[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. Non-combustible, substance itself does not burn but may decompose upon heating to produce irritating, corrosive and/or toxic fumes. Extinguishing media: Do NOT get water inside containers. For small fires, use dry chemical, carbon dioxide, or water spray. For large fires, use dry chemical, carbon dioxide, alcohol-resistant foam, or water spray. Cool containers with flooding quantities of water until well after fire is out. | |
[Fire Potential] Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. | |
[Ingestion] Do NOT induce vomiting. 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] Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration. | |
[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] Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed. Extensive irrigation is required (at least 30 minutes). | |
[Storage] Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. | |
[Handling] Wash thoroughly after handling. Use with adequate ventilation. Minimize dust generation and accumulation. Do not get in eyes, on skin, or on clothing. Keep container tightly closed. Avoid ingestion and inhalation. | |
[Inhalation] Effects may be delayed. May cause respiratory tract irritation. | |
[Skin] Causes skin irritation. May cause skin burns. Effects may be delayed. May cause discoloration, erythema, swelling, and the formation of papules and vesicles. | |
[Eyes] Causes eye irritation. May cause eye burns. Quinones were suspected and shown to cause discoloration of the cornea. May cause visual disturbances. | |
[Ingestion] Harmful if swallowed. May cause irritation of the digestive tract. Ingestion may cause the following: a decreased number of erythrocytes in the blood, decreased hemoglobin levels in the blood and depressed phagocytic activity of leukocytes. | |
[Hazards] Contact with metals may evolve flammable hydrogen gas. | |

[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 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. | |
[Exposure Effects] Prolonged or repeated skin contact may cause dermatitis. Prolonged contact may cause severe eye irritation or burns. | |
