The dimensions above (51.5 x 51.5 x 6.5 inches) do not reflect the actual dimensions of the device. If the code says the capacity of the 55 gallon drum is 110% of that capacity, the actual unit dimensions of 27 x 27 x 6.5 do not match the code. Do I not understand the containment regulations of the health department? Help me. I need to provide containment under a 55 gallon drum.
