Your second question was: "can you overdose on oxygen wearing an oxygen mask?" The answer to that is no. Oxygen masks - as used by divers, fighter pilots and sometimes hospital patients - always offer a mix of oxygen and nitrogen so that oxygen poisoning cannot occur. However, if you were to put on a mask that makes you inhale only pure oxygen, it would after a little while start to poison your central nervous system. As to 'why your friend died': I have no idea.

If your friend died after putting on an oxygen mask, it is important to consult with medical professionals to determine the cause of death. It is possible that there were underlying health conditions or complications that led to the tragic outcome. Oxygen therapy should only be administered under the guidance of healthcare providers to ensure safety and effectiveness.
The time it takes for a person to die without oxygen can vary depending on factors such as individual health, age, and the specific circumstances of oxygen deprivation. In general, a person can lose consciousness within 15 seconds and die within a few minutes if deprived of oxygen. Brain damage can occur after just a few minutes without oxygen.
Cardiac cells can start to die within 20-30 minutes when oxygen supply is cut off. Prolonged oxygen deprivation can lead to irreversible damage and cell death in the heart muscle, which can result in a heart attack. This underscores the importance of timely intervention to restore blood flow and oxygen to the heart.
Fires can die out due to lack of oxygen, fuel, or heat. Removing any of these components will extinguish the flames. Additionally, adding water or a fire suppressant can also help to put out a fire.
Actually, humans do breathe in oxygen (O2) to sustain cellular respiration, where oxygen is used to produce energy. The respiratory system takes in oxygen from the air and delivers it to the cells in the body.
Human Beings!!!! We will die without oxygen. This apples to all aninmal life.
