What happens if the percentage of oxygen in the air reaches to 70%?

If the percentage of oxygen in the air reaches 70%, then any substance that catches fire will become difficult to extinguish the fire, as oxygen supports combustion.

Extra information: The Earth's atmosphere is made up of a mixture of gases called air. These are colourless and odourless gases. It is made up of 78 % nitrogen, 21% oxygen, and 1 % other gases and water vapour. It also contains trace amounts of carbon dioxide, neon, helium, methane, krypton, hydrogen, nitrous oxide, xenon, ozone, iodine, carbon monoxide, water vapours, and ammonia.

Oxygen: Oxygen accounts for 21% of the atmosphere. It is extremely reactive and forms compounds with a wide range of other chemicals, and it is required for living creatures to breathe. All living things (except anaerobic organisms) need oxygen to survive. Oxygen helps organisms grow, reproduce, and turn food into energy. Humans and animals get the oxygen they need by breathing through their nose and mouth into their lungs. The oxygen present in the air assists in burning. Oxygen is necessary for burning substances. Oxygen is essential for respiration as the body uses it to 'burn' food molecules.]
