Read： 998 Time：20months ago Source：Transform the World with Simplicity

Ortho-nitroaniline is widely used in the field of chemical raw materials, but its safety problem can not be ignored. In order to ensure the safety of o-nitroaniline during storage and transportation, strict specifications need to be established. This article will detail the safety storage and transportation specifications of o-nitroaniline.

1. the physical and chemical properties of o-nitroaniline

o-nitroaniline is an organic compound with a yellow or orange crystalline solid, melting point of 44-45 ℃, boiling point of 286 ℃, insoluble in water, but soluble in ethanol, ether and other organic solvents. Ortho-nitroaniline is easily oxidized and discolored in air, and is toxic and corrosive.

2. the risk analysis of o-nitroaniline

o-nitroaniline has certain toxicity and corrosiveness, which is harmful to human body and environment. If exposed to or inhaled o-nitroaniline, it may cause skin irritation, eye damage, respiratory problems, etc. In addition, o-nitroaniline may cause safety accidents such as fire or explosion.

3. safety storage specifications for o-nitroaniline

In order to ensure the safe storage of o-nitroaniline, the following specifications need to be followed:

1. The storage place should be dry, ventilated, cool, and away from open flames, heat sources and other hazards.
2. The storage container shall be well sealed to prevent leakage or volatilization of o-nitroaniline.
3. The storage area shall have obvious safety signs and warning signs, and smoking and open fire shall be prohibited.
4. During the storage process, regular safety inspection and maintenance shall be carried out to ensure that the storage equipment and operation are in good condition.

4. safety transportation specifications for o-nitroaniline

In order to ensure the safe transportation of o-nitroaniline, the following specifications need to be followed:

1. Transportation vehicles should comply with relevant standards and have safety facilities such as explosion-proof and fire-proof.
2. Before transportation, check whether the packaging of o-nitroaniline is intact to prevent leakage or volatilization during transportation.
3. Keep running smoothly during transportation to avoid severe vibration or collision.
4. Special personnel shall be assigned to escort during transportation to ensure transportation safety.

emergency treatment measures for 5. o-nitroaniline

If o-nitroaniline leakage or safety accident occurs during storage or transportation, the following emergency treatment measures should be taken:

1. Immediately cut off the power supply and fire source in the accident area to prevent the accident from expanding.
2. Use special equipment or equipment for recycling and disposal of spills to avoid pollution to the environment.
3. First aid and medical treatment shall be given to the injured to avoid casualties.
4. Timely report the accident to the superior competent department and cooperate with relevant departments to investigate and deal with the accident.

In short, in order to ensure the safe storage and transportation of o-nitroaniline in the field of chemical production raw materials, it is necessary to strictly abide by relevant norms and safety operation procedures, strengthen safety management and supervision and inspection, and ensure the safety of personnel and the environment.
