G. 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.

H. Solvents should be handled in accordance with OSHA Section 1910.106 and 1910.107.

2.4 Catalyst Diluents

Magnum Venus Plastech spray-up and gel-coat systems currently produced are designed so
that catalyst diluents are not required. Magnum Venus Plastech, 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 diluents. In addition, it eliminates any problems
from the diluents being contaminated through rust particles in drums, poor quality control on the
part of the diluents suppliers, or any other reason. If, however, diluents are absolutely required,
contact your catalyst supplier and follow his instructions explicitly. Preferable, the supplier
should premix the catalyst to prevent possible “on the job” contamination while mixing.

WARNING

If diluents are not used, it should be remembered that catalyst spillage, gun, hose and
packing leaks are potentially more hazardous, since each drop contains a higher
concentration of catalyst, and therefore will react quicker with over spray and the leak.

2.5 Cured Laminate, Overspray and Laminate Sandings Accumulation

A. Remove all accumulations of overspray, FRP sandings, etc. from the building as they occur.
If this waste is allowed to build up, spillage of catalyst is more likely to start a fire; in addition, the
fire would burn hotter and longer.

B. Floor coverings, if used, should be non-combustible.

C. Spilled or leaked catalyst may cause a fire if it comes in contact with an FRP product, over-
sprayed chop or resin, FRP sandings or any other material with MEKP.

To prevent this spillage and leakage, you should:

1. Maintain your Magnum Venus Plastech System. Check the gun several times daily for
catalyst and resin packing or valve leaks. REPAIR ALL LEAKS IMMEDIATELY.

2. Never leave the gun hanging over, or lying inside the mold. A catalyst leak in this situation
would certainly damage the part, possibly the mold, and may cause a fire.

3. Inspect resin and catalyst hoses daily for wear or stress at the entry and exits of the boom
sections and at the hose and fittings. Replace if wear or weakness is evident or suspected.

4. Arrange the hoses and fiberglass roving guides so that the fiberglass strands DO NOT rub
against any of the hoses at any point. If allowed to rub, the hose will be cut through, causing a
hazardous leakage of material which could increase the danger of fire. Also, the material may
spew onto personnel in the area.
