1-5. EMF Information
Electric current flowing through any conductor causes localized electric
and magnetic fields (EMF). The current from arc welding (and allied pro-
cesses including spot welding, gouging, plasma arc cutting, and induc-
tion heating operations) creates an EMF field around the welding circuit.
EMF fields can interfere with some medical implants, e.g. pacemakers.
Protective measures for persons wearing medical implants have to be
taken. For example, restrict access for passersby or conduct individu-
al risk assessment for welders. All welders should use the following pro-
cedures in order to minimize exposure to EMF fields from the welding
circuit:
1. Keep cables close together by twisting or taping them, or using a
cable cover.
2. Do not place your body between welding cables. Arrange cables
to one side and away from the operator.
3. Do not coil or drape cables around your body.
4. Keep head and trunk as far away from the equipment in the
welding circuit as possible.
5. Connect work clamp to workpiece as close to the weld as
possible.
6. Do not work next to, sit or lean on the welding power source.
7. Do not weld whilst carrying the welding power source or wire
feeder.
About Implanted Medical Devices:
Implanted Medical Device wearers should consult their doctor and the
device manufacturer before performing or going near arc welding, spot
welding, gouging, plasma arc cutting, or induction heating operations.
If cleared by your doctor, then following the above procedures is recom-
mended.

2-5. Informations relatives aux CEM
Le courant électrique qui traverse tout conducteur génère des champs
électromagnétiques (CEM) à certains endroits. Le courant de soudage
crée un CEM autour du circuit et du matériel de soudage. Le courant
issu d’un soudage à l’arc (et de procédés connexes, y compris le
soudage par points, le gougeage, le découpage plasma et les
opérations
de chauffage par induction) crée un champ
électromagnétique
(CEM) autour du circuit de soudage. Les champs
électromagnétiques
produits peuvent causer interférence à certains
implants médicaux, p. ex. les stimulateurs cardiaques. Des mesures de
protection pour les porteurs d’implants médicaux doivent être prises:
Limiter par exemple tout accès aux passants ou procéder à une
évaluation
des risques individuels pour les soudeurs. Tous les
soudeurs doivent appliquer les procédures suivantes pour minimiser
l’exposition aux CEM provenant du circuit de soudage:
1 Rassembler les câbles en les torsadant ou en les attachant avec
du ruban adhésif ou avec une housse.
2 Ne pas se tenir au milieu des câbles de soudage. Disposer les
câbles d’un côté et à distance de l’opérateur.
3 Ne pas courber et ne pas entourer les câbles autour de votre
corps.
4 Maintenir la tête et le torse aussi loin que possible du matériel du
circuit de soudage.
5 Connecter la pince sur la pièce aussi près que possible de la
soudure.
6 Ne pas travailler à proximité d’une source de soudage, ni
s’asseoir ou se pencher dessus.
7 Ne pas souder tout en portant la source de soudage ou le
dévidoir.
En ce qui concerne les implants médicaux :
Les porteurs d’implants doivent d’abord consulter leur médecin avant
de s’approcher des opérations de soudage à l’arc, de soudage par
points, de gougeage, du coupage plasma ou de chauffage par
induction. Si le médecin approuve, il est recommandé de suivre les pro-
cédures précédentes.
