Reference to Halon 1211 Hand-Hose-Line System Requirements:
NFPA 12A (Standard on Halon 1211 Fire Extinguishing Systems), Section 6.5, states that all hoses for high-pressure Halon 1211 hand-hose-line systems must be tested at 1,500 psi to ensure they can withstand operational pressure without failure.
The International Fire Code (IFC 2021), Section 904.10, also references the requirements for Halon 1211 systems, ensuring proper testing for system integrity.
Purpose of Pressure Testing:
High-pressure Halon 1211 systems operate under significant force, and hose failures could result in loss of fire suppression capability or safety hazards.
Testing at 1,500 psi ensures hoses can handle peak pressures without rupture or degradation over time.
Clarification of Incorrect Answer Choices:
A. 600 psi → Incorrect
Too low for high-pressure systems, insufficient to verify hose integrity.
B. 900 psi → Incorrect
Below the required 1,500 psi standard for high-pressure Halon 1211 hoses.
D. 2,500 psi → Incorrect
Exceeds the required test pressure per NFPA 12A; unnecessary over-testing could damage hoses.
Conclusion:
The correct and verified answer is C (1,500 psi) based on NFPA 12A and IFC 904.10, ensuring compliance with Halon 1211 high-pressure system testing standards.
