23. MC 331 INSPECTION STEP 4 : INSPECT SECURITY AND INTEGRITY

24. Securement and Integrity ALL CARGO TANKS Anchors Supports Shell and head integrity Circumferential reinforcement 24 MC 331 INSPECTION

25. Supports Alleviate stress on cargo tank Bolsters often welded to pads and tank Pads provide stress relief for attachments When inspecting supports: Assure they look sound Look for corrosion and inspect welds 25

26. Anchors Used to attach tank to frame Designed to prevent motion between tank and chassis Verify anchors are intact, tight, and not damaged Must be accessible unless tank is insulated 26
