Curt F. is probably correct in his estimate that heptafluoropropane extinguishes fire primarily by physical means. According to an overview by Choy and Fong, ''An Introduction to Clean Agents: Heptafluoropropane'' (Int. J. on Eng. Performance-Based Fire Codes, vol. 5, nr 4, p. 181 $-$ 184, $2003$),. For heptafluoropropane, the contribution of physical mechanisms to the
An FM 200 fire suppression system is a clean agent fire suppression solution that uses a colorless, odorless gas called FM-200 (heptafluoropropane) to extinguish fires. Unlike water-based systems, FM 200 systems are designed to quickly suppress fires without causing damage to sensitive equipment or leaving any residue.

To investigate the efficiency of heptafluoropropane fire extinguishing agent on suppressing the lithium titanate battery fire, an experimental system was designed and built to perform the extinguishing test. The lithium titanate battery (50 Ah, 2.3 V) with diameter of 66 mm and length of 260 mm was used.
The battery temperatures, ignition time, release time of the agent, time to extinguish the fire, battery mass loss, amount of used agent and mean discharge rate of agent were obtained and analysed.

However, Halon agents have severe damage to the ozone layer and are difficult to degrade. As the substitute of Halon, heptafluoropropane fire extinguishing agent (HFC-227ea) is more environmentally friendly, less toxic and shorter lifetime in atmospheric, and most importantly, it is electrically insulating.
The addition of 2% PMMA@DMTP and UF@PMP microcapsules reduced the MEC of N 2 by 24.2% and 26.3%, suggesting that incorporating microcapsules into the fuel could diminish the amount of fire-extinguishing agents needed. However, the effects varied with different microcapsules.
The thermal-response mechanism of microcapsules constitutes a comprehensive mechanism with physical and chemical effects. The finding of this research offer a new technical approach for microencapsulating high-boiling-point gas extinguishing agents, facilitating intelligent and precise prevention of early fires resulting from combustible materials.
Physical cooling and blocking the chemical reaction of combustion are the main principles for HFC-227ea to extinguish battery fire. The fire was put down within a very short period of time in all the four tests, which indicates that the HFC-227ea can be used to suppress the LTO battery fires.
