SWALLOWED
路 If swallowed do NOT induce vomiting.
路 If vomiting occurs, lean patient forward or place on left side (head-down position, if
possible) to maintain open airway and prevent aspiration.

路 Never give liquid to a person showing signs of being sleepy or with reduced awareness;
i.e. becoming unconscious.
路 Give water to rinse out mouth, then provide liquid slowly and as much as casualty can
comfortably drink.

EYE
If this product comes in contact with the eyes:
路 Wash out immediately with fresh running water.
路 Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and
moving the eyelids by occasionally lifting the upper and lower lids.

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
Wear chemical protective gloves, eg. PVC.
Wear safety footwear.

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
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 favourable to 1: Disturbing room air currents
capture
2: Contaminants of low toxicity or of nuisance 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 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.

control.
EYE
The dust is. slightly discomforting to the eyes and is capable of causing a mild,
temporary redness of the conjunctiva (similar to wind-burn), temporary impairment of
vision and/ or other transient eye damage/ ulceration.
SKIN
The material may be. discomforting to the skin and is capable of causing skin reactions
which may lead to dermatitis from repeated exposures over long periods or if exposure is
prolonged.
INHALED
The dust is. discomforting to the upper respiratory tract.
CHRONIC HEALTH EFFECTS
Principal routes of exposure are by accidental skin and eye contact and inhalation of
generated dusts.
No human exposure data available. For this reason health effects described are based on
experience with chemically related materials.
As with any chemical product, contact with unprotected bare skin; inhalation of vapour,
mist or dust in work place atmosphere; or ingestion in any form, should be avoided by
observing good occupational work practice.
