Read： 621 Time：20months ago Source：Transform the World with Simplicity

P-nitroaniline is an important raw material for chemical production, which is widely used in dyes, pharmaceuticals, pesticides and other fields. However, due to its toxicity and flammability, it is necessary to strictly comply with relevant safety regulations during storage and transportation to ensure the safety of personnel and the protection of the environment. This paper will detail the specification of safe storage and transportation of p-nitroaniline.

1. the toxicity
of p-nitroaniline
p-nitroaniline is a toxic compound, which is harmful to human body. Long-term exposure or inhalation of p-nitroaniline may cause chronic poisoning, causing dizziness, headache, nausea, vomiting and other symptoms. In severe cases, it may also damage the liver and kidneys. Therefore, in the process of storage and transportation, it is necessary to take measures to prevent p-nitroaniline from leaking and endangering human health.

2. of nitroaniline storage specification

1. storage place should be dry, ventilated, moisture, and away from fire, heat and other dangerous factors.
2. The storage container shall be well sealed to prevent leakage and volatilization.
3. Storage should be classified, clear identification, to avoid mixing with other chemicals to cause chemical reactions.
4. Check and maintain the storage container regularly to ensure that it is intact.

3. of p-nitroaniline transportation specifications

1. Before transportation, check whether the packaging is intact to prevent leakage during transportation.
2. Observe relevant road traffic safety regulations during transportation, keep the speed stable, and avoid sudden braking and severe vibration.
3. Transportation vehicles shall be provided with safety measures such as fire prevention, explosion prevention and leakage prevention to ensure the safety during transportation.
4. Avoid high temperature, open fire and other dangerous factors during transportation to prevent fire and explosion accidents.

4. emergency treatment measures

1. in case of p-nitroaniline leakage accident, the leakage source should be cut off immediately, and measures such as containment and dilution should be taken to prevent environmental pollution and harm to human health.
2. If the personnel come into contact with p-nitroaniline, they should immediately take off the contaminated clothing, rinse the skin or eyes with a large amount of flowing water, and seek medical treatment in time.
3. In the event of a fire or explosion, call the police immediately and take fire-fighting measures, and evacuate the site personnel to prevent the situation from expanding.

In short, p-nitroaniline, as a toxic and flammable chemical raw material, needs to strictly abide by relevant safety regulations during storage and transportation to ensure personnel safety and environmental protection. At the same time, the preparation and implementation of emergency treatment measures should be strengthened to deal with possible accidents and risks.
