Chrome Spinel Sand ( common name Chromite Sand ) is a complex compound of various elements.
The main elements are listed above.
The above elements, except Silica are part of the Spinel structure and as such cannot be separated
from the sand gain. Silica is a tramp element and can be found as Silica, Magnesium Silicate (
Serpentine ) and Aluminium Silicates.

SECTION 4 - FIRE AND EXPLOSION DATA
Flash point: None
Flammable limits - Lel: N/A Uel: N/A
Extinguishing media: N/A
Special fire fighting procedures: N/A
Unusual fire & explosion hazards: None
SECTION 5 - REACTIVITY DATA
Stability: Stable.
Incompatibility (materials to avoid): N/A
Hazardous polymerisation: Will not occur.
Hazardous decomposition products (including combustion products): None
SECTION 6 - HEALTH HAZARD DATA
NOTE: As shipped, this product does not pose an inhalation hazard, as it contains essentially no
particles in the respirtable size range. If during use and handling particles are broken down to a
size that can be inhaled; the dusts will be harmful to the respiratory system. Silica fraction will
cause silicosis.
Route(s) of entry: INHALATION - Yes SKIN - Yes EYES - Yes INGESTION - No
Health Hazards: Acute - N/A
Health Hazards: Chronic - Inhalation of dusts can cause silicosis of lugs.
Toxicity data: N/A
Cacinogenicity: see notes
Signs and symptoms of exposure: Respiratory irritation.
Medical conditions aggravated by exposure: Pre-existing respiratory ailments.
Suspected cancer agent?
Federal OSHA no NTP yes IARC yes
NIP:Respirtable Crystalline Silica has been listed in the 6th Annual Report on Carcinogens
IARC: Monographs on the Evaluation of the Carcinogenic Risk of Chemicals to Humans (vol. 68,
1997) concludes that there is sufficient evidence in humans for the carcinogenicity of inhaled
crystalline silica in the forms of quartz and cristobalite (Group 1) in certain industrial
circumstances, but that carcinogenicity may be dependent on inherent characteristics of the
crystalline silica or on extemal factors affecting its biological activity or distribution of its
polymorphs.
Hexavalent compounds, potentially present used product, are irritants of respiratory tract and skin,
and repeated or prolonged exposure may increase risk of cancer.
