It occurred at 3rd of December

year 1984 sharp in the morning.

Due to leakage of tons of methyl

isocyanate and other harmful

intoxicant gases in one of the

tank.

Resulting in death of millions

and more than 120,000 suffers.

BACKGROUND AND CAUSE

The Union Carbide India Limited (UCIL) plant was

established in 1969 near Bhopal.

The Following points are to be noted for leading

the gas leak :-

Economy.

Staff reduced, uneducated.

Poor maintenance of the plant.

Safety rules not followed.

The tank 610 was containing tons

of Methyl Isocyanate (MIC).

Large amount of water entered the

tank while cleaning out the pipes.

Runway reaction started due to

coroison.

Increase in the temperature inside

the tank.

The tank then gave off a large

volume of toxic gases forcing the

emergency release of pressure.
