Introduction
If a child inhales a pen cap it might become lodged below the larynx and block the trachea. The risk of
asphyxiation can be reduced if the pen cap is ventilated or too large to enter the airway. Children must
be actively discouraged from sucking, chewing or putting pen caps in their mouths. A way of avoiding
the risk of inhalation of caps of writing and marking instruments is to manufacture products without
caps whenever possible. However, if caps are essential, the provisions of this document minimize risk
by specifying the design and performance of ventilated caps, which reduce the likelihood of inhalation
and delay asphyxiation pending medical intervention.

ISO/TC 10 recognizes that while it is possible to identify the age range of the children who are most
at risk, it is not possible to identify with certainty any writing instruments with detachable caps that
would never be accessible to children and hence never pose a risk. It is, however, acknowledged that
