SUMMARY

The discussion clarifies that oxygen is not flammable by itself; it acts as an oxidizer in combustion reactions. A fire requires three components: fuel, oxygen, and ignition energy. The percentage of oxygen in the environment influences the energy needed for ignition; higher concentrations reduce the energy required. In environments with elevated oxygen levels, such as hyperbaric chambers, even minor sparks can ignite fires, but spontaneous explosions do not occur.

PREREQUISITES
  • Understanding of the fire triangle: fuel, oxidizer, and ignition energy.
  • Knowledge of combustion chemistry and oxidation processes.
  • Familiarity with hyperbaric oxygen therapy and its applications.
  • Basic principles of gas behavior under pressure.
NEXT STEPS
  • Research the fire triangle and its implications in fire safety.
  • Learn about hyperbaric oxygen therapy and its risks.
  • Study the chemical reactions involved in combustion, focusing on oxidation.
  • Explore the historical context and safety lessons from the Apollo 1 incident.
USEFUL FOR

Students of chemistry, safety professionals, medical personnel involved in hyperbaric treatments, and anyone interested in the principles of combustion and fire safety.

And WHO has all the launch vehicles these days? The Russians got up 'there' first. US got to the Moon first - it may well be someone else for the next significant step. There's no point in crowing about a success that was more than 30 years ago. We could discuss the relative merits of spending money on Space or other things.

I seem to have made a few additions and clarifications to my post since you read it. Sorry.

As I later implied, it was war, not a foot race.

Fair enough.
I think it's so sad that the poor old Soviets actually felt so totally threatened by the West and spend so much of their meagre GDP on things like space and weapons whilst their population had such poor quality of life. That Stalin has a lot to answer for. Also Churchill and a few others.

I don't know what 'Soviets' are. People are people and leadership are those who almost invariably co-opt a piece of their action, in labor, blood, and whatever it takes to maintain their positions. I know this is far off the topic, but those who also demand you think and feel as they dictate are the most evil and labeled themselves communists. They are not communists, but frauds. By using the label of equality they promote themselves above equality for their own gain. The Russian people themselves have suffered under Czars, communists and now KGB turned mafia for a very, very, very long time. I wish them better.
