The closures of drug and chemical vials are safe from misuse by children if the locking power or seals has to exceed the manual traction and torsion power of a child-s hand and if the sealing device has to provide for trigger-points in distances large enough to exceed the spread of a child-s hands. The authors have conducted tests in 2-12 children to establish their manual traction and torsion power. The results are given in tables. The maximal traction and holding power of children 2-5 years old on knob or disc-shaped handles of 4-30 mm diameter were 1-3,5 Kp and approximate maximum of the angular momentum on handles between 2-68 mm were 20-100 mp.
