It was at least the fourth such incident involving a child falling into a grease pit nationwide since 2017. The outdoor grease pits would be required to have locked manhole covers designed to withstand loads and prevent access by children. Outdoor grease tanks can hold hundreds of gallons and are designed to keep used oil and grease out of sewer systems. Cvechko said she later found out that the restaurant’s grease pit had been recently cleaned and wasn’t completely full of sludge. Cvechko said the screws on the pit’s lid had been removed and were not secured.
