Basic Welding Health Hazards

Welding joins two metal pieces by the use of heat and with or without pressure apply.

Common Welding Processes are:

Health threats by Gases & Fumes

 

Mainly gases and fumes come from different way:

  • Base material and filler material
  • Coating and paints
  • Shielding gases and their chemical reactions
  • Process and different types of consumable used
  • Contaminants in the atmosphere
  • Wrong welding techniques

Health Hazards:

Contact of welding gases and fumes may have Short time impact and Long time impact.

Short time Hazards

  • Irritate the eyes, nose, chest and respiratory tract.
  • Cause coughing, wheezing, shortness of breath, bronchitis, pulmonary edema, and pneumonitis .
  • Cause nausea, loss of appetite, vomiting, cramps,  and slow digestion.

Long Time Hazards

?  Welders may chance a variety of chronic lung problems, including: Bronchitis, asthma, pneumonia, emphysema, pneumoconiosis, decreased lung capacity, silicosis, and siderosis.

 

Other Health Hazards:

1.       Heat exposure

  • Skin burns and skin cancer

2.       Noise

  • May also increased metal  stress & blood pressure, and  further cause to heart problems, exhaustion, nervousness, and bad temper.

3.  Eye damage– More than 5% eye injuries in industries and construction are associated with welding and cutting

  • damage to retina
  • damage to cornea, resulting in cataracts
  • permanent eye damage
