Liquid chlorine leakage accident handling procedures and measures

First, what characteristics of the liquid chlorine is?

â‘´ liquid chlorine at room temperature for the yellow-green gas with strong irritating odor;

  (2) It is not flammable by itself, but it can support combustion. 2.5 times heavier than air , not easy to spread in the air;

(3) The pure gas with an absolute pressure of 1 atm is liquid at negative 35 degrees Celsius, and its volume change from liquid phase to gas phase is increased by about 400 times;

(4) Can dissolve in water, but its solubility is not large, and it decreases with increasing temperature;

(5) Chlorine and most organic materials can be strongly reflected. If organic materials and substances are mixed in cylinders and other chlorine containers, under certain conditions, it will cause fierce reflection and cause explosion;

(6) Chlorine is highly toxic and has strong irritation to the mucous membranes of the eyes and respiratory system. It causes congestion and edema in the lungs. The maximum allowable concentration in the air is 0.002 mg/L . Immediately after inhalation , more than 2.5 mg/L will die.

Second, liquid chlorine leak incident handling procedures and measures what?

Answer: (1) On-site consultation ; (2) Reconnaissance and inspection ; (3) Establishment of alert;

(4) effective protection; (5) evacuation of personnel; (6) transfer of chemicals reacted with it;

(7) Dilution and detoxification; (8) Closing off the valve ; (9) Transferring the tank; (10) Chemical neutralization;

(11) soaking hydrolysis ; (12) plugging of the device ; (13) decontamination treatment.

Third, liquid chlorine leak accident disposal operation What are the requirements?

Answer: (1) The setting of the headquarters and the parking of rescue vehicles should be kept at a proper distance from the affected area and set in the upwind direction;

(2) The personnel who enter the poisonous area to carry out rescue operations must be leaner, have sufficient personal protection, and use flowering or spray guns for cover;

(3) When carrying out decontamination operations, it should be carried out in strict accordance with the requirements. At the same time, attention should be paid to observing and disposing of the physical conditions of the persons exposed to the leakage of chlorine, and to carry out health checks;

(4) Persons who are slightly poisoned at the scene should be immediately moved to fresh air, flushed with skin and face that come into contact with toxic substances, and those who have severe symptoms should immediately be sent to the hospital for treatment;

⑸ liquid chlorine production, storage leaks, mainly from the disposal of units responsible for the accident when the accident unit can not be effectively stanch, public security and fire should be under the guidance of action with a unit of engineering and technical personnel;

(6) According to the instructions of the superior, determine the content, time and spokesperson of the press conference.

Fourth, how liquid chlorine storage and transportation?

Liquid chlorine is generally used to store 1000 kg, 500 kg packaging cylinder, a predetermined liquid chlorine cylinder should be << >> chloro bottle Safety Supervision of external coloring, and test writing is stenciled marker; or using the tank 25 t / pot Canned. Liquid chlorine genus virulent, violation number: 23002. Should be stored in a cool, ventilated warehouse.

GRS leak plugging liquid chlorine cylinder group is a newly developed tool plugging liquid chlorine cylinder leaks, the tool set of the original risk completely solved with pressure selector valve, with safety, features easy operation, is the next generation Plugging tools with pressure. ( )

V. tool plugging liquid chlorine cylinder toolset

Liquid chlorine cylinder GRS plugging tool SET product, comprising:

1. Chlorine bottle hydraulic balance lifter;

2. Chlorine bottle needle leakage emergency plugging cover;

3 , emergency blocking device holder;

4. Chlorine bottle leakage emergency plugging device;

  Once the necessary information liquid chlorine spill, attended chlorine cylinder leakage emergency disposal of liquid chlorine and chlorine should get the physical and chemical properties, toxicity profile, poisoning, first aid, etc., and chlorine cylinders familiar with this set of tools to use emergency plugging in a timely manner Leakage disposal of leaking chlorine cylinders.

  Workers entering the isolation area should wear positive pressure self-contained air breathing apparatus and wear protective clothing. The occurrence of liquid chlorine cylinder leakage, driver of the vehicle in transit, guards tank equipped with a gas mask canisters, the unmanned vehicle to a remote office for processing, remain prohibited in densely populated areas or roads.

  Chlorine cylinder leaks usually occur at the following locations:

( 1 ) leakage at the fusible plug

( 2 ) leaking bottle valve

  ( 3 ) Leakage of bottle welds

This new set of GRS liquid chlorine cylinder plugging tool set can be effectively plugging the above-described emergency leakage.
