When exposed to hazardous chemicals, not wearing protective clothing will greatly increase the health risk, so **It is strongly recommended to always wear appropriate protective clothing** to protect your own safety. If it is indeed impossible to wear protective clothing, the following measures can reduce adverse reactions to a certain extent, but **cannot completely eliminate the risk**, and the effect of these measures is far less than that of wearing protective clothing.： ### 1. **Avoid direct contact** - Use tools (such as tweezers, pliers, etc.) to manipulate chemicals and avoid direct skin contact. - Try to operate in a well-ventilated area to reduce the risk of inhaling chemicals. ### 2. **Strengthen ventilation** - Ensure that the operating environment is well ventilated, use an exhaust fan or open a window to reduce the concentration of chemical vapor or dust. -Avoid operating chemicals in confined spaces. ### 3. **Use alternative protection** -If there is no protective clothing, you can wear long-sleeved clothing, long trousers and well-closed shoes to minimize skin exposure. -Wear gloves (such as rubber gloves or disposable gloves) and goggles to protect your hands and eyes. ### 4. **Keep your distance** - Try to keep a certain distance from chemicals and avoid inhalation or splashing on the skin. - Operate gently to avoid splashing or aerosols. ### 5. **Emergency treatment** -If the skin or eyes come into contact with chemicals, rinse immediately with plenty of water for at least 15 minutes and seek medical attention as soon as possible. -If you inhale chemicals, immediately transfer to a place with fresh air and seek medical help if necessary. ### 6. **Understand the properties of chemicals** -Before using chemicals, read the safety data sheet (SDS) carefully to understand their hazards and emergency treatment methods. - Avoid mixing unknown chemicals to prevent dangerous reactions. ### 7. **Limit contact time** - Minimize the time to come into contact with chemicals and leave the site immediately after the operation is completed. ### Important reminder： The above measures ** cannot replace protective clothing**, and can only be used as a temporary emergency measure. Long-term or frequent exposure to hazardous chemicals without wearing protective clothing may lead to serious health problems, such as skin damage, respiratory diseases, poisoning and even cancer. **For your safety, please be sure to wear standard protective clothing** and follow safety operating procedures. If conditions do not allow, it is recommended to seek professional help or change to a safer way of working.
