Hazard classification according to the criteria of NOHSC.
Dangerous goods classification according to the Australia Dangerous Goods
Code.
Risk Phrase Not classified as hazardous
(s)
Methods of Exposures to welding fume and gases can be highly variable depending on the
Exposure position of the welder and workpiece, the air speed and direction and conditions
of confinment. However if adequate ventilation is provided, then the total fume
exposure during welding will be significantly below the 5 mg/m3 NOHSC
exposure standard for welding fume. Test results suggest that other components
of the fume and gases would be well below their respective exposure standards
in this case.
Other FROM HEAT GENERATED FUME ONLY: With burning or welding, moderate
Information amounts
of fume are emitted which contain mostly visible finely divided zinc oxide (ZnO)
and iron oxide (Fe2O3) fume. Fume flocculates as it ages. Small amounts of
ozone and other gases may be emitted.

Specific
Hazards None under normal storage conditions.
6. ACCIDENTAL RELEASE MEASURES
Spills &
Disposal Non-hazardous.
7. HANDLING AND STORAGE
Additional
information
on
precautions Welding tests done on Galvanized Tubeline Pipe showed levels of particulate
for use fume and ozone gas emission comparable to other galvanized steel tube.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
National 5.0 mg/m3 as welding fume particulate - Time Weighted Average
Exposure 5.0 mg (Fe)/m3 as Iron Oxide fume - Time Weighted Average
Standards 0.1 ppm as ozone gas - Time Weighted Average
0.1 ppm as ozone gas - Short Term Exposure Limit.
1 mg/m3 as manganese fume - Time Weighted Average.
3 mg/m3 as manganese fume - Short Term Exposure Limit.
5 mg/m3 as zinc oxide fume - Time weighted average.
10 mg/m3 as zinc oxide fume - Short term exposure limit.
0.05 mg/m3 as Cr VI - Time weighted average
Engineering Ventilation recommended if welding or flame cutting.
Controls Refer to WTIA Technical Note 7, and WTIA fume minimisation guidelines.
Personal If exposed to fumes from welding or hot cutting of galvanized hollow sections
Protective because of poor ventilation, wear a dust filter respirator approved for
Equipment welding fume. Continuous welding in confined space should only be done
wearing an air-line respirator.

etc.
10. STABILITY AND REACTIVITY
11. TOXICOLOGICAL INFORMATION
Inhalation Dust from cleaning & grinding operations,particulate fume, ozone and other
gases from flame cutting and welding may be respiratory irritants but
are not normally a problem if exposure is kept to below the standard.
Metal fume fever, 'zinc chills' may result from inhalation of fumes from welding
or flame cutting galvanized pipe. Symptoms of zinc chills manifest themselves
within 8 hours. They begin with a metallic taste in mouth followed by coughing,
chills, weakness, fatigue, and a general malaise/ fever similar to that for
influenza.
Complete recovery occurs within about 24 hours. A partial immunity may
develop with continuous exposure.
Ingestion Not normally a hazard due to the physical form of product
Skin Sharp burrs on the edges of steel products can cause lacerations to unprotected
skin. Burns may result from contact with hot surfaces.
Eye Cutting, grinding, hand tool cleaning, etc. operations may generate (hot) metal
particles which are potentially injurious to eye tissue.
Chronic Chronic exposure to iron oxide fumes over the standard may lead to Siderosis
Effects which is a benign lung condition.
Chronic exposure to manganese fumes over the standard may lead to disorders
of the nervous and reproductive systems.
Metal Fume Fever or 'zinc chills' is a self-limiting acute illness. No chronic effects
are known.
