Information sur les champs electromagnetiques Donnees sur le soudage electrique et les effets des champs magnetiques basse frequence sur l’organisme En parcourant les cables de soudage, le courant cree des champs electromagnetiques. Les effets potentiels de tels champs restent preoccupants. Cependant, apres avoir examine plus de 500 etudes qui ont ete faites pendant une periode de recherche de 17 ans, un comite de specialistes du National Research Council a conclu : « L’accumulation de preuves n’a pas demontre que l’exposition aux champs magnetiques et aux champs electriques a haute frequence constitue un risque pour la sante humaine ». Toutefois, les etudes et l’examen des preuves se poursuivent. En attendant les conclusions finales de la recherche, il serait souhaitable de reduire l’exposition aux champs electromagnetiques pendant le soudage ou le coupage. Afin de reduire les champs electromagnetiques en milieu de travail, respecter les consignes suivantes : 1. Garder les cables ensemble en les torsadant ou en les fixant avec du ruban adhesif. 2. Mettre tous les cables du cote oppose a l’operateur. 3. Ne pas s’enrouler les cables autour du corps. 4. Garder le poste de soudage et les cables le plus loin possible de soi. 5. Placer la pince de masse le plus pres possible de la zone de soudage. Consignes relatives aux stimulateurs cardiaques : Les personnes qui portent un stimulateur cardiaque doivent avant tout consulter leur medecin. Si ce dernier les declare aptes, il leur est recommande de respecter les consignes ci-dessus. OM-945 Page 8 SECTION 3 . DEFINITIONS 3-1.
