must emphasize that hazardous chemicals are highly risky and basic safety operating procedures should not be violated under any circumstances. Standard operating procedures clearly require that appropriate protective clothing, gloves, goggles and other protective equipment must be worn when contacting hazardous chemicals. This is to minimize direct damage to the skin, respiratory tract and eyes, and prevent chemical burns, poisoning, allergic reactions and other serious health risks. If you are exposed to hazardous chemicals without wearing protective clothing in an accident or emergency, please be sure to respond according to the following emergency measures (note: these measures are only temporary emergency measures and cannot replace the correct use of personal protective equipment): 1. Immediately leave the contaminated site: quickly reach a safe area to avoid further contact. 2. Remove contaminants as soon as possible: If the chemical adheres to the skin or clothing, take off the contaminated clothing as soon as possible and be careful not to spread the chemical to other parts. 3. Adequate cleaning: Use plenty of running water (or appropriate diluent, depending on the nature of the chemical) to thoroughly rinse the affected area. For those whose eyes are contaminated, rinse with water for at least 15 minutes immediately and seek professional medical help. 4. Emergency medical treatment: Contact the emergency center or go to the hospital as soon as possible to explain the type and situation of the chemical you have been exposed to so that you can get targeted treatment. 5. Report the accident: Follow the accident reporting procedures of the workplace and report the situation in a timely manner so that further protective and treatment measures can be taken. Please note that these emergency measures can only reduce the risk of injury to a limited extent, but they can never replace the importance of using protective equipment under normal circumstances. If there are hazardous chemicals in the working environment, please be sure to take adequate protective measures and strictly abide by relevant safety operating procedures. If you have any questions about safety measures, it is recommended to consult a safety expert or relevant competent authority as soon as possible to ensure the safety of yourself and others. The above information is for reference only. Specific operations should be carried out in accordance with the nature of the chemicals involved and local safety regulations, and under professional guidance.
