🔍 Key Concepts

• Ro-Ro (Roll-on/Roll-off) vehicle spaces requirements in 46 CFR for fire protection • Differences between fire/smoke detection systems and fixed fire extinguishing systems • When the Commandant can allow alternative fire-extinguishing arrangements (like sprinkler systems)

💭 Think About

• For each statement (A, B, C), ask yourself: Does this sound like a mandatory requirement, or an optional/alternative that may be permitted? • Think about why vehicle decks on Ro-Ro vessels are considered high fire-risk areas. How would regulations typically address detection versus extinguishing in such spaces? • Consider whether regulations would normally require both detection and a particular type of extinguishing system, or if there is some flexibility.

✅ Before You Answer

• Check in 46 CFR Subchapter W (Lifesaving and Fire Protection) for Ro-Ro vehicle space fire safety requirements: Is detection required? • Verify whether an approved fixed fire extinguishing system is always required, or if an approved sprinkler system can be accepted as an alternative by the Commandant. • Before choosing "All of the above," make sure that each individual statement (A, B, and C) is independently supported by the regulation, not just "most" of them.
