WORKING INSIDE THE CABINET WITH BARE HANDS
Although the MUNRO cabinet can be used with long sleeved gloves it is much easier to work with bare
hands. This bare hand facility is achieved in a very simple but effective way. The Bare Hand Gauntlet
Assembly consists of four components as shown in diagram 1.
1. Sleeve 2. Solid Ring 3. Cuff 4. Bung
The inside of the sleeve is always held at positive pressure by the Gas Pressure Switch, therefore if the
Bung is removed from the Cuff, gas will flow out of the cabinet and no oxygen will enter.
To insert the hand into the cabinet simply lift up the end of the gauntlet and push the Bung into the cabinet
using the tips of the fingers only, followed by the hand
(Note: - Do not grip the end of the bung with the
fingers)
. The Cuff will seal around the wrist as shown in diagram 2. Now place the Bung inside the
cabinet in a convenient position.
To remove the hands from inside the cabinet, simply collect the Bung and release it within the sleeve.
Remove the hand and let the Bung fall into the Cuff where it will seal. Gravity will now hold the Bung in
place.
Do not attempt to pull the bung back into the cuff.
ALWAYS ALLOW THE SLEEVE TO FILL WITH GAS BEFORE INSERTING OR WITHDRAWING THE
HAND.
If the hands and Cuffs are lightly dusted with talcum powder the operation becomes very simple.
If the Cuffs are too tight around the wrists they can be trimmed to a more comfortable fit with a sharp pair
of scissors. However they must be sufficiently tight to prevent gas escaping whilst working inside the
cabinet.
Two hooks are provided just above the arm ports together with a Gauntlet Holder for use when the
Gauntlets are not being used. If the Gauntlet is fitted into the Gauntlet Holder about half way up its length,
the Holder can be clipped onto the hook. This has two effects: firstly it prevents the Gauntlets hanging
down and getting in the way and, secondly, it greatly reduces condensation in the Gauntlet Assemblies.
