| [Flash Point] 109 | |
| [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. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam. | |
| [Fire Potential] This material is probably combustible. | |
| [Ingestion] Get medical aid. Wash mouth out with water. | |
| [Inhalation] Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. | |
| [Skin] Get medical aid. 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. | |
| [Storage] Store in a cool, dry place. Store in a tightly closed container. | |
| [Handling] Wash thoroughly after handling. Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on skin, or on clothing. Use only in a chemical fume hood. | |
| [Inhalation] May cause respiratory tract irritation. Exposure produces central nervous system depression. May be harmful if inhaled. May cause liver damage. | |
| [Skin] Causes skin irritation. May be harmful if absorbed through the skin. | |
| [Eyes] Causes eye irritation. | |
| [Ingestion] Harmful if swallowed. May cause irritation of the digestive tract. May cause burning sensations, coughing, wheezing, laryngitis, shortness of breath and headache. | |
| [Hazards] When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | |
