IDENTIFICATION OF THE SUBSTANCE:
SILICA
SAND
2.
COMPOSITION / INFORMATION ON INGREDIENTS
Salica
sands are typically composed of a minimum of
97% quartz and have a varity of uses in industrial and
ceramic applications.
3.HAZARDS
IDENTIFICATION
Prolonged
exposure to the fine airborne particales
may be harmful due to the inhalation of respirable
crystalline silica.
Silica sand can cause gastrcintestinal irritation if
in ingested.
Not recommended for dry sand blasting
GENERAL
- unlikely tobe hazardous if handled
correctly.
SKIN
- wash with soap and water.
EYES
- lrrigate with copious amounts of water and
obtain medical attention if soreness persists.
INGESTION
- give water to drink and seek medical

RELEASE MEASURES
Personal
Precautions - Do not breathe fine dust.
In areas with insufficient ventilation wear suitable respiratory protection
equipment,
ENVIRONMENTAL PRECAUTIONS - No Denger,
METHODS FOR CLEANING - Vauum system. Utilise water spraying to prevent
airborne dust.
Avoid dry sweeping, which creates dust.
HANDLING
*assess manul handling requirements
*handle to minimise the creation of airborne dust
*avoid inhaling dust.
STORAGE
OF DRY SILICA SAND
*bags should be palletised and stored in
ventilated area
*bulk storage in silos should be vented through
suitable arrestment equipment.

TRANSPORT INFORMATION:
Special
carriage precautions-nil, material suitable for bulk tankers and sealed
bags.
EYE
PROTECTION - protection is recommended
15.
REGULATORY INFORMATION
SUPPLY
LABEL INFORMATION- Not subject to
the hazardous substance conveyance regulation
and lablling is not required . the product itself is not
classifide as a hazardous product but contains an
amount of crystalline silica which is classified
as R20. hower as the amount will always be below
25% it dose not make the product hazardous.
RISK
PHRASES & SAFETY PHRASES
R20- harmful by inhalation
S22- do not breathe dust.
