| 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. Store under nitrogen. |
| WHMIS | B2 D1A D2B |
| Handling | Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Avoid contact with heat, sparks and flame. Avoid ingestion and inhalation. Use with adequate ventilation. Wash clothing before reuse. 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 | A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use. |
| 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. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors. |
| Stability | May react with oxygen in the air. |
| Incompatibilities | Oxygen, strong oxidizing agents. |
| Decomposition | Carbon monoxide, carbon dioxide. |

| Fire fighting | Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Use water spray to cool fire-exposed containers. Water may be ineffective in extinguishing fire. Do NOT use straight streams of water. In case of fire, use carbon dioxide, dry chemical powder or appropriate foam. | |||
| Fire potential | Flammable liquid and vapor. | |||
| 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. | |||
| Combustion products | Fire may produce irritating, corrosive and/or toxic gases. | |||

| Exposure limit(s) | TLV: 5 ppm; 25 mg/m3 (as CEILING) (ACGIH 1991-1992). NIOSH REL: C 5 ppm (25 mg/m3) |
| Poison_Class | 4 |
| Exposure effects | |
| Ingestion | Causes gastrointestinal irritation with nausea, vomiting and diarrhea. |
| Inhalation | Vapors may cause dizziness or suffocation. Inhalation of vapors will cause coughing or breathing difficulty. Aspiration may cause severe pneumonia. |
| Skin | Causes mild skin irritation. |
| Eyes | Causes mild eye irritation. Contact may cause transient eye irritation. This product rated 1 on rabbit eyes (Toxicology of the Eye). |
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. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. |
| Eyes | Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
