🔍 Key Concepts

• Fixed CO₂ fire-extinguishing systems for machinery and cargo spaces • Regulatory requirement for a time delay and audible alarm before gas release • Purpose of CO₂ pre-discharge alarms: allow evacuation of personnel before space becomes uninhabitable

💭 Think About

• Think about how long it realistically takes a person working deep in a machinery space to recognize an alarm and reach an exit ladder or door. • Consider that the alarm must sound long enough to ensure human safety, but not so long that it seriously delays fire suppression. • Recall typical USCG/IMO training guidance on CO₂ systems: what minimum alarm time is usually emphasized in drills and classroom materials?

✅ Before You Answer

• Verify what minimum pre-discharge alarm time is specified in 46 CFR for fixed gas fire-extinguishing systems (engine rooms/cargo spaces). • Check your memory from basic firefighting and CO₂ system training—what specific number of seconds is repeatedly stressed as the minimum alarm period? • Make sure you are choosing the option that represents a minimum required time, not just a convenient or guessed time interval.
