| Hazards and Protection. | |
| Storage | Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. |
| WHMIS | B2 D2A D2B |
| Handling | Wash thoroughly after handling. Wash hands before eating. Use only in a well ventilated area. Use spark-proof tools and explosion proof equipment. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. 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. |
| Protection | Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact. Neoprene and nitrile rubber are recommended materials. Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area. |
| Respirators | A full facepiece respirator with organic vapor cartridge may be worn up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. |
| Small spills/leaks | Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Clean up spills immediately, using the appropriate protective equipment. Scoop up with a nonsparking tool, then place into a suitable container for disposal. Remove all sources of ignition. |
| Disposal code | 1 |
| Stability | Stable at room temperature in closed containers under normal storage and handling conditions. This material may be sensitive to peroxide formation. Heat and sunlight can contribute to instability. |
| Incompatibilities | Oxidizing agents, aldehydes, acetaldeyde, chlorine, ethylene oxide, acids and isocyanates, hydrogen + palladium, nitroform, oleum, phosgene, potassium t-butoxide, oxygen, trinitromethane, barium perchlorate, tetrafluoroborate, nitric acid, halogen and halogen compounds, chromium trioxide, sodium dichromate + sulfuric acid, aluminum, and aluminum triisopropoxide. It has also been reported to be susceptible to autoxidation and should therRefer to therefore be considered peroxidizable. NFPA manual for more specific information. |

| Fire fighting | Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Use water spray to knock-down vapors. Keep run-off water out of sewers and water sources. | |||
| Fire potential | HIGHLY FLAMMABLE. | |||
| Hazards | Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. May polymerize explosively when heated or involved in a fire. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water. | |||
| Combustion products | Fire may produce irritating, corrosive and/or toxic gases. | |||

| Poison_Class | - |
| Exposure effects | Prolonged or repeated skin contact may cause defatting and dermatitis. May cause allergic skin reaction in some individuals. |
| Ingestion | Can cause drowsiness, unconsciousness, and death. Gastrointestinal pain, cramps, nausea, vomiting, and diarrhea may also result. The single lethal dose for a human adult = about 250 mls (8 ounces). |
| Inhalation | Inhalation of high concentrations may cause central nervous system effects characterized by headache, dizziness, unconsciousness and coma. Inhalation of vapor may cause respiratory tract irritation. May cause narcotic effects. |
| Skin | May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. Prolonged and/or repeated contact may cause defatting of the skin and dermatitis. May cause irritation with pain and stinging, especially if the skin is abraded. |
| Eyes | Produces irritation, characterized by a burning sensation, redness, tearing, inflammation, and possible corneal injury. |
First aid |
|
| Ingestion | If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. Induce vomiting by giving one teaspoon of Syrup of Ipecac. |
| Inhalation | Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. |
| Skin | Get medical aid if irritation develops or persists. Flush skin with plenty of soap and water. |
| Eyes | First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. |
