Date: July 1, 2014

Subject: NFPA 418 First Draft TC FINAL Ballot Results (F2015 Cycle)

According to the final ballot results, all ballot items received the necessary affirmative votes to pass ballot.

14 Members Eligible to Vote

6 Not Returned (Aaron, Gammon, Kaisler, Buehler, Kays, Smith)

8 Affirmative on All Revisions (Syms, with comment on one or more Revisions)

0 Negatives

0 Abstentions

The attached report shows the number of affirmative, negative, and abstaining votes as well as the explanation of

the vote for each first revision, if applicable.

There are two criteria necessary for each first revision to pass ballot: (1) simple majority and (2) affirmative 2/3

vote. The mock examples below show how the calculations are determined.

(1) Example for Simple Majority: Assuming there are 20 vote eligible committee members, 11 affirmative votes

are required to pass ballot. (Sample calculation: 20 members eligible to vote ÷ 2 = 10 + 1 = 11)

(2) Example for Affirmative 2/3: Assuming there are 20 vote eligible committee members and 1 member did not

return their ballot and 2 members abstained, the number of affirmative votes required would be 12. (Sample

calculation: 20 members eligble to vote – 1 not returned – 2 abstentions = 17 x 0.66 = 11.22 = 12 )

As always please feel free to contact me if you have any questions.

Committee Statement




Sections 5.7, 5.8, 5.9, and 5.10 were reorganized and combined into a single 5.7 to provide clarity.

5.7.1.4 (previous 5.7.6): Update reference.

5.7.2.1 (new): The standard should identify an appropriate installation standard for fixed foam systems.

5.7.2.3 (previous 5.7.3.2): The foam discharge duration was revised to be consistent with NFPA 16 and NFPA 409. There are operational and first-responder issues that would benefit from the increased duration. Rooftop heliports are not easily accessible to first-responders within a five-minute time frame.

previous 5.7.3.2.1 (deleted): Chapter 6 of NFPA 409 no longer provides guidance on the supply calculation method.

5.7.2.6.2 (previous 5.8.2): Combined into a single sentence to meet the Manual of Style.

5.7.2.6.3 (new): It is important that personnel on the rooftop are able to locate and identify the correct activation station during an emergency.

5.7.2.6.4 (new): The new text provides additional guidance on the location of the foam system shutoff.

previous 5.7.4.3 (deleted): Chapter 6 of NFPA 409 no longer provides guidance on the supply calculation method.

5.7.6.1 (previous 5.7.7: The intent is to provide sufficient foam concentrate for the largest system, based on the supply calculation method. Multiple pads may be covered by a single system or individual systems. The previous terminology, which tied the requirement to "pads", did not accomplish this intent.

5.7.9 (new): Foam systems installed in accordance with NFPA 11 are not covered by NFPA 25.

Affirmative with CommentSyms, Raymond A. 5.7.2.6.5 An approved manual control for foam system shutdown shall be accessible at all times, including the time of fire and system operation. COMMENTS: This needs to beexpanded with requirements for the shutoff being co-located with activation controls. A quick shutoff is needed in the event of an inadvertent discharge, need for rescue persons to reach the helicopter, fire under control to preserve foam or at end of foam duration to shut off foam to prevent the foam blanket from being washed away by the water only discharge. This currently allows for the shutoff to be isolated from the heliport attendant as long as it is accessible which needs to be spelled out.

5.8.2 5.7.2.6.2* The activation shall be by manual pull stations located at each egress point from the rooftop landing pad. An additional manual pull station Manual actuation stations shall be located at each egress point from the rooftop landing pad and at an approved location inside the building from which the rooftop landing pad can be viewed.

SUBSTANTIATION for 5.7.2.6.2: Combined into a single sentence to meet the Manual of Style.

A.5.8.2 A.5.7.2.6.2 It is acceptable for the rooftop landing pad to be viewed using video or other acceptable means.

5.7.2.6.3 Manual foam activation stations shall be clearly labeled or identified as to the purpose and hazard protected.

SUBSTANTIATION for 5.7.2.6.3: It is important that personnel on the rooftop are able to locate and identify the correct activation station during an emergency.

SUBSTANTIATION for 5.7.2.6.4: The new text provides additional guidance on the location of the foam system shutoff.

5.7.4 5.7.3 Manual Fire-Fighting Equipment. 5.7.4.1 5.7.3.1* The area of application of foam discharge for hose line systems shall be the practical critical fire area for the category of the helicopter landing facility in accordance with Table 5.7.4.1 5.7.3.1. Table 5.7.4.1 5.7.3.1 Practical Critical Fire Areas for Hose Line Systems Only

A.5.7.4.1 A.5.7.3.1 The area of application and the duration where using a hose line system is reduced because foam is applied efficiently and directly on the fire by trained personnel.

5.7.4.2 5.7.3.2 The duration of foam discharge for the hose line systems shall be 2 minutes. 5.7.4.3 The supply calculation method shall be performed in accordance with Chapter 6 of NFPA 409, Standard on Aircraft Hangars.

SUBSTANTIATION for old 5.7.4.3: Chapter 6 of NFPA 409 no longer provides guidance on the supply calculation method.

5.7.5.2 5.7.4 Supplementary Protection. Standpipes and hose stations, if used, shall be installed in accordance with NFPA 14, Standard for the Installation of Standpipe and Hose Systems. 5.7.5 Water Supply. 5.7.5.1 The water supply for the foam system shall be from a source approved by the AHJ. 5.7.5.1 5.7.5.2 Fire pumps, if used, shall be installed in accordance with NFPA 20, Standard for the Installation of Stationary Pumps for Fire Protection. 5.7.6 Foam Concentrate Supply.

5.7.7 5.7.6.1 At facilities where there is more than one rooftop landing pad, the The supply of foam available concentrate shall be sufficient to cover an incident on at least one of the pads supply the largest system.

SUBSTANTIATION for 5.7.6.1: The intent is to provide sufficient foam concentrate for the largest system, based on the supply calculation method. Multiple pads may be covered by a single system or individual systems. The previous terminology, which tied the requirement to "pads", did not accomplish this intent.

5.7.9 5.7.6.2 The foam concentrate for the fixed system or manual firefighting equipment shall be listed in accordance with UL 162, Standard for Foam Equipment and Liquid Concentrates, and shall be on the qualified products list for MIL-F-24385, or equivalent. 5.9 5.7.7 Fire Alarm. 5.7.7.1 A means of communication shall be provided from the roof area to notify the fire department of emergencies. 5.9.1 5.7.7.2 Where buildings are provided with a fire alarm system, a manual pull station shall be provided for each designated means of egress from the roof.
