Read： 1046 Time：20months ago Source：Transform the World with Simplicity

In the field of chemical production raw materials, urea (carbamide) is a common nitrogen source, widely used in agriculture, industry and other fields. However, due to the physical and chemical properties of urea, there are certain safety risks during its storage and transportation. In order to ensure the safe storage and transportation of urea, corresponding codes and standards need to be observed. The safety
of

1. urea
urea is a white crystalline powder, odorless and tasteless, and easily soluble in water. Urea is irritating to human skin, eyes and respiratory tract, but it is safe to use under regular conditions. However, under high temperature, high pressure or acidic conditions, urea will decompose to produce ammonia and carbon dioxide, which will cause harm to human body and environment.

2. urea storage specification

1. The storage place should be dry, ventilated, moisture-proof, and avoid direct sunlight.
2. Storage should be away from fire, heat, avoid contact with acidic substances.
3. Stacking stability should be checked regularly during storage to prevent safety accidents such as collapse or tilt.
4. In the storage area should be set up obvious safety signs and warning signs, no smoking and open fire.

3. urea transport specification

1. Before transportation, check whether the packaging is intact and whether the logo is clear.
2. During transportation, it should be loaded and unloaded lightly to avoid package damage or urea leakage.
3. Transportation vehicles shall be provided with corresponding safety measures such as fire prevention, explosion prevention and leakage prevention.
4. Avoid dangerous factors such as high temperature, open flame and static electricity during transportation.

4. emergency treatment measures

1. in case of urea leakage, measures should be taken immediately to prevent diffusion, and a large amount of water should be used to flush the leakage area.
2. If skin irritation, eye discomfort and other symptoms occur after contact with urea, rinse immediately with water and seek medical treatment.
3. In case of safety accidents such as fire or explosion, the emergency plan shall be started immediately, and personnel shall be evacuated and the alarm shall be given.

In short, in order to ensure the safe storage and transportation of urea, it is necessary to strictly abide by the corresponding specifications and standards, strengthen the training of management and operators, and improve safety awareness and skills. At the same time, a sound emergency plan and rescue system should be established to ensure that safety accidents can be dealt with and dealt with in a timely and effective manner.
