SAFETY AND HANDLING
4
To prevent possible injury caused by incorrect handling of the raw materials and solvents
used in the process, carefully read the Material Safety Data Sheet (MSDS) provided by
your supplier.
Deal with waste caused according to current regulations.
Pour éviter toute blessure causée par une mauvaise manipulation des matières
premières et les solvants utilisés dans le processus, veuillez lire attentivement la fiche
signalétique (MSDS) fournies par votre fournisseur.
To avoid damage caused by the impact of pressurized fluids, do not open any connection
or perform maintenance work on the components subject to pressure until the pressure
has been completely eliminated.
Pour éviter les dommages causés par l'impact des fluides sous pression, ne pas ouvrir
un lien ou d'effectuer des travaux d'entretien sur les éléments soumis à la pression jusqu'à
ce que la pression a été complètement éliminé.
Use suitable protection when operating, maintaining or being present in the area where
the equipment is functioning. This includes, but is not limited to, the use of protective
goggles, gloves, shoes and safety clothing and breathing equipment.
Utiliser une protection appropriée utilisation, d'entretien ou d'être présents dans la région
où le matériel fonctionne. Cela inclut, mais n'est pas limité à, l'utilisation de lunettes de
protection, gants, chaussures et vêtements de sécurité et un équipement respiratoire.
The equipment includes components that reach high temperatures and can cause burns.
Hot parts of the equipment must NOT be handled or touched until they have cooled
completely.
L'équipement comprend des éléments qui atteignent des températures élevées et
peuvent provoquer des brûlures. Les parties chaudes de l'équipement ne doit pas être
manipulé ou touché jusqu'à ce qu'ils aient complètement refroidi.
To prevent serious injury through crushing or amputation, do not work with the equipment
without the safety guards installed on the moving parts. Make sure that all the safety
guards are correctly reinstalled at the end of the repair or maintenance work of the
equipment.
L'équipement comprend des éléments qui atteignent des températures élevées et
peuvent provoquer des brûlures. Les parties chaudes de l'équipement ne doit pas être
manipulé ou touché jusqu'à ce qu'ils aient complètement refroidi.
