Testing Requirements

Fire extinguishers must undergo various testing stages during manufacturing and after installation to ensure compliance with British standards. Some critical testing requirements include:

• Fire Performance Tests: These tests ensure the extinguisher can extinguish certain classes of fires effectively (e.g., a specific amount of liquid or solid material for each fire class).
• Pressure Testing: For extinguishers with pressurised cylinders (e.g., CO2), periodic pressure tests (typically every 10 years) ensure that the cylinder can handle the pressure without rupturing.
• Discharge Testing: This test ensures that the extinguisher discharges its content at a sufficient rate and volume to be effective in an emergency.

Summary of Testing Requirements:

• Monthly inspections for visible damage, proper pressure, and accessibility.
• Annual maintenance by a certified professional.
• Hydrostatic pressure testing every 10 years for high-pressure extinguishers (e.g., CO2).
• Extended discharge tests every 5 years for water, foam, and powder extinguishers.

Meeting these requirements is essential for ensuring that fire extinguishers perform effectively during emergencies and comply with UK regulations.
