I seem to be allergic to whatever that terrible smell is," said Gateman when the urge to sneeze had finally subsided."What terrible smell?""The air," said Gateman. "It smells...different.""That's called oxygen," said Professor Boxley. "Freh air. No cars, no buses, no factories; just pure, clean oxygen.

Freedom is the oxygen of the soul.

Faith is as essential to the spiritual realm as oxygen is to the natural realm.

For science must breathe the oxygen of freedom.

Working on the summit of Mauna Kea was comparable to working on the hospital pulmonary ward with sick people sucking on oxygen cylinders.

Oxygen deprivation and supplemental oxygen are both bio-hazards for Mauna Kea workers

He grumbles incoherently, opens the window a fraction and continues to smoke away. It__ like every time Sidney Drake enters a new location he has to readjust the atmosphere, akin to one of those sci-fi shows where they oxygenate the planet, but for my dad it__ in a suffocating reverse. He replaces the clean wholesome air with a non-stop puff of toxic poison.

I took a glass retort, capable of containing eight ounces of water, and distilled fuming spirit of nitre according to the usual method. In the beginning the acid passed over red, then it became colourless, and lastly again all red: no sooner did this happen, then I took away the receiver; and tied to the mouth of the retort a bladder emptied of air, which I had moistened in its inside with milk of lime lac calcis, (i.e. lime-water, containing more quicklime than water can dissolve) to prevent its being corroded by the acid. Then I continued the distillation, and the bladder gradually expanded. Here-upon I left every thing to cool, tied up the bladder, and took it off from the mouth of the retort._ I filled a ten-ounce glass with this air and put a small burning candle into it; when immediately the candle burnt with a large flame, of so vivid a light that it dazzled the eyes. I mixed one part of this air with three parts of air, wherein fire would not burn; and this mixture afforded air, in every respect familiar to the common sort. Since this air is absolutely necessary for the generation of fire, and makes about one-third of our common air, I shall henceforth, for shortness sake call it empyreal air, [literally fire-air] the air which is unserviceable for the fiery phenomenon, and which makes abut two-thirds of common air, I shall for the future call foul air [literally corrupted air].

When I worked on the 13,796 feet very high altitude summit of Mauna Kea we were advised to only use the medical oxygen after the daily headaches appeared and that just 15 minutes use was all that was needed to clear up the headaches for a while before we would need it again. We were not advised to use medical oxygen continuously as the Federal Aviation Regulations advises pilots to do. We were not advised to use pulse oximeters to monitor our blood oxygen levels or that the company medical oxygen should have been routinely administered only with our doctors prescription.

In Bio last year, I learned that blood is actually a dark maroon when it's inside your body. It's the exposure to oxygen that turns it bright red. And there must have been a lot of oxygen in my bathroom, because that blood was bright, bright red.

The wild gas, the fixed air is plainly broke loose: but we ought to suspend our judgments until the first effervescence is a little subsided, till the liquor is cleared, and until we see something deeper than the agitation of the troubled and frothy surface.[Alluding to Joseph Priestley's Observations on Air]

This fits in with what I saw in staff in astronomical facilities and was reporting to the management team: 10-14% Oxygen: Emotional upset, abnormal fatigue, disturbed respiration.

Astronomy staff that routinely discharged industrial gas into the indoor environment at high altitudes did not wear oxygen deficiency monitors or protective breathing respirators.

When discharging industrial gas into the indoor environment in high altitude astronomy, we never wore breathing respirators that fed us oxygenated air at above the legally required 19.5% oxygen levels.

Industrial liquid gas containers were left open and venting gas into the indoor environment in high altitude astronomy. On reflection, I realized that I routinely observed mental and physical effects that match those of a low oxygen environment in staff that I supervised.

Altitude sickness, unregulated drugs and medical gas enabled workers to become drug abusers/addicts

A healthy person that uses medical oxygen to perform their job on a daily basis should expect to eventually become a sick person.

...the life of the planet began the long, slow process of modulating and regulating the physical conditions of the planet. The oxygen in today's atmosphere is almost entirely the result of photosynthetic living, which had its start with the appearance of blue-green algae among the microorganisms.
