🔍 Key Concepts

• Fixed fire-extinguishing systems commonly used in machinery spaces on large commercial vessels • Properties and typical applications of CO2, Halon, dry chemical, and foam systems • Environmental and regulatory restrictions on certain gaseous agents for new installations

💭 Think About

• For a large modern diesel-electric AC propulsion generator, is the space more like an electrical/machinery enclosure or a fuel spill/foam deck area? • Which of these agents can safely and effectively flood an enclosed machinery space without leaving residue that could damage electrical equipment? • Which agents have been largely restricted or phased out for new installations due to environmental regulations?

✅ Before You Answer

• Verify which extinguishing agents are typically used in fixed flooding systems for machinery/electrical spaces on ships • Check which option would be clean, non-conductive, and non-residue-forming, suitable for generators and switchboards • Eliminate choices that are mainly used for local fuel spill or deck fires rather than total-coverage machinery space protection
