Is heptafluoropropane harmful to humans?
People often ask, is heptafluoropropane harmful to the human body? Does the use of heptafluoropropane require an evacuation of the protected area? Heptafluoropropane reaction concentration is 9%, no obvious damage, no adverse reactions; toxic reaction concentration is 10.5%. The design concentration of heptafluoropropane is generally less than 10%, which is safe for human body, so it can be used to protect places with many people. However, some manufacturers do not design according to the specifications. Therefore, when purchasing heptafluoropropane fire extinguishing, it is necessary to strictly check whether the concentration of the fire extinguishing agent exceeds the standard to ensure the safety performance of the equipment. The combustion of the fire site may produce harmful gases, so not only the toxicity of the product itself, but also the internal conditions of the protection zone. Therefore, before the heptafluoropropane fire extinguishing agent is sprayed, it should be ensured that all personnel have been evacuated to ensure the safety of personnel.
