Read： 353 Time：13months ago Source：Transform the World with Simplicity

P-cresol is an important raw material for chemical production, which is widely used in pesticide, medicine, dye and other fields. However, p-cresol is toxic and corrosive, so it is necessary to strictly comply with relevant regulations during storage and transportation to ensure safety. This article will detail the safety storage and transportation specifications of p-cresol.

1. the physical and chemical properties of p-cresol

p-cresol is a colorless or slightly yellow crystalline powder with a special odor. It is insoluble in water, but soluble in alcohol, ether, benzene and other organic solvents. The melting point of p-cresol is higher, 35-38 ℃, and the boiling point is 202 ℃. P-cresol is highly corrosive and toxic, and has a stimulating effect on human skin and eyes. Inhalation or ingestion of p-cresol can cause poisoning.

2. safety of cresol storage specification

1. storage place should be dry, ventilated, cool, avoid direct sunlight. The storage temperature should be controlled below 30 ℃, and the relative humidity should not exceed 80%.
2. The storage container should be made of stainless steel or plastic products with good sealing performance, and avoid the use of iron, aluminum and other metal containers to avoid chemical reactions.
3. The storage site shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment, such as sand and linoleum.
4. During the storage process, the sealing performance and storage environment of the container should be checked regularly, and abnormal conditions such as leakage and odor should be found and dealt with in time.

3. the safety of p-cresol transportation specifications

1. Before transportation, check whether the packaging is intact and whether the mark is clear. The packaging shall meet the relevant standards and have sufficient compressive strength and sealing performance.
2. During transportation, light loading and unloading shall be carried out to avoid package damage caused by collision and extrusion. It is strictly prohibited to mix with oxidants, acids, food, etc.
3. Transport vehicles shall be equipped with corresponding fire-fighting equipment and leakage emergency treatment equipment. Drivers and escorts shall be professionally trained and familiar with the knowledge of safe transportation of p-cresol.
4. During transportation, the carriage should be kept dry and ventilated to avoid direct sunlight. The transportation temperature should be controlled below 30 ℃, and the relative humidity should not exceed 80%.

4. leakage emergency treatment measures

1. In case of leakage, the leakage source should be cut off immediately, and the sand, dry lime or soda ash should be mixed and recycled to the waste treatment site for disposal.
2. In case of a large amount of leakage, an embankment or a pit shall be constructed to accommodate it, and then transferred to a tank car or a special collector by pump, and recycled or transported to a waste treatment site for disposal.
3. In case of contact with skin or eyes, rinse immediately with plenty of water for at least 15 minutes and seek medical treatment.

5. safety protection measures

1. Operators must be professionally trained and familiar with the nature of p-cresol and safe operation procedures.
2. Wear protective clothing, gloves, goggles and other personal protective equipment during operation to avoid direct contact with p-cresol.
3. The operation site should be equipped with ventilation devices to maintain air circulation.
4. Regularly carry out health examination for operators to find and deal with occupational hazards in time.

In short, p-cresol, as an important raw material for chemical production, needs to strictly abide by relevant regulations during storage and transportation to ensure safety. By understanding the physical and chemical properties of p-cresol, safety storage and transportation specifications, leakage emergency treatment measures and safety protection measures, production safety and personnel health can be effectively guaranteed.
