MATERIAL DATA
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:
路 the architecture of the air spaces remain intact,
路 scar tissue (collagen) is not synthesised to any degree,
路 tissue reaction is potentially reversible.
Extensive concentrations of P.N.O.C.s may:
路 seriously reduce visibility,
路 cause unpleasant deposits in the eyes, ears and nasal passages,
路 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:
路 to brief exposures to higher concentrations
路 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
路 are insoluble or poorly soluble* in water or, preferably, in aqueous lung fluid (if
data is available) and
路 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
路 Safety glasses with side shields
路 Chemical goggles.
路 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
Suitability and durability of glove type is dependent on usage. Factors such as:
路 frequency and duration of contact,
路 chemical resistance of glove material,
路 glove thickness and
路 dexterity,
are important in the selection of gloves.

ENGINEERING CONTROLS
路 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.
路 Exhaust ventilation should be designed to prevent accumulation and recirculation of
particulates in the workplace.
路 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
路 Build-up of electrostatic charge on the dust particle, may be prevented by bonding and
grounding.
路 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 shallow booths, 1- 2.5 m/s (200- 500 f/min.)
drum filling, conveyer loading, crusher dusts,
gas discharge (active generation into zone of
rapid air motion)
grinding, abrasive blasting, tumbling, high 2.5- 10 m/s (500- 2000 f/min.)
speed wheel generated dusts (released at high
initial velocity into zone of very high rapid

value only
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 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
POTENTIAL HEALTH EFFECTS
ACUTE HEALTH EFFECTS
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.
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.
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.
Long-term exposure to the product is not thought to produce chronic effects adverse to
the health (as classified by EC Directives using animal models); nevertheless exposure by
all routes should be minimised as a matter of course.
TOXICITY AND IRRITATION
unless otherwise specified data extracted from RTECS - Register of Toxic Effects of Chemical Substances.
TOXICITY IRRITATION
