When I saw how many people were objecting to the construction of the Thirty Meter Telescope atop Mauna Kea, I realized that there needed to be an open and honest discussion about the toxicity of the 13,796 feet very high altitude summit and the health and safety issues of astronomical observatories.

During my five years on Mauna Kea, workers routinely displayed the symptoms of Cerebral Hypoxia.

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.

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.

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.

An open flask of industrial liquid gas that is venting into the indoor environment should be thought of as the same as a smoldering fire, as they both create a dangerous oxygen deficient environment for the human.

You know when 1 in 2 marriages ends in divorce, 1 in 42 boys have Autism, and safety complaints from the majority of whistle-blower's are not being upheld, that you are living in a seriously dysfunctional society.

OSHA's lack of law enforcement has made the USA a dangerous place to work.

The USA has a long history of radiation damaging workers health.

I advise people to avoid workplaces that prevent Occupational Safety & Health Administration (OSHA) visits.
