On April 26, 2016, at approximately 6:00 p.m., an employee was changing a filter basket that removes fines from the alkaline cleaner. The employee unscrewed the lid and was struck by hot water and detergent (sodium hydroxide mix) under 26 psi, causing second and third degree burns to his upper torso, arms, and back. He was wearing a hard hat, eye protection, hearing protection, boots, and nitro gloves at the time. Chemical resistant clothing was not worn, and lockout/tag-out was not performed, while the filter was being changed.
