3. Inspect resin and catalyst hoses daily for wear or stress at the entry and exits of the boom sections and at the gun 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 hoses may be cut through, causing a hazardous leakage of material which could incr- ease the danger of fire. Also the material may spew onto personnel in the area. In your main plant, store only enough resin for one day’s production.“NO SMOKING” signs must be posted and observed in all areas where resin is stored and/or used.Refer to OSHA Section 1910.94, 1910.106, 1910.107 and consult resin suppliers for more detailed informa- tion.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.Resin must never be stored in an area where MEKP is stored or used.Open-top drums should not be used, due to possible contamination and possible catalyzation from overspray or spillage of MEKP into drum, which could not only se- verely damage the polyester spray system, but might also cause the drum of resin to ignite.When spraying test patterns or purging the gun, always remove the test samples and waste from the building im- mediately and dispose of them in accordance with your material supplier’s recommendations.

2.7 Toxicity of Chemicals

GlasCraft recommends that you consult OSHA Sections 1910.94, 1910.106, 1910.107 and NFPA No. 33, Chap- ter 14, and NFPA No. 91.Contact your chemical supplier(s) and determine the toxicity of the various chemicals used, as well as the best methods to prevent injury, irritation and danger to personnel. Also determine the best methods of first aid treatment for each chemical used in your plant.

2.8 Treatment of Chemical Injuries 2.6 Cured Laminate, Overspray and Laminate Sandings Accumulation

Great care should be used in handling the chemicals (marine resins, catalyst and solvents) used in polyester systems. Such chemicals should be treated as if they hurt your skin and eyes and as if they are poison to your body. For this reason, GlasCraft recommends the use of protective clothing and eye wear in using polyester systems.However, users should be prepared in the event of such an injury. Precautions include: Remove all accumulations of overspray, FRP sandings, etc. from the building as they occur. If this waste is al- lowed to build up, spillage of catalyst is more likely to start a fire, In addition, the fire would burn hotter and longer.Floor coverings, if used, should be non-combustible. Spilled or leaked catalyst may cause a fire if it comes in contact with an FRP product, oversprayed chop or resin, FRP sandings or any other material with MEKP.To prevent this spillage and leakage, you should: 1. Maintain your GlasCraft 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, possible the mold, and may cause a fire. 1. Know precisely what chemicals you are using and obtain information from your chemical supplier on what to do in the event the chemical gets onto your skin or into the eyes, or is swallowed. 2. Keep this information together and easily available so that it may be used by those administering first aid or treating the injured person. 3. Be sure the information from your chemical supplier includes instructions on how to treat any toxic effects the chemicals may have.
