2.1 INTRODUCTION

2.1.1 The Hy-Fex Hyperbaric Fire Extinguisher comprises;

• Aluminium Cylinder• Trigger Valve Assembly including pressure gauge and burst disc• Outlet Hose & Nozzle• Foam Mixture & Gas Propellant

2.1.2 The fire extinguishing medium is an aqueous film forming foam (AFFF) concentrate mixedwith water and propelled by pressurised air or heliox.

2.1.3 The volume of the foam/water mixture is 75% of the cylinder volume, the remainder beingpressurised gas.

2.1.4 The working pressure of the extinguisher is 133 Bar, and is operable at depths down to450msw.

2.1.5 The Hy-Fex fire extinguisher is ideally suited for hyperbaric environments due to;

a. Propellant operating pressure substantially higher than conventional fire extinguishers,with a charge pressure differential of up to 88 bar for a maximum operating depth of450 MSW, thus providing excellent energy potential to propel the extinguishing agentrapidly and effectively.

b. A wide operating temperature range from -15°C to +55°C. Ambient temperaturesbelow freezing may reduce foam expansion from the standard 10:1 ratio to anapproximate 9:1 ratio.

c. An optimised flow restriction incorporated into the trigger valve assembly ensuresrelatively constant discharge rates at all depths.

d. A consistent foam texture at all depths improves extinguishing effectivity. Foam texturegenerally improves as ambient pressure (gas density) increases. At shallower depthshigher pressure differentials between the propellant and ambient pressure, with the aidof the venturi nozzle, ensures a consistent foam texture is maintained.

e. Suitable for fabrics, combustible solids, flammable liquids and electrical fires up to 24Volt.

2.2 SERVICING AND RECHARGING INSTRUCTIONS

WARNINGUsers should ensure that the charging facility has an appropriate pressurelimiting or warning device to avoid over pressurising the extinguisher.

5.2 CYLINDER INSPECTION

Cylinders must be visually inspected internally every 6 months by a competent person.

Discharge the extinguisher and remove the valve to allow internal inspection of the cylinder.

EN 1802 ‘Periodic inspection and testing of seamless aluminium alloy gas cylinders’provides the following guidance on cylinder inspection:

Inspect each cylinder internally using illumination to identify any defects such as dents, cuts,cracks, lamination or corrosion (See EN 1802 6.2a & 6.2c). Ensure the method ofillumination presents no hazard to the tester. Remove any internal liner or coating thatobstructs visual inspection (Note: Divex cylinders are not normally lined or coated).

Any cylinder showing presence of foreign matter or signs of more than light surface corrosionshould be cleaned internally under closely controlled conditions by shot blasting, water jetabrasive cleaning, flailing, steam jet, hot water jet, rumbling chemical cleaning or othersuitable method. Refer to EN 1802 annex E for further information on cleaning methodswhich must be compatible with the cylinder material.

If cleaning is required the cylinder should be re-inspected after the cleaning operation.

Where there is doubt concerning the type and/or severity of a defect found during visualinspection additional tests or methods should be conducted such as ultrasonic techniques,check weighing or other non-destructive tests. Only when all doubts are eliminated may thecylinder be further processed (Refer to Annex C of EN 1802 for detailed guidance on defectevaluation)

Weekly • Check pressure is at 133 Bar.

• Check safety pin is in position and sealed.

• Check cylinder for external damage.

• Examine hose / nozzle assembly.

Six Monthly • Discharge contents and carry out internal visual inspection.*

Five Yearly • Perform hydrostatic expansion test in accordance with BS EN 1802:2002, or IMCA D018, or in accordance with an equivalent recognised standard.*


5.3 HYDROSTATIC EXPANSION TEST

A hydrostatic expansion test shall be conducted at a period specified by national regulationsand in accordance with those regulations by a competent body. Where no nationalregulations exist attention is drawn to IMCA document D018.

5.4 MISUSE AND MISHANDLING

The fire extinguisher and cylinder must never be misused and / or mishandled. Misuse ormishandling may result in injury or death and damage to property. Always stow, store,charge, operate, maintain, inspect and test in accordance with this manual.
