HAZARD IDENTIFICATION
There are no recognised hazards associated directly with unused welding consumables prior to welding.
Packaged consumables may be heavy, and should be handled and stored with care. follow manual
handlingregulations.
Wire wound on reels or spools, or supplied in bulk packages can be coiled under tension.
Take care to avoid the wire uncoiling rapidly when released. wear gloves and eye protection.
When using these wires and rods as part of the welding process additional potential hazards are likely. These are:
Electric shock from the welding equipment or electrode. This can be fatal.
Hot metal spatter and heat, which can cause burns to the hand and body, and may cause fire if in contact with
combustible materials.
UV, IR and light radiation from the arc, which can produce `arc eye' and possible eye damage to
unprotected eyes. Wear suitable protective equipment.
Fumes produced from the welding consumable, material being welded, and the arc radiation. These
consist of:
o Particulate fume such as complex metal oxides, fluorides, and silicates from the weld materials
o Gaseous fume such as ozone and nitrogen oxides from the action of arc radiation on the
atmosphere, and carbon monoxide and dioxide from the oxidation of carbon in the components
and from the shielding gas.
Short term inhalation of these fumes and gases may lead to irritation of the nose, throat and eyes.
Long term overexposure or inhalation of high levels of fumes may result in harmful effects to the
respiratory system, central nervous system and lungs.
Local extraction and /or ventilation should be used to ensure that all hazardous ingredients in the
fume are kept below their individual occupational exposure standards in the welder's and other
workers' breathing zones.
NOTE; If welding is performed on plated or coated materials such as galvanised steel, excessive fume may be
produced which contains additional hazardous components, and may result in metal fume fever and other health
effects.

FIRST AID MEASURES
No first aid measures should be required for the unused wire or rod consumables.
During welding:
I n h alation
If breathing is difficult, bring the patient in fresh air; breathe in fresh air deeply.
For skin b urn s
Submerge affected area in cold water until burning sensation ceases and refer for immediate medical attention.
For eye effects s uch as arc eye an d d u st s
Irrigate eye with sterile water, cover with damp dressing and refer for immediate medical attention if irritation
persists.
I ngestion
Ingestion is considered unlikely due to product form. However, if swallowed do not induce vomiting. Seek medical
attention. Advice to doctor: treat symptomatically.
Electric s hock
If necessary resuscitate and seek immediate medical attention.
FIRE PREVENTION
No specific measures required for the welding consumable prior to welding.
During welding:
Welding should not be carried out in the presence of flammable materials, vapours, tanks, cisterns and pipes
and other containers which have held flammable substances unless these have been checked and certified safe.
MEASURES IN CASE OF UNINTENTIONAL RELEASE
No specific actions for welding consumable prior to use.
Welding in proximity to stored or used halogenated solvents may produce toxic and irritant gases. Prohibit welding in
areas where these solvents are used.

HANDLING AND STORAGE (FOR SAFETY)
No special precautions are required for these welding consumables.
Welding wires and rods are dense materials and can give rise to a handling hazard when reels, spools, bulk packs or
multiple packages are lifted or handled incorrectly or with poor lifting posture.
Good practice for handling and storage should be adopted to prevent physical injuries.

Exposure Prevention
Welders should not touch live electrical parts, and should insulate themselves from the work and the ground.
Manufacturer's guidelines for the use of electrical welding machines should be observed at all times.
Welders and co-workers should be educated about the health hazards associated with welding fume, and trained to
keep their heads out of the fume plume.
During welding, fumes and gases will be produced and emitted from the welding process. The content of the fume is
dependent on the welding consumables, shielding gas and base materials being welded. The amount and
concentration of fume generated is dependent on factors such as current, voltage, welding practices and number of
welders in a given area. By following recommended welding practices, fume production can sometimes be
minimised.
For the carbon steel solid wires and rods covered in this Data Sheet, the main constituents of the fume will be iron
and manganese, mainly in the form of complex oxides and silicates. There will also be smaller amounts of other
complex metal oxides and silicates.
Gaseous ozone, nitrogen oxides, carbon monoxide and carbon dioxide are also formed by the effect of the arc on the
atmosphere and the shielding gas. In some cases ozone levels can be high and additional controls may be needed. The
shielding gas used will also affect the fume formation rate, and higher levels of particulate fume will be generated as
the percentage of carbon dioxide and oxygen is increased in the shielding gas.
Typical fume composition data for copper-coated and bare carbon steel wires is given below.

1 Units are in mgm/m3, except when stat ed otherwise
The fume analyses for the carbon steel wires and rods covered by this data sheet, when used for welding clean,
uncoated plain carbon steels, indicate that as long as the 5 mgm/m3 total fume exposure limits are met, fume levels of
the other constituents will generally be below their respective exposure limits. The exceptions are manganese, ozone
and nitrogen dioxide, as these have low exposure limits and additional controls may be required.
The fume levels given above were generated under laboratory conditions when welding clean, plain carbon steel
under the manufacturers recommended welding parameters, and are indicative of reasonably expected fume levels.
Actual fume levels will vary in practice, depending on the welding parameters and other conditions, and may be
higher or lower than those listed above. Additional fume may arise when these wires and rods are used to weld
contaminated base materials, coated or plated steels, other metals and alloys, or when incorrect welding conditions are
used.

The only accurate way to determine the composition and quantity of fumes and gases to which workers areexposed is
to take air samples from inside the welders helmet, if worn, or in the worker's breathing
zones.Individual fume measurements should be made in these cases using recognised sampling and analysis
standards. Based on the results of these measurements, additional fume controls may be required to ensure that all the
fume constituents are controlled below their exposure limits.
Controls
Good general ventilation, and/or local fume extraction at the arc should be used to control the fumes and
gases produced during welding to below their individual recognised exposure limits when measured in the welder's
and co-workers' breathing zone. In addition the ventilation and extraction should also be sufficient to ensure that the
total particulate fume levels are reduced below 5mgm/m3 when measured in the breathing zone.
In confined spaces where ventilation is not adequate, an air fed breathing system should be used. All
precautions for working in confined space should be observed.
Where fume levels exceed the recognised exposure limits, respiratory protection may be required in the form of a
Class P2 (metal fume) respirator.
Personal Protection
Welders and co-workers in the vicinity should wear protective clothing and eye protection appropriate to arc welding
as specified by local standards.
Protecti on of B ody and Skin
Suitable clothes for welding should be worn such as non light reflective fireproof overalls, leather apron,
welding helmet, leather boots spats and gloves.
Protecti on of H ands
Welders should wear suitable hand protection such a welding gloves or gauntlets of a suitable standard. Co-worker
should also wear suitable hand protection against hot metal, sparks and spatter.
E ye Protection
Welders should wear a welding helmet fitted with the appropriate optical welding filter for the operation. Suitable
protective welding screens and goggles should be provided, and used by others working in the same area.

TOXITY DATA
Welding fumes if inhaled can potentially produce several differing health effects caused by the metal containing
particles and the gases produced during the welding process, both of which are present in the `fumes'. The exact
nature of any likely health effect is dependent on the consumable, material being welded, weld process, all of which
affect fume quantity and composition, as well as the use of adequate ventilation, respirators, or breathing equipment
as circumstances require.
Inhalation of the fumes/gases produced during welding may lead to irritation to the nose throat and eyes. The range of
health effects include respiratory effects with symptoms such as asthma, impaired respiratory and lung function,
chronic bronchitis, metal fume fever, pneumoconiosis, possible emphysema and acute pulmonary oedema.
Other potential health effects at elevated levels of exposure include central nervous effects possible lung cancer, bone
disease, skin and fertility effects. Which of these health effects is potentially likely is related to the fume composition,
and this needs to be consulted with the specific toxicity data below to assess the health risk when using any particular
welding process.
Unprotected skin exposed to UV and IR radiation from the welding arc may burn or redden, and UV radiation is
potentially a carcinogen. UV radiation can affect the unprotected eye by producing an acute condition known as `arc
eye'.
Specific effects relevant to major particulate and gaseous fume constituents produced when welding with these wires
and rods.
Iron
The chief component of fume generated by welding carbon steels is iron oxide. Iron oxide is generally
considered a nuisance material and unlikely to cause any significant health effects. The fume particles however
accumulate in the lungs and lead to a benign pneumoconiosis called siderosis.
Manga nese
Manganese compounds are also found in carbon steel welding fumes. Manganese is mainly a systemic chronic toxin,
although exposure to high particulate concentrations can cause some respiratory irritation.
Overexposure or inhalation of excessive amounts of manganese has been shown to affect pulmonary function, blood
and may cause irreversible central nervous system damage (manganism) which resembles Parkinsons disease.
Symptoms of manganism include tremors, impaired speech, facial expression changes, slow clumsy movements and
eventually impaired walking. The symptoms are typically not apparent for several years.
Co p per
Copper is one of the main causes of any metal fume fever observed during welding. Metal fume fever is a delayed
respiratory effect produced by inhalation of fume. Symptoms include sweating, chills, fever, muscle aches and high
temperature. These acute symptoms normally alleviate within 24-48 hours.

Ozone an d Nitrogen oxides
These gases are formed due to interactions of the arc with the surrounding air. Both gases can produce eye,
respiratory and lung irritation and also can produce longer term lung effects such as decreased lung capacity, chronic
bronchitis, and emphysema. Of particular concern with both gases is that exposure to high levels (eg due to build up
in confined spaces) can result in acute lung effects such as delayed pulmonary oedema.
Carbo n mo n oxide an d carbon dioxide
Carbon monoxide (CO) is a chemical asphyxiant and its toxicity is due to its affinity for oxygen carrying blood
haemoglobin causing fatigue, weakness, dizziness and eventual unconsciousness and possible death.
Carbon dioxide (CO2) is mainly an asphyxiant but can exert some toxic properties by increasing pulse and heart rate.
These gases are mainly formed through decomposition of some electrodes' components, or from oxidation of any
carbon in the wires and rods, or from the shielding gas.
ECOLOGICAL DATA
The welding process produces particulate fumes and gases which may cause long term adverse effects in the
environment if released directly into the atmosphere. Welding fumes from the arc processes which use the wires and
rods covered by this data sheet can produce carbon dioxide gas, which is dangerous to the ozone layer.
DISPOSAL DATA
Packaging and wire and rod scrap should be disposed of as general waste or recycled. No special precautions are
required for this product.
TRANSPORT INFORMATION
No special requirements are necessary in transporting these products.
