In order, what are the top three injuries in wastewater?

The correct order of the top three injuries in wastewater involves understanding the most common types of injuries associated with the work environment and tasks performed. Back injuries frequently occur due to heavy lifting, awkward postures, and repetitive strain while handling equipment or containers. Hands are often at risk due to their involvement in manual tasks, including maintenance activities and repairs, which can lead to cuts, crush injuries, and other traumas. Leg injuries can result from slips, trips, and falls, particularly in environments with wet or uneven surfaces.

In contrast, the other options do not align as closely with the typical injury patterns seen in the wastewater industry. For instance, while face injuries can occur, they are generally less frequent than hand or back injuries, which tend to be more prevalent due to the nature of the work involved in wastewater treatment facilities. As such, the sequence of back, hand, and face aligns most accurately with the reported injury statistics in the field.
