Previously, a loud bang accompanied by strong vibrations allegedly came from the Putri Tujuh Pertamina RU II Dumai Oil Refinery, Riau Province, which occurred on Saturday night at around 22.40 WIB, causing a fire. Meanwhile, Pertamina RU II Spokesperson Dumai Agustiawan told reporters in Dumai in the early hours of Sunday, that five people affected by work accidents in the operator's room have now been taken to Pertamina Dumai Hospital for the best treatment.
