b)   l’utilisation pour le transport de personnes ;
c)   le matériel flottant, le matériel de dragage ou le matériel monté sur un bateau ;
d)   les phénomènes dangereux biologiques et chimiques résultant de la manipulation de denrées alimentaires ou de produits pharmaceutiques ;
e)   la conception de la structure d’appui qui ne fait pas partie du convoyeur ;
f)   les effets du vent ;
g)   les phénomènes dangereux dus à la manutention de produits dangereux spécifiques (par exemple explosifs, matériau irradiant) ;
h)   les phénomènes dangereux résultant du contact ou de l’inhalation de fluides, gaz, brouillards, fumées ou poussières nocifs ;
i)   les phénomènes dangereux biologiques et microbiologiques (virus ou bactéries) ;
j)   les phénomènes dangereux dus à l’utilisation de sources de rayonnement ionisant ;
k)   les convoyeurs équipés d’une bande transporteuse avec une surface autre que du caoutchouc ou un polymère pour le milieu de transport continu ;
l)   les phénomènes dangereux liés à l’intégration de convoyeurs à bande dans d’autres machines.
Les prescriptions de sécurité du présent document s’appliquent aux équipements et systèmes mis sur le marché après sa date de publication.
NOTE   La Directive 2014/34/CE relative aux appareils et systèmes de protection destinés à être utilisés en atmosphères explosibles peut s’appliquer au type de machines ou d’équipements couverts par la présente Norme européenne. Le présent document n’est pas destiné à fournir un moyen de satisfaire aux exigences essentielles de santé et de sécurité de la Directive 2014/34/CE.
