Chloroform is slowly oxidised by air in the presence of light to an extremely poisonous gas, carbonyl chloride, also known as phosgene. It is therefore stored in closed dark coloured bottles completely filled so that air is kept out.
2CHCl₃ + O₂ → 2HCl + 2 COCl₂

Because if chloroform is kept in air then it react with oxygen to form phosgene gas.
