1.1.1*

The AHJ is permitted to accept lesser or partial requirements of this standard.

Statement of Problem and Substantiation for Public Input

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 (7.1.2-1). 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.1.1.1.

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.

7.2.5.1*

Guard service shall be provided where required by the authority having jurisdiction. Residential buildingswith combustible construction more than 40 feet above grade plane shall be provided with 24 hour, 7-dayper 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: Mission Bay Project, San Francisco, CADate of Incident: March 11, 2014Project 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 constructionThe 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, 2014Project Description: 5 story, 396 unit wood-framed apartment building.Building Status: Under constructionThe 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, MDDate of Incident: April 1, 2014Project 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 constructionMore 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, WADate of Incident: June 19, 2014Project 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, CANDate of Incident: July 22, 2014Project 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, WIDate of Incident: August 8, 2014Project 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, CADate of Incident: December 8, 2014Project 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

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.

Public Input No. 33-NFPA 241-2015 [ 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 shallbe separated a minimum of 60 feet from adjacent buildings on the same site and a minimum of 60 feet fromproperty 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 4.2.1 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:

9.5.5

Where in the opinion of the authority having jurisdiction there is danger of physical damage to the fuelcontainers, protection shall be provided Fuel containers shall be protected against physical damage asapproved .


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. The wording, if left unchanged, will be open to unnecessary speculation and potential litigation. This requires protection from physical damage and that it be approved, which is defined as "approved by the AHJ."

Public Input No. 24-NFPA 241-2015 [ Section No. 10.5 ]

10.5 * Demolition Using Explosives.

10.5.1

If explosives are used in demolition work (implosion), hose lines [at least two of 38 mm (1.5 in.) diameter orone 64 mm (2.5 in.) diameter] shall be provided in the immediate vicinity of the demolition site during theactual detonation.

10.5.2

The required hose lines shall be of sufficient length to be capable of extinguishing any small fire anywhereon 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.

Public Input No. 26-NFPA 241-2015 [ New Section after 10.7.2 ]

10.7.3

Demolition shall begin immediately adjacent to structure to be left standing.


This Public Input is related to a Public Input to the annex. The first sentence in the annex addresses demolition of buildings adjacent to buildings that will remain. There is no provision in the text of section 10.7 that addresses this subject. So, 10.7.3 is added to relate to the first sentence in the annex, which is proposed to become A.10.7.3. The remaining text in the annex is revised to further explain the provision of 10.7.1 and this annex material is identified as A.10.7.1.

10.8.5 * Fire Extinguishing Equipment Protection .

Fire extinguishing equipment Approved fire protection shall be available subject to the authority havingjurisdiction provided .


This Public Input is related to Public Inputs to the annex. As indicated in Public Input to A.10.7, hose lines should be available on site. The number and position of hose lines should be determined by the AHJ. The required hose lines shall be of sufficient length and number to be capable of extinguishing any small fire anywhere on the demolition site after detonation. This suggested revision clarifies that fire protection is required as approved. The term "approved" is defined to be as by the AHJ. Fire protection is a more general term that could include a fire watch, or other means. The revisions to the annex clarify that hose lines supplied by hydrants or riser adapters are preferred.

A.1.1.1

Not all sections of this standard are intended to apply to every construction or alteration project. Forexample it may not be reasonable to expect a complete Fire Safety Program, including an on-site firebrigade 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 goodhousekeeping (7.1.2-1). This proposed exception allows the AHJ to make the determination on theapplicability of the provisions of this standard.

A.10.7 .1

Vertical open shafts in buildings under demolition have been a major factor in the rapid spread of firethroughout such buildings. Outside shutes should be used where possible so that floor-to-floor integritycan be maintained.

A.10.7.3 When a building is being demolished in stages, the walls and shafts that assist in preventing thespread of fire should be left remaining as long as possible. In situations where adjacent structures are toremain 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 thedemolition work.
