A septic tank truck exploded in a shocking incident that left a worker injured and his shirt torn. The video of the explosion has been widely shared on social media, sparking questions about what caused the blast.

The footage, posted by Facebook user *Tuug Hhggh*, shows the moment the sewage truck suddenly exploded while an employee was securing equipment on top of it. The force of the explosion injured the worker and ripped his clothing.

Following the blast, the employee quickly climbed down from the truck to administer first aid.

Several other septic tank drivers commenting on the post suggested that the explosion may have been caused by gas buildup inside the tank, recommending that lids be left open to allow gases to escape before maintenance or cleaning work.

Authorities are investigating the exact cause of the explosion.
