Modern airliners and aircraft that fly above 15,000 feet are required to be pressurized because the oxygen levels at such high altitudes are not sufficient for the human body's needs. If much time is spent above these altitudes without pressurization or supplemental oxygen, hypoxia can result. The symptoms of hypoxia, or a lack of oxygen in the bloodstream, include nausea, discoloration, disorientation, and severe headaches. Not all airplanes are pressurized, however. Pressurization is limited to airliners, private jets, expensive personal aircaft, and high-altitude military aircraft.
An alternative to pressurization is supplemental oxygen masks connected to oxygen tanks somewhere in the aircraft. Pilots are required to wear oxygen masks when flying above 12,500 feet for any longer than 30 minutes. At 14,000 feet, pilots are required to use supplemental oxygen at all times. At 15,000 feet, everyone on board must have supplemental oxygen.

How do airplanes protect people from decreased air pressure?
The interior of the cabin is pressurised.
Why do airplanes have pressurized Cabains?
Because the air pressure drops the higher you go. If the cabin wasn't pressurised to ground level - all the passengers (and crew) would eventually suffocate !
What is the advantage of using a pressurised nuclear reactor?
In a pressurised nuclear reactor the temperature is very high, which cn be accepted as a point for this.
Why do an aeroplane are often 'pressurised'?
As aeroplanes fly high in the atmosphere, where the air is thin, the inside has to be pressurised to allow the passengers and crew to breath.
How do people get in space?
They take it with them, in pressurised tanks.
Can you take pressurised cans onto flights?
no
Why can you wear ordinary clothes in a space shuttle?
because it has been pressurised in a similar way (outcome) to how a commercial airplane is pressurised for passengers to fly at altitude.
What is the necessity of pressurised cabins in aeroplanes?
no your gonna die
Does the temperature of nitrogen increase when it is pressurised?
Generally, yes
Experience of working in a pressurised and busy environment?
yes
What brewery was first to introduce keg beer?
Keg beer is a term for beer which is served from a pressurised keg. Watney's (UK) started with an experimental pressurised beer Red Barrel which was served in a pressurised Keg rather than the traditional Cask (barrel) in 1936. The use expanded rapidly circa 1960
Difference between hydraulics and pneumatics?
hydraulic is liquid based, pneumatic is air.
