: Lindell Avenue Apartments, St. Louis, MO Date of Incidents: June 13, 2007 and July 18, 2012 Project Description: 4 story, 197-unit, wood framed apartment building. Building Status: Completed and occupied. This same wood framed building was also the scene of a 2007 fire that caused $12 million in damage while construction was underway. Project Name / Location: South Avalon Boulevard, Carson, California Date of Incident: October 27, 2011 Project Description: Three-story wood framed apartment building Building Status: Under construction The three-story apartment building caught fire on October 27, 2011 and quickly spread to a nearby mobile home park. More than 139 mobile homes were evacuated. At least 10 homes in the park were damaged by flames. The total damage estimate was $3.1 million, with $2.5 million for the senior living center and $600,000 for the mobile home park. Project Name / Location: Monroe Apartments, Portland, OR Date of Incident: August 8, 2013 Project Description: 46-unit, wood frame apartment building Building Status: Under construction The Monroe Apartments is one of a surge in mid-sized projects across the Portland area. Portland Fire & Rescue put the damage at $4 million. Project Name / Location: Student Apartments, Kingston, Ontario, CAN Date of Incident: December 17, 2013 Project Description: The 144-unit student wood-framed apartment complex in Kingston, Ont., was 4,559 square metres (49,072 square feet). Building Status: Under construction In all, 10 stations and 113 Kingston firefighters were on scene with 27 apparatuses; 11 Kingston fire personnel helped in communications; 11 mutual-aid departments were called and brought 160 firefighters and 19 trucks. Project Name / Location: 550 East and 500 South, Salt Lake City, UT Date of Incident: February 9, 2014 Project Description: Four story, wood frame apartment complex Building Status: Under construction The building is a four-story apartment complex. The fire caused $2.5 million in damage. 16

17 of 36 2/3/ :44 AM Project Name / Location: Mission Bay Project, San Francisco, CA Date of Incident: March 11, 2014 Project Description: The projects, supported by piles, consist of 4 and 5-story wood framed residential buildings over 2 levels of parking. The levels above the podium slabs are Type III and V. The 172 unit building was one half of the 360-unit Mission Bay Project. Building Status: Under construction The six-story, largely wood-frame building wouldn't have been permitted in California just a few years ago. Until 2008, buildings six stories or higher were required to have "noncombustible" exterior walls. Project Name / Location: Axis Apartments, Houston, TX Date of Incident: March 25, 2014 Project Description: 5 story, 396 unit wood-framed apartment building. Building Status: Under construction The inferno began as a 3-alarm fire at 12:30 p.m. but was upgraded to a 5-alarm in less than an hour. More than 400 HFD personnel responded. Project Name / Location: Gables Upper Rock, Rockville, MD Date of Incident: April 1, 2014 Project Description: The Type III 300 unit apartment complex was a five story project, with a two story cast in place parking structure and amenity deck, with three stories of apartment units built with wood framed walls, joists and roof. Building Status: Under construction More than 200 firefighters were called to the scene of a three-alarm fire. Montgomery County fire officials say the three-acre complex was 90 percent complete and expected to be finished in two to three weeks before this fire ripped through 150 units. The apartment complex is a total loss, an estimated $15-$20 million. Project Name / Location: SE Tech Center Drive/Redwood Circle, Vancouver, WA Date of Incident: June 19, 2014 Project Description: A four-story apartment building, planned to include 90 units. Building Status: Under construction. About 40 firefighters from Vancouver and Klackamas responded to the fire, which was reported around 3:15 a.m. Natural gas helped fuel the flames until a utility crew shut off the line. Estimated dollar loss falls somewhere between $2.5 million and $3.5 million. Project Name / Location: Victoria Commons, Kitchener, Ontario, CAN Date of Incident: July 22, 2014 Project Description: The Victoria Common development includes 958 units in a mixture of condominiums, townhomes and parkland. The complex is expected to be constructed in four phases over a decade. The fire was in the first phase of units and is three and four-story wood frame construction. Building Status: Under construction The fire started in the partially completed townhouse development, destroying two blocks of homes and damaging another. At least $5 million in damage was done by the blaze. Flames swept through the primarily wood frame structures in minutes before spreading. The block behind it was destroyed and partially collapsed. Project Name / Location: Apollo Way, Madison, WI Date of Incident: August 8, 2014 Project Description: The project is a four-story, 105-unit wood-frame apartment complex. Building Status: Under construction Authorities initially said the fire caused $3.5 million to $5 million in damage, but the insurer subsequently has estimated that damage is upwards of $10 million. Project Name / Location: DaVinci Apartment Complex, Los Angeles, CA Date of Incident: December 8, 2014 Project Description: The 526-unit apartment building had 1.3 million square feet of floor space, with five stories of wood framing over two stories of concrete. Building Status: Under construction The seven-story apartment building was a complete loss after fire. More than 250 firefighters were dispatched to the scene. The collapse of scaffolding and the structure s wooden frame forced the closure of northbound Harbor (110) Freeway to the northbound 101 Freeway until 10 a.m. Computers and cubicles melted in neighboring buildings. Hundreds of windows cracked. Intense heat damaged fiber-optic cables beneath a downtown freeway and melted one of the signs. There was $10 million in estimated losses and at least four nearby buildings were 17

18 of 36 2/3/ :44 AM also damaged. The Lewis Brisbois, Bisgaard & Smith building at 221 N. Figueroa St., where the computers and cubicles melted, had significant damage on its 15 floors, with 300 windows blown out. Three floors were also damaged in the Los Angeles County Department of Health Services building at 313 N. Figueroa. LA Department of Water and Power staff identified at least 160 windows, mostly on the west side of the John Ferraro Building, that were cracked. Los Angeles Department of Building and Safety reported that windows blew out in the north tower of its department headquarters, and the heat and smoke triggered sprinklers that soaked carpets and desks.

Submittal Date: Tue Dec 22 21:11:40 EST

19 0 of 36 2/3/ :44 AM Public Input No. 12-NFPA [ Section No. 7.6 ] 7.6 Standpipes. In all new buildings in which standpipes are required or where standpipes exist in buildings being altered or demolished, such standpipes shall be maintained in conformity with the progress of building construction in such a manner that they are always ready for use. For buildings under construction standpipes shall comply with section For buildings under demolition standpipes shall comply with section This addition provides a reference to provisions for standpipes. Submittal Date: Mon Nov 09 21:13:08 EST

20 1 of 36 2/3/ :44 AM Public Input No. 13-NFPA [ Section No ] At least one approved fire extinguisher also shall be provided in plain sight on each floor at each usable stairway as soon as combustible material accumulates is present. As written, the use of the word accumulates implies it is protecting against rubbish. This is intended to include all combustible construction materials that may be present. Usually construction materials aren't considered to "accumulate."

21 2 of 36 2/3/ :44 AM Public Input No. 33-NFPA [ New Section after 7.8 ] Protection of adjacent property and buildings. Residential buildings with combustible construction that is 40 feet or more in height above grade plane shall be separated a minimum of 60 feet from adjacent buildings on the same site and a minimum of 60 feet from property lines to protect adjacent property. This proposal will address a gap in this standard that has arisen because of more permissible building codes that allow combustible construction as high as 7 stories. With the introduction of increased allowable heights and stories in building codes based on the installation of sprinklers and horizontal building separation allowances (podium construction), more and more buildings above the traditional 3 story limit for combustible construction are being built. These buildings pose a threat to adjacent properties and buildings on the same lot during construction that is not addressed in the codes or in this standard. In the past few years, a series of high profile buildings around North America have burned during construction. Once built, these structures have some passive protection but it is not in place until the later phases of construction. In several of the major fires, adjacent buildings and other property have been damaged, and in almost all cases, the building under construction has been a total loss. The 60 foot distance proposed here is a minimum based on the separation distances in Table of this standard. It represents the most stringent setback from the table because this condition is similar to what exists with a building that is basically completely exposed and the framing is substantially complete before any covering materials are installed. This is the exact condition that has existed during most of the recent documented fires. Following are examples of documented fires: Project Name / Location: Lindell Avenue Apartments, St. Louis, MO Date of Incidents: June 13, 2007 and July 18, 2012 Project Description: 4 story, 197-unit, wood framed apartment building.

24 5 of 36 2/3/ :44 AM Public Input No. 14-NFPA [ Section No ] Temporary storage of equipment to be installed, combustible construction materials, or combustible packing materials shall not be permitted in unprotected structures under construction or alteration unless authorized by the authority having jurisdiction. Combustible construction materials, such as wood framing members, are usually staged on the floor under construction during construction. As currently written, this requirement makes it very difficult to follow normal framing procedures. Submittal Date: Mon Nov 09 21:18:16 EST

25 6 of 36 2/3/ :44 AM Public Input No. 15-NFPA [ Section No ] * Storage In structures required to be protected, combustible storage shall not be permitted in protected structures until until an approved level of protection is in service provided. This Public Input clarifies that combustible storage is required to be provided with protection in buildings under construction. It also requires the AHJ to approve the type and level of protection provided. The annex implies this is addressing sprinkler protection, but a standpipe system or even a fire watch may be acceptable to the AHJ. This also addresses partial protection provided by staging fire sprinklers during construction. Submittal Date: Mon Nov 09 21:21:52 EST

26 7 of 36 2/3/ :44 AM Public Input No. 16-NFPA [ Section No ] Fire doors with approved closing devices and hardware shall be installed as soon as is practicable and preferably before combustible material is introduced. The deleted language has the appearance of being both advisory and permissive. Such text should appear mandatory if it is desirable to enforce. If this text is not deleted, perhaps it should be moved to the Annex. Submittal Date: Mon Nov 09 21:24:44 EST

27 8 of 36 2/3/ :44 AM Public Input No. 17-NFPA [ Section No ] Temporary Separation Walls Protection shall be provided to separate an occupied portion of the structure from a portion of the structure undergoing alteration, construction, or demolition operations when such operations are considered as by the AHJ as having a higher level of hazard than the occupied portion of the building Walls shall have at least a 1-hour fire resistance rating Opening protectives shall have at least a 45-minute fire protection rating * Nonrated walls Walls in section and opening protectives in section shall be permitted when to be non-rated when an approved automatic sprinkler system is installed. Changing the numbering clarifies the provision and the applicability of the exception. Adding the by the AHJ gives the decision capability to the appropriate authority. Submittal Date: Mon Nov 09 21:28:12 EST

It is not necessary to include wording dealing with the opinion of the authority having jurisdiction. Such an opinion is the law and that implication is well-established through a great deal of enforcement history.

35 6 of 36 2/3/ :44 AM Public Input No. 24-NFPA [ Section No ] 10.5 * Demolition Using Explosives If explosives are used in demolition work (implosion), hose lines [at least two of 38 mm (1.5 in.) diameter or one 64 mm (2.5 in.) diameter] shall be provided in the immediate vicinity of the demolition site during the actual detonation The required hose lines shall be of sufficient length to be capable of extinguishing any small fire anywhere on the demolition site after detonation. Demolition of buildings using explosives shall be performed by qualified agency following approved procedures. This proposal is linked to a Public Input to the annex A10.5. The intent of the provisions in 10.5 and A10.5 should be switched. It seems the commentary in the annex, A10.5, is what the main provision should be requiring. And the existing provisions in 10.5 are to detailed for all demolitions using explosives and are more appropriate for the annex as guidance. This Public Input moves the intent of the annex into the body of the document with clarification and moves the intent of the existing text in 10.5 to the annex with clarification. The proposed text in 10.5 now requires a qualified agency to conduct the explosives demolition. NFPA 241 defines qualified agency as Any individual, firm, corporation, or company that, either in person or through a representative, is regularly engaged in such work, is trained and familiar with all precautions required, and has complied with all the requirements of the authority having jurisdiction. This covers qualifications and experience as implied by the existing annex. Also, the procedures are to be approved, which is defined as acceptable to the AHJ. These procedures should involve hose lines as discussed now in the proposed commentary. The verbiage from the existing 10.5 is now proposed in the annex because it is more like commentary. Each demolition site is unique and the type of fire protection measures cannot be specified in the text. It is clear that some sites may need more hose lines than are currently required in the text of the document. As such, this language is relocated to the annex as guidance.

41 2 of 36 2/3/ :44 AM Public Input No. 27-NFPA [ Section No. A.10.7 ] A Vertical open shafts in buildings under demolition have been a major factor in the rapid spread of fire throughout such buildings. Outside shutes should be used where possible so that floor-to-floor integrity can be maintained. A When a building is being demolished in stages, the walls and shafts that assist in preventing the spread of fire should be left remaining as long as possible. In situations where adjacent structures are to remain standing, demolition should be started immediately adjacent to the structures to be left standing, thereby creating a space separation between the structures that will remain through the balance of the demolition work.
