Yamato Protec Gas Based Fire Extinguishing Systems Product Overview

Manufacturer: Yamato Protec Corporation
Model: Gas Based

Application

This method extinguishes fires by spraying inert gases or halogenated compounds as fire extinguishing agents, using suffocation or chemical reactions. Because it causes minimal damage after extinguishing a fire, it is widely used in computer rooms, communication facilities, and laboratories.

Gas-based fire extinguishing systems

Types of fire extinguishing gases

carbon dioxide
This method extinguishes fires by diluting the oxygen concentration in the air, causing suffocation. Because it can affect human health indoors, caution is required during installation and handling.
nitroge
This method extinguishes fires by diluting the oxygen concentration in the air, creating a suffocating effect. Because it is made from the most abundant natural substance in the air, it is non-toxic to humans and is attracting attention as a new fire extinguishing system that is kind to both people and the environment.
Halon 1301
The synergistic effect of suffocation by blocking the combustion surface and the chemical negative catalytic effect (inhibitory effect) that interrupts the chain reaction of combustion allows for extremely short extinguishing times. Installation in critical use applications is permitted.
HFC-227ea (FM-200)
Developed in the United States as an alternative to halons, this halogen-based extinguishing agent does not deplete the ozone layer.
Its fire extinguishing principle is the same as that of halons, and it is used in 95% of the world’s halon replacement systems.
If you plan to install gas fire extinguishing equipment other than Halon 1301 in a location where people are constantly present, please consult with your local fire department in advance.

The numbers in parentheses are from the IPCC Fifth Assessment Report. (The remaining atmospheric lifespan of carbon dioxide is from the IPCC First Assessment Report.)
By collecting and installing halon in a halon recycling system, we can contribute to protecting the global environment.
