You know O2 is pure oxygen right? Unless we're getting into the technicality of if things in there gaseous forms can be licked it's safe.
i think gasses can be licked, for example - if i put menthol shards into hot cup of water, i can definitely feel it on my tongue if i lick the air above the cup. therefore, lickable
Get a bottle of pure oxygen and open it over a tongue-simulator¹ to see what happens.
People usually use a hot-dog. But with oxygen, even a piece of wood is close enough.
The mercury and Gemini space programs had cabins consisting of pure oxygen. And those astronauts were fine.
Apollo 1 says hi.
You need something else along with the oxygen to cause combustion.
