Indore:
Four workers employed by the Madhya Pradesh Waste Management Project, Pitampur, have been exposed to toxic fumes from a drum containing paint sludge, says the company.
According to reports, the chemical involved is 'thinner' - the same material that is used for removing nail polish.
This facility has come under limelight since it is being readied to receive waste from the Bhopal Gas tragedy plant site.
