It is a general practice of cleaning washrooms using branded cleaning agents (Harpic). We also use Domex for cleaning floors

Generally Domex, Harpic and other detergents are treated as same

On 08-Nov-09 I had planned to clean the washroom in my house and poured a small quantity of Domex on the washroom floor instead of Harpic (Which I generally use)

As I realized using Domex instead of Harpic, immediately poured small quantity of Harpic on Domex in the floor and left it for 5 mins

After 5 mins I started cleaning the washroom and felt suffocation, but continued to clean after pouring some water

In few seconds I felt giddiness and nausea
