18、s British Standard is published by the British Standards Institution (BSI) and comes into effect on XX Month 200X. If a child inhales a pen cap it may become lodged below the larynx and so block the trachea. The risk of asphyxiation can be reduced if the pen cap is ventilated or too large to enter t
19、he airway. Children should be actively discouraged from sucking, chewing or putting pen caps in their mouths If caps are essential the provisions of this British Standard minimize risk by specifying the design and performance of ventilated caps which reduce the likelihood of inhalation and delays as
20、phyxiation pending medical intervention. The Technical Committee recognizes that whilst 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
21、 and hence never pose a risk. It is, however, acknowledged that certain products are not intended for use by children and such items should be clearly labelled to that effect. This British Standard is technically related to ISO 11540 A British Standard does not purport to include all the necessary p
22、rovisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
