Danger of uncontrolled electrical discharge
►
Always clean the door with a moist, lint free
cloth.
►
Do not use a dry cloth.
Maintaining statically charged door
In certain circumstances, the door can become statically charged.
One possible cause of this is when two non-conducting substances e.g. CTU
gloves (neoprene), see-through door (Makrolon), cleaning cloths (cellulose or
cotton), are rubbed against one another, thus causing static charge to build
up. Discharging may be slowed down by the ambient conditions, such as dry
air and low external temperatures.
One visual feature which comes about when using the "G 60 Spezial" test
liquid is that a film that looks like a pasty mass forms on the inside of the
door. The build-up of static charge counteracts the low surface tension of the
hydrocarbon mixture.
If the same liquid is transferred from a statically charged surface to a surface
with no charge, the liquid will be distributed in the usual manner.
The following points are useful:
•
Rinse down the inside of the door with test liquid.
•
Adjust the humidity in the surroundings.
•
Always clean the door with a moist cloth.
•
If there is a lot of static, use a commercial anti-static product.
