3. HAZARDS IDENTIFICATION
* * * * * * * EMERGENCY OVERVIEW * * * * * * *
Variable white, gray or tan powder. Inhalation of excessive amounts of dust from the product may
cause upper respiratory irritation. Calcium oxide causes severe irritation and burns to every area
of contact. Cancer hazard 鈥? free crystalline silica may cause cancer
ROUTES OF ENTRY: Inhalation, eyes, skin
HUMAN EFFECTS AND SYMPTOMS OF OVEREXPOSURE:
ACUTE INHALATION: Dust is irritating and possible corrosive to the respiratory system and
mucous membranes
ACUTE SKIN CONTACT: May cause corrosive damage
ACUTE EYE CONTACT: Severe irritation. May damage eye tissues, cause redness, tearing,
blurred vision and pain
ACUTE INGESTION: Calcium oxide may cause alkali burns in mouth and throat

3. HAZARDS IDENTIFICATION (Continued)
CHRONIC EXPOSURE: Free crystalline silica may cause silicosis, shortness of breath caused
by lung scarring, pain in chest, and coughing. Inflammation of the
respiratory passages, ulcers of the mucous membranes, and
perforation of nasal septum may occur
CARCINOGENICITY:
ACGIH: Free crystalline silica is listed as a suspected human carcinogen in Notice of
Intended Changes
NTP: Respirable silica may reasonably be anticipated to be a carcinogen
IARC: Crystalline silica in the form of quartz or cristobalite has been classified as
carcinogenic to humans
OSHA: No
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Persons with
pre-existing skin disorders, eye problems, or impaired respiratory function may be more
susceptible to the effects of the dust
4. FIRST AID MEASURES
INHALATION: Remove victim to fresh air, if not breathing, give artificial respiration. If any
symptoms or irritation persist, contact a physician
SKIN: Immediately flush skin with water for at least 15 minutes. If any symptoms or
irritation persist, contact a physician
EYE: Flush with large amounts of water for 15 minutes. If any symptoms or irritation
persist, contact a physician
INGESTION: Do not induce vomiting, give large quantities of water or milk. Get medical
attention
5. FIRE FIGHTING MEASURES
FLASH POINT: Not Combustible
AUTO IGNITION TEMPERATURE: Not Applicable
LOWER FLAMMABLE LIMIT: Not Applicable
UPPER FLAMMABLE LIMIT: Not Applicable
HAZARDOUS COMBUSTION PRODUCTS: None
FIRE AND EXPOSURE HAZARD: Not combustible. Not sensitive to explosion. Will not support
combustion
EXTINGUISHING MEDIA: Not combustible. Use media appropriate for surrounding fire
SPECIAL FIRE FIGHTING PROCEDURES: Does not burn. SCBA required for standard fire fighting
6. ACCIDENTIAL RELEASE MEASURES:
SPILL OR LEAK PROCEDURES: Stop source of spill. Wear appropriate PPE. Pick up and place in a
suitable container for reclamation or disposal using a method that does not generate dust. Alkaline
materials will generate heat when moistened. Keep material away from water bodies and sewers
7. HANDLING AND STORAGE:
PRECAUTIONS: Protect against physical damage and store in dry place away from water moisture,
and incompatible materials. Wear appropriate personal protective equipment as specified in
Section 8
Page 2 of 4
8. EXPOSURE CONTROLS/PERSONAL PROTECTION:
EYE PROTECTION: Mechanical or chemical goggles for dust
SKIN PROTECTION: Use impervious gloves are appropriate when handling wet product. Wear
other impervious protective clothing, including boots, as appropriate to prevent skin contact
RESPIRATORY PROTECTION: Use NIOSH approved respirators with HEPA or P100 filters. Higher
dust levels may require a powered air-purifying respirator with HEPA or P100 filter, or a positive
pressure supplied air respirator
ENGINEERING CONTROLS: Not needed in open spaces. If excessive dust levels are generated at
transfer points, local exhaust ventilation may be needed
