đ Key Concepts
⢠46 CFR Subchapter W requirements for fire protection in galleys
⢠How portable extinguisher size ratings (B-I, B-II, B-V / 10-B:C, 40-B:C, 160-B) relate to the size of the hazard area
⢠The special fire risks in a galley (cooking oils, grease, electrical equipment) compared with a normal accommodation space
đ Think About
⢠First, think about whether a 2,900 sq ft galley is considered a small, medium, or very large hazard area under the portable extinguisher tables in the regulations.
⢠Compare how much protection each extinguisher size (B-I vs B-II vs B-V or their modern B:C equivalents) provides; which rating sounds appropriate for almost 3,000 sq ft of cooking space?
⢠Ask yourself: would regulations typically require just the minimum size extinguisher for that area, or a significantly larger extinguisher class when the space includes highârisk cooking operations?

Before You Answer
⢠Look up the CFR table for minimum number and size of Bâtype extinguishers required for machinery and galley spaces by square footage.
⢠Confirm which extinguisher sizes are considered equivalent before and after 2017 (BâI â 10âB:C, BâII â 40âB:C, BâV â 160âB).
⢠Verify whether a single small extinguisher can legally cover 2,900 sq ft of galley or whether the table requires a larger rated unit or multiple units.
