Three scientists were involved in a dangerous hazmat incident at a pharmaceutical lab in Rockland Tuesday night.

A scientist at Barr Laboratories on Quaker Road in Pomona was mixing potassium cyanide, a potentially dangerous chemical, in a flask form when it boiled over and splattered onto his face and mouth. Two other scientists were also exposed.

All were rushed to Nyack Hospital and are in stable condition.

The building, which has 300 employees, was evacuated.

First responders tell News 12 the potential health hazards could have been a lot worse. Deputy Fire Commissioner Chris Kear says that if the chemical were in a gaseous state, it would be an inhalation hazard. It was in a liquid state during the incident.

The hazmat cleanup continued into Wednesday. The incident is being investigated.
