
The reaction is unpredictable. Prior use of an HHC solvent without incident (corrosion or
explosion) does NOT mean that such use is safe. These solvents can be dangerous alone (as a
clean-up or flushing agent) or when used as a component or a coating material. There is no
known inhibitor that is effective under all circumstances. Mixing HHC solvents with other
materials or solvents such as MEKP, alcohol, or toluene may render the inhibitors ineffective.

The use of reclaimed solvents is particularly hazardous. Reclaimers may not add any inhibitors.
The possible presence of water in reclaimed solvents could also feed the reaction.

Anodized or other oxide coatings cannot be relied upon to prevent the explosive reaction. Such
coatings can be worn, cracked, scratched, or too thin to prevent contact. There is no known way
to make oxide coatings or to employ aluminum alloys to safely prevent the chemical reaction
under all circumstances.

Several solvent suppliers have recently begun promoting HHC solvents for use in coating
systems. The increasing use of HHC solvents is increasing the risk. Because of their exemption
from many state implementation plans as Volatile Organic Compounds (VOCs), their low
flammability hazard, and their not being classified as toxic or carcinogenic substances, HHC
solvents are very desirable in many respects.
WARNING
Do not use Halogenated Hydrocarbon (HHC) solvents in pressurized fluid
systems having aluminum or galvanized wetted parts.
Magnum Venus Products is aware of NO stabilizers available to prevent HHC
solvents from reaction under all conditions with aluminum components in
closed fluid systems. HHC solvents are dangerous when used with aluminum
components in a closed fluid system.

Consult your material supplier to determine whether your solvent or coating contains
Halogenated Hydrocarbon solvents.

Magnum Venus Products recommends that you contact your solvent supplier regarding the best
non-flammable clean-up solvent with the heat toxicity for your application.

If, however, you find it necessary to use flammable solvents, they must be kept in approved,
electrically grounded containers.

Bulk solvent should be stored in a well-ventilated, separate building, 50 feet away from your main
plant.

You should only allow enough solvent for one day’s use in your laminating area.

NO SMOKING signs must be posted and observed in all areas of storage or where solvents and
other flammable materials are used.

Adequate ventilation (as covered in OSHA Section 1910.94 and NFPA No.91) is important
wherever solvents are stored or used, to minimize, confine and exhaust the solvent vapors.

Solvents should be handled in accordance with OSHA Section 1910.106 and 1910.107.
