MOSCOW - Liquid chlorine spill at a chemical plant in Russia's Perm Territory injured 30 people, local authorities told the Interfax news agency Friday.

Workers at the plant, located at the town of Berezniki in Perm, violated the technological process, triggering the accident.

"30 people have been injured, 27 of them were hospitalized," a local emergencies department spokesperson said, adding the other three people received medical care on the spot.

"The chlorine spill could have been caused by a technical failure and it had already been contained," the regional police department said on its website, adding no threat would be posed to the population.

Local authorities were alerted at 0421 GMT about the spill at the plant's 13th unit, a local emergencies service spokesman told the Interfax. 

Perm Territory Governor Viktor Basargin has ordered the local authorities to provide assistance to those affected and conduct an investigation into the incident.
