Calcium hydroxide in the field of chemical production of raw materials in the safety of storage and transportation specifications

1. Introduction

calcium hydroxide as a common chemical production of raw materials, widely used in many fields. However, if it is stored and transported improperly, it may cause a safety accident. Therefore, it is very important to understand and master the safe storage and transportation regulations of calcium hydroxide. This article will detail the physical properties, chemical properties, hazards and safety of calcium hydroxide storage and transportation specifications, designed to ensure the safety of calcium hydroxide in the production, storage and transportation process.

2. the physical properties of calcium hydroxide, chemical and dangerous

calcium hydroxide, also known as hydrated lime or slaked lime, is an inorganic compound with strong alkalinity. Its physical properties include white powder or granular, non-toxic, tasteless, non-flammable, non-explosive, alkaline, easy to absorb moisture. Calcium hydroxide is chemically active and can neutralize with acid to generate salt and water. In addition, calcium hydroxide is corrosive and irritating to the skin, eyes and respiratory tract.

3. calcium hydroxide safety storage specification

1. The storage place should choose a dry, ventilated, cool place, avoid direct sunlight and high temperature.
2. The storage container should use plastic or glass container with good sealing performance, and avoid using metal container.
3. In the process of storage, the container should be checked regularly for leakage, and the leakage should be dealt with in time.
4. The storage area shall be provided with obvious safety signs and equipped with corresponding fire fighting equipment.

4. calcium hydroxide safety transportation specifications

1. Before transportation, the transportation vehicle should be fully inspected to ensure that the vehicle is in good condition.
2. Keep running smoothly during transportation to avoid severe vibration, collision and friction.
3. Transportation vehicles shall be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
4. Avoid high temperature and open fire during transportation to prevent calcium hydroxide from burning or exploding.

5. calcium hydroxide leakage emergency treatment measures

1. in case of calcium hydroxide leakage, stop the leakage source immediately and take measures to prevent the leakage from spreading.
2. Flush the leaking area with plenty of clean water and introduce the rinse water into the waste water treatment system.
3. For small spills, sand, dry lime or soda ash can be mixed and collected and placed in a closed container for disposal.
4. For large spills, embankment or pit containment shall be established and pumped into the tank car or special collector.

6. conclusion

calcium hydroxide as a common chemical production raw material, its safety storage and transportation is very important. By understanding and mastering the physical properties, chemical properties, dangers and safety of calcium hydroxide storage and transportation specifications, it can effectively prevent the occurrence of safety accidents and ensure the safety of production, storage and transportation. Therefore, relevant enterprises and personnel should strictly abide by the safe storage and transportation specifications of calcium hydroxide to ensure safety in the production process.
