Q9- As per general guidelines, facilities with large tanks where liquids are transferred into large containers for storage require a minimum of 100% of the volume of the largest container for bulk storage. Further, a minimum additional volume of 10% of the second-largest tank is suggested. There is an additional suggested minimum of 10% of the capacity of this calculated bunded volume to contain rainwater and firewater. The length and the width of the area where the bund is to be located are 150cm and 100cm. (a) Calculate the minimum height of the bund. (2 Mark) (b) The larger the volume of the secondary containment area relative to the primary storage volume, the lower the risk. Another operator considers that the available volume of the secondary containment area will be less than the volume calculated from the above due to the collective volume taken up by all the containers stored within that area, i.e., the space that tanks 2 and 3 occupy within the bund should be considered. As such, they consider additional safety margins. Calculate the available volume in this case. (2 Mark)
