Crystalline Quartz Silica
Specific Chemical Identity:
Quartz (Silicon Dioxide), SiO2
These "Hazardous Components" are not released under
normal conditions of use, but may be released from the cured
concrete block as airborne respirable free crystalline silica
particles when dry-sawing, dry-grinding, or otherwise materially
modifying the product.
Common Names: Dust from dry sawing or grinding, sand,
Exposure to airborne crystalline silica shall not exceed an 8-hour
time-weighted average limit as stated in 29 CFR 1910.1000 Table
Z-3 for Mineral Dusts, specifically: Silica, Crystalline Quartz
(respirable): 0.1 mg/M3
TLV-TWA = 0.1 mg/M3 (Respirable Dust)
See Threshold Limit Value and Biological Exposure Indices for
1991-1992, American Conference of Governmental Industrial Hygienists.
Other Limits Recommended:
NIOSH has recommended that the permissible exposure limit be
changed to 0.05 mg/M3 (as respirable free silica) averaged over
a work shift of up to 10 hours per day, 40 hours per week. Consult
the NIOSH Criteria Document for Crystalline Silica for more information.

SECTION II - Hazardous Ingredients/Identity
SECTION III - Physical/Chemical Characteristics
SECTION IV - Fire and Explosion Hazard
Stability: Stable Conditions to Avoid:
Silica will dissolve in hydrofluoric acid and produce a corrosive
gas, silicon tetra fluoride.
Hazardous Decomposition or
Hazardous Polymerization: Will not occur. Conditions
to Avoid: None
Route(s) of Entry:
Inhalation ? : Yes S k i n ? : No Ingestion
? : No
Health Hazards (Acute and Chronic):
Dry-sawing or dry-grinding will result in the release of dust
particles, which can result in acute and chronic conditions.
Acute: Short-term exposure can cause minor irritation
of the eye, nose, or skin.
Chronic: Excessive inhalation of dust particles for prolonged
periods may result in lung disease (silicosis). Silicosis is
a form of disabling pulmonary fibrosis, which can be progressive
and may lead to death. See "Carcinogenicity" section
NTP? : Yes.
In the Sixth Annual Report on Carcinogens by The National Toxicology
Program (NTP), it was concluded that respirable crystalline silica
may reasonably be anticipated to be a carcinogen. The conclusion
is based on sufficient evidence of carcinogenicity in laboratory
animals, and limited evidence in humans.
IARC Monographs? : Yes.
The International Agency for Research on Cancer (IARC) Monographs
on the Evaluation of the Carcinogenic Risk of Chemicals to Humans
(Vol. 42, 1987) concludes that there is sufficient evidence for
the carcinogenicity of crystalline silica to experimental animals,
and that there is limited evidence of the carcinogenicity of
crystalline silica to humans. IARC Class 2A.
Signs and Symptoms of Exposure
Symptoms of excessive exposure are irritation of eyes, nose and/or
throat, shortness of breath, or sputum production.
Medical Conditions Generally
Aggravated by Exposure:
Pre-existing pulmonary and/or respiratory lung diseases, including,
but not limited to; Emphysema, Asthma, or Bronchitis. Pulmonary
function may be reduced by inhalation of respirable crystalline
silica. Lung scarring produced by excessive inhalation may lead
to a progressive massive fibrosis of the lung which may aggravate
other pulmonary conditions and diseases, increasing susceptibility
to pulmonary tuberculosis. Progressive massive fibrosis may be
accompanied by heart enlargement, heart failure, and pulmonary
failure. Smoking aggravates the effects of exposure. Sensitive
eye conditions may also be aggravated by excessive exposure.
Emergency and First Aid Procedures:
Eyes : Flush eyes immediately
and generously with water for 15 minutes. If irritation persists,
seek medical attention.
Inhalation : For gross inhalation, remove person immediately
to fresh air. Giveartificial respiration as needed, and seek
medical attention as needed.
Skin : Wash thoroughly. See physician if irritation persists.
SECTION V - REACTIVITY DATA
SECTION VI - Health Hazard Data
Steps to Be Taken in
Case Material is Released or Spilled: Collect dust from dry-sawing or grinding operations
using dustless method (vacuum or water). Wear protective equipment
Waste Disposal Method: Dispose in accordance with Federal,
State, and Local regulations.
Precautions to Be Taken in Handling and Storing: Avoid
breathing of dust particles from dry-sawing and grinding of units.
Take normal precautions against spilling of containers with waste
dust particles from dry-sawing or grinding operations.
It is strongly recommended that wet cutting
or grinding methods be employed. Water will radically reduce
the risk to exposure, because dust will be greatly minimized
If dry cutting and grinding is required take measures to dust
collect (vacuum) where possible. Always wear a NIOSH approved
respirator, tight fitting goggles, and gloves when any sawing
or grinding operations are active. Do not permit dust to collect
on wall or floor surfaces, clothing, or equipment.
See applicable OSHA Hazard Communication Rule 29 CFR Sections
and State and Local worker or community "right to know"
laws and regulations. We recommend that smoking be prohibited
in all areas where respirators must be used.
WARN YOUR EMPLOYEES AND (YOUR CUSTOMER-USERS IN CASE OF RESALE)
BY POSTING AND OTHER MEANS OF THE HAZARD AND OSHA PRECAUTIONS
TO BE USED. PROVIDE TRAINING FOR YOUR EMPLOYEES ABOUT THE OSHA
See also the ASTM E 1132-86, "Standard Practice for Health
Requirements Relating to Occupational Exposure to Quartz Dust."
NOTE: THESE CONTROL MEASURES ARE TO BE USED WHEN DRY-SAWING,
DRY-GRINDING, OR OTHER MATERIAL MODIFYING OPERATIONS ARE ACTIVE.
NORMAL CONDITIONS OF USE AND/OR INSTALLATIONS OF CLAY BRICK,
CONCRETE BLOCK or CONCRETE PAVER ARTICLES DO NOT REQUIRE RESPIRATORY
Respiratory Protection: Use NIOSH approved Particulate Respirator.
Provide additional conventional respiratory protection based
on considerations of airborne concentrations and duration of
exposure. See most recent standards of the following: American
National Standard Institute (ANSI Z.88.2) Occupational Safety
and Health Administration (OSHA 29 CFR Part 1910.134) Mine Safety
and Health Administration (MSHA 30 CFR Part 56)

Ventilation : Local Exhaust: Meet PEL requirements set
out above in Section II.
Special : N/A Other: N/A
Mechanical (General): When cutting in confined area, meet
Protective Gloves : Recommended.
Eye Protection : Tight fitting protective goggles.
Other Protective Clothing or Equipment: As needed.
Work/Hygienic Practices: Avoid creating and breathing
dust (see Other Precautions, Sec. VII.)
