The ANSUL fire system uses a series of tools for fire safety. Every system has nozzles installed directly over burners, grills, ovens, and other places of high-heat, so the chemical agent can directly impact the flames the moment the temperature threshold is met. Additionally, hood vents above these nozzles help ventilate heat and smoke, further aiding in the flames suppression. Once the ANSUL system has been activated, there is also an automatic gas line shutoff feature that ensures no possibility of the fire continuing on the burner, or reigniting.
