Many Singaporeans living in the north region spotted a huge reddish-looking smoke cloud over the weekend, with reports coming in from Yishun and even Sengkang.
As it turns out, the smoke was actually a flare from a chemical plant in Pasir Gudang, Johor.
The owner of the chemical plant, Lotte Chemical Titan Malaysia (LCTM), said in a statement that the smoke was caused by a technical issue that resulted in a power dip.
No injuries were reported and there were no damages to the plants.
LCTM is a petrochemical company that produces polyolefins used for household products.
LCTM said that the electrical supply to the plants was restored yesterday following a technical problem with its auxiliary transformer.
They added that the flaring is under control and that they are monitoring the noise readings and air quality to make sure that they are within the limits of safety.
LCTM said that their flaring facilities are designed and constructed to the best engineering technologies to ensure the health, safety and environment of the community are protected.
