| Hazards and Protection. | |
| Storage | Keep away from heat, sparks, and flame. Keep away from sources of ignition. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. |
| Handling | Wash thoroughly after handling. Use only in a well ventilated area. Ground and bond containers when transferring material. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. |
| Protection | Eyes: 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. |
| Respirators | Follow 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/leaks | Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. A vapor suppressing foam may be used to reduce vapors. |

| Fire fighting | Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Use water spray to keep fire-exposed containers cool. Containers may explode in the heat of a fire. Extinguishing media: Water may be ineffective. In case of fire, use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam. | |||
| 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 | 4 |
| Exposure effects | Prolonged or repeated skin contact may cause dermatitis. Repeated exposure may cause sensitization dermatitis. |
| Ingestion | May cause irritation of the digestive tract. May cause liver damage. |
| Inhalation | May cause respiratory tract irritation. Vapors may cause dizziness or suffocation. |
| Skin | May cause skin irritation. |
| Eyes | May cause eye irritation. |
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. |
| 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 immediately. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. |
| Eyes | Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
