Which of the following statements holds true for both CO₂ and Halon 1301 fixed extinguishing systems?

🔍 Key Concepts

• Fixed gas extinguishing systems design principles for CO₂ and Halon 1301 • Regulatory requirements for agent quantity/weight tolerances • Requirements for automatic shutdown of mechanical ventilation in protected spaces

💭 Think About

• Think about why ventilation must be controlled when a total-flooding gas system discharges. Would this requirement logically apply to both CO₂ and Halon 1301? • Consider whether having only one simple activation step is always acceptable from a safety standpoint, especially regarding accidental discharge into an occupied space. • Ask yourself if a 10% weight difference on a cylinder sounds like a tight safety standard for fire protection, or if regulations usually require something more precise.

✅ Before You Answer

• Verify the typical allowed weight loss percentage for both CO₂ and Halon 1301 cylinders in fixed systems. • Check whether regulations favor automatic or manual shutdown of mechanical ventilation when these systems discharge. • Consider if human safety and accidental discharge protection would permit just a single, simple action to release a large fixed gas system.

Question 1 of 27070

Which of the following statements holds true for both CO₂ and Halon 1301 fixed extinguishing systems?

A cylinder is considered satisfactory if its weight is within 10% of the stamped full weight of the charge.

If a protected space is ventilated mechanically, the ventilation system must be automatically shutdown by the release of the agent.

To avoid confusion during an emergency situation, there should be only one action necessary (such as a single pull box) to activate the system.

All of the above.
