Question 1 of 27070

The space containing carbon dioxide cylinders shall be properly ventilated and designed to prevent an ambient temperature in excess of __________.

🔍 Key Concepts

• Fixed CO₂ fire-extinguishing systems on vessels and their installation requirements • Effect of high ambient temperature on gas cylinder pressure and system safety • Relevant requirements in 46 CFR for CO₂ cylinder storage spaces

💭 Think About

• Think about what happens to the pressure inside a CO₂ cylinder as the surrounding temperature rises. At what point could this become a safety concern? • Which of these temperatures seems like a realistic upper design limit for a machinery or cylinder room on a steel vessel in a warm climate, without risking cylinder overpressure? • Compare the choices: which are more like normal comfort temperatures, and which are more like equipment or safety limit temperatures?

✅ Before You Answer

• Verify in 46 CFR requirements for fixed CO₂ systems what maximum ambient temperature is specified for the cylinder storage space. • Check which temperatures listed would be routinely exceeded in hot machinery spaces or deck areas, and which would be considered a design cap. • Confirm that the chosen temperature makes sense to prevent excessive cylinder pressure but is still practical for shipboard conditions.
