Safety Klean, a provider of products and services for collecting, processing, re-refining, recycling and disposing of hazardous and non-hazardous materials, requested Snyder Environmental assist in the roof repair of a large fluid-holding tank. The tar and gravel built-up roof had rust damage, caused by moisture collection between the layers. The roof had become unsafe and unstable and workers could not safely walk on the roof to perform repairs. Snyder Environmental used an articulating boom lift to extend over the roof and removed the asbestos containing material so that repairs could be made to the roof. The tank is now patched and in service until a new roof can be installed.
