Snow cleaning of the world's largest telescope mirrors was an impressive sight. The optics technicians would climb into a huge telescopic boom lift and spray immense clouds of cold carbon dioxide snow and gas onto the ten meter diameter mirrors high above the floor indoors. It would cause some of the accumulated dirt to magically fall off, leaving it less dirty.

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.

Industrial gas is biologically harmful and is poorly regulated in the workplace.

Anytime that you look up to the clear sky and see colors in it, you should be suspecting that you are looking at a flow of energy through the sky that is causing a gas to glow.

Poor performing employees are the expected outcome in workers that are routinely exposed to industrial gas, chemicals, heavy metals, company supplied drugs, high altitudes, mal-acclimatization, Faraday cages, abnormal levels of radiation, industrial LASER’s, dirty electricity, social isolation, extreme night shifts, long daily commutes, and so on.

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.

During my time in high altitude astronomy, I routinely witnessed workers breathing medical oxygen, industrial carbon dioxide, nitrogen and helium gas as part of their daily work routine.

I have memories from my time in high altitude astronomy of being euphoric and giddy after discharging large amounts of industrial gas into the indoor environment. The effects would last hours and resembled being drunk and intoxicated.
