The significant and specific hazards are listed in clause 4 and are dealt with in this standard.
This standard does not cover completely the hazards arising from the use of highly flammable additives, for example pentane used as a blowing agent (see 4.3), because these hazards depend to a large extent on the additives and process used.
This standard does not cover the hazards due to noise generated by the cutting unit, which is the only significant source of noise at such plant.
This standard does not cover the requirements for the design of exhaust systems.
This standard does not cover the hazards arising from the assembly of separate units not supplied at the same time by the same manufacturer.
This standard applies to reaction moulding plant manufactured after the date of publication of this standard.
NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.

Machines pour les matières plastiques et le caoutchouc - Machines de moulage par réaction - Partie 2: Prescriptions de sécurité relatives aux installations de moulage par réaction
Cette norme spécifie les exigences essentielles d'hygiène et de sécurité relatives à la conception des installations
de moulage par réaction, à l'exception des unités de dosage et de mélange (pour ces dernières, voir la partie 1).
Les phénomènes dangereux significatifs et spécifiques sont énumérés à l'article 4 et sont traités dans cette norme.
Cette norme ne couvre pas complètement les phénomènes dangereux provenant de l'utilisation d'additifs
facilement inflammables, par exemple le pentane utilisé comme agent d'expansion (voir 4.3), car ces phénomènes
dépendent principalement des additifs et du procédé utilisés.
Cette norme ne couvre pas les phénomènes dangereux résultant du bruit émis par l'unité de coupe, qui est la seule
source de bruit significative sur ce type d'installation.
Cette norme n'énonce pas d'exigences relatives à la conception des systèmes d'aspiration.
Cette norme ne couvre pas les phénomènes dangereux résultant de l'assemblage de parties constitutives
distinctes n'ayant pas été livrées simultanément par le même fabricant.
Cette norme s'applique aux installations de moulage par réaction fabriquées après la date de publication de
cette norme.
NOTE La Directive 94/9/CE relative aux appareils et systèmes de protection destinés à être utilisés en atmosphères
explosibles peut être appliquée au type de machine ou équipement couvert par cette norme européenne. La présente norme
n'est pas destinée à fournir un moyen de satisfaire aux exigences essentielles de Santé et de Sécurité de la Directive
94/9/CE.
