What is the fire protection capability of a Class B bulkhead?

The capability of a Class B bulkhead in terms of fire protection is indeed 30 minutes. Class B bulkheads are constructed to restrict the passage of fire and smoke for a specified period of time, which is important in maritime environments for protecting escape routes and containing the fire in its source area. The 30-minute time frame indicates that a Class B bulkhead can withstand exposure to flames from one side while preventing the fire from spreading through to the other side for at least half an hour. This rating is essential for maintaining safety during emergencies and is based on specific standardized fire resistance tests. Understanding this time frame allows maritime personnel to better assess their fire safety measures and risk management strategies on board a vessel.
