I. Hazardous chemical leakage incidents: Move against the wind and take scientific precautions. In the event of a hazardous chemical leakage, it is essential to stay calm first and quickly determine the direction of the wind. Escaping against the wind is crucial, as toxic and harmful gases usually spread in the direction of the wind; running against the wind allows us to move away from the dangerous area. If the accident occurs indoors, the doors and windows should be closed immediately to prevent toxic gases from spreading further into the room. At the same time, cover the mouth and nose with a wet towel or mask to reduce inhalation of toxic gases. If conditions permit, it is advisable to use a professional gas mask or air respirator. During the evacuation, be careful to avoid contact with any leaked hazardous chemicals, and do not stay in low-lying areas, as toxic gases or liquids may accumulate there. If accidental contact with the leakage occurs, rinse the contaminated skin, eyes, and other affected areas thoroughly with plenty of water as soon as possible, and seek medical attention promptly. II. Fires involving hazardous chemicals: Identifying the situation and responding flexibly. The intensity of fires involving hazardous chemicals is often greater than that of ordinary fires, and they may also pose a risk of explosion. Before escaping, we need to first determine the nature of the flammable hazardous chemicals. If a fire breaks out involving flammable liquids such as oils or organic solvents, water must never be used to extinguish it, as water will cause the liquid to spread, leading to the fire spreading further. At this time, dry powder fire extinguishers or foam fire extinguishers should be used to put out the fire; if the fire gets out of control, one must evacuate the area immediately. When escaping, cover your mouth and nose with a wet towel and crawl forward. The thick smoke generated by fires contains a large amount of toxic substances, and it usually floats above; crawling can help reduce exposure to this smoke. At the same time, follow the directions indicated by the evacuation signs to find the exit; never use the elevator, as a fire could cause it to malfunction and trap people inside. If your clothes catch fire, don’t panic and run around; instead, roll on the ground immediately or use thick clothing to cover the flames and extinguish them. III. Hazardous chemical explosion accidents: Find shelter and protect vital areas. An explosion of hazardous chemicals generates powerful shock waves and flying debris, posing a threat to life safety. When hearing an explosion, quickly find a sturdy shelter such as load-bearing walls, large equipment, or solid tables. Lie down and protect vital areas such as the head, neck, and chest to reduce damage from shock waves and debris. After the explosion, do not rush to get up; first observe the surroundings to ensure there are no dangers such as secondary explosions, and then evacuate along the designated escape route. During the evacuation, be careful to avoid areas that may collapse or contain leaking hazardous chemicals, and also follow the principle of escaping against the wind to reach safe areas. IV. Daily Prevention: Raising Awareness to Prevent Problems Before They Occur In addition to mastering escape skills, daily preventive measures are also crucial. We need to raise awareness of hazardous chemicals and understand the characteristics and hazards of common ones. In daily life and at work, it is necessary to abide by relevant safety regulations and avoid touching unknown chemical substances casually. At the same time, enterprises and relevant organizations should conduct regular safety training and emergency drills for hazardous chemicals, so that employees are familiar with escape routes and emergency response methods. Individuals can also follow some safety knowledge platforms to learn more about the safety of hazardous chemicals and enhance their self-protection awareness.
