| [Flash Point] 88 | |
| [Autoignition] 396 | |
| [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. Will burn if involved in a fire. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. | |
| [Fire Potential] May burn but does not ignite readily. | |
| [Ingestion] Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. 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] Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. | |
| [Storage] Store in a cool, dry place. Keep container closed when not in use. Corrosives area. | |
| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Use only in a chemical fume hood. | |
| [Inhalation] May cause severe irritation of the respiratory tract with sore throat, coughing, shortness of breath and delayed lung edema. | |
| [Skin] Causes skin burns. | |
| [Eyes] Causes eye burns. | |
| [Ingestion] May cause burns to the digestive tract. | |
| [Hazards] When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. May polymerize explosively when heated or involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form. | |

| [Personal 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 and clothing to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. | |
| [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. | |
| [Exposure Effects] Abnormal neuropsychologic function has been reported following hydrochloric acid exposure from a leaking tanker truck. | |
