2.2 Release of gasses, vapours, suspended matter or particles
1. Fume extraction for welding is available and is used.
2. No tungsten welding electrodes containing thorium oxide are used.
3. In order to avoid the formation of unnecessarily high amounts of welding fumes, the most suitable parameters are chosen for the respective processes:
- Autogenous technology: small torch size, limited consumption of oxygen, small flame length,
- Arc welding: Low welding voltage, low welding current, small arc length,
- MAG/MIG welding: low welding voltage, low welding current strength, higher percentage of noble gasses (e.g., argon), low shielding gas flow rate.

7. Occupational medical health examinations are arranged when activities involve wearing:
- filter units with particle filters belonging to Classes P1 and P2 and particle filtering half masks, if these are worn for more than 30 minutes per day,
- filter respirators with Class P3 particle filters, gas filters or combination filters.
2.3 Handling of hazardous substances, e.g., cooling lubricant, thinner
1. Protective shields against the splashing of cooling lubricants are available and are used.
