Honeywell MICRO-K 1799071 Instructions For Use page 2

INTRODUCTION
The MICRO-K is a self-contained, closed circuit, isolating breathing apparatus intended to enable
evacuation or emergency clearance of people during a forest fire where the air becomes unbreathable. This
apparatus comprises a KO2 cartridge and a breathing bag mounted on a half-face mask. The assembly is
sealed in an airtight aluminised plastic bag and stored in a portable canvass bag worn on the belt. This
system provides the wearer with an oxygen supply for more than 6 minutes.
LIMITATIONS FOR USE
The MICRO-K is only intended for evacuating firemen fighting forest fires. It is a single use device;
after use it must be discarded or reconditioned by qualified staff. The MICRO-K must only be worn by
people having undertaken practical training and appropriate practice. For this training use MICRO-K training
apparatus reference 1799002 or 1799011 (with hooks for helmet F2). To distinguish them from standard
MICRO-K apparatus, these training devices are packed in an orange bag.
The MICRO-K must only be used in the open air.
INSTRUCTIONS FOR USE
The wearer should apply the following procedure when in an unbreathable atmosphere:

Open the MICRO-K canvass bag.

If the bag contains a "PONCHO" (option), take it out and put it on.

Take out the aluminised film bag containing the MICRO-K.

Tear open the aluminised bag: a tearing guide is provided on the top of the bag.

Put the half-face mask on the face: pointed part uppermost.

Without removing the helmet, pass the elastomeric strap over the head, positioning the strap on the
nape of the neck.

If the user is not wearing a helmet, proceed in the same way and then tighten the assembly by pulling
the ends of the strap.

If the Micro-K has hooks, pass the elastomeric strap over the helmet and position it in the nape of the
neck. Insert the hooks into the appropriate parts of the helmet. Now tighten it by pulling forwards on the
ends of the strap.

Breathe in and out deeply in order to inflate the breathing bag.

Breathe normally and leave the area where breathing was impossible.

It is normal for the temperature of breathed air to increase; do not remove the apparatus
under any circumstances.

Always make sure that the respiratory protection equipment is suitable for the risks
experienced.

Any apparatus with a broken seal and/or torn aluminised film bag must be repackaged after
changing the KO2 cartridge.

KO2 extensively exposed to the air absorbs moisture from it and deteriorates into a strongly
alkaline brine. As a result, to avoid the risk of burns, an apparatus with a punctured or torn
aluminised bag must never be used.

The MICRO-K must not be used to evacuate premises, as fire-fighting equipment or an
protective equipment for men working.
