Physical and Chemical Hazard
Solid.

Toxic smoke/fumes in a fire.
Dispose of this material and its container at hazardous or special waste collection point.
Health Hazards
Inhaled
Ingestion
Skin Contact
The material is not thought to produce adverse health effects or irritation of the respiratory tract (as classified by EC Directives using animal
models). Nevertheless, good hygiene practice requires that exposure be kept to a minimum and that suitable control measures be used in an
occupational setting.
Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability
if excessive concentrations of particulate are inhaled.
If prior damage to the circulatory or nervous systems has occurred or if kidney damage has been sustained, proper screenings should be
conducted on individuals who may be exposed to further risk if handling and use of the material result
in excessive exposures.
The material has NOT been classified by EC Directives or other classification systems as "harmful by ingestion". This is because of the lack of
corroborating animal or human evidence. The material may still be damaging to the health of the individual, following ingestion, especially where
pre-existing organ (e.g liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses
producing mortality rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and
vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.
Evidence exists, or practical experience predicts, that the material either produces inflammation of the skin in a substantial number of individuals
following direct contact, and/or produces significant inflammation when applied to the healthy intact skin of animals, for up to four hours, such
inflammation being present twenty-four hours or more after the end of the exposure period. Skin irritation may also be present after prolonged or
repeated exposure; this may result in a form of contact dermatitis (nonallergic). The dermatitis is often characterised by skin redness (erythema)
and swelling (oedema) which may progress to blistering (vesiculation), scaling and thickening of the epidermis. At the microscopic level there
may be intercellular oedema of the spongy layer of the skin (spongiosis) and intracellular oedema of the epidermis.
The material may accentuate any pre-existing dermatitis condition
Skin contact is not thought to have harmful health effects (as classified under EC Directives); the material may still produce health damage
following entry through wounds, lesions or abrasions.
Open cuts, abraded or irritated skin should not be exposed to this material

POTASSIUM IODIDE
Entry into the blood-stream through, for example, cuts, abrasions, puncture wounds or lesions, may produce systemic injury with harmful effects.
Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.
Eye
Evidence exists, or practical experience predicts, that the material may cause eye irritation in a substantial number of individuals and/or may
produce significant ocular lesions which are present twenty-four hours or more after instillation into the eye(s) of experimental animals.
Repeated or prolonged eye contact may cause inflammation characterised by temporary redness (similar to windburn) of the conjunctiva
(conjunctivitis); temporary impairment of vision and/or other transient eye damage/ulceration may occur.
Practical evidence shows that inhalation of the material is capable of inducing a sensitisation reaction in a substantial number of individuals at a
greater frequency than would be expected from the response of a normal population.
Pulmonary sensitisation, resulting in hyperactive airway dysfunction and pulmonary allergy may be accompanied by fatigue, malaise and aching.
Significant symptoms of exposure may persist for extended periods, even after exposure ceases. Symptoms can be activated by a variety of
nonspecific environmental stimuli such as automobile exhaust, perfumes and passive smoking.
Practical experience shows that skin contact with the material is capable either of inducing a sensitisation reaction in a substantial number of
individuals, and/or of producing a positive response in experimental animals.
Chronic
Exposure to the material may cause concerns for humans owing to possible developmental toxic effects, generally on the basis that results in
appropriate animal studies provide strong suspicion of developmental toxicity in the absence of signs of marked maternal toxicity, or at around the
same dose levels as other toxic effects but which are not a secondary non-specific consequence of other toxic effects.
Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or
biochemical systems.
Long term exposure to high dust concentrations may cause changes in lung function (i.e. pneumoconiosis) caused by particles less than 0.5
micron penetrating and remaining in the lung. A prime symptom is breathlessness. Lung shadows show on X-ray.
Iodine and iodides, whether applied topically or administered systemically, may produce allergic reactions such as urticaria, angioedema,
cutaneous haemorrhage or purpuras, arthralgia, lymphadenopathy and eosinophilia.
Iodine and iodides may produce goitre and hypothyroidism as well as hyperthyroidism. A mild toxic syndrome resulting from chronic iodide
overdose and from repeated administration of small amounts of iodine ("iodism") is characterised by salivation, coryza, sneezing, conjunctivitis,
headache, fever, laryngitis, bronchitis, stomatitis, parotitis (iodine mumps), and various skin rashes (iododerma*, thrombotic thrombocytopenic
purpura). Swelling and inflammation of the throat, irritated and swollen eyes and pulmonary oedema may also occur. Oedema of the glottis,
necessitating tracheotomy has been reported. Occasional use of iodides for asthma in pregnancy has resulted in foetal death, severe goiter,
hypothyroidism and the cretinoid appearance of the new-born. *Iododerma may vary from mild erythema and acneform eruptions to urticaria and
suppurative or haemorrhagic rashes

MATERIAL DATA
It is the goal of the ACGIH (and other Agencies) to recommend TLVs (or their equivalent) for all substances for which there is evidence of health effects at airborne concentrations encountered in the
workplace.
At this time no TLV has been established, even though this material may produce adverse health effects (as evidenced in animal experiments or clinical experience). Airborne concentrations must be
maintained as low as is practically possible and occupational exposure must be kept to a minimum.
NOTE: The ACGIH occupational exposure standard for Particles Not Otherwise Specified (P.N.O.S) does NOT apply.
Sensory irritants are chemicals that produce temporary and undesirable side-effects on the eyes, nose or throat. Historically occupational exposure standards for these irritants have been based on
observation of workers' responses to various airborne concentrations. Present day expectations require that nearly every individual should be protected against even minor sensory irritation and
exposure standards are established using uncertainty factors or safety factors of 5 to 10 or more. On occasion animal no-observable-effect-levels (NOEL) are used to determine these limits where
human results are unavailable. An additional approach, typically used by the TLV committee (USA) in determining respiratory standards for this group of chemicals, has been to assign ceiling values
(TLV C) to rapidly acting irritants and to assign short-term exposure limits (TLV STELs) when the weight of evidence from irritation, bioaccumulation and other endpoints combine to warrant such a
limit. In contrast the MAK Commission (Germany) uses a five-category system based on intensive odour, local irritation, and elimination half-life. However this system is being replaced to be consistent
with the European Union (EU) Scientific Committee for Occupational Exposure Limits (SCOEL); this is more closely allied to that of the USA.
OSHA (USA) concluded that exposure to sensory irritants can:
cause inflammation
cause increased susceptibility to other irritants and infectious agents
lead to permanent injury or dysfunction
permit greater absorption of hazardous substances and
acclimate the worker to the irritant warning properties of these substances thus increasing the risk of overexposure.
Established occupational exposure limits frequently do not take into consideration reproductive end points that are clearly below the thresholds for other toxic effects. Occupational reproductive
guidelines (ORGs) have been suggested as an additional standard. These have been established after a literature search for the reproductive no-observed-adverse effect-level (NOAEL) and the
lowest-observed-adverse-effect-level (LOAEL). In addition the US EPA's procedures for risk assessment for hazard identification and dose-response assessment as applied by NIOSH were used in
the creation of such limits. Uncertainty factors (UFs) have also been incorporated.
These exposure guidelines have been derived from a screening level of risk assessment and should not be construed as unequivocally safe limits. ORGS represent an 8-hour time-weighted average
unless specified otherwise.

Exposure controls
Engineering controls are used to remove a hazard or place a barrier between the worker and the hazard. Well-designed engineering controls
can be highly effective in protecting workers and will typically be independent of worker interactions to provide this high level of protection.
The basic types of engineering controls are:
Process controls which involve changing the way a job activity or process is done to reduce the risk.
Enclosure and/or isolation of emission source which keeps a selected hazard "physically" away from the worker and ventilation that strategically
"adds" and "removes" air in the work environment. Ventilation can remove or dilute an air contaminant if designed properly. The design of a
ventilation system must match the particular process and chemical or contaminant in use.
Employers may need to use multiple types of controls to prevent employee overexposure.
Local exhaust ventilation usually required. If risk of overexposure exists, wear approved respirator. Correct fit is essential to obtain adequate
protection. Supplied-air type respirator may be required in special circumstances. Correct fit is essential to ensure adequate protection.
An approved self contained breathing apparatus (SCBA) may be required in some situations.
Provide adequate ventilation in warehouse or closed storage area. Air contaminants generated in the workplace possess varying "escape"
velocities which, in turn, determine the "capture velocities" of fresh circulating air required to effectively remove the contaminant.
Appropriate engineering controls
Type of Contaminant:
Air Speed:
solvent, vapours, degreasing etc., evaporating from tank (in still air).
0.25-0.5 m/s
(50-100 f/min.)
aerosols, fumes from pouring operations, intermittent container filling, low speed conveyer transfers, welding, spray
drift, plating acid fumes, pickling (released at low velocity into zone of active generation)
0.5-1 m/s (100-200
f/min.)
direct spray, spray painting in shallow booths, drum filling, conveyer loading, crusher dusts, gas discharge (active
generation into zone of rapid air motion)
1-2.5 m/s (200-500
f/min.)
grinding, abrasive blasting, tumbling, high speed wheel generated dusts (released at high initial velocity into zone of
very high rapid air motion).
2.5-10 m/s
(500-2000 f/min.)
Within each range the appropriate value depends on:
Lower end of the range
Upper end of the range
1: Room air currents minimal or favourable to capture
1: Disturbing room air currents
2: Contaminants of low toxicity or of nuisance value only.
2: Contaminants of high toxicity
3: Intermittent, low production.
3: High production, heavy use
4: Large hood or large air mass in motion
4: Small hood-local control only
Simple theory shows that air velocity falls rapidly with distance away from the opening of a simple extraction pipe. Velocity generally decreases
with the square of distance from the extraction point (in simple cases). Therefore the air speed at the extraction point should be adjusted,
accordingly, after reference to distance from the contaminating source. The air velocity at the extraction fan, for example, should be a minimum of
1-2 m/s (200-400 f/min) for extraction of solvents generated in a tank 2 meters distant from the extraction point. Other mechanical considerations,
producing performance deficits within the extraction apparatus, make it essential that theoretical air velocities are multiplied by factors of 10 or
more when extraction systems are installed or used.
Personal protection
Eye and face protection
Skin protection
Hands/feet protection
Safety glasses with side shields.
Chemical goggles.
Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing
the wearing of lenses or restrictions on use, should be created for each workplace or task. This should include a review of lens absorption
and adsorption for the class of chemicals in use and an account of injury experience. Medical and first-aid personnel should be trained in
their removal and suitable equipment should be readily available. In the event of chemical exposure, begin eye irrigation immediately and
remove contact lens as soon as practicable. Lens should be removed at the first signs of eye redness or irritation - lens should be removed
in a clean environment only after workers have washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59], [AS/NZS 1336 or
national equivalent]
See Hand protection below
NOTE:
The material may produce skin sensitisation in predisposed individuals. Care must be taken, when removing gloves and other protective
equipment, to avoid all possible skin contact.
Contaminated leather items, such as shoes, belts and watch-bands should be removed and destroyed.
The selection of suitable gloves does not only depend on the material, but also on further marks of quality which vary from manufacturer to
manufacturer. Where the chemical is a preparation of several substances, the resistance of the glove material can not be calculated in advance
and has therefore to be checked prior to the application.
The exact break through time for substances has to be obtained from the manufacturer of the protective gloves and.has to be observed when
making a final choice.
Suitability and durability of glove type is dependent on usage. Important factors in the selection of gloves include:
frequency and duration of contact,
chemical resistance of glove material,
glove thickness and
dexterity
Select gloves tested to a relevant standard (e.g. Europe EN 374, US F739, AS/NZS 2161.1 or national equivalent).
When prolonged or frequently repeated contact may occur, a glove with a protection class of 5 or higher (breakthrough time greater than
240 minutes according to EN 374, AS/NZS 2161.10.1 or national equivalent) is recommended.
When only brief contact is expected, a glove with a protection class of 3 or higher (breakthrough time greater than 60 minutes according to
EN 374, AS/NZS 2161.10.1 or national equivalent) is recommended.

The following information refers to contact allergens as a group and may not be specific to this product.
Contact allergies quickly manifest themselves as contact eczema, more rarely as urticaria or Quincke's oedema. The pathogenesis of
contact eczema involves a cell-mediated (T lymphocytes) immune reaction of the delayed type. Other allergic skin reactions, e.g. contact
urticaria, involve antibody-mediated immune reactions. The significance of the contact allergen is not simply determined by its sensitisation
potential: the distribution of the substance and the opportunities for contact with it are equally important. A weakly sensitising substance
which is widely distributed can be a more important allergen than one with stronger sensitising potential with which few individuals come into
contact. From a clinical point of view, substances are noteworthy if they produce an allergic test reaction in more than 1% of the persons
tested.

Allergic reactions which develop in the respiratory passages as bronchial asthma or rhinoconjunctivitis, are mostly the result of reactions of
the allergen with specific antibodies of the IgE class and belong in their reaction rates to the manifestation of the immediate type. In addition
to the allergen-specific potential for causing respiratory sensitisation, the amount of the allergen, the exposure period and the genetically
determined disposition of the exposed person are likely to be decisive. Factors which increase the sensitivity of the mucosa may play a role in
predisposing a person to allergy. They may be genetically determined or acquired, for example, during infections or exposure to irritant
substances. Immunologically the low molecular weight substances become complete allergens in the organism either by binding to peptides
or proteins (haptens) or after metabolism (prohaptens).
Particular attention is drawn to so-called atopic diathesis which is characterised by an increased susceptibility to allergic rhinitis, allergic
bronchial asthma and atopic eczema (neurodermatitis) which is associated with increased IgE synthesis.
Exogenous allergic alveolitis is induced essentially by allergen specific immune-complexes of the IgG type; cell-mediated reactions (T
lymphocytes) may be involved. Such allergy is of the delayed type with onset up to four hours following exposure.

Iodine is an important element in studies of environmental protection and human health, global-scale hydrologic processes and nuclear nonproliferation. Biogeochemical cycling of iodine is
complex, because iodine occurs in multiple oxidation states and as inorganic and organic species that may be hydrophilic, atmophilic, and biophilic. Experiments illustrate complex behavior with
various processes occurring, including iodate reduction, irreversible retention or mass loss of iodide, and rate-limited and nonlinear sorption. There was an appreciable iodate reduction to iodide,
presumably mediated by the structural Fe(II) in some clay minerals; therefore, careful attention must be given to potential interconversion among species when interpreting the biogeochemical
behavior of iodine in the environment.
Iodine (I2) is electrochemically reduced to ionic iodide by natural processes but humic acid appears to promote the reaction. The different oxidation species of iodine have markedly different
sorption properties. Hence, changes in iodine redox states can greatly affect the mobility of iodine in the environment. A major microbial role has been suggested in the past to account for at least
some of these redox changes. Both soluble ferrous iron and sulfide, as well as iron monosulfide (FeS) were shown to abiologically reduce iodate to iodide. These results indicate that ferric iron
and/or sulfate reducing bacteria are capable of mediating both direct, enzymatic, as well as abiotic reduction of iodate in natural anaerobic environments.
Environmental and geological evidence indicates that iodine can become associated with natural organic matter (NOM) in soils and sediments. Previous studies have shown that iodine

(including 129II) can be strongly retained in organic-rich surface soils and sediment and that soluble iodine may be associated with dissolved humic material. Iodine and iodate undergo an abiotic
pseudo first-order reaction with peat leading to either reduction of iodate or iodine to iodide or incorporation of the iodine atoms into the organic matrix. Iodine appears to be incorporated in
sphagnum peat by aromatic substitution for hydrogen on phenolic constituents of the peat.

SECTION 13 DISPOSAL CONSIDERATIONS
Waste treatment methods
Waste chemicals:
Containers may still present a chemical hazard/ danger when empty.
Return to supplier for reuse/ recycling if possible.
Otherwise:
If container can not be cleaned sufficiently well to ensure that residuals do not remain or if the container cannot be used to store the same
product, then puncture containers, to prevent re-use, and bury at an authorised landfill.
Where possible retain label warnings and MSDS and observe all notices pertaining to the product.
Legislation addressing waste disposal requirements may differ by country, state and/ or territory. Each user must refer to laws operating in their
area. In some areas, certain wastes must be tracked.
A Hierarchy of Controls seems to be common - the user should investigate:
Reduction
Reuse
Recycling
Disposal (if all else fails)
This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use. Shelf life
considerations should also be applied in making decisions of this type. Note that properties of a material may change in use, and recycling or
reuse may not always be appropriate. In most instances the supplier of the material should be consulted.
DO NOT allow wash water from cleaning or process equipment to enter drains.
It may be necessary to collect all wash water for treatment before disposal.
In all cases disposal to sewer may be subject to local laws and regulations and these should be considered first.
Where in doubt contact the responsible authority.
Recycle wherever possible or consult manufacturer for recycling options.
Consult State Land Waste Management Authority for disposal.
Bury residue in an authorised landfill.
Recycle containers if possible, or dispose of in an authorised landfill.
