2-5. Information sur les champs électromagnétiques

Donnéessur le soudage électrique et les effets des champs magnéti- ques basse fréquence sur l’organisme

En parcourant les câbles de soudage, le courant crée des champs élec- tromagnétiques. Les effets potentiels de tels champs restent préoccupants.Cependant, après avoir examiné plus de 500 études qui ont été faites pendant une période de recherche de 17 ans, un comité de spécialistes du National Research Council a conclu : « L ’accumula- tion de preuves n’a pas démontré que l’exposition aux champs magnétiques et aux champs électriques à haute fréquence constitue un risque pour la santé humaine ». Toutefois, les études et l’examen des preuves se poursuivent. En attendant les conclusions finales de la re- cherche, il serait souhaitable de réduire l’exposition aux champs électromagnétiquespendant le soudage ou le coupage.

Afin de réduire les champs électromagnétiquesen milieu de travail, res- pecter les consignes suivantes :

1.Garder les câbles ensemble en les torsadant ou en les fixant avec du ruban adhésif.

2.Mettre tous les câbles du côté opposé à l’opérateur.

3.Ne pas s’enrouler les câbles autour du corps.

4.Garder le poste de soudage et les câbles le plus loin possible de soi.

5.Placer la pince de masse le plus près possible de la zone de soudage.

Consignes relatives aux stimulateurs cardiaques :

Les personnes qui portent un stimulateur cardiaque doivent avant tout consulter leur médecin. Si ce dernier les déclare aptes, il leur est recom- mandé de respecter les consignes ci-dessus.
