3) 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 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 of some flux constituents during welding.
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 fumeare
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.

MEASURES IN CASE OF UNITENTIONAL 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)
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
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 carbon steel electrodes, the main constituents of the fume will be iron, 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.
Gaseous ozone and nitrous oxides are also formed by arc radiation, and carbon monoxide and carbon dioxide
can also be present due to dissociation of some of the flux constituents.
Fume Composition data for the major carbon steel 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 carbon steel electrodes covered by this data sheet, and 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.

An exception is manganese, as this has a low exposure limit, and additional controls to this limit 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 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.
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.
Coworker
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.

11) TOXICITY DATA
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
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.
Mangnanese
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.
Fluorides
The main source of fluorides is from the flux coatings on some welding electrodes such as basic types (E7016,
7018, 7028), and this produces mainly fluoride particulate fume. Fluorides are respiratory irritants and if
absorbed through inhalation can lead to bone disease known as fluorosis.

Material Safety Data Sheet
Printing date : December 18, 2006 Reviewing on December 18, 2009 CE001
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.
Rutile sand
Mainly present as Titanium dioxide which is a respiratory irritant but in effect mainly a nuisance material of
low toxicity.
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 (cellulose
and carbonates).
12) ECOLOGICAL DATA
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 basic electrodes covered by this data
sheet can produce carbon dioxide gas, which is dangerous to the ozone layer.
