    (2) When should a person don the M-20.2 EEBD? The EEBD should be put on at the first indication of fire, explosion or suspected oxygen deficiency, when you feel faint or a person near you faints.

  • Page 14: Effects Of Oxygen Deficiency

    5.1. Effects of Oxygen Deficiency Oxygen is odorless, colorless and tasteless, so it’s presence or absence is impossible to detect with the senses. However, when the air you breathe is deficient in oxygen, some of the physiological effects you may experience can give you clues that you are in an oxygen deficient atmosphere. People breathing air that has as little as 13% to 17% oxygen usually become dizzy, notice buzzing in their ears, can have a rapid heart rate, and often suffer headaches.
