The safe storage and transportation specification
of liquid alkali
1. Introduction

In the field of chemical production raw materials, liquid alkali is an important alkaline absorbent, widely used in many chemical processes. However, due to its strong corrosiveness and irritation, liquid caustic soda needs to strictly abide by certain safety regulations during storage and transportation to ensure personnel safety and environmental protection. This article will elaborate the safe storage and transportation specification of liquid caustic soda.

2. the physical and chemical properties of liquid alkali

liquid alkali, also known as sodium hydroxide solution, is a colorless and transparent liquid with strong corrosiveness and alkalinity. It can react with acids, metals, non-metals and some organic compounds to generate a lot of heat and gas. The corrosiveness of liquid alkali increases with its concentration, and high concentrations of liquid alkali can quickly corrode metals and plastics.

3. safe storage specifications for liquid caustic soda

1. Storage facilities: liquid caustic soda should be stored in a cool, dry, well-ventilated special warehouse, avoid direct sunlight and high temperature. The warehouse floor shall be treated with anti-corrosion and anti-leakage facilities shall be provided.
2. Storage container: liquid alkali should be stored in a special plastic or glass container, and metal containers should be avoided to avoid corrosion. The container should be well sealed to prevent leakage.
3. Storage identification: Obvious warning identification shall be provided on warehouses and containers, including chemical name, danger, emergency measures and other information.
4. Inventory management: Establish a strict inventory management system, regular inventory, to ensure that the accounts match. Report and handle the abnormal situation in time.

4. liquid caustic soda safety transport specification

1. transport vehicles: should be selected with anti-corrosion, anti-leakage function of special transport vehicles for liquid caustic soda transport. The vehicle should be kept in good working condition to ensure safety during transportation.
2. Transport packaging: The transport packaging of liquid caustic soda should meet relevant standards and have sufficient strength and tightness to prevent leakage. The packaging shall be clearly marked, including the name of the chemical, hazard, emergency measures and other information.
3. Transportation routes: Choose reasonable transportation routes and avoid passing through sensitive areas such as densely populated areas and water source protection areas. During transportation, you should try to keep running smoothly and reduce bumps and vibrations to prevent package damage and leakage.
4. Transport personnel: Transport personnel should be professionally trained to understand the nature of liquid caustic soda and safe operation procedures, and have the ability to respond to emergencies.

5. emergency measures

During the storage and transportation of liquid caustic soda, in case of leakage and other emergencies, the following emergency measures should be taken:

1. Personnel evacuation: immediately evacuate the personnel near the leakage area, set up a cordon, and prohibit irrelevant personnel from entering.
2. Cut off the fire source: Turn off the power supply and open fire in the leakage area to prevent fire or explosion.
3. Protective measures: Wear protective clothing, gloves, goggles and other personal protective equipment to avoid direct contact with liquid caustic soda.
4. Leakage treatment: Use special absorption materials to clean up the leaked liquid caustic soda to avoid flowing into sewers or drains. Place the cleaned waste in the designated hazardous waste disposal site.

6. conclusion

liquid caustic soda is an important material in the field of chemical production raw materials, and its safe storage and transportation are very important. By strictly complying with safety regulations and taking effective protective measures and emergency measures, the safety risks of liquid caustic soda during storage and transportation can be reduced, and the safety of personnel and environmental protection can be guaranteed.
