Flash Point: -20 deg C. Danger! Aspiration hazard if swallowed. Can enter lungs and cause damage. May cause respiratory and digestive tract irritation. May cause eye and skin irritation. May cause central nervous system depression. May cause liver and kidney damage. Highly flammable. May form explosive peroxides. Target Organs: Kidneys, central nervous system, liver, cardiovascular system.
- 3. Eye: May cause mild eye irritation. Skin: May be absorbed through the skin in harmful amounts. May cause irritation with burning pain, itching and redness. Ingestion: Ingestion of large amounts may cause gastrointestinal irritation. May cause liver and kidney damage. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure. May cause vascular collapse and damage. Aspiration of material into the lungs may cause chemical pneumonitis, which may be fatal. Potential Health Effects
- 4. Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. May cause respiratory tract irritation. May be fatal if exposed to high concentrations. Chronic: Prolonged or repeated skin contact may cause defatting and dermatitis. May cause liver and kidney damage.
- 5. First Aid Measures Eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. Do NOT allow victim to rub or keep eyes closed. Skin: Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid if irritation develops or persists. Wash clothing before reuse. Ingestion: Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Possible aspiration hazard. Get medical aid immediately. Inhalation: Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. Do NOT use mouth-to-mouth resuscitation. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. Notes to Physician: Treat symptomatically and supportively.
- 6. Fire Fighting Measures General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extremely flammable. Material will readily ignite at room temperature. Use water spray to keep fire-exposed containers cool. Liquid will float and may reignite on the surface of water. Vapors may be heavier than air. They can spread along the ground and collect in low or confined areas. May polymerize explosively when involved in a fire. Containers may explode when heated. Extinguishing Media: Water may be ineffective. This material is lighter than water and insoluble in water. The fire could easily be spread by the use of water in an area where the water cannot be contained. Do NOT use straight streams of water. For large fires, use water spray, fog or regular foam. For small fires, use dry chemical, carbon dioxide, water spray or regular foam. Cool containers with flooding quantities of water until well after fire is out.
- 7. Accidental Release Measures General Information: Use proper personal protective equipment. Spills/Leaks: Absorb spill with inert material (e.g. vermiculite, sand or earth), then place in suitable container. Avoid runoff into storm sewers and ditches which lead to waterways. Clean up spills immediately, observing precautions in the Protective Equipment section. Wear a self contained breathing apparatus and appropriate Personal protection. (See Exposure Controls, Personal Protection section). Scoop up with a nonsparking tool, then place into a suitable container for disposal. Remove all sources of ignition. Provide ventilation.
- 8. Handling and Storage Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well-ventilated area. Do not reuse this container. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Do not get on skin or in eyes. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Storage: Store in a tightly closed container. Store in a cool, dry, well- ventilated area away from incompatible substances. Flammables- area.
- 9. Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to keep airborne concentrations below the permissible exposure limits.

- 12. Chemical Stability: Stable at room temperature in closed containers under normal storage and handling conditions. Explosive peroxides may form on concentration. Peroxides can be detonated by friction, impact, or heating. Peroxide formation may occur in containers that have been opened and remain in storage. Normally stable; however, on long term storage, materials containing similar functional groups form peroxides of unknown stability. Conditions to Avoid: Incompatible materials, ignition sources, excess heat, oxidizers. Incompatibilities with Other Materials: Strong oxidizing agents, nitrogen dioxide. Hazardous Decomposition Products: Carbon monoxide, irritating and toxic fumes and gases, carbon dioxide.
- 13. Chemical waste generators must determine whether a discarded chemical is classified as a hazardous waste. US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3. Additionally, waste generators must consult state and local hazardous waste regulations to ensure complete and accurate classification. RCRA P-Series: None listed. RCRA U-Series: CAS# 110-82-7: waste number U056; (Ignitable waste).
- 14. This data sheet is very useful because it allows you to know the components used in making a certain product, it will show the type of chemicals used and it also provides details of the products' physical properties and also chemical property Being fully aware of the chemicals they are handling, employees would exert extra caution when dealing with the components. Since there is the MSDS, people take precaution. They will be more careful and watchful when dealing with the chemicals, they will not be careless. It is important that the effects are identified as well as understood so that preventive and corrective action can be taken.
- 15. The details in the material safety data sheet are vital to all so that in case we encounter such products we know how to deal with them.
