On 25.02.2020 at around 07:35 hrs., Brackish water tanker was taken by driver to wash bay for cleaning. When he noticed that there was a WL Unit 06 already parked in the wash bay for cleaning, he decided to wash front portion of tanker without disturbing other vehicle driver, and moved close to the WL unit and applied brake to stop the tanker, but unfortunately the tanker’s brake failed and it hit the WL unit boom hook resulting in damage to wind screen & bumper of the tanker . No injures to personnel.
