If cylinder pressure is low for halon or HFP, what should you do?

• A. Turn it in for repair or replacement
• B. Increase the pressure by booster
• C. Ignore the reading
• D. Replace the entire system

Answer: (A)

When a fixed fire-suppressant cylinder shows low pressure, the cylinder is undercharged or leaking and the system may not discharge reliably in an emergency. The correct action is to turn it in for repair or replacement so a qualified technician can restore proper charge or replace the unit. Boosting pressure with a booster is unsafe and not permitted for these agents, and ignoring the reading or replacing the entire system without a fault assessment isn’t appropriate. This ensures the system will function as designed when needed.
