c Initial Throw Range
2. Safe-Use Guidance. The toxicity guidance for the inhalation of halocarbon vapors is conservative. The development of this guidance can be found in the report referenced in appendix 3, paragraph 7m of this AC. The methodology used applies pharmacokinetic (PBPK) modeling of canine blood concentration data to perfect mixing agent decay curves. A particular PBPK model and target arterial concentration was used, as outlined in Section 4.1.2 of the aforementioned report. It assumes a compartment temperature of 70° F (21°C) at the stated pressure altitude, perfect mixing of the agent, and an agent weight of the largest extinguisher in that aircraft compartment. As a result, Halon 1211 safe-use concentrations are lower than in the previous AC. The guidance allows for adjustments for ventilation, localization and agent stratification, resulting in higher safe-use concentrations. You may elect to use safe-use W/V guidance or the minimum safe volume guidance. Both are outlined below. If used, this generally conservative guidance should protect passengers and crewmembers from neat agent toxicity, i.e. both cardiotoxicity and anesthetic effects.
a. Agent Safe-Use W/V Guidance. Consider the following:
(1) The total agent charge weight of the largest required extinguishers in a compartment divided by the compartment volume should not exceed the safe-use W/V.
A4-1
Appendix 4
(2) Multiplication factors, MF Ventilated may be applied to the safe-use W/Vs found in Figure 5 below resulting in higher safe-use agent concentrations in ventilated compartments where the air change time is known. See Figure 6 below or reference report appendix 3, paragraph 7m of this AC for the multiplication factors. These multiplication factors, referred to as the ventilation benefit in the reference report, are based on perfect mixing.

d Safe human concentrations are not available for Halon 1211. The Halon 1211 LOAEL concentration of 1.0% (v/v) has been shown to be safe for humans. See reference report in note a above. However, the safety factor is smaller than that set for the other agents.

(3) Safe-use selector curves may be used in lieu of Figure 5 and 6 above. They can be found in the reference report mentioned in paragraph 2a(2) above and can be used to obtain safe-use W/V for ventilated aircraft.
A4-2
Appendix 4
(4) Actual concentrations encountered by occupants may be significantly lower than the perfect mixing model concentrations, depending on agent stratification, air distribution, and geometry of a particular aircraft/aircraft compartment and the height and position of the occupant. A correction ultimately may be made for stratification/localization which may further increase the calculated safe-use concentration. See chapter 4, paragraph 4b(3) of this AC. The FAA will publish a report with limited examples of stratification and a methodology for use in determining this correction to adjust the safe-use concentrations for those examples. This report will include a comparison of actual post-discharge halocarbon concentration histories with perfect mixing concentration histories. The safe-use concentrations can be determined from the kinetic solution of equation 6 of the report referenced in appendix 3, paragraph 7m of this AC along with the target arterial concentrations and/or other calculation guidance provided in that report.
b. Minimum Safe Volume. This guidance may be used in place of the safe-use W/V guidance. It establishes a baseline minimum volume at which an extinguisher may safely be used, assuming perfect mixing.
The minimum safe volume is a useful tool for comparing the toxicity of hand extinguishers with the same fire fighting performance, i.e. the same U.S. - UL rating. The lower the minimum safe volume used, the comparatively less toxic the agent. Therefore, the safest extinguisher of a given rating has the lowest minimum safe volume. Obtain the minimum safe volume of an extinguisher by dividing the charge weight of the agent in the largest extinguisher in an aircraft compartment by the safe-use agent W/V for the appropriate altitude and ventilation.
Charge Weight Agent MinimumSafeVolume = Where, F is the safe-use W/V obtained from Figure 5 and 6 of this AC.
(2) Extinguishers in Unventilated Compartments. The minimum safe volume for unventilated aircraft should be used when the air change time is unknown or exceeds 6 minutes, and when multiplication factors for ventilated aircraft, MF ventilated, are not available for a particular agent. If the safe-use W/V can not be met for any of the agents, consider the relative neat agent toxicities of extinguishers in Figure 1 when selecting an extinguisher. See Figure 7 for the minimum safe volumes for extinguishers in unventilated compartments.

(3) Extinguishers in Ventilated Compartments. The minimum safe volumes of various single SB:C extinguishers when used in ventilated compartments, and assuming perfect mixing can be obtained by applying applicable multiplication factors found in Figure 6 above as a divisor to the minimum safe volume obtained in Figure 7 above.
