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,
