10.6 Hazardous decomposition products
When this product is used in a welding process, hazardous decomposition product would include those from
volatilization, reaction or oxidation of the material listed in section 3 and those from the base metal and coating.
The amount of fumes generated from this product varies with welding parameters and dimensions. Refer to
applicable national exposure limits for fume compounds, including those exposure limits for fume compounds
found in section 3. Reasonably expected gaseous products 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.
SECTION 11: Toxicological information
Information on toxicological effects
Acute toxicity
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.
LD/LC50 Values that are relevant for classification
Aluminum 7429-90-5 Oral LD50 >15900 mg/kg (rat) Inhalation LC50 >.888 mg/L/4 hr. (rat) LC50 12 mg/l (96h)
(rainbow trout)
Silicon 7440-21-3 Oral LD50 3160 mg/kg (rat)
Respiratory or skin sensitization
Overexposure to welding fumes may affect pulmonary function.
Carcinogenicity
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).
STOT-repeated exposure
Overexposure to welding fumes may affect pulmonary function.
SECTION 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
