Escape respirator or SCSR self-rescuer

An emergency breathing apparatus is a respiratory protective unit for emergency evacuations. Two categories exist: air purifying devices like an escape respirator which feature a filter; and air supplying devices like SCSR self-rescuers that are dedicated to emergency evacuations in confined space, poorly oxygenated or toxic environments.

Emmergency breathing apparatus are respiratory protective devices for emergency evacuations. They are regulated through the DIN 58847-7 standard for air purifying units – escape respirator – and the DIN EN 13794 standard for air supplying units – EEBDs and SCSR devices. They can only be used in this special case (emergency evacuation) and are not designed for use in on-site interventions or rescue operations.


  • Escape respirator

    An escape respirator is a respiratory protective device for emergency evacuations. These escape devices are composed by half-masks or hoods equipped with an ABEK specific filter. Like gas masks, they are effective to protect their users against organic, inorganic (except carbon monoxide) and acid substances, sulfur and ammonia compounds but offer a 15 minutes lifetime (time to evacuate).

    As they are air purifying devices, an emergency escape respirator and emergency escape hood can only be used if the oxygen rate in ambient air is above 19% volume.


  • Scsr – self-contained self-rescue device

    An SCSR - or self-contained self-rescuer - is an emergency solution safer than air purifying escape respirators. This respiratory protective equipment is a closed circuit atmosphere supplying respirator. This means that air is expired in the SCSR bag, then filtered and re-oxygenated, renewed to be breathable again.

    Because of their properties, SCSRs are perfectly suitable for confined space applications or for interventions in poorly oxygenated areas like mines. There are two categories of self-rescuer masks:

    . Chemical oxygen self-rescuer that uses a KO2 cartridge (potassium superoxide), which chemically reacts with the expired air in the bag to produce oxygen complement

    . Compressed oxygen self-rescuer which uses a small compressed oxygen cylinder to re-oxygenate expired air

    In both cases, the SCSR chemical process will trap CO2 (carbon dioxide) contained in the expired air.

Our escape respirator and SCSR range:

The EBA 6.5 uses compressed oxygen rather than chemically producing oxygen. It can be refurbed for a lower cost.

  • Self-rescuer mask EBA6.5
  • Operating autonomy / rest autonomy: 110 minutes / 8 hours
  • Less than 15 seconds to activate
  • Opening tap activation
  • Compact and lightweight: 21.6 x 30 x 11.4 cm – less than 5 kg
  • Up to 157 L of available oxygen
