Section 1 General Information
(1) FM-200® systems for spaces that are normally occupied and designed to concentrations up to the
NOAEL shall be permitted. e maximum exposure in any case shall not exceed 5 minutes.
(2) FM-200® systems for spaces that are normally occupied and designed to concentrations above
the NOAEL shall be permitted, given that means be provided to limit exposure to the design
concentrations shown in Table 1.3 that correspond to an allowable human exposure time of 5
minutes. Higher design concentrations associated with human exposure times less than 5 minutes
as shown in Table 1.3 shall not be permitted in normally occupied spaces. An exposure and egress
analysis shall be performed and approved.
(3) In spaces that are not normally occupied and protected by an FM-200® system designed to
concentrations above the lowest observable adverse eects level (LOAEL)² of 10.5%, and where
personnel could possibly be exposed, means shall be provided to limit exposure times using Table 1.3.
(4) In spaces that are not normally occupied and in the absence of the information needed to
fulll the conditions listed above, the following provisions shall apply:
(a) Where egress takes longer than 30 seconds but less than 1 minute, the FM-200® shall
not be used in a concentration exceeding its LOAEL of 10.5%.
(b) Concentrations exceeding the LOAEL are permitted provided that any personnel in
the area can escape within 30 seconds.
(c) A pre-discharge alarm and time delay shall be provided in accordance with the provisions
noted in NFPA 2001 for Time Delays.
e discharge of FM-200® into a hazard may reduce visibility for a brief period. FM-200® may cause
frostbite if liquid discharge or escaping vapor contacts the skin.
e Material Safety Data Sheet (MSDS) on FM-200® can be found in Appendix A of this manual
and should be read and understood before working with the agent. Training of personnel, re drills, and
evacuation plans should be considered.
A cylinder containing FM-200® must be handled carefully. All anti-recoil safety plugs and devices must be in
place at all times when the cylinder is not connected to discharge piping.
2
LOAEL (Lowest Observable Adverse Effect Level) - The lowest concentration at which an adverse physiological or toxicological effect has been
observed.
When FM-200® is exposed to temperatures greater than 1300°F (700°C), the potentially hazardous byproduct
hydrogen uoride (HF) will be formed. The system is designed to discharge within 10 seconds or less to minimize
the amount of HF formed during extinguishment. The effects of agent decomposition on equipment must be
considered when using FM-200® in hazards with high ambient temperatures (e.g., furnaces and ovens).
