NFPA 2001 Standard on Clean Agent g Fire Extinguishing Systems Update
2
Agenda – part I • NFPA Standard Process • Changes to NFPA 2001 • New NFPA Design Concentration Effects
NFPA Standard Process • Standard out for Proposals – Anyone can make a proposal to the standard. All proposals are heard by the Technical Committee. Committee
• ROP (Report on Proposals) – After the technical proposals p a document is g generated committee meets to discuss p called the ROP. This document is voted on by the committee.
• At this time anyone can make a comment on the ROP document. document Again all comments are heard by the Technical Committee.
NFPA Standard Process • ROC (Report on Comments) – After the technical Committee meets to discuss and vote on the comments a document is generated called the ROC ROC. This document is voted on by the committee.
• At this time the document will g go before the NFPA Standards Council to become official unless a NITMAM (Notice of Intent to Make a Motion) is filed filed. NITMAM’s NITMAM s are heard at the NFPA Annual Meeting. • A NITMAM is filed when an individual does not agree with proposed change to the document. A NITMAM can be filed on a section or the whole h l d document. t
Changes to NFPA 2001 • Class A Changes – 5.4.2.4* The minimum design g concentration for a Class A surface fire hazard shall be determined by 5.4.2.4.1 or 5.4.2.4.2, whichever is greater. – 5.4.2.4.1 The extinguishing concentration, as determined in 5.4.2.2, ti times a safety f t factor f t off 1.2. 12 – 5.4.2.4.2 Equal to the minimum extinguishing concentration for heptane as determined from 5.4.2.1.
• Some S off the th Reasons R for f change h – Safety Factor of Halon 1301 and CO2 – Higher Safety Factors Used in Europe – General belief more is better
Changes to NFPA 2001 • Class C Changes – 5.4.2.5 The minimum design g concentration for a Class C hazard shall be the extinguishing concentration, as determined by 5.4.2.2, times a safety factor of 1.35. – 5.4.2.5.1 The minimum design concentration for spaces containing energized i d electrical l ti lh hazards d supplied li d att greater t th than 480 volts lt which hi h remains powered during and after agent discharge, shall be determined by testing, as necessary, and a hazard analysis.
Changes to NFPA 2001 • What NFPA 2001 was going to say regarding Class C. –
5.4.2.5.1 The requirements of 5.4.2.5 apply to the following conditions: 1. Cable bundles less than four inches (100 mm) in diameter, which include power distribution cables other than power-overEthernet (nominal 48 VDC, maximum 25 W) cables 2. Cable trays with a fill density less than sixty-percent (60%) of the tray cross-section 3 Cable trays spaced further than 10 inches (250 mm) from each other 3. 4. Individual equipment units in which the power consumption or production is less than or equal to 5 kW 5. Equipment supplied with voltage less than or equal to 480 V.
–
5.4.2.5.2 If the conditions listed in 5.4.2.5.1 are exceeded, the minimum design concentration for spaces containing energized electrical hazards which remain powered during and after agent discharge discharge, shall be determined by testing testing, as necessary necessary, and a hazard analysis.

NFPA Changes • Room Pressure Must be Determined – NFPA 2001: 5.1.2.2(10) 5 1 2 2(10) and (28) - Enclosure Pressure estimate required – Must be on plan drawings
• Why – Isolated damage to “tight enclosures” – Inert Gases and newer Liquefied agents (ECARO-25 and Novec™ 1230)
NFPA Changes g – Room Pressure • How is room pressure developed during an agent g discharge? g – Liquefied Agents – Liquid exits the nozzle and uses the room heat to help the agent vaporize into a gas. Depending on the properties of the agent more heat from the room is required. Agent

NFPA Changes g – Room Pressure • Inert Agents • Inert agents discharge as a vapor so there is no liquid vaporization. Therefore it is all positive pressure. (No negative Pressure) • A large amount of agent is discharged, therefore the pressures are generally higher than a liquid system t even though th h th the di discharge h titime iis 1 1minute.

Properties of Clean Agents • What About Inert Gas? • 1000 ft3 room at 34% is 340 ft3 of inert gas • Table from NFPA 2001
Properties of Clean Agents • Approximate final design concentration is 34% • Discharging as a vapor there is positive pressure exerted on the room • In order to keep the room in tact there must be leakage in the room. Not all leakage is room air. Inert agent also leaks out. • Equations take this into account
Properties of Clean Agents • Vapor Pressure - the pressure of a vapor in thermodynamic y equilibrium with its condensed phases in a closed system. Agent ge t

Agenda – part III • Agent Exposure Limits • Climate Issues
NFPA 2001 Agent Exposure Limits • NFPA 2001 (2008 & 2011 Edition) –1 1.5.1.2 5 1 2* Liquefied Agents …Means Means shall be provided to limit exposure to no longer than 5 minutes… – 1.5.1.3* Inert Gas Clean Agents …The maximum exposure time ti in i any case shall h ll nott exceed d5 minutes…
NFPA 2001 Agent Exposure Limits • How are exposure limits determined? • NOAEL (no observed adverse effect level) • LOAEL (lowest observed adverse effect level) – Actual test is conducted to simulate a high adrenaline level at given agent concentrations (epinephrine)
• NOAEL and LOAEL values are based on cardiac arrhythmia. • NOAEL and LOAEL values are always y lower with the use of epinephrine.
NFPA 2001 Agent Exposure Limits • What the NOAEL and LOAEL test does not do. – Does not take into account the physiological differences between test species and humans – Nothing is done to relate the cardiac sensitization eventt with ith an “i “internal” t l” measure off th the chemical h i l th thatt gets into the body during the exposure.
NFPA 2001 Agent Exposure Limits • Another way exposure limits are determined is by y PBPK ((Physiologically y g y Pharmacokinetic)) modeling Term
Definition
Physiologically
Of or relating to physiology.
Physiology
A branch of biology that deals with the functions and activities of life or li i matter living tt ((as organs, titissues or cells) and the physical and chemical phenomena involved.
Ph Pharmacokinetics ki ti
The characteristic Th h t i ti iinteractions t ti off a drug and the body in terms of its absorption, distribution, metabolism, and a de excretion. c et o
NFPA 2001 Agent Exposure Limits • PBPK is a scientific approach for determining safe human exposure limits. – Concentration and time.
• PBPK requires q that the concentration of the extinguishing agent in the bloodstream be measured. • There are differences in the absorption in test species and humans which the PBPK model takes into account account.
NFPA 2001 Agent Exposure Limits • What about Inert Agents? – With inert agents the concern is not cardiac sensitization, it is hypoxia, or oxygen deprivation.
• For more detailed information on PBPK see HARC News – March 2001, Special Edition

Update on Climate Issues • No regulations that limit or ban the use of FM200, ECARO-25, or Novec™ 1230. • HARC – Keeping up with Legislation Issues HFC s and PFC’s PFC s • HEEP Report – Emissions of HFC’s from Fire protection are estimated at less than 1% of total HFC and PFC emissions from all sources.
Update on Climate Issues • Climate change has taken a drastic change from a few years age. – Belief in Global Warming – Economy – Political Landscape
• Movement to use the Montreal Protocol to Phase Down the use of HFC’s HFC s • Phase Down but “NOT” Out – End result is in a few years there will likely be a phase down schedule for the use of HFC’s that will be supported by the producers of HFC’s
Summary • Selecting a Clean Agent – Cost – Floor Space – Room integrity – Agent Hold Time Flexibility – Container Location – Ease of Installation – Environmental Evaluation – Human Exposure
• Reason why there is more than one agent
