Section 5 - FIRE FIGHTING MEASURES
鈥? Use fire fighting procedures suitable for surrounding area.
鈥? DO NOT approach containers suspected to be hot.
鈥? Cool fire exposed containers with water spray from a protected location.
鈥? If safe to do so, remove containers from path of fire.
鈥? Equipment should be thoroughly decontaminated after use.
FIRE/EXPLOSION HAZARD
鈥? Solid which exhibits difficult combustion or is difficult to ignite.
鈥? Avoid generating dust, particularly clouds of dust in a confined or
unventilated space as dusts may form an explosive mixture with air, and any
source of ignition, i.e. flame or spark, will cause fire or explosion. Dust
clouds generated by the fine grinding of the solid are a particular hazard;
accumulations of fine dust may burn rapidly and fiercely if ignited
鈥? Dry dust can also be charged electrostatically by turbulence, pneumatic
transport, pouring, in exhaust ducts and during transport.
鈥? Build-up of electrostatic charge may be prevented by bonding and grounding.
鈥? Powder handling equipment such as dust collectors, dryers and mills may
require additional protection measures such as explosion venting.
鈥? All movable parts coming in contact with this material should have a speed of
less than 1-meter/sec.
Decomposition may produce toxic fumes of, carbon dioxide (CO2), other pyrolysis
products typical of burning organic material.
May emit poisonous fumes.
FIRE INCOMPATIBILITY
Avoid contamination with oxidising agents i.e. nitrates, oxidising acids,
chlorine bleaches, pool chlorine etc. as ignition may result.
HAZCHEM

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
These "dusts" have little adverse effect on the lungs and do not produce toxic
effects or organic disease. Although there is no dust which does not evoke some
cellular response at sufficiently high concentrations, the cellular response
caused by P.N.O.C.s has the following characteristics:
鈥? the architecture of the air spaces remain intact,
鈥? scar tissue (collagen) is not synthesised to any degree,
鈥? tissue reaction is potentially reversible.
Extensive concentrations of P.N.O.C.s may:
鈥? seriously reduce visibility,
鈥? cause unpleasant deposits in the eyes, ears and nasal passages,
鈥? contribute to skin or mucous membrane injury by chemical or mechanical action,
per se, or by the rigorous skin cleansing procedures necessary for their
removal. [ACGIH]
This limit does not apply:
鈥? to brief exposures to higher concentrations
鈥? nor does it apply to those substances that may cause physiological impairment
at lower concentrations but for which a TLV has as yet to be determined.
This exposure standard applies to particles which
鈥? are insoluble or poorly soluble* in water or, preferably, in aqueous lung
fluid (if data is available) and
鈥? have a low toxicity (i.e.. are not cytotoxic, genotoxic, or otherwise
chemically reactive with lung tissue, and do not emit ionizing radiation, cause
immune sensitization, or cause toxic effects other than by inflammation or by a
mechanism of lung overload).

Operations which produce a spray/mist or fume/dust, introduce particulates to

PERSONAL PROTECTION

鈥? Contact lenses may pose a special hazard; soft contact lenses may absorb and
concentrate irritants. A written policy document, describing the wearing of lens
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

ENGINEERING CONTROLS
鈥? Local exhaust ventilation is required where solids are handled as powders or
crystals; even when particulates are relatively large, a certain proportion will
be powdered by mutual friction.
鈥? If in spite of local exhaust an adverse concentration of the substance in air
could occur, respiratory protection should be considered.
Such protection might consist of:
(a): particle dust respirators, if necessary, combined with an absorption
cartridge;
(b): filter respirators with absorption cartridge or canister of the right type;
(c): fresh-air hoods or masks
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.
Type of Contaminant: Air Speed:
direct "spray " spray painting in 1-2.5 m/s (200-500 f/min.)
shallow "booths " drum "filling "
conveyer "loading " crusher "dusts "
gas discharge (active generation into
zone of rapid air motion)
grinding " abrasive "blasting " 2.5-10 m/s (500-2000 f/min.)
"tumbling " high speed wheel generated
dusts (released at high initial
velocity into zone of very high rapid
air motion).
Within each range the appropriate value depends on:

motion
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 4-10 m/s (800-2000 f/min)
for extraction of crusher dusts generated 2 metres 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.

Section 11 - TOXICOLOGICAL INFORMATION
SWALLOWED
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 (eg.
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.
EYE
Although the material is not thought to be an irritant (as classified by EC
Directives), direct contact with the eye may cause transient discomfort
characterised by tearing or conjunctival redness (as with windburn). Slight
abrasive damage may also result. The material may produce foreign body
irritation in certain individuals.
SKIN
The material is not thought to produce adverse health effects or skin irritation
following contact (as classified by EC Directives using animal models).
Nevertheless, good hygiene practice requires that exposure be kept to a minimum
and that suitable gloves be used in an occupational setting.
Entry into the blood-stream, through, for example, cuts, abrasions 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.
INHALED
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.
Not normally a hazard due to non-volatile nature of product.
CHRONIC HEALTH EFFECTS
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. Prime symptom is breathlessness; lung
shadows show on X-ray. Substance accumulation, in the human body, may occur and
may cause some concern following repeated or long-term occupational exposure.
There has been some concern that this material can cause cancer or mutations but
there is not enough data to make an assessment. Prolonged use of Vitamin C is
associated with formation of kidney stones in some persons.

DO NOT discharge into sewer or waterways.
Section 13 - DISPOSAL CONSIDERATIONS
If container can not be cleaned sufficiently well to ensure none of the original
product remains 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.
