Health problems affect production. The result is reduced capacity and reoccurring disturbances, eventually decreased profit. Furthermore, not only welders are at risk in unsafe environments. Production equipment, as well as end products, are negatively affected from the lack of adequate safety measures. Automated welding equipment such as robots - and its operators - can be subject to residual fumes and also need to be protected. Good safety and health is good business!

5. Work is a significant part
in the lives of most Europeans
• 730,000 welders
• 5.5 million welding related jobs
• 160 sick-leave working hours per welder
• Every 3,5 minute somebody in the EU dies
from work-related causes = 150,000 a year
• Work related accidents 8,900
• Occupational diseases 142,000
Survey every five years of all Europeans
28% of workers suffer from non-accidental health problems
35% of workers feel their job is a health risk
5 2009-06-29

6. EU-OSHA* collect, analyse
and spread environmental information
Objectives
Reduce the total incidence rate by 25% of accidents at work per
100 000 workers in the EU 27 for the period 2007-2012.
How?
• Guarantee the proper implementation of EU legislation
• Support the implementation
• Adapt the legal framework to changes in the workplace
• Promote development/implementation of national strategies
• Encourage changes in the behaviour of workers and their
employers to adopt health focused approaches
• Evaluate new potential risks
• Promote health and safety at international level

7. Welding fume - huge problem
causing many serious threats to health and safety
One single welder produces 20 - 40 g welding fume per hour = 35-70 kg per year

8. Content of Welding fumes and gases
and their potential health effects
Fumes Source Health effects & symptoms
Chromium (VI) Welding processes. Stainless steel, Skin irritation, respiratory tract irritation, effects on nose, eyes and ears; chronic
plating, chromium pigment manufacturing, effects include lung cancer, kidney and liver damage
electrode
Iron oxide Welding processes: All iron or steel Acute effects are nose and lung irritation; siderosis (pulmonary deposition of
iron dust)
Manganese Welding processes, high-tensile steel Chemical pneumonitis; chronic effects include nervous system disorders
Nickel Welding processes: Stainless steel, Dermatitis, asthma-like lung disease; chronic effects include cancer (nose,
nickel-clad steel, plating larynx, lung), respiratory tract irritation, renal dysfunction
Fluorides Electrode coating, flux material Eye, nose and throat irritation, gastro-intestinal symptoms; chronic effects
include bone and joint problems, fluid in the lungs, kidney dysfunction
Ozone Formed in the welding arc Acute effects include fluid in the lungs and haemorrhage; chronic effects
include changes in lung function
Nitrogen oxide Formed in the welding arc Pneumonitis, pulmonary edema; chronic bronchitis, emphysema; pulmonary
fibrosis
Carbon Carbon dioxide shielded metal-arc Headache, nausea, dizziness, collapse, death; chronnic cardiovascular effects
monoxide welding, electrode coatings

9. Sizes of welding fume/gas particles
Welding fume

10. Body´s defence mechanism:
99% of all particles reach the lungs!
In our respiratory system, particle sizes:
•10 – 2 µm are separated in the throat
•2 – 0.5 µm are separated in the windpipe
•<0.5 µm reaches all the way to the lungs
•Particles <5 µm are the “respirable part” as they may
enter into the lungs

11. How do pollutions harm the human body?
Pollutions affect:
The brain: The skin:
DDT, Carbon oxides PCB
Metallic quicksillver
Organic quicksilver
The blood:
Lead
The lungs:
Manganese, Zink, Copper
Asbestos, Cadmium The kidneys:
Nox (hydrocarbons) Lead, cadmium
Sulfur dioxide remains from quicksilver
The liver: Nerves in arms and legs:
DDT Lead

12. Exposure limits of welding fumes containing
Cr, Mn or Ni during a 8 hour period
(mg/m3)
Czech Rep USA Sweden Germany France UK
Cr (VI) 0.05 0.005 0.005 0.05 0.05 0.05
Manganese 1.0 0.2 0.1 0.5 0.5 0.5

13. Measuring dust concentration in our
customers workshops.
• Nederman is offering “consulting services” by
reviewing our customers extraction systems (both
Nederman and competitor installations).
• Using a DustTrak for measuring dust
concentrations in our customers workshops.
