Question 1 of 205eccef9ebacbc34ba4d46482

Normally manned machinery spaces protected by a fixed carbon dioxide system fitted with storage cylinders of at least 300 pounds in extinguishing gas weight are required to be fitted with audible alarms so arranged that the alarm will be sounded prior to the discharge of CO₂. According to CG regulations pertaining to CO₂ fire protection systems, what is the minimum delay period?

🔍 Key Concepts

• 46 CFR regulations on fixed CO₂ fire-extinguishing systems in machinery spaces • Purpose of the pre-discharge alarm and time delay in normally manned spaces • The relationship between evacuation time and CO₂ release hazards to personnel

💭 Think About

• Think about why a time delay is required before CO₂ discharges in a normally manned machinery space. How long would people realistically need to recognize the alarm and escape safely? • Compare the answer choices: which ones seem too short for safe evacuation, and which might be unnecessarily long in a fire emergency? • Consider that CO₂ is dangerous to people in high concentrations. Regulations aim to balance rapid fire suppression with crew safety. Which delay best reflects that balance?

✅ Before You Answer

• Look up the specific CO₂ system requirements in 46 CFR, Subchapter F (Marine Engineering) relating to fixed gas fire-extinguishing systems in machinery spaces. • Confirm whether the regulation specifies a minimum time delay before release once the alarm has sounded (not an average or recommended time). • Verify that the delay applies to normally manned machinery spaces with CO₂ storage cylinders totaling 300 pounds or more of extinguishing agent.
