Structural strength matters little if landing conditions put volunteers at risk. Sudden immersion creates reflex gasping, and landing improperly in shallow water risks severe spinal or tailbone injury. Adhering to strict water depth safety standards protects participants from striking the bottom:

1. Maintain Vertical Water Clearance: The basin must hold at least 48 inches (4 feet) of water directly below the occupant's resting position. If your stock basin sits at only 28 inches tall, you must recess the base or mount the frame on an elevated platform that holds an extended cylindrical polyethylene liner. The clear depth prevents the participant's feet or pelvis from slamming the basin floor upon full extension.
2. Post Weight Capacity Limits: Clearly mark a strict 250-pound weight ceiling directly on the frame. Exceeding rated weight limits binds the sear, bends the hinges, and creates dangerous instability on turf.
3. Install a Protective Splash Shield: Errant pitches thrown by aggressive participants can easily strike the volunteer. Fasten an impact-resistant sheet of 1/4-inch clear polycarbonate (Lexan) directly between the target assembly and the seating bench. Never use acrylic or plexiglass; acrylic shatters into dangerous shards when hit by a high-velocity baseball.
4. Protect Tank Rim Edges: Wrap heavy-density closed-cell polyethylene foam tubes around all exposed rim edges of the stock tank water basin, securing them with marine-grade zip ties. A volunteer who drops awkwardly must never contact a bare metal or hard plastic edge.
