[Chemical Knowledge]：Specification for storage and transport of methacrylic acid

Methacrylic acid safe storage and transportation specification

1. Introduction

Methacrylic acid is an important organic chemical raw material, widely used in polymers, coatings, adhesives and other fields. However, methacrylic acid is flammable, explosive, toxic and other characteristics, and its storage and transportation safety requirements are extremely high. In order to ensure the safety of people's lives and property and improve the safety of storage and transportation of methacrylic acid, it is very important to formulate a set of scientific and reasonable norms.

2. the hazardous characteristics of methacrylic acid

methacrylic acid has the following hazardous characteristics:

1. Flammability: methacrylic acid is exposed to open flames, high heat or oxidants, causing a risk of combustion and explosion.
2. Corrosion: Methacrylic acid is corrosive to metals and can react violently with many substances.
3 toxic: methacrylic acid on the eyes, skin and respiratory tract irritation, inhalation, ingestion or percutaneous absorption of harmful to the body.

3. methacrylic acid storage specification

1. storage place should be cool, ventilated, away from open flame, heat source. The warehouse temperature should not exceed 30 ℃.
2. The storage area shall be equipped with leakage emergency treatment equipment and suitable containment materials.
3. It should be stored separately from oxidants, acids and alkalis, and mixed storage should not be allowed. Explosion-proof lighting and ventilation facilities shall be adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.

4. of methacrylic acid transport specification

1. transport vehicles should have the qualification of dangerous goods transport, it is strictly prohibited to mix with oxidants, acids, alkalis, food chemicals, etc.
2. During transportation, it shall be protected from sun exposure, rain and high temperature. Stay away from kindling and heat sources during stopover.
3. Vehicles shall be thoroughly cleaned after transportation to ensure safety.

5. of methacrylic acid safe operation specification

1. operators must be specially trained, strictly abide by the operating procedures. It is recommended that operators wear self-priming filtering respirator (half mask), chemical safety goggles, anti-static overalls and rubber oil-resistant gloves.
2. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapor leakage into the workplace air. Avoid contact with oxidants, acids and alkalis. Handle lightly to prevent damage to packaging and containers. Equipped with corresponding types and quantities of fire fighting equipment and leakage emergency treatment equipment. Empty containers may leave harmful substances.
Emergency Treatment
for
6. Leakage
evacuate personnel from the contaminated area to the safety zone, isolate them, and strictly restrict access. Cut off the fire source. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and anti-static overalls. Cut off the leak source as much as possible. Prevent from flowing into restricted spaces such as sewers and flood drainage ditches. Small amount of leakage: adsorption or absorption with sand or other non-combustible materials. Can also be washed with a lot of water, wash water diluted into the waste water system. Large leakage: build embankments or dig pits to contain. Cover with foam to reduce steam disasters. Transfer to tank truck or special collector with explosion-proof pump, recycle or transport to waste treatment site for disposal.

7. protective measures

respiratory system protection: when the concentration in the air exceeds the standard, you should wear a self-priming filter gas mask (half mask). In case of emergency rescue or evacuation, it is recommended to wear air respirator.
eye protection: wear chemical safety goggles.
Body protection: wear anti-static overalls.
hand protection: wear rubber oil resistant gloves.
Other protection: Smoking is strictly prohibited at the work site. Maintain good hygiene habits.

8. first aid measures to

skin contact: immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
eye contact: immediately lift the eyelid, with plenty of flowing water or saline rinse thoroughly for at least 15 minutes. Seek medical attention.
inhalation: quickly leave the scene to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
ingestion: gargle with water and drink milk or egg white. Seek medical attention.

summary: Methacrylic acid is an important chemical raw material, and its safe storage and transportation are very important. It is necessary to strictly abide by relevant norms and ensure the safety of people's lives and property.
