Authorities on Wednesday released surveillance footage showing the first of two explosions that rocked an Orange County cosmetics plant, killing a male employee and injuring over 100 people.

The blasts occurred roughly 25 minutes apart the morning of November 20th at Verla International in New Windsor.

Officials have determined the fire was accidental in nature and started when static electricity caused the ignition of hexamethyldisiloxane, an ignitable liquid, when a worker was wiping excess product in the plant’s batch room.
The worker, captured on the surveillance video, sustained minor burns.

Authorities initially said one employee was killed and up to 35 people, including seven firefighters, were injured.
