Chinese name:

丙烯酸羟乙酯

Molecular formula：

C5H8O3

Molecular weight：

116.13

Harmful substance composition：

2-hydroxyethyl acrylate

Health hazards：

Irritating to respiratory tract. Inhalation of steam generated by heat can cause death. Can cause eye and skin burns. Percutaneous absorption can cause poisoning and even death. It has sensitization to the skin and burns the mouth and digestive tract by oral administration.

Explosion hazard：

This product is flammable and irritating.

Skin contact：

Take off contaminated clothes immediately and rinse with plenty of flowing water for at least 15 minutes. See a doctor.

Eye contact：

Lift the eyelids immediately and rinse thoroughly with a large amount of flowing water or normal saline for at least 15 minutes. See a doctor.

Inhalation：

Quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. See a doctor.

Ingestion：

Rinse your mouth with water and drink milk or egg white. Seek medical treatment。

Hazard characteristics：

Flammable in case of open fire and high heat. Chemical reactions can occur in contact with strong oxidants. It is easy to self polymerize, and the polymerization reaction intensifies rapidly with the increase of temperature. In case of high heat, the internal pressure of the container increases, and there is a risk of cracking and explosion.

Harmful combustion products：

CO 、CO2

Fire extinguishing method：

Firefighters must wear gas masks and full body fire fighting clothes to extinguish the fire in the upwind direction. Move the container from the fire site to an open place as far as possible. Spray water to keep the containers in the fire site cool until the fire extinguishing is completed. If the container in the fire site has changed color or generated sound from the safety pressure relief device, it must be evacuated immediately. Fire extinguishing agents: fog water, foam, dry powder, carbon dioxide and sand.。

Emergency Management：

Quickly evacuate the personnel in the leakage contaminated area to the safe area, isolate them and strictly restrict their access. Cut off the fire source. It is recommended that emergency treatment personnel wear self-contained breathing apparatus and general work clothes. Do not touch the leakage directly. Cut off the source of leakage as much as possible. Prevent from flowing into restricted spaces such as sewers and flood drainage ditches. Small leakage: mix with sand, dry lime or soda ash. Massive leakage: build a dike or dig a pit for reception. Transfer to tank car or special collector by pump, recycle or transport to waste treatment site for disposal。

Precautions for operation：

Closed operation, local exhaust. Prevent steam from leaking into the air of the workplace. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear self-priming filter gas masks (half masks), chemical safety glasses, anti-static work clothes and rubber gloves. Keep away from kindling and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Welding, cutting and other operations cannot be carried out before removing liquid and steam. Avoid smoke. Avoid contact with oxidants, acids and bases. Containers and conveying equipment shall be grounded to prevent static electricity. During filling, the flow rate shall be controlled and there shall be grounding device to prevent electrostatic accumulation. Fire fighting equipment and leakage emergency treatment equipment of corresponding varieties and quantities shall be provided. Empty containers may leave harmful substances.

Storage precautions：

Store in a cool and ventilated warehouse. Keep away from kindling and heat sources. Protect from direct sunlight. The storage temperature should not exceed 30 ℃. Keep the container sealed and do not contact with air. It shall be stored separately from oxidants, acids and alkalis, and mixed storage shall not be allowed. Provide corresponding varieties and quantities of fire-fighting equipment. The storage area shall be equipped with leakage emergency treatment equipment and appropriate receiving materials。

Engineering control：

Closed operation, local exhaust.

Respiratory system protection：

When the concentration in the air exceeds the standard, you must wear a self-priming filter gas mask (half mask). In case of emergency rescue or evacuation, air respirators should be worn.

Eye protection:

Wear chemical safety glasses.

Physical protection:

Wear anti-static work clothes.

Hand protection：

Wear rubber gloves.

Other protection：

Smoking, eating and drinking are prohibited in the workplace. Wash hands before meals. Shower and change clothes after work. Keep good hygiene habits.

Forbidden compound：

Strong oxidant, strong acid, strong alkali.

Acute toxicity：

LD50：none LC50：none

Thrill：

Rabbit percutaneous: open stimulation test, 500mg, moderate stimulation. Rabbit eye: 20mg / 24h, moderate stimulation.

Biodegradability：

Biodegradable。

Other harmful effects:

Mobility: it is easy to migrate on land, can penetrate into groundwater, can be biodegraded in water body, can be hydrolyzed under alkaline conditions, almost exists in vapor state in the atmosphere, and can react with ozone and hydroxyl in the atmosphere. BOD5 (five-day biochemical oxygen demand): 0.34p/p thod: 1.52p/p adsorption: not easy to adsorb. Enrichment: not easy to enrich. Evaporation: not easy to evaporate.

Waste disposal method：

Incineration is recommended. Reuse containers where they can be used or bury them in specified places.

Packaging method：

None

Precautions for transportation：

Before transportation, check whether the packaging container is complete and sealed. During transportation, ensure that the container does not leak, collapse, fall or damage. Mixed loading and transportation with oxidants, acids, alkalis and edible chemicals are strictly prohibited. Transport vehicles and vessels must be thoroughly cleaned and disinfected, otherwise no other items shall be shipped. During shipping, the assembly position shall be far away from the bedroom and kitchen, and isolated from the engine room, power supply, fire source and other parts. When transporting by road, drive according to the specified route.
