Here's an excerpt from the CCA 7-man mechanics book:

B. The bean bag will be dropped to mark the appropriate spot:
1. When a scrimmage kick ends inbounds. (This marks the Post Scrimmage Kick enforcement spot. Normally only one official will mark this spot with his bean bag.)
2. When the covering official actually sees a live ball fumbled anywhere on the field.
3. When a hand-off or backward pass occurs beyond the neutral zone or when there is no neutral zone.
4. When an eligible Team A pass receiver voluntarily goes out of bounds.
5. When an eligible receiver fails to return inbounds immediately after being blocked out of bounds.
6. When a Team A player goes out of bounds during a free or scrimmage kick down.
7. When a Team A player illegally touches a free or scrimmage kick.
8. When a Team B player intercepts a forward pass, fumble or backward pass between his five yard line and the goal line.
9. When a Team B player catches a free or scrimmage kick between his five yard line and the goal line.
10. When a Team B player recovers a fumble or kick between his five yard line and the goal line.
11. When necessary to mark forward progress when the runner/passer is driven back.
12. When the Team A player attempting to pass is tackled behind his line of scrimmage (QB "sack").
