Even a small increase in the oxygen level in the air to 24% can create a dangerous situation. It becomes easier to start a fire, which will then burn hotter and more fiercely than in normal air. It may be almost impossible to put the fire out. A leaking

Other than harmless water vapor (H2O), some gases are simple asphyxiants that are dangerous because they displace atmospheric oxygen (carbon dioxide, CO2; methane, CH4). There are also chemical asphyxiants (carbon monoxide, CO) that are dangerous because they prevent the oxygen that is breathed in from reaching the body’s tissues.

May be fatal at 1000 ppm in air, and its considered dangerous at 200 ppm, because it forms carboxyhemoglobin in the blood, which prevents the distribution of oxygen in the body. A safe reading on a combustible gas indicator does not ensure that CO is not present.

Atmosphere with an oxygen concentration of 19.5 percent or less is considered oxygen deficient. If the oxygen level decreases below 17 percent, people can experience disorientation, an inability to control their muscles, and irrational thinking, which can make escaping a fire much more difficult.
