| Hazards and Protection. | |
| Storage | Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. |
| WHMIS | D1A |
| Handling | Wash thoroughly after handling. Use only in a well ventilated area. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid contact with heat, sparks and flame. Do not ingest or inhale. |
| 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. Avoid runoff into storm sewers and ditches which lead to waterways. Provide ventilation. |

| Fire fighting | Wear 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. Use water spray to keep fire-exposed containers cool. Containers may explode when heated. Extinguishing media: Use water spray to cool fire-exposed containers. Do NOT use straight streams of water. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use water spray, fog or regular foam. | |||
| Fire potential | Moderately flammable. Combustible. | |||
| Hazards | Containers may explode when heated. | |||
| Combustion products | Toxic fumes may be generated. | |||

| Poison_Class | 3 |
| Exposure effects | CNS effects include headache, dizziness, altered mental status, confusion (lethargy progressing coma), seizures, syncope; occur secondary to CNS hypoxia, usually with levels > 20%. |
| Ingestion | Aspiration hazard. May be harmful if swallowed. Causes digestive tract irritation. |
| Inhalation | May be fatal if inhaled. Causes respiratory tract irritation. Aspiration may cause respiratory swelling and pneumonitis. |
| Skin | Causes mild skin irritation. |
| Eyes | Causes mild eye irritation. |
First aid | |
| Ingestion | Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. |
| Inhalation | Get medical aid immediately. Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask. |
| 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 | Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. |
