NOTES TO PHYSICIAN
Treat symptomatically.
Section 5 - FIRE FIGHTING MEASURES
EXTINGUISHING MEDIA
鈥? There is no restriction on the type of extinguisher which may be used.
FIRE FIGHTING
鈥? Alert Fire Brigade and tell them location and nature of hazard.
鈥? Wear breathing apparatus plus protective gloves for fire only.
鈥? Prevent, by any means available, spillage from entering drains or water
courses.
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.

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.

Section 8 - EXPOSURE CONTROLS / PERSONAL PROTECTION
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).
PERSONAL PROTECTION
EYE
鈥? Safety glasses with side shields; or as required,
鈥? Chemical goggles.
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
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].
HANDS/FEET
Wear chemical protective gloves, eg. PVC.
Wear safety footwear.

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? Exhaust ventilation should be designed to prevent accumulation and
recirculation of particulates in the workplace.
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
鈥? Build-up of electrostatic charge on the dust particle, 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.
Air contaminants generated in the workplace possess varying "escape" velocities
which, in turn, determine the "capture velocities" of fresh circulating air
required to efficiently 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:
Lower end of the range Upper end of the range
1: Room air currents minimal or 1: Disturbing room air currents
favourable to capture
2: Contaminants of low toxicity or of 2: Contaminants of high toxicity
nuisance value only
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in 4: Small hood-local control only
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

Section 11 - TOXICOLOGICAL INFORMATION
SKIN
The material may be mildly discomforting to the skin and is capable of causing
skin reactions which may lead to dermatitis.
Open cuts, abraded or irritated skin should not be exposed to this material.
INHALED
The dust may be discomforting to the upper respiratory tract.
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.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and
inhalation of generated dusts. Chronic excessive intake of iron have been
associated with damage to the liver and pancreas. People with a genetic
disposition to poor control over iron are at an increased risk. Iron overload in
men may lead to diabetes, joint inflammation, liver cancer, heart irregularities
and problems with other organs.
