The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or hypo-baric or submerged chambers, etc.).
A global helium shortage has doctors worried about one of the natural gas’s most essential, and perhaps unexpected, uses: MRIs.. Strange as it sounds, the lighter-than-air element that gives ...
Helium also has a very low boiling point (-268.9°C or -452°F), allowing it to remain a gas even in super-cold environments, an important feature because many rocket fuels are stored in that ...
The world is running out of helium. Helium is the only element cold enough to keep MRI machines cool enough to function. Without it, doctors lose a valuable imaging tool.
While asphyxiation by helium can be detected at autopsy, there is currently no test that can detect asphyxiation by nitrogen. For this reason, nitrogen is commonly the preferred choice for people who do not want the cause of death established. [4] [5] [6] Suicide bags were first used during the 1990s. The method was mainly developed in North ...
The risk of breathing asphyxiant gases is frequently underestimated leading to fatalities, typically from breathing helium in domestic circumstances and nitrogen in industrial environments. [12] The term asphyxiation is often mistakenly associated with the strong desire to breathe that occurs if breathing is prevented.
“We have some issues to watch overnight when in regards to the helium leaks that was just brought up, and we have a lot of smart people down here on the ground that are going to take a look at ...
