Fire onboard a ship is among the most dangerous fire environments conceivable. Confined spaces, extreme heat and combustible materials multiply the complexity of the situation.An additional problem with fire on ships is that the location may be such that assistance from fire and rescue services is hard to get. The breathing protection available at the site has to serve different purposes; escape breathing devices are necessary for evacuation of staff members not directly involved in the fire extinguishing, and full SCBA/BA sets for the firefighters working on location.

Full composite - 6.8 L

The Interspiro ultra-light full composite cylinders comes in volume 6.8 Liter with an unlimited service life, ”NLL” — Non-Limited Life. It provides very low weight and reliable construction. The cylinder can be equipped with an optional Cylinder Quick coupling.

There are several options for the cylinder valves: 
Excess Flow Valve (EFV) = Reducing the air flow from the cylinder in case of damage or unintentional opening.
Safety ratchet = Mechanism preventing unintentional closing, "pull-to-close" or "push-to close".
Pressure gauge = Integrated small pressure gauge showing cylinder pressure.
Burst disc = A pressure relief device that protects the cylinder from overpressurization.

The following cylinder valve combinations are available.

  • In-line variant with hand wheel pointing straight down from the cylinder.
    1. Basic version
    2. EFV
    3. EFV + safety ratchet
    4. EFV + safety ratchet + pressure gauge
     
  • 90° variant with hand wheel angled 90° from the regulator connection. 
    Comes as standard with burst disc, safety ratchet and EFV.
    1. Basic version, push-to-close ratchet
    2. Pressure gauge, pull-to-close ratchet
     
  • 180° variant with hand wheel angled 180° from the regulator connection.
    Comes as standard with burst disc, push-to-close safety ratchet and EFV.
    1. Basic version
