| [Fire Fighting] Small Fires: Dry chemical, carbon dioxide, sand, earth, water spray or regular foam. Large Fires: Water spray, fog or regular foam. | |
| [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. Runoff from fire control or dilution water may cause pollution. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use agent most appropriate to extinguish fire. | |
| [Fire Potential] Flammable/combustible material. May be ignited by friction, heat, sparks or flames. | |
| [Ingestion] May cause gastrointestinal irritation with nausea, vomiting and diarrhea. The toxicological properties of this substance have not been fully investigated. | |
| [Ingestion] Never give anything by mouth to an unconscious person. Get medical aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water. | |
| [Ingestion] Seek medical assistance. | |
| [Inhalation] Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. 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. | |
| [Inhalation] Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult. | |
| [Inhalation] Causes respiratory tract irritation. The toxicological properties of this substance have not been fully investigated. Can produce delayed pulmonary edema. | |
| [Skin] Causes skin irritation. | |
| [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. | |
| [Skin] Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician should examine the area if irritation or pain persists. | |
| [Eyes] Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. | |
| [Eyes] Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. | |
| [Eyes] Causes eye irritation. May cause chemical conjunctivitis. | |
| [Storage] Keep container closed when not in use. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. | |
| [Storage] Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. | |
| [Handling] Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. Use with adequate ventilation. | |
| [Handling] All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood. | |
| [Inhalation] Ingestion has caused dyspnea, anoxia, and respiratory failure. Quinone has caused asphyxia and pulmonary damage. | |
| [Skin] May cause burns. | |
| [Eyes] See Skin. | |
| [Ingestion] Vomiting and gi tract irritation have been seen. | |

| [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 minimize contact with skin. | |
| [Personal Protection] Wear appropriate protective gloves, clothing and goggles. | |
| [Respirators] Wear positive pressure self-contained breathing apparatus (SCBA). | |
| [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] Dizziness, headache and delirium have been reported with hydroquinone exposure. Quinone has cause paralysis of the medullary centers and coma. Both quinone and hydroquinone may cause seizures. In rat studies, maternal toxic effects from exposure to hydroquinone included changes in the ovaries, fallopian tubes, and menstrual cycle. Post-implantation mortality was also observed in rat studies. <br>Observed paternal toxic effects from exposure to hydroquinone included changes in the testes, epididymis, sperm duct, prostate, seminal vesicle, Cowper's gland, accessory glands, and male fertility index. <br>Exposure to hydroquinone produced skeletal malformations in chickens and ocular and skeletal malformations in rabbits. | |
| [Exposure Effects] Effects may be delayed. | |
