SECTION III - HAZARDS
IDENTIFICATION
Emergency Overview: This product contains
crystalline silica which is considered a chronic health hazard by inhalation.
The International Agency for Research on Cancer (IARC) has classified occupational
exposures to respirable crystalline silica as being carcinogenic to humans (Class
1). This classification is based on what IARC considered sufficient evidence
from epidemiological studies of humans for the carcinogenicity of inhaled silica
in the forms of quartz and cristobalite. Crystalline silica is also known to
cause Silicosis, a non-cancerous lung disease.
WHMIS Class: D-2A - Material causing other toxic effects (VERY TOXIC
- Chronic)
Primary Routes of Entry: Via respirable dust to the
lungs and respiratory system and via coarse dust and particulate to the eyes.
Primary Target Organs: Lungs, respiratory system and
eyes.
Potential Health Effects:
Inhalation: Long term overexposure to respirable
crystalline silica dust may cause permanent and irreversible lung damage including
silicosis.
Skin Contact: Possible dryness or irritation resulting
from long term exposures to product dust.
Eye Contact: A mechanical irritant which can cause
moderate to severe eye irritation.
Ingestion: Non-hazardous when
ingested. Potentially a mild Irritant to the GI tract if excessive quantity
is ingested.
Medical Conditions Aggravated by Exposure: Pre-existing
chronic upper respiratory and lung diseases such as, but not limited to, bronchitis,
emphysema and asthma.
Carcinogenicity: This product
contains crystalline silica which is classified as a class 1, human carcinogen
by IARC, as a suspect carcinogen by NTP and as a possible select carcinogen
by OSHA.
SECTION IV - FIRST AID
MEASURES
Inhalation: Remove to fresh air. Drink
water to clear throat and blow nose to evacuate dust. If coughing and irritation
develop, call a physician.
Eye Contact: Flush with large amounts of water until
irritation subsides, as least 15 minutes. See a physician if irritation persists.
Skin Contact: Normal good personal hygiene practices.
Wash with mild soap and warm water after each exposure.
Ingestion: Emergency procedures not normally required.
May be a temporary irritant to the GI system.
SECTION V - FIREFIGHTING
MEASURES
NFPA Rating:
Health: 0
Fire: 0
Reactivity: 0
Other: 0
Flashpoint and Method:This is
a non-flammable product

Fire or explosion Hazards:
The brick products described above are non-flammable. However, the cardboard
packaging is combustible, and due care should be taken to minimize fire
hazards.
SECTION VI - ACCIDENTAL
RELEASE MEASURES
Clean-up Procedures: Shovel material
into waste container taking care to minimize dust. Wet down if necessary to
control dust. Vacuum clean dust with equipment fitted with HEPA filter
Personal Precautions: If dusty conditions exist, wear
a face mask approved for use with dusts such as 3M 8511 N-95 or equivalent.
SECTION VIII - EXPOSURE
CONTROLS/PERSONAL PROTECTION
Respiratory Protection: When over
PEL/TLV wear an approved face mask such as 3M 8511 N-95 or equivalent, to protect
against silica and pneumoconiosis producing dust. Concentrations of dust that
exceed the recommendations of the dust mask manufacturer will need a higher
level of respiratory protection, such as a half mask respirator with appropriate
dust filters.
Eye Protection: Wear safety glasses with side shields,
goggles or face shield when cutting, milling or abrading to protect eyes against
dust and particulate.
Skin Protection: Under normal conditions the wearing
of protective gloves and clean, body-covering clothing should be adequate.
Engineering Controls: Maintain sufficient mechanical
or natural ventilation to assure dust concentrations remain below PEL/TLV. Use
local exhaust if necessary. Power equipment should be equipped with properly
designed dust collection devices.
