Wearing appropriate protective equipment is the first step to ensure safety when working with hazardous chemicals. If for some reason you cannot wear protective clothing, you can take the following measures to minimize the risk of adverse reactions: 1. **Maintain good ventilation**: - Work in a well-ventilated area to ensure adequate fresh air circulation to reduce the concentration of harmful gases. 2. **Use local exhaust equipment**: - Use a fume hood or other exhaust equipment to prevent harmful gases from accumulating in the work area. 3. **Wear appropriate personal protective equipment (in addition to protective clothing)**: - **Goggles or masks**: Protect eyes and face from splashes and harmful gases. - **Gloves**: Choose gloves that are compatible with the chemicals being handled to prevent chemicals from contacting the skin. - **Respiratory protection**: In an environment with insufficient ventilation, use an appropriate respirator to prevent inhalation of harmful gases. 4. **Avoid skin contact**: - Try to avoid direct contact between hands and other parts of the skin. - Wash hands thoroughly before and after handling to avoid getting chemicals into the mouth, eyes or other sensitive parts. 5. **Proper storage and handling of chemicals**: - Make sure chemicals are stored in safe, clearly labeled containers to avoid misuse or accidental release. - Be familiar with the safety data sheets (SDS) of chemicals and understand their properties and emergency handling methods. 6. **Training and emergency preparedness**: - Ensure that all operators have received relevant safety training and understand the correct operating procedures and emergency measures. - Equipped with necessary emergency equipment, such as eyewash stations, emergency showers and appropriate fire extinguishing equipment. 7. **Reduce exposure time and increase operating distance**: - Minimize the time of contact with chemicals and maintain a certain operating distance to reduce the risk of inhalation or contact. 8. **Keep the work area clean**: - Clean the work area to avoid chemical leaks or splashes to reduce the possibility of accidents. **Important tips**: Although the above measures can reduce risks to a certain extent, they cannot completely replace the important protective role of protective clothing. It is recommended that when conditions permit, you must wear appropriate protective clothing and other necessary protective equipment to ensure your own safety.
