The following cleaning agents are not allowed !
Trichloraethane (halogens, incombustible)

Trade names:
Clorothene, Genklene, Solvethane, Baltane.
When ignited from an extraneous source the above
release highly toxic, corrosive decomposition by
products. Their use in electrical machines is
therefore strictly prohibited.
 Trichloroethylene, perchloroethylene
(halogens, incombustible)
The same disadvantages as trichloroethane, plus
higher toxicity. Not released by health authorities.
Swiss toxicity class: Trichlo. 4, Perchlo.5
 "Safety" solvents
Trade names:
Pentex 77, SS 26
Turco-Solv, Diluan T, Disolver
Gamlen-Solvent 26
Inner-El-Mot-Cleaner, etc.
The claim to additional safety is mainly based on the
higher flash point of these products. Since they also

dry very quickly however, consumption rates are
appreciably higher, resulting in heavier
contamination of the work-shop atmosphere. All
"safety" solvents contain varying proportions of
halogens solvents and therefore are not to be used
for the same reasons.
 Fluorinated solvents (halogens, incombustible)
Trade names:
Freon-TF (Du Pont)
Flugene (Rhone-Poulenc)
General use of these products is strictly
prohibited. They may only be used in special
cases by qualified specialists.
 Non-halogens, volatile solvents
Examples:
Acetone, Nitro-thinner, Volatile benzene
Use of these products is prohibited, on account of
the fire and explosion hazard.
