Liquid Chlorine

Liquid chlorine belongs to highly hazardous substances. It has pungent, suffocating and irritating odor. Liquid chlorine is non-combustible, is a strong oxidizing agent, it sustains combustion of many organic substances and is fire hazardous in case of contact with combustible substances. Chlorine is a clear amber-colored liquid about 1.5 times heavier than water and about 2.5 times as heavier than air. Gaseous chlorine is greenish-yellow. Because it is heavier than air, it tends to accumulate at the bottom of poorly ventilated spaces. Avoid contact with chlorine as it is extremely irritating mucous membrane and respiratory tract. Use gas mask or self contained breathing apparatus. Use proper means for loading and unloading of cylinders.
Shelf Life:    Stable under normal conditions.

Uses of liquid chlorine include water purification, sanitation of industrial waste, sewage and swimming pools, bleaching of pulp and textiles. It is also used as raw material chemical in the manufacture of bleaching powder, sodium hypochlorite, PVC plastics, paraffin waxes, synthetic rubbers, pesticides / insecticides, inorganic / organic chemicals, pharmaceuticals etc.

  • Liquid Chlorine is supplied in 65 kg & 900 kg cylinders.
  • Store and handle in accordance with all current regulations and standards in dry, well ventilated area away from external source of heat.
  • Protect the valves and cylinder from physical damage. Keep separated from incompatible substances.
  • Chlorine leakage must be given immediate attention as they become gradually worse.
  • Remove the person from contaminated area and seek immediate medical help or first aid depending upon the severity of the circumstances.
  • Administer artificial respiration if necessary.
  • Clothing contaminated with Chlorine should be removed immediately and the exposed areas washed thoroughly with water.
  • All persons working with chlorine should be acquainted with the proper methods of handling this commodity, the use of gas masks and emergency procedures etc.
  • Chlorine masks full facial type and breathing apparatus should be carried by every one working in an area where chlorine is present.
    Chlorine leaks can be located by ammonia water soaked cotton / cotton rag, which produces dense white fumes with chlorine. Do not put ammonia water on the leaked equipment.
  • Chlorine leakage must be given immediate attention as they become gradually worse.
    If the leakage is extensive it should be reported immediately so that the persons in the effected area could be warned. However, leaking chlorine container must not be washed with water. Use dry chemical to suppress fire.
  • Fine spray of water is also effective.
