3.2.
Provider and operator duties
The provider may allow the work with the source only to the persons, who are
informed about the safety regulations, trained in the source manipulation and
informed about the source operating instructions.
The person authorized to work with the source is obligated to follow all basic
regulations about safety of operation, with special regard to warnings given in these
operating instructions.
3.3.
Personal protective outfit
The source operator must have strong working shoes, which also insulate in wet
environment, protective working gloves, shield with protective filter for eyes
protection, suitable hardly flammable clothes and aural protectors at increased noise
level.
When other persons are in the source vicinity, they must be instructed about possible
danger, have the protective equipment available, possibly they must be protected
with protective curtains or screens.
When some animals move within the reach of the welding workplace, it is necessary
to adopt measures for their protection, the animals must be prevented from access to
the welding workplace.
3.4. Risks resulting from the action of harmful vapours and gases
The smoke and harmful vapours occurring during the welding are deleterious. It is
necessary to exhaust them using suitable equipment and at the same time it is
necessary to ensure sufficient supply of fresh air.
3.5. Risks resulting from flying off sparks
It is necessary to remove all flammable objects from the source working area.
Volatile, flammable matters, whose vapours are easily inflammable, are especially
dangerous.
No welding works can be carried out in the area serving for storage of gases, fuel,
oils and similar matters, because also the remains of these matters represent
explosion and fire risk.
Special regulations apply in area with fire and explosion risk – therefore their
consistent following is necessary.
3.6.
Other necessary measures
Welding sources are generally in the term of interference voltage designated for work
in the industrial area. When it is used in the living space, special measures are
necessary for elimination of the interference. Therefore the user is obligated to
evaluate whether he cannot cause electromagnetic problems in vicinity at the source
installation. In the first place it is necessary to consider aspect of signal and
telecommunication leads, radio and television receivers and transmitters, computers,
