18、, (c) BSI DRAFT BS 7272-2:2007 3 Foreword This British Standard is published by the British Standards Institution (BSI) and comes into effect on XX Month 200X. If a child inhales an end closure it may become lodged below the larynx and so block the trachea. The risk of asphyxiation can be reduced if
19、 the end closure is securely attached, ventilated, flush with or protrudes only a minimal amount from the end of the writing instrument or is too large to enter the airway. Children should be actively discouraged from sucking, chewing or putting pens in their mouths. If end closures are essential, t
20、he provisions of this British Standard minimize risk by specifying the design and/or the security of attachment, which reduces the likelihood of inhalation and delays asphyxiation pending medical intervention. The Technical Committee recognizes that whilst it is possible to identify the age range of
21、 the children who are most at risk, it is not possible to identify with certainty any writing instruments with end closures that would never be accessible to children and hence never pose a risk. It is, however, acknowledged that certain products are not intended for use by children and such items s
22、hould be clearly labelled to that effect. A British Standard does not purport to include all the necessary provisions 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.
