Short-lived torch. I just found out from one person about a clever firefighting method that I had no idea about. He just said: “You walk in with a torch and it goes out in less than three seconds”.
This person built the first (pharmacy) high-bay warehouse in Poland, where the main method of fire protection is to keep the oxygen content in the air at a lower level. It is enough for a human to function, but nothing will burn. How much less than the usual 20.9%? It turns out that only a little less – 15% is enough to completely prevent a fire.
Perfect, especially for places where there are no or very few people (such as this highly automated warehouse, server rooms, “dark” factories, and even rarely visited archives). Sprinklers, foam installations etc. have disadvantages.
You can quickly become out of breath there, however, it is quite safe for short periods (like being at an altitude of 7000 meters). One needs to be careful with this short period because the fainting limit is for a content of oxygen equal to 16%. However, there are ways to do this. There are, of course, other interesting methods of fire protection, e.g. extinguishing with a light water mist is also quite safe for people.
And this quote with a torch described a test that checks an installation that increases the amount of nitrogen in the air, so that the oxygen was only at the level of several percent.
Has anything surprised you lately that you didn’t know?
Short-lived torch. An image from the Wagnergroup website, which specializes in such solutions. You can see that the percentage of oxygen can be slightly increased during the day if people are meant to be there. 17% of oxygen is still pretty good for fire protection.
