supplier regarding the best non-flammable clean-up sol-vent 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, sepa-rate building, 50 feet away from your main plant.You should allow only 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 flam- mable materials are used.Adequate ventilation (as covered in OSHA Section 1910.94 and NFPA No. 91) is important wherever sol- vents are stored or used, to minimize, confine and ex- haust the solvent vapors.Solvents should be handled in accordance with OSHA Section 1910.106 and 1910.107. The reaction is unpredictable. Prior use of an HHC sol-vent without incident (corrosion or explosion) does NOT mean that such use is safe. These solvents can be dan- gerous 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. Furthermore, the mixing of HHC solvents with other materials or solvents, such as MEK, alcohol, and tolu- ene, may render the inhibitors ineffective.The use of reclaimed solvents is particularly hazardous. Reclaimers may not add any inhibitors. Also, the pos- sible presence of water in reclaimed solvents could 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 con- tact. There is no known way to make oxide coatings or to employ aluminum alloys which will 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 (VOC’s), their low flam- mability hazard, and their not being classified as toxic or carcinogenic substances, HHC solvents are very desir- able in many respects.

2.4 Catalyst Diluents

GlasCraft spray-up and gel-coat systems currently pro- duced are designed so that catalyst diluents are not re- quired. GlasCraft, therefore, recommends that diluents not be used. This avoids the possible contamination which could lead to an explosion due to the handling and mixing of MEKP and diluent. In addition, it eliminates any problems from the diluent being contaminated through rust particles in drums, poor quality control on the part of the diluent supplier, or any other reason. If, however, di- luents are absolutely required, contact your catalyst sup- plier and follow his instructions explicitly. Preferably, the supplier should premix the catalyst to prevent possible “on the job” contamination while mixing.

WARNING

Do not use Halogenated Hydrocarbon solvents in pres- surized fluid systems having aluminum or galvanized wetted parts. Consult your material supplier to determine whether your solvent or coating contains Halogenated Hydrocar- bon Solvents. GlasCraft recommends that you contact your solvent

NOTE

GlasCraft is aware of NO stabilizers available to prevent Halogenated Hydrocarbon solvents from reaction under all conditions with aluminum components in a closed fluid system. TAKE IMMEDIATE ACTION... Halogenated Hydrocarbon solvents are dangerous when used with aluminum components in a closed fluid system.

WARNING

If diluents are not used, it should be remembered that catalyst spillage, gun, hose and packing leaks are poten- tially more hazardous, since each drop contains a higher concentration of catalyst, and therefore will react quicker with overspray and the like.

2.5 Uncured Liquid Resin

Resin should be stored in a well ventilated building at least 50 feet from your main plant. In addition, the stor- age temperature should not exceed 75 degrees F.
