3. Hazards 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 HANDLING REGULATIONS.
Some low levels of dust may be produced during handling. DO NOT BREATHE THE DUST.
When using these electrodes as part of the welding process additional potential hazards are likely:
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:
? Particulate fume such as complex metal oxides, fluorides, and silicates from the weld materials.
? Gaseous fume such as ozone and nitrogen oxides from the action of arc radiation on the
atmosphere, and carbon monoxide and dioxide from the dissociation and reaction of some of
the flux constituents.
? 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.
MSDS No. CE 003 ?CAST IRON ELECTRODES ?Rev 0 27.12.04 Page 2 of 8
4. First aid measures
No first aid measures should be required for the unused electrode consumables. During welding:
Inhalation
If breathing is difficult, bring the patient in fresh air; breathe in fresh air deeply.
For skin burns
Submerge affected area in cold water until burning sensation ceases and refer for immediate
medical attention.
For eye effects
For irritation from radiation and dusts, irrigate eye with sterile water, cover with damp dressing and refer
for immediate medical attention if irritation persists.
Ingestion
Ingestion is considered unlikely due to product form. However, if detached flux coating is swallowed do
not induce vomiting. Seek medical attention. Advice to doctor: treat symptomatically.
Electric shock
If necessary resuscitate and seek immediate medical attention.
5. Fire prevention measures
No specific measures required for the welding consumable prior to 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.
6. 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.
7. Handling and storage (for safety)
No special precautions are required for these welding consumables.
Welding electrodes are dense materials and can give rise to a handling hazard when multiple packages
of the electrodes are lifted or handled incorrectly or with poor lifting posture.
Good practice for handling and storage should be adopted to prevent physical injuries.
8. Exposure prevention / Controls / Personal protection
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 electrode type and base material 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 cast iron electrodes, the main constituents of the fume will be iron, copper, nickel, manganese,
sodium, potassium and calcium oxides, fluorides and silicates, mainly in the form of complex oxides and
other compounds. There will also be smaller amounts of other complex metal oxides and silicates.
MSDS No. CE 003 ?CAST IRON ELECTRODES ?Rev 0 27.12.04 Page 3 of 8
Gaseous ozone and nitrous oxides are also formed by arc radiation, and carbon monoxide and carbon
dioxide can also be present due to dissociation and reaction with the atmosphere of some of the flux
constituents.
Fume composition data for some common cast iron electrodes are given below, and the individual
exposure limits for the constituents (when specified) are also given.
Fume exposure should be controlled to below the recognised exposure limit for each of the individual
constituents, and to below 5 mgm/m3 for the total particulate fume.

The fume analyses for the cast iron electrodes covered by this data sheet, when used for welding clean,
3
uncoated unalloyed cast irons, indicate that as long as the 5 mgm/m total fume exposure limits are met,
the fume levels of the other constituents will generally be below their respective exposure limits.
The exceptions are manganese, copper and nickel, as these have low exposure limits, and additional
controls to their individual limits may be required.
MSDS No. CE 003 ?CAST IRON ELECTRODES ?Rev 0 27.12.04 Page 4 of 8
THE FUME LEVELS GIVEN ABOVE WERE GENERATED UNDER LABORATORY CONDITIONS
WHEN WELDING CLEAN, UNALLOYED CAST IRONS 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 electrodes 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 ARE EXPOSED 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. Refer to:
Safe work in confined spaces Free HSE leaflet INDG258 HSE Books 1999. Also available in priced
packs ISBN 0 7176 1442 5.
Safe work in confined spaces: Approved code of practice, r e g u l a t i o n s
and guidance L101 HSE Books 1997 ISBN 0 7176 1405 0.
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.
Protection of Body 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
Protection of Hands
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.
Eye 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.

10. Stability and reactivity
There are no stability or reactivity hazards from electrodes as supplied.
Hazardous decomposition products such as metal oxide fumes and gases (see Section 8) are produced
during welding.
11. Toxicity 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 electrodes
Iron
One of the main components of fume generated by the normal use of cast iron electrodes 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.
Manganese
Manganese compounds are also found in cast iron electrode 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.
Fluorides
The main source of fluorides is from the flux coatings on some cast iron welding electrodes, and this
produces mainly fluoride particulate fume. Fluorides are respiratory irritants and if absorbed through
inhalation can lead to bone disease known as fluorosis.
Silica
Silica is found in welding fumes produced by fluxes and flux coatings and is produced mainly as amorphous silica. This
form of silica has not been associated to any significant degree with lung pneumoconiosis which is associated with
crystalline forms of silica.
MSDS No. CE 003 ?CAST IRON ELECTRODES ?Rev 0 27.12.04 Page 6 of 8
Rutile sand
Mainly present as Titanium dioxide which is a respiratory irritant but in effect mainly a nuisance material
of low toxicity.
Nickel
Nickel is one of the main fume constituents found in cast iron electrode fume. The main health effects of nickel are skin
dermatitis (nickel `itch') and it being classified as a potential human lung carcinogen. It may also cause nasal cancer.
Copper
Copper is one of the main causes of metal fume fever observed in welding. Metal fume fever is a
delayed respiratory effect produced by the inhalation of fume. Symptoms include sweating, chills, fever,
muscle aches, and high temperature. These acute symptoms normally alleviate within 24-48 hours
Ozone and Nitrogen oxides.
These gases are formed due to interactions of the arc with the surrounding air of the welding arc .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.
Carbon monoxide and 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, and by the reaction of graphite in the coatings with oxygen in the atmosphere.
12. 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 electrodes covered
by this data sheet can produce carbon dioxide gas, which is dangerous to the ozone layer.
13. Disposal data
Packaging, stub ends and slag residue should be disposed of as general waste or recycled. No special
precautions are required for this product.
14. Transport information
No special requirements are necessary in transporting these products
