Health Minister Dzulkefly Ahmad said nine of the victims are in the intensive care unit and 166 are receiving treatment in normal wards.

Dzulkefly, who had earlier attended a special meeting of the State Disaster Management Committee chaired by Johor Menteri Besar Osman Sapian, refuted a report that a student had died from the chemical pollution.

“I want to stress that the report which went viral about the death of a victim is not true,” he told reporters.

He also advised the public, especially those living in Pasir Gudang, to take preventive measures by wearing R95-type masks at all times and to avoid outdoor activities.

“Avoid being in the polluted area and seek medical treatment immediately if you have nausea, breathing difficulties, vomiting, eyesore and chest pain.

“Don’t take it for granted as it (chemical substance) can absorb into the skin and cause harm. It can also stick to our clothes and be transferred to other people or even family members,” he said.

In a statement tonight, Education Minister Maszlee Malik announced that all 111 schools in Pasir Gudang district will be closed until further notice.
