Product description
STSM 5000 Hyperbaric Foam Fire Extinguisher
The STSM 5000 is a refillable hyperbaric foam fire extinguisher designed for use on Class A and B fires. It contains a non-toxic aqueous foam extinguishant and supports both intermittent and continuous discharge. The extinguisher must not be used on electrical fires over 24 volts.
Designed for hyperbaric conditions, the STSM 5000 has a maximum working depth of 450 metres. It operates within a temperature range of 2°C to 50°C. The cylinder has a total volume of 7 litres and contains 5 litres of extinguishant. Its maximum working pressure is 100 bar.
The extinguisher uses helium, nitrogen or bottom mix as propellant gas, provided that the gas is compatible with the chamber atmosphere.
Pre-Dive Checks
Before each operation, check the extinguisher carefully. The charge pressure should be between 70 and 100 bar. For dives deeper than 200 metres, the charge pressure must be between 95 and 100 bar.
Check that the safety pin is correctly in place. Also inspect the extinguisher for any signs of leakage, corrosion or mechanical damage before use. These checks help confirm the condition of the extinguisher before entering the hyperbaric environment.
Operation
The STSM 5000 uses a straightforward operating procedure. First, remove the safety pin. Aim the nozzle at the base of the fire and squeeze the trigger to activate the extinguisher. The system allows both intermittent and continuous discharge, depending on how the extinguisher is operated.
The extinguisher is supplied with a hose and bracket, providing the components required with the unit.
Maintenance and Recharging
The STSM 5000 is refillable, allowing the extinguisher to be recharged after use. Maintenance and recharging information is provided on the label on the reverse side of the cylinder.
With its 5-litre extinguishant capacity, 450-metre maximum working depth and hyperbaric-compatible propellant gas options, the STSM 5000 provides a foam extinguishing solution specifically intended for Class A and B fires in hyperbaric conditions.
