Was Warrior's teak armour backing a fire hazard?

Was the teak behind HMS Warrior's armour considered a fire hazard?

The ship carried firefighting arrangements, and teak is difficult to ignite even though it burns well once a fire is established.

The answer does not deny the danger of combustible material inside an ironclad. Warrior carried firefighting arrangements intended to manage that risk. Teak takes considerable effort to ignite, although it burns readily once alight. A later exchange identifies teak and oak as the principal hardwoods builders preferred, placing the armour backing within a broader shipbuilding-material choice.
