Oxygen deprivation and supplemental oxygen are both bio-hazards for Mauna Kea workers
In high altitude astronomical facilities we routinely discharged large amounts of nitrogen gas into closed spaces. We were never informed by the astronomy management team about the abnormally low oxyg...
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...
At the W.M. Keck Observatory on the very high altitude summit of Mauna Kea, there was no routine monitoring of mental functioning, blood oxygen levels, blood pressure or heart rate of workers.
When the National Optical Astronomy Observatory (NOAO) found out that Occupational Safety and Health Administration (OSHA) were going to visit the site to assist in bringing it into legal compliance,...
When I worked in high altitude astronomy, the worst sickness that I experienced was not at the 13,796 feet very high altitude summit of Mauna Kea Observatory (MKO) in Hawaii, it was at Kitt Peak Natio...
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...
My memories of my time in high altitude astronomy indicate that there were no oxygen concentration monitors or alarms in the areas that liquid nitrogen was in use at the high altitude astronomical fac...
I have been through the OSHA system twice and I can confirm that I did not have the right to a safe workplace or whistle-blower protection on either occasion.
Abnormal radiation exposure and oxygen starvation teaches you that reality is just a perception that is derived from your immediate environmental conditions.
