Welding Health


Published on

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!

Welding Health

  1. 1. Good Safety and Health in Workshops is Good Business 1 2009-06-29
  2. 2. Nederman has been in the environmental business since 1944 • Nederman - founded in 1944 • Certified manufacturing - ISO 9001 and ISO 14000 • Production and assembly facilities in Sweden, Norway, Canada and China • Own sales organisations in 24 countries • Agents and distributors in around 30 countries • Around 600 employees • Welding is a Nederman core segment since the 50´s 2 2009-06-29
  3. 3. Experience from a broad range of industries and applications Machining Metal Fabrication incl Welding Industrial Cleaning Chemical/ Pharmaceutical/ Labs Heavy Vehicle Repair Shops Shipping, yards, offshore Composite Manufacture Emergency Stations 3 2009-06-29
  4. 4. Focus on clean and safe working areas • Increased awareness (industry as well individuals) of the environment and health risks and associated costs • Stricter directives and laws • Increased focus on production efficiency • Large interest for energy saving solutions 4 2009-06-29
  5. 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. 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 *European Agency for Safety and Health at Work (set up by EU 1996) 6 2009-06-29
  7. 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 WELDING WITHOUT PROTECTION AIRBORNE PARTICLES FROM 2 WEEKS WELDING 7 2009-06-29
  8. 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 8 2009-06-29
  9. 9. Sizes of welding fume/gas particles Welding fume 9 2009-06-29
  10. 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 10 2009-06-29
  11. 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 11 2009-06-29
  12. 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 Nickel 0.5 1.0 0.1 0.5 0.5 0.1 12 2009-06-29
  13. 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. • Based on this measurement being able to indicate if they are below or above legislative occupational exposure limits. 13 2009-06-29
  14. 14. Clean air should be a basic Human Right • We breathe 80-100 litres of air per minute = 4800 litres per hour! • With moderate work or exercise we breathe twice that amount. 14 2009-06-29
