🔍 Key Concepts

• Fire detection requirements for cargo vessels in 46 CFR (look at parts covering cargo spaces, dangerous cargo, and vehicle spaces) • How regulations treat spaces with explosives versus spaces adjacent to explosives • Special rules for enclosed vehicle spaces that are "specially suitable for vehicles"

💭 Think About

• Ask yourself: Does the Coast Guard tend to require protection only where the dangerous cargo is, or also in surrounding/related spaces? • Think about why an enclosed space "specially suitable for vehicles" (like vehicle decks/ro‑ro spaces) might present a high fire risk even without explosives. • Consider whether the question is highlighting one specific type of high‑risk space, or whether it’s emphasizing that multiple different high‑risk spaces all need fire detection.

✅ Before You Answer

• Verify in 46 CFR what is required for spaces containing Class 1 explosives or ammunition. • Check whether adjacent compartments to explosive spaces have any explicit fire detection requirement, or if the protection is focused elsewhere (e.g., structural protection, segregation). • Look up requirements for enclosed vehicle spaces / ro‑ro spaces on cargo vessels and confirm if a fixed fire detection system is mandated there.
