According to NFPA 1403, what is the recommended instructor-to-student ratio?

According to NFPA 1403, the recommended instructor-to-student ratio is 1:5. This ratio ensures that each instructor can provide adequate attention and supervision to each student, facilitating effective learning and safety during training exercises, particularly in live fire scenarios. A lower ratio allows instructors to interact more personally with students, addressing individual needs and ensuring that safety protocols are thoroughly understood and followed. The recommended 1:5 ratio aids in maintaining a controlled learning environment where students can receive proper guidance and support, which is crucial for both skills development and safety in fire training.
