Adequate ventilation. Spare tank for emergency transfer Dike wall, emergency scrubber etc.
Leak, spill handling
If the leak in piping, shut off the Chlorine supply. If the leak is from cylinders, position the cylinder so that leak will be in gaseous phase. Contain Liquid spills. Do not pour water on leak containers.
Nuetralise the waste Chlorine or spills with alkaline solutions such as Caustic Soda, Soda ash or slaked lime etc.
EMERGENCY I FIRST – AID MEASURES
Fire extinguishment Non flammable gas
Seamless steel, seamless copper flxible piping are used for handling liquid Chlorine
Personal protective equipment
Self contained Breathing Apparatus Gas filters Protective Clothing.

First – Aid Antidotes
Remove the victim from contaminated area. Remove contaminated clothing. Provide fresh air circulation. Oxygen can be administered by trained person. If breathing ceased, start artifical respiration.
One volume of liquid Chlorine expands 457 volumes of gas. Position the leak container so that leak spot comes at top, only gas escape rather than liquid.
