Selfrescue system KA30 & KA60

Self-rescue systems are designed to escape from a hazardous atmosphere. These devices are not designed to enter a hazardous atmosphere. The operation is quite similar of all these types of devices. Inside the device is an oxygen candle that is activated with a mechanical trigger device. After this, the user starts breathing and the initial oxygen produced by the candle triggers a process in which the CO2 produced by the user in the superoxide is converted into oxygen. The system thus has no pressure cylinder, allowing these devices to be built very compactly. The Phase KA series shown here is offered in a 30-minute and in a 60-minute version.

SR-K30 A self-rescuer oxygen device

The SR-K30 A self-contained oxygen self-rescuer is designed to protect the user’s respiratory system when withdrawing (escaping) from the zone endangered by gases harmful to health and where the concentration of oxygen is insufficient for breathing.

The device is designed for underground mining and other industries. It can be used in underground mines in non-methane and methane fields in rooms classified as “a”, “b” and “c” explosion hazard. It is used to safely leave the zone covered by fire, gas discharge or chemical installation failure. It is intended for single use only. The self-rescue device is intended only for self-rescue (escape) from the endangered zone in case of danger. The SR-K30 is not a working, rescue or diving apparatus.

KA-60 oxygen self-rescuer

The KA-60 self-rescue oxygen device is designed to protect the user’s respiratory system when withdrawing (escape) from the zone endangered by gases harmful to health and where the concentration of oxygen is insufficient for breathing. The device is designed for underground mining and other industries.

It can be used in underground mines in non-methane and methane fields in rooms classified as “a”, “b” and “c” explosion hazard. It is used to safely leave the zone covered by fire, gas discharge or chemical installation failure. It is intended for single use only. Self-rescue oxygen devices are intended only for self-rescue (escape) from the danger zone in case of danger and cannot be used during work.
