As you go higher and higher into the atmosphere, the amount of oxygen decreases. Therefore in order to prevent altitude sickness, some people need higher amounts of oxygen via tanks to breathe.
Bit o' trivia: indigenous natives of high areas have larger lungs and improved lung functions which help them survive in such areas!
Supplemental oxygen from portable or stationary tanks

There are two different types of oxygen tanks: Liquid and Gas. Both have pros and cons, but the pro for liquid tanks is you can carry a smaller tank and have more time, but there are some safety issues. The con for gas is, if you are a person on continuous oxygen, the tanks do not last long resulting in transporting more tanks which is also a safety issue.

No. Oxygen itself is not flammable. Rather, it supports the combustion of flammable materials. Oxygen tanks do, however present a fire hazard. Normal air is 21% oxygen, while oxygen tanks carry 100% oxygen. A higher concentration of oxygen makes it easier to ignite flammable materials and allows a fire to burn hotter.
Most people bring oxygen tanks with them because of the high altitude and the thinness of the air (the oxygen at the top of Mount Everest is about 1/3 that it is at sea level). But a very few people have made it to the top without them.
Humans can no longer breathe unassisted aver 8,000 meters (26,246 feet). This is why oxygen tanks are needed on Mt. Everest.
if you mean humans then the have oxygen tanks on space suits
a camera, oxygen tanks, and other various items.
To date (end of 2017) there has been208 climbers who have climbed Mount Everest without using oxygen cylinders (tanks) and 8,098 who have used oxygen cylinders.
people are not safe in space if there air tanks run out of oxygen because there is no air in space.
Nitrous oxide tanks are BLUE
Supplemental oxygen from portable or stationary tanks
It is at sea level. The higher you climb from sea level, to reach the summit of Mount Everest (for example), the less oxygen is in the very thin air. This is why the majority of climbers of Mount Everest have to carry oxygen cylinders. Someone occasionally achieves the summit without oxygen tanks! Therefore, the higher the altitude, the thinner the oxygen in the air.
Firefighters typically get oxygen tanks from their fire department or fire station. These tanks are filled with compressed oxygen and are essential for providing breathable air to firefighters in hazardous or smoke-filled environments.
