Wood is also combustible. You need a lot of heat to make wood burn. Hold a lighter to your pencil, it will not instantly catch fire, do the same with paper and you need a water bucket nearby.
Yeah, try lighting your pencil on fire in a 100% O2 environment. It’s not the pencil being flammable that was dangerous, it was the pure oxygen atmosphere making the pencil extremely flammable to the point where a small spark from static electricity could cause it to almost instantly immolate, that made it dangerous.

Sharpen the pencil and create a bunch of tiny shavings then put them in a pure O² environment. They’ll light up real fast.
Tbe Apollo 1 fire spread so quickly because in a pure O² environment fucking velcro was super flammable.
