🔍 Key Concepts

• 46 CFR requirements for tank vessel firefighting equipment • Difference between portable, semi-portable, and fixed fire extinguishing systems • What extra protection is usually required outside machinery space entrances on tank vessels

💭 Think About

• Ask yourself: If the machinery space already has a fixed foam system, what type of backup or supplementary protection would the Coast Guard most likely require right at the entrance? • Consider what kind of equipment is normally placed near doors and access points for quick initial attack on a fire. • Think about which option would provide immediate, flexible use by crew approaching the machinery space, rather than a large built‑in system.

✅ Before You Answer

• Verify in 46 CFR that the requirement is specifically for outside the machinery space entrance on a tank vessel. • Check which of the listed options is classified as portable hand-held equipment versus part of the ship’s fixed fire main or specialized cargo-area gear. • Confirm that the selected option would be quick to deploy by one person standing at the entrance.
