Hello Patrick,

By the information above I would say yes that the swelling and cracks have effected the integrity of the fire separation and yes you can apply OFC. If the stairway separation integrity is lost it could allow smoke and flames to penetrate the adjacent apartments via open ceiling joints.

Send me an email or call me if you want to discuss.
