Is it possible to have a volcanic planet that is survivable by a human?

I am working on a story where ships are tricked and crash land on a volcanic planet due to some sort of electromagnetic interference. The survivors of the landing essentially become gladiators on a planet fighting for survival.

I doubt it is possible but I am curious as to whether it is possible for humans to exist relatively unaided on a volcanic planet.

• The planet does not have to have seas of lava
• It should be too hostile for extensive life (no ecosystems)
• At least 15% of the planet's surface should be liquid magma

Ideally the survivors would require as little PPE (personal protective equipment) as possible

I don't want them to have to be running around in full environmental suits and in need of oxygen tanks. Don't worry about food, water and shelter, I have that covered.

Is it possible that such a planet could have a breathable atmosphere and not be overly detrimental to exposed skin?
