Cyclopentadienyl Manganese Tricarbonyl (CMT) is an economical kind of additives to remarkably increase the octane number of the gasoline and to reduce the harmful ingredients in tail gas of cars. This product is a manganese base composite octane number improver that cooperatively developed by our company. According to the evaluating results in some Chinese refineries, it is proved that this product is a perfect clean gasoline antiknock with very prominent effect.

Hazards and Protection.
StorageStore in a cool, dry, well-ventilated area away from incompatible substances. Do not expose to air. Store under an inert atmosphere.HandlingWash thoroughly after handling. Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Do not breathe dust, vapor, mist, or gas. Keep container tightly closed. Avoid ingestion and inhalation. Handle under an inert atmosphere. Store protected from air. Use only in a chemical fume hood.ProtectionEyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.RespiratorsFollow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary.Small spills/leaksVacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. Place under an inert atmosphere.StabilityStable at normal temperatures in tightly closed containers under an inert atmosphere.IncompatibilitiesOxidizing agents.DecompositionCarbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
Fire fightingWear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.Fire potentialNon-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.HazardsContact with metals may evolve flammable hydrogen gas.Combustion productsFire may produce irritating, corrosive and/or toxic gases.NFPAHealth3 Flammability0 Reactivity0
Exposure limit(s)TLV (as Mn): 0.1 ppm; mg/m3 (as TWA) (skin) (ACGIH 1994-1995). OSHA PEL: C 5 mg/m3 NIOSH REL: TWA 0.1 mg/m3 skinPoison_Class1Exposure effectsMay cause lung damage. IngestionMay be fatal if swallowed. May cause irritation of the digestive tract. May cause central nervous system depression. InhalationMay cause respiratory tract irritation. May cause lung damage. SkinMay cause skin irritation. EyesMay cause eye irritation.
First aid IngestionNever give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2 - 4 cupfuls of milk or water. Wash mouth out with water. InhalationRemove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration. SkinGet medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. EyesFlush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid.
