Matters related to mercaptopropionic acid
I. Physical and chemical properties
Mercaptopropionic acid, English name 3 - mercaptopropionic Acid. It is a colorless and transparent liquid with a strong pungent odor. The relative density (water = 1) is about 1.22 and the boiling point is 210 - 212 ° C. It can be miscible with water, ethanol, ether, etc.
II. Overview of hazards
1. ** Health hazards **: It has a strong irritating effect on the eyes, skin, mucosa and upper respiratory tract. After inhalation, it can cause inflammation, edema, spasm, chemical pneumonia, pulmonary edema, etc. After exposure can cause burning sensation, cough, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.
2. ** ENVIRONMENTAL HARMENTS **: May be hazardous to the environment and may cause pollution to water bodies.
3. ** DANGER OF FIRE AND EXPLOPMENT **: This product is flammable and highly irritating.
III. First aid measures
1. ** SKIN CONTACT **: Immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
2. ** EYE CONTACT **: Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.
3. ** Inhalation **: Quickly leave the scene to a fresh place of air. Keep the respiratory tract unobstructed. If breathing difficulties, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
4. ** Ingestion **: Gargle with water, give milk or egg white. Seek medical attention.
IV. Fire protection measures
1. ** Hazardous characteristics **: Combustible in case of open flame, hot topic. Can react with oxidants. Decomposed by hot topic produces toxic sulfide flue gas. Corrosive.
2. ** Harmful combustion products **: carbon monoxide, carbon dioxide, sulfur oxide.
3. ** Fire extinguishing method **: Firefighters must wear gas masks and full-body fire suits to extinguish the fire in the upwind direction. Move the container from the fire site to an open area as much as possible. Spray water to keep the fire site container cool until the fire is extinguished. If the container in the fire site has changed color or produced sound from the safety pressure relief device, it must be evacuated immediately. Extinguishing agent: mist water, foam, dry powder, carbon dioxide, sand.
5. Emergency treatment for leakage
1. ** Emergency treatment **: Quickly evacuate the personnel in the contaminated area of the leakage to the safe area, and isolate them, strictly restrict access. Cut off the source of fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear anti-acid and alkali work clothes. Do not come into direct contact with leaks. Cut off the source of leaks as much as possible. Prevent it from flowing into restricted spaces such as sewers and drainage ditches.
2. ** Small amount of leaks **: Mix with sand, dry lime or soda ash. It can also be rinsed with a lot of water. After the washing water is diluted, it is placed in the wastewater system.
3. ** Large amount of leaks **: Construct a dike or dig a pit for containment. Transfer to a tanker or a special collector with a pump, and recover or transport it to a waste treatment site for disposal.
6. Operation disposal and storage
1. ** Operation precautions **: Closed operation, pay attention to ventilation. Operation is mechanized and automated as much as possible. Operators must be specially trained and strictly follow the operating procedures. It is recommended that the operator wear a self-priming filter gas mask (full mask), wear rubber acid and alkali-resistant clothing, and wear rubber acid and alkali-resistant gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent steam from leaking into the air of the workplace. Avoid contact with oxidants and alkalis. When handling, it should be light and unloaded to prevent damage to packaging and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Harmful substances may remain in the emptied container.
2. ** Storage precautions **: Store in a cool and ventilated warehouse. Keep away from fire and heat sources. It should be stored separately from oxidants and alkalis, and should not be mixed. Equipped with corresponding varieties and quantities of fire-fighting equipment. Storage areas shall be equipped with spill emergency treatment equipment and suitable containment materials.

2. ** Monitoring Methods **: No data available.
3. ** Engineering Control **: Closed operation, pay attention to ventilation. Mechanized and automated as much as possible. Safe shower and eye wash equipment provided.
4. ** Respiratory system protection **: When it is possible to come into contact with its vapor, it is necessary to wear a self-priming filter gas mask (full mask); when it is possible to come into contact with its dust, it is recommended to wear a hood-type electric air supply filter dust respirator.
5. ** Eye protection **: Protection has been made in respiratory system protection.
6. ** Body protection **: Wear rubber acid and alkali resistant clothing.
7. ** Hand protection **: Wear rubber acid and alkali resistant gloves.
8. ** Other protection **: Smoking, eating and drinking water are prohibited at the work site. After work, wash thoroughly. Store clothes contaminated with poisons separately and set aside after washing. Maintain good hygiene habits.
