NFPA Exam CFPE Topic 1 Question 11 Discussion

According to NFPA 101, Life Safety Code, the interior finish for exits in educational occupancies must be Class A or B. Class A finishes have the lowest flame spread and smoke development indices, while Class B finishes are also considered safe but slightly less restrictive than Class A. This requirement ensures that exit routes remain safe and clear in the event of a fire, facilitating rapid evacuation.
