1 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 113-NFPA [ Global Input ] Task Group Motion: Create a global revision on gauges in Chapter 13 consolidating all other chapter references gauge and move frequencies [move to monthly and quarterly inspections]. 13.X.1.1 Gauges- Inspection. 13.X Gauges on dry and preaction systems shall be inspected weekly to visually verify that they appear to be undamaged, in good working condition, and display normal air and water supply pressure. 13.X Where supervised, gauges on dry and preaction systems shall be inspected quarterly to visually verify that they appear to be undamaged, in good working condition, and display normal air and water supply pressure. 13.X Gauges on wet and deluge systems shall be inspected quarterly to ensure that normal water pressures are being maintained. 13.X.1.2 For dry pipe or preaction systems protecting freezers with two air pressure gauges on the air line(s) between the compressor and the dry pipe or preaction valve, the air pressure gauge near the compressor shall be compared monthly to the pressure gauge above the dry pipe or preaction valve. 13.X.1.2.1* When the gauge near the compressor is reading higher than the gauge near the dry pipe valve, the air line in service shall be taken out of service, and the alternate air line opened to equalize the pressure. 13.X The air line taken out of service shall be internally inspected, shall have all ice blockage removed, and shall be reassembled for use as a future alternate air line. 13.X.1.3 Gauges- Testing. 13.X Gauges shall be replaced every 5 years or tested by comparison with a calibrated gauge. 13.X Gauges not accurate to within 3 percent of the full scale shall be recalibrated or replaced. 13.X Where multiple system risers are supplied by a common water supply source with gauges located at the same elevation, and the gauges for all systems read within 3 percent of the other(s), only one gauge shall be required to be tested to determine if replacement is required. A. 13.X Normal water supply pressure could be a pressure reading that is too high or too lowrelative to what would reasonably be expected to be found based on system design information, knowledge of the connected water supply, and/or reading data based on a series of past inspections. Normal pressure includes pressure expected to be found on a system to adequately supply the supplied fire sprinkler system. For example, a gage found reading a pressure close to or below a sprinkler system demand listed on the design placard would not be expected to be normal as, the system could have a water supply issue. Normal water supply pressure on a gage above an alarm or system check valve may be higher than that of a gauge below as a result of trapped pressure surges. This can be typical in buildings with trapped air and located close to metal deck roofs without air conditioning. Gridded systems also have a high probability of excess pressure development thus the reason, NFPA 13, Standard for the Installation of Sprinkler Systems requires relief valves on such systems.

2 National Fire Protection Association Report of /11/2015 9:51 AM Submittal Date: Sun Nov 09 07:41:35 EST 2014 Committee Statement Committee Statement: Response Message: Creating a new section dedicated to gauge inspections and testing referenced by all chapters will simplify document use and maintenance by the TC.

3 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 114-NFPA [ Global Input ] Move frequency for all tank inspections to quarterly when supervised in accordance with NFPA 72. Non-supervised systems will remain as written with weekly inspections Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Nov 09 07:50:14 EST 2014 Committee Statement Committee Statement: Response Message: This requires at least one inspection during heating season. Although not part of this standard, this revised frequency give incentive for monitoring which has a proven record. The TG recommends revising NFPA 25 to a monthly & quarterly frequency based document with single-point references where justified to minimize variation conflicts and increase general use.

4 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 115-NFPA [ Global Input ] Revise heating season reference to cold weather and add annex discussion: Annex verbiage: Cold weather is defined as temperatures that with reasonable engineering may create the potential for system damage and/or hidden performance issues. Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Nov 09 07:51:07 EST 2014 Committee Statement Committee Statement: Response Message: The references to heating season and cold weather are somewhat vague and vary geographically. Adding annex text to better describe these concepts would make the standard easier to apply and enforce.

5 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 116-NFPA [ Global Input ] Move frequency for tank water temperature inspections to quarterly. Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Nov 09 07:56:59 EST 2014 Committee Statement Committee Statement: Response Message: This is recommended as there is little justification for monthly testing. The TG recommends revising NFPA 25 to a monthly & quarterly frequency based document with single-point references where justified to minimize variation conflicts and increase general use.

6 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 117-NFPA [ Global Input ] Revise valve inspection section to read: Inspection All valves shall be inspected weekly Valves secured with locks in accordance with applicable NFPA standards shall be permitted to be inspected monthly Valves electrically supervised and compliance with in this standard shall be permitted to be inspected quarterly Control valve supervisory alarm devices shall be inspected quarterly to verify that they are free of physical damage After any alterations or repairs, an inspection shall be made by the property owner or designated representative to ensure that the system is in service and all valves are in the normal position and properly sealed, locked, or electrically supervised. Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Nov 09 07:57:46 EST 2014 Committee Statement Committee Statement: Response Message: Is there any data to support not moving to quarterly inspections from monthly? Were valves involved in impairments from NFPRF project supervised? How many impaired valves that were found were supervised? This section needs to be reviewed and further substantiated.

7 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 118-NFPA [ Global Input ] * Alarm valves and system riser check valves shall be externally inspected quarterly and shall verify the following: (1) The gauges indicate normal supply water pressure is being maintained. (2) The valve is free of physical damage. (3) All valves are in the appropriate open or closed position. (4) The retarding chamber or alarm drains are not leaking. Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Nov 09 07:59:27 EST 2014 Committee Statement Committee Statement: Response Message: Damage is a very rare event and failure is typically open. How do these get damaged- i.e. what is justification for monthly?

8 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 119-NFPA [ Global Input ] Change BFA inspection frequency to quarterly. Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Nov 09 08:01:13 EST 2014 Committee Statement Committee Statement: Response Message: IF CI 117 is converted into a Second Revision, the inspection frequency for BFAs should also be modified to correlate with that change.

9 National Fire Protection Association Report of /11/2015 9:51 AM Committee Input No. 120-NFPA [ Global Input ] Revise to read as follows: If approved locking caps or locking plugs are installed, inspections shall be annual. Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Nov 09 08:03:52 EST 2014 Committee Statement Committee Statement: Response Message: Locking type Knox caps give added protection and, only fire departments have access. The risk of theft is much less.

10 National Fire Protection Association Report 0 of 14 2/11/2015 9:51 AM Committee Input No. 124-NFPA [ Global Input ] Delete the following sections: Section (including subsections and annex) Section (including subsections and annex) Annex E (entire annex chapter) Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Sun Dec 07 16:37:09 EST 2014 Committee Statement Committee Statement: Response Message: On December 9th-10th, 2013, in Chicago, IL the NFPA Fire Protection Research Foundation conducted a workshop titled Addressing the Performance of Sprinkler Systems: NFPA 25 and Other Strategies. There was discussion that NFPA 25 should be strictly a wear and tear document. In addition, a number of attendees at the workshop stated since the main focus of NFPA 25 should be wear and tear issues, they recommended that the design evaluations and hazard analysis requirements pertaining to changes in occupancy, use or process, hazard, or the materials used or stored in a building be removed from NFPA 25 and be proposed to be relocated in NFPA 101/5000, NFPA 1, the IBC and IFC. Based on this recommendation from the subject workshop, this CI proposes to delete Sections and and all accompanying Annex material for public consideration in an effort to solicit public comments on this important subject.

11 National Fire Protection Association Report 1 of 14 2/11/2015 9:51 AM Committee Input No. 129-NFPA [ Global Input ] Revise as follows: * The property owner or designated representative shall correct or repair deficiencies or impairments that are found during the inspection, test, and maintenance required by this standard.,and that are found or observed at any time. Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address: City: State: Zip: Submittal Date: Mon Dec 08 09:02:25 EST 2014 Committee Statement Committee Statement: Response Message: The current text doesn t require that corrections or repairs be made if a problem is found or observed outside of the ITM requirements of this standard. There are many problems found or observed on systems during normal activities in a building such as a fire department walk through, or a bid review walkthrough, that should prompt notification to the building owner that corrections or repairs are needed.

12 National Fire Protection Association Report 2 of 14 2/11/2015 9:51 AM Committee Input No. 132-NFPA [ Global Input ] A Recalled products should be replaced or remedied. Remedies include entrance into a program for scheduled replacement. Such replacement or remedial product should be installed in accordance with the manufacturer s instructions and the appropriate NFPA installation standards. A recalled product is a product subject to a statute or administrative regulation specifically requiring the manufacturer, importer, distributor, wholesaler, or retailer of a product, or any combination of such entities, to recall the product, or a product voluntarily recalled by a combination of such entities. Needed corrections and repairs should be classified as an impairment, critical deficiency, or noncritical deficiency according to the effect on the fire protection system and the nature of the hazard protected. Impairments should be corrected or repaired immediately. The process of correcting or repairing an impairment should begin as soon as the impairment is discovered. Impairments are the highest priority problem found during inspection, testing, and maintenance and should be corrected as soon as possible. If the necessary parts are on hand the correction or repair can be accomplished in a matter of a few hours. However, in many cases it may take several days to order repair parts, have them shipped, and schedule manpower to make the repair. The fire protection system cannot provide an adequate response to a fire, and implementation of impairment procedures outlined in Chapter 15 is required until the impairment is corrected. Critical deficiencies need to be corrected in a timely fashion should be corrected or repaired within 30 days. The process of correcting or repairing a critical deficiency should begin as soon as it is discovered and with a sense of urgency. If the necessary parts are on hand the correction or repair can be accomplished in a matter of a few hours. However, in many cases it may take several days to order repair parts, have them shipped, and schedule manpower to make the repair. There are very few instances when a critical deficiency cannot be corrected or repaired within 30 days. If the correction or repair can t be accomplished within 30 days, the AHJ should be notified and permission obtained for an exception to this requirement. The fire protection system is still capable of performing, but its performance can be impacted and the implementation of impairment procedures might not be needed. However, special consideration must be given to the hazard in the determination of the classification. A deficiency that is critical for one hazard might be an impairment in another. Non-Critical deficiencies should be corrected or repaired within 90 days. Non-critical deficiencies do not have an effect on system performance and therefore correcting or repairing them is allowed to take longer. If the correction or repair can t be accomplished within 90 days, the AHJ should be notified and permission obtained for an exception to this requirement. Noncritical deficiencies do not affect the performance of the fire protection system but should be corrected in a reasonable time period so that the system can be properly inspected, tested, and maintained. Assembly occupancies, health care facilities, prisons, high rise buildings, other occupancies where the life safety exposure is significant, or facilities that cannot be evacuated in a timely manner require special consideration. As an example, a nonfunctioning waterflow alarm might be considered a critical deficiency in a storage warehouse but an impairment in a hospital. High hazard occupancies where early response to a fire is critical also require special consideration. A small number of painted sprinklers could be considered an impairment for a system protecting a high hazard occupancy but might be considered a critical deficiency in a metal working shop. Classifications of needed corrections and repairs are shown in Table A Submitter Information Verification Submitter Full Name: Matthew Klaus Organization: National Fire Protection Assoc Street Address:

13 National Fire Protection Association Report 3 of 14 2/11/2015 9:51 AM City: State: Zip: Submittal Date: Mon Dec 08 09:12:46 EST 2014 Committee Statement Committee Statement: Response Message: There s a need to provide some guidance for all parties involved in Inspection, testing, and maintenance on how quickly impairments, critical deficiencies, and non-critical deficiencies should be repaired. The previous text being deleted is very confusing and should not be included in NFPA 25. This subjective language should be considered if a performance based ITM program is being presented for approval
