Question 768Deck Safety70% to pass
Which of the following statements is true concerning the control activators, i.e., pull-handles, push-buttons or levers, for a space protected by a CO2 fixed fire extinguishing system?
AI Explanation
The correct answer is D) All of the above.
This is because the regulations for CO2 fire extinguishing systems require the following:
1) An alarm must sound for at least 20 seconds before CO2 is released into a space that is likely to be occupied, to allow time for evacuation (option A).
2) Two control activators are required when a stop valve is installed in the main discharge line to a space, to prevent accidental discharge (option C).
3) For discharge piping systems designed without a stop valve, only one control activator is required (option B).
Therefore, all three statements are true regarding the control activators for a space protected by a CO2 fixed fire extinguishing system.
