(1) from fracture, fragmentation, or disassembly of the article;
(2) from propulsion of the article (or a part or accessory thereof);
(3) from points or other protrusions, surfaces, edges, openings, or closures;
(4) from moving parts;
(5) from lack or insufficiency of controls to reduce or stop motion;
(6) as a result of self-adhering characteristics of the article;
(7) because the article (or a part or accessory thereof) may be aspirated or ingested;
