Two workers died after gas exposure at an ESL steel plant in Jharkhand. The gas identified in the preliminary account was:

  1. Methane
  2. Carbon monoxide
  3. Sulphur dioxide
  4. Chlorine

Answer

Correct Answer

Carbon monoxide

Explanation

Option B is correct: the report said the two deaths at ESL Steel Limited were due to exposure to carbon monoxide, while a probe was continuing. Methane, sulphur dioxide and chlorine were not identified in the preliminary account. The incident therefore tests recognition of the reported toxic gas, not a general list of industrial pollutants.
