would include carbon oxides, nitrogen oxides and ozone. Air contaminants around the welding area can be affected by the
welding process and influence the composition and quality of fumes and gases produced.

11. TOXICOLOGICAL INFORMATION:
Signs and Symptoms of Overexposure: Inhalation of welding fumes and gases can be dangerous to your health.
Classification of welding fumes is difficult because of varying base materials, coatings, air contaminants and processes. The
Internal Agency for Research on Cancer has classified welding fumes as possible carcinogenic to humans (Group 2B).
Acute Effects: Overexposure to welding fumes may result in symptoms like metal fume fever, dizziness, nausea, dryness or
irritation of the nose, throat or eyes. May cause sensitisation by skin contact

Chronic Effects: Overexposure to welding fumes may affect pulmonary function. Overexposure to manganese and
manganese compounds above safe exposure limits can cause irreversible damage to the central nervous system, including the
brain, symptoms of which may include slurred speech, lethargy, tremor, muscular weakness, psychological disturbances and
spastic gait.

12. ECOLOGICAL INFORMATION:
Toxicity: Welding rods contain metals which are considered to be very toxic towards aquatic organisms. Finely divided
welding rods are therefore considered harmful to aquatic organisms.
Persistence and Degradability: The welding rods consist of elements that can not degrade any further in the environment.
Bio accumulative Potential: Welding rods contain heavy metals which bio accumulates in the food chain. The following
figures are the bio concentration factor (BCF) for the substances on their own.
BCF:
Iron, BCF: 140000
Manganese, BCF: 59052
Mobility in Soil: Welding rods are not soluble in water or soil. Particles formed by working welding rods can be transported in
the air.
Other Adverse Effects: In massive form, welding rods present no hazards to the aquatic environment.
Welding materials could degrade into components originating from the materials used in the welding process. Avoid exposure to
conditions that could lead to accumulation in soils or groundwater. Harmful to aquatic organisms, may cause long-term adverse
effects in the aquatic environment.

13. DISPOSAL CONSIDERATIONS:
Product: For product elimination, consult recycling companies or appropriate local authority.
USA RCRA: Unused products or product residue containing chromium is considered hazardous waste if discarded, RCRA ID
Characteristics Toxic Hazardous Waste D007. Residue from welding consumables and processes could degrade and
accumulate in soils and groundwater.
Package: May be disposed in approved landfills provided local regulations are observed.
