Read： 589 Time：12months ago Source：Transform the World with Simplicity

Industrial liquid chlorine plays an important role in the field of chemical production raw materials. However, due to its strong corrosiveness and toxicity, strict requirements are put forward for the safe storage and transportation of liquid chlorine. In order to ensure the safety of workers and the environment, a series of specifications must be followed.

1. the properties and hazards of liquid chlorine

liquid chlorine is a yellow-green, toxic, flammable and corrosive gas, which can become liquid when cooled to -34.6 ℃ at normal pressure or pressurized to 1.3MPa at normal temperature. The density of liquid chlorine is greater than that of air. Once it leaks, it will spread along the ground, react with metal to generate high-temperature flammable hydrogen, and react violently with many organic compounds, causing fire and explosion hazards.

2. liquid chlorine storage specification

1. The storage place should be cool, dry, well ventilated, away from heat and fire sources, to prevent direct sunlight.
2. The storage container must comply with the pressure vessel specification, and undergo regular safety inspections and maintenance to ensure that the container is intact.
3. Set up a chlorine leak detection alarm in the storage site to regularly detect the chlorine concentration in the storage environment to ensure that it is within a safe range.
4. The storage site shall be equipped with full-time management personnel to be responsible for the reception, distribution and daily inspection of liquid chlorine.

3. liquid chlorine transport specification

1. transport vehicles should meet the requirements of dangerous goods transport vehicles, equipped with corresponding fire fighting equipment and leakage emergency treatment equipment.
2. During transportation, it is necessary to maintain smooth driving, avoid violent vibration, collision and friction, and prevent container damage and leakage.
3. Transport personnel shall be professionally trained, familiar with the nature and hazards of liquid chlorine, and master emergency treatment measures.
4. During transportation, traffic rules and dangerous goods transportation regulations shall be observed to ensure transportation safety.

4. liquid chlorine leakage emergency treatment

1. When liquid chlorine leakage is found, immediately start the emergency plan, organize personnel to evacuate, and report to relevant departments.
2. Use professional gas masks and protective clothing for leakage treatment to avoid direct contact with liquid chlorine.
3. Adopt absorption neutralization method or adsorption method to deal with the leakage of liquid chlorine to ensure that the exhaust gas after treatment meets the emission standard.
4. Clean and disinfect the leakage area to eliminate residual chlorine and other harmful substances.

In conclusion, the regulation of safe storage and transportation of liquid chlorine for industrial use is essential to ensure the safety of raw materials for chemical production. Enterprises should establish a sound safety management system and operating procedures, strengthen the safety training and education of employees, ensure that the storage and transportation process of liquid chlorine meets the specification requirements, and reduce safety risks. At the same time, the government and relevant regulatory authorities should also strengthen the supervision of the storage and transportation of liquid chlorine, discover and rectify potential safety hazards in time, and ensure the safety of people's lives and property.
