III. Overview of Hazards
1. ** HEALTH HARMENTS **: Under normal use conditions, triacetin (food grade) is less harmful to human health. However, if it comes into direct contact with the eyes, it may cause mild irritation, resulting in temporary eye discomfort, redness and other symptoms. Skin contact generally does not produce adverse reactions such as allergies, but long-term or large-scale exposure may cause the skin to have a slight degreasing phenomenon. Inhalation of its volatile gases usually does not cause serious harm, but in high-concentration environments, it may cause certain irritation to the respiratory tract, causing symptoms such as cough and asthma.
2. ** Environmental Hazards **: This substance is relatively low in harm to the environment. It has certain biodegradability in the natural environment. In environmental media such as soil and water, it can be gradually decomposed into relatively simple compounds through the action of microorganisms. However, a large amount of leakage into water or soil should still be avoided to prevent potential effects on the local ecological environment.
3. ** Explosion hazard **: Triacetin is flammable and its flash point is relatively high, but it may still cause combustion in case of open flames and hot topics. During storage and use, if it is in a high temperature, high pressure environment or in contact with strong oxidants, there is a certain risk of explosion.

IV. First aid measures
1. ** Skin contact **: If the skin comes into contact with triacetin, the contact part should be rinsed immediately with a large amount of flowing water, and the rinsing time should not be less than 15 minutes. After rinsing, if the skin is still uncomfortable, an appropriate amount of mild skin cream can be applied. If allergies or severe irritation symptoms occur, seek medical attention in time.
2. ** Eye contact **: Once the eyes come into contact with the substance, the eyes should be quickly rinsed with a large amount of flowing water or normal saline. During the rinsing process, the eyeballs should be continuously turned to ensure that all parts of the eyes can be fully rinsed. The rinsing time is at least 15 minutes. After rinsing, you need to go to the ophthalmology department for further examination and treatment as soon as possible.
3. ** Inhalation **: If you accidentally inhale the volatile gas of triacetin, you should immediately transfer it to a fresh place in the air to keep the respiratory tract unobstructed. If you have symptoms such as shortness of breath and cough, you can give oxygen inhalation treatment and send it to the hospital for treatment in time.
4. ** Ingestion **: If you swallow triacetin by mistake, you should rinse your mouth immediately and try to remove the residual Do not try to induce vomiting, so as not to cause further harm. Need to seek medical attention as soon as possible, and the doctor will take corresponding treatment measures according to the specific situation.

5. Fire protection measures
1. ** Hazardous characteristics **: Triacetin is flammable in case of open flame and hot topic. Its combustion will produce harmful gases such as carbon monoxide and carbon dioxide. Chemical reactions may occur in contact with strong oxidants, increasing the danger of combustion and explosion.
2. ** Fire extinguishing methods **: When a fire occurs, foam fire extinguishers, carbon dioxide fire extinguishers, and dry powder fire extinguishers can be used to extinguish the fire. Avoid using water to directly extinguish the fire, because triacetin is not soluble in water, and using water to extinguish the fire may lead to the spread of the fire. Fire extinguishers should wear good protective equipment during the fire extinguishing process, including fire suits, gas masks, etc., to prevent inhalation of harmful gases produced by combustion.

Six. Leak emergency treatment
1. ** Emergency action **: In the event of triacetin leakage, first of all, personnel should be quickly evacuated from the leaking contaminated area to a safe area, and quarantined, strictly restricting access. Cut off the fire source to prevent the leakage from causing a fire. Emergency personnel need to wear self-priming filter gas masks (full masks), wear anti-acid and alkali work clothes, and avoid direct contact with the leakage.
2. ** Small leakage treatment **: For small leaks, it can be absorbed by sand, vermiculite or other inert materials. It can also be flushed with a large amount of water. After the flushing water is diluted, it is placed in the wastewater system.
3. ** Treatment of a large number of leaks **: If a large number of leaks occur, a dike should be built or a pit should be dug for containment. Cover with foam to reduce steam disasters. Transfer to a tanker or a special collector with an explosion-proof pump, and recycle or transport it to a waste treatment site for disposal.

VII. Operation Disposal and Storage
1. * Operation Precautions **: When operating triacetin (food grade), it should be carried out in a well-ventilated environment. Operators need to be specially trained and strictly abide by the operating procedures. Avoid direct contact with eyes and skin. Protective equipment such as protective glasses and gloves should be worn during operation. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment to prevent steam from leaking into the air in the workplace. Avoid contact with prohibited substances such as strong oxidants.
2. ** Storage precautions **: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. Keep the container sealed. It should be stored separately from strong oxidants, and mixed storage should not be avoided. Equipped with corresponding varieties and quantities of fire fighting equipment. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

8. Contact control/individual protection
1. ** Engineering Control **: The production site should provide good natural ventilation conditions, and at the same time install local exhaust equipment to ensure that the concentration of triacetin in the working environment is within a safe range. For equipment and pipelines that may produce leaks, regular inspections and maintenance should be carried out to prevent leaks from occurring.
2. ** Respiratory System Protection **: Under normal operating conditions, special respiratory system protection is generally not required. However, in high concentration environments or in the case of possible leaks, a self-priming filter gas mask (half mask) should be worn. If the concentration is extremely high or in an emergency, an air respirator should be worn.
3. ** Eye Protection **: Chemical safety protective glasses should be worn during operation to prevent triacetin from splashing into the eyes.
4. ** BODY PROTECTION **: Wear anti-toxin penetrating work clothes to avoid direct contact with triacetin on the skin.
