The temperature at the site of the Rajaei port explosion reached 1,400 degrees Celsius, making water immediately evaporate and ineffective in extinguishing the container fires, the head of Tehran's fire department said on Sunday.
Ghodratollah Mohammadi told ISNA that the fires in the incident occurred within closed containers holding various materials, including food, car parts, and bitumen.
Mohammadi said that firefighters had to open the containers to control the blaze, adding that using water on a container filled with bitumen, for example, was not feasible.
