Semi-portable fire extinguishers used on MODUs are of the sizes __________.

🔍 Key Concepts

• MODU (Mobile Offshore Drilling Unit) fire protection requirements in 46 CFR • The difference between portable, semi-portable, and fixed fire extinguishing systems • Standard USCG fire extinguisher size classifications (I, II, III, IV, V) and which are considered larger-capacity

💭 Think About

• First, recall which extinguisher sizes are normally hand-carried by one person versus those that require a hose and/or mounting stand—how does that relate to the term semi-portable? • Think about where semi-portable units are usually installed on a MODU (e.g., machinery spaces, near high fire-load areas). Would those locations require smaller or larger capacity units? • Among the listed size groups, which combinations represent clearly larger units rather than the smallest hand-portables?

✅ Before You Answer

• Verify in 46 CFR (Subchapter I-A for MODUs) how semi-portable extinguishers are defined and what size range is specified. • Check which extinguisher sizes are normally designated for machinery spaces and flammable liquid hazards on MODUs. • Confirm which size(s) are typically classified as hand-portable only so you can rule those out from being semi-portable.
