Snap-Lock Beads Danger Analysis


 A tragic accident occurred when a 16 month old child fell face down and an oblong plastic toy snap-lock bead lodged in his throat obstructing his airway. Approaches utilized in the danger analysis include safety and medical literature review, codes and standards research, accident statistics survey, and evaluation of alternative snap-lock beads designs. Results of the danger analysis indicate that there are technically and economically feasible design alternatives which prevent the snap-lock beads from blocking the user’s airway.
