If you do not wear professional protective clothing when exposed to hazardous chemicals, the risk is extremely high, which may cause skin burns, respiratory tract damage, poisoning and even life-threatening. **It is strongly recommended to give priority to the use of compliance protective equipment**. If it is temporarily unavailable due to an emergency, the following emergency measures can be taken to reduce the risk, but professional protection still needs to be sought as soon as possible.： --- ###1. Temporarily reduce the risk of direct exposure 1. **Physical isolation** - Wrap your body with thick, impermeable materials (such as plastic sheeting, rubber gloves, raincoats) to avoid direct skin exposure. -Wear goggles or swimming goggles to protect your eyes, and use a mask or wet towel to filter out some harmful gases (only effective for low concentrations). 2. **Tool replacement** -Use long-handled tools to operate chemicals, maintain a safe distance and reduce limb proximity. --- ### 2. Reduce inhalation and environmental pollution 1. **Ventilation is preferred** - Immediately open all doors and windows, start the exhaust fan or fresh air system, and ensure air circulation. -If it is in a confined space, evacuate quickly and notify professionals to deal with it. 2. **Cover leaks** - Cover liquid leakage with inert materials such as sand, adsorption pads, etc. to avoid volatilization and diffusion. --- ###3. Emergency response and post-mortem measures 1. **Instant cleaning** -If it comes into contact with the skin, rinse with plenty of water for at least 15 minutes (it takes longer for highly corrosive substances) and avoid rubbing. -Take off contaminated clothing and seal it and discard it to avoid secondary contact. 2. **Emergency help** -When symptoms of poisoning such as dizziness and difficulty breathing occur, immediately transfer to a ventilated place and call the emergency number. -Keep chemical labels or photos for reference by medical staff. --- ###4. Strictly prohibited high-risk behaviors - Do not directly touch chemicals or wipe the skin with your hands. -Do not use organic solvents (such as alcohol) to clean the chemically burned area (unless it is clearly safe). -Ignoring mild symptoms and delaying treatment may aggravate the injury. --- ### Key reminder： -**Temporary measures cannot replace professional protection**: The above methods are only used in extreme emergencies, and long-term exposure may lead to chronic injury or cancer. -**Regulations and training**: According to the Occupational Health and Safety Law, employers must provide protective equipment and training, and employees have the right to refuse unprotected high-risk operations. -**Query SDS**: Be sure to check the **Safety Data Sheet (SDS)** of the chemical before operation to understand specific hazards and first aid methods. **There is no trivial matter in life safety, and priority must be given to obtaining protective equipment through formal channels! **
