Following an explosion at a chemical plant in Spain, an orange toxic cloud appeared near Barcelona on Thursday, 12 February.

Catalonia's regional firefighting department spokesperson said that the explosion occurred after two chemicals, nitric acid and ferric chloride, accidentally got mixed during their delivery to a warehouse in Igualada, according to USAToday.

Latest reports suggest that two people were slightly injured in the accident, which happened at 9:45 am on Thursday. The injured are "out of danger" now.

Spanish authorities requested 65,000 residents of Igualada and four nearby towns to stay indoor for almost two hours.

However, authorities have assured that the chemical combination will not cause any choking sensation.

"Most likely it will cause itchy eyes and a runny nose, but no choking sensation," Ramon Espadaler of Catalonia's interior ministry told, according to the Guardian.
