According to local authorities in Bushehr Province, investigations have started in the scene of the incident to find out the main cause of the explosion that took place on the oxygen pipeline run by Mobin Petrochemicals, Press TV reported.
A mobile camera footage posted on the social media showed bystanders watching a thick black plume of smoke rising into the sky of Assaluyeh. People could be heard in the video saying that the explosion was related to Mobin.
Mobin is one of the main providers of utility services to petrochemical plants in Asaluyeh, a port where some of Iran’s largest petroleum installations are based.
The oxygen pipeline that exploded on Wednesday was for the transfer of oxygen from Mobin to two petrochemical plants in the region, according to local officials.
However, Mobin’s PR office said the facility had not been involved in the incident, adding that all units in the plant were operating normally.
Governor of Asaluyeh Abdolnabbi Yusefi said that the oxygen pipeline explosion had been caused by welding work.
Yusefi said two people who suffered burns from the explosion had been transferred to a nearby hospital.
Non-fatal incidents have been reported in the Iranian oil and gas facilities in recent weeks amid a new heat wave affecting southern provinces of the country.
Temperatures in Asaluyeh surged to 47 degrees Celsius (116 F) on Wednesday as reported by the official IRNA news agency citing data from the local meteorological department in Bushehr.
