| Hazard category | Class 3.1 Low flash point flammable liquid (both corrosive and toxic) | ||
| Fire-fighting measures | Fire extinguishing agents: dry powder, carbon dioxide, and dry water react violently to produce toxic gases); Precautions: steam and air form an explosive mixture, when encountering open flame sand, it is strictly forbidden to extinguish the fire with water and foam (explode immediately when encountering high heat, and hydrogen chloride smoke will be produced when encountering water; Firefighters wear self-contained positive pressure respirators and anti-corrosion and fireproof anti-static clothing to extinguish fires in the upwind direction; Water spray cools the container to prevent the container from exploding under pressure, and it is strictly forbidden to contact the leakage with water. | ||
| Emergency treatment | Skin contact: Immediately remove contaminated clothing, rinse with anhydrous ethanol, and then rinse with plenty of running water for at least 15 minutes, seek medical attention; Eye contact: Immediately lift the eyelids, rinse with plenty of running water/saline for more than 15 minutes, and seek medical attention; Inhalation: Quickly leave the scene to a fresh place in the air, keep the airway open, and seek medical attention immediately if breathing is difficult to give oxygen; Ingestion: Gargle, drink milk/egg white, do not induce vomiting, and seek medical attention immediately. | ||
| Packaging, storage, transportation | Packaging: Dry sealed iron drum / fluorinated plastic drum packing, 170kg/drum; Storage: waterless, cool, ventilated explosion-proof warehouse, warehouse temperature ≤ 20°C, sealed and protected from light, away from fire and heat sources, stored separately from water, alcohols, acids, oxidizers, alkalis, dry sand, dry powder fire extinguishers and leakage neutralizers (such as soda ash); Transportation: Transportation of flammable and corrosive liquids with low flash point, strictly prohibited from transportation in rainy days, to prevent moisture in the packaging, light loading and unloading, to avoid collisions, grounding of transport vehicles, equipped with fire-fighting equipment, and strictly prohibiting mixed transportation with water and alcohol. | ||
