Workers should be thoroughly informed of the hazards that may result from improper handling of MEKP, especially in regards to contamination, heat, friction and impact. They should be thoroughly instructed regarding the proper action to be taken in the storage, use and disposal of MEKP and other hazardous materials used in the laminating operation. In addition, users should make every effort to: 1. Store MEKP in a cool, dry place in original containers away from direct sunlight and away from other chemicals. 2. Keep MEKP away from heat, sparks and open flames. 3. Prevent contamination of MEKP with other materials, including polyester overspray and sandings, polymerization accelerators and promoters, brass, aluminum and non-stainless steels. 4. Never add MEKP to anything that is hot, since explosive decomposition may result. 5. Avoid contact with skin, eyes and clothing. Protective equipment should be worn at all times. During clean-up of spilled MEKP, personal boat safety equipment, gloves supplier and eye protection must be worn. Fire fighting equipment should be at hand and ready. 6. Avoid spillage, which can heat up to the point of self-ignition. | | with copious quantities of clean water and disposed of in accordance with the catalyst manufacturer's instructions. The extent to which the user is successful in accomplishing these ends and any additional recommendations by the catalyst manufacturer determines largely the safety that will be present in his operation. | | | | | | | | | | 2.3 Clean-Up Solvents and Resin Diluents | | | | | | | | | | WARNING A hazardous situation may be present in your pressurized fluid system! Hydrocarbon Solvents can cause an explosion when used with aluminum or galvanized components in a closed (pressurized) fluid system (boat pumps, boat heaters, Alters, valves, spray guns, boat tanks, etc.) The explosion could cause serious injury, death and/or substantial property damage. Cleaning agents, coatings, boat paints, etc. may contain Halogenated Hydrocarbon Solvents. Some GlasCraft spray equipment includes aluminum or galvanized components and will be affected by Halogenated Hydrocarbon Solvents. | | | | | | | | | | There are three key elements to the Halogenated Hydrocarbon (HHC) solvent hazard. 1. The presence of HHC solvents. 1,1,1- Trichloroethane and Methylene Chloride are the most common of these solvents. However, other HHC solvents are suspect if used; either as part of paint or adhesives formulation, or for clean-up flushing. | | | | | | | | | | 7. Repair any leaks discovered in the catalyst system immediately, and clean up the leaked catalyst at once in accordance with the catalyst manufacturer's instructions. 8. Use only original equipment or equivalent parts from GlasCraft in the catalyst system (i.e.: hoses, fittings, etc.) because a dangerous chemical reaction may result between substituted parts and MEKP. 9. Catalyst accumulated from the purging of hoses or the measurement of fluid output deliveries should never be returned to the supply tank. such catalyst should be diluted | | 2. Aluminum or Galvanized Parts. Most handling equipment contains these elements. In contact with these metals, HHC solvents could generate a corrosive reaction of a catalytic nature. 3. Equipment capable of withstanding pressure. When HHC solvents contact aluminum or galva nized parts inside a closed container such as a pump, spray gun, or fluid handling system, the chemical reaction can, over time, result in a build-up of heat and pressure, which can reach explosive proportions. When all three elements are present, the result can be an extremely violent explosion. the reaction can be sustained with very little aluminum or galvanized metal; any amount of aluminum is too much. | | | | | | | | | 15 | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
