Poison Prevention Packaging Standards.
To protect children from serious personal injury or serious illness resulting  from handling, using, or ingesting household substances, the Commission has  determined that packaging designed and constructed to meet the following  standards shall be regarded as
‘‘special packaging’’ 
(a) General  requirements. The special packaging must continue to function with the  effectiveness specifications set forth in paragraph (b) of this section when in  actual contact with the substance contained therein. This requirement may be  satisfied by appropriate scientific evaluation of the compatibility of the  substance with the special packaging to determine that the chemical and physical  characteristics of the substance will not compromise
or interfere with the  proper functioning of the special packaging.
The special packaging must also  continue to function with the effectiveness specifications set forth in  paragraph (b) of this section for the number of openings and closings customary  for its size and contents. This requirement may be satisfied by appropriate  technical evaluation
based on physical wear and stress factors, force  required for activation, and other such relevant factors which establish that,  for the duration of normal use, the effectiveness specifications
of the  packaging would not be expected to lessen.
Special packaging, tested by the method described in § 1700.20, shall meet  the following specifications:
(1) Child-resistant effectiveness of not less  than 85 percent without a demonstration
and not less than 80 percent after a  demonstration of the proper means of opening such special packaging. In the case  of unit packaging, child-resistant effectiveness of not less than 80  percent.
(2) Ease of adult opening. (i) Senior- adult test shall have a  senior
adult use effectiveness of not less than 90% for the senior-adult  panel test.
