Accident:
SECTION II - HAZARD IDENTIFICATION
Emergency Overview: DANGER! HARMFUL IF SWALLOWED OR INHALED. CAUSES BURNS TO SKIN AND
EYES. CAUSES SEVERE IRRITATION TO RESPIRATORY TRACT.
Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath.
Can cause chemical bronchitis.
Ingestion: Gastric irritant. Ingestion may be followed by severe pain, vomiting, diarrhea, and collapse. If
death does not occur in 24 hours, esophageal perforation may occur, as evidenced by fall in
blood pressure and severe pain. A narrowing of the esophagus may occur weeks, months, or
years after ingestion, making swallowing difficult.
Skin: Corrosive. May cause sever burns and blistering, depending on duration of contact.
Eye Contact: Corrosive. May produce severe irritation and pain. May induce ulcerations of the corneal
epithelium. Can cause blindness.
Prolonged or repeated skin contact may produce severe irritation or dermatitis.
Chronic Exposure:
Persons with pre-existing skin problems or impaired respiratory function may be more
Aggravated by
susceptible to the effects of this substance
Exposure:
SECTION III - COMPOSITION / INFORMATION ON INGREDIENTS
CAS #: CHEMICAL NAME
Calcium Hydroxide 95 to 100%
1305-62-0
SECTION IV - FIRST AID MEASURES
Inhalation: Remove to Fresh Air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Call a physician immediately.
Ingestion: DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to
an unconscious person. Call a physician immediately.
Skin: In case of contact, wipe off excess material from skin then immediately flush skin with plenty of
water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before
reuse. Call a physician immediately.
In case of Contact, Immediately Flush Eyes with Plenty of Water for at Least 15 Minutes, Lifting
Eyes:
Upper and Lower Eyelids Occasionally. Call a physician immediately.
SECTION V - FIRE FIGHTING MEASURES
Fire: Not Considered to be a Fire Hazard.
Explosion: Not Considered to be an Explosion Hazard.
Fire Extinguishing Media: Use any means Suitable for Extinguishing Surrounding Fire.
Special Information: In the Event of a Fire, Wear Full Protective Clothing and NIOSH-Approved Self-Contained
Breathing Apparatus with Full Facepiece Operated in the Pressure Demand or Other Positive
Pressure Mode.
SECTION VI - ACCIDENTAL RELEASE MEASURES
Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of
spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Pick up
and place in a suitable container for reclamation or disposal, using a method that does not
generate dust. Do not flush caustic residues to the sewer. Residues from spills can be diluted
with water, neutralized with dilute acid such as acetic, hydrochloric or sulfuric. Absorb
neutralized caustic residue on clay, vermiculite or other inert substance and package in a

suitable container for disposal.
SECTION VII - HANDLING AND STORAGE
Keep in a Tightly Closed Container, Stored in a Cool, Dry, Ventilated Area. Protect against
Physical Damage. Isolate from incompatible substances. Containers of this material may be
hazardous when empty since they retain product residues (dust, solids). Observe all warnings
and precautions listed for the product.
SECTION VIII - EXPOSURE CONTROL / PERSONAL PROTECTION
OSHA Permissible Exposure Limit (PEL): 15 mg/m3 Total Dust, 5 mg/m3 Respirable Fraction for
Airborne Exposure Limits:
3
Nuisance Dusts. ACGIH Threshold Limit Value (TLV): 5 mg/m Total Dust.
Ventilation System: A System of Local and/or General Exhaust is Recommended to Keep Employee Exposures
Below the Airborne Exposure Limits. Local Exhaust Ventilation is Generally Preferred Because it
can Control the Emissions of the Contaminant at its Source, Preventing Dispersion of it into the
General Work Area.
Personal Respirators: If the Exposure Limit is Exceeded, a Half-Face Dust/Mist Respirator may be Worn for up to Ten
(NIOSH APPROVED) Times the Exposure Limit or the Maximum use Concentration Specified by the Appropriate
Regulatory Agency or Respirator Supplier, Whichever is Lowest. A Full-Facepiece Dust/Mist
Respirator may be Worn up to 50 Times the Limit, or the Maximum use Concentration Specified
by the Appropriate Regulatory Agency, or Respirator Supplier, Whichever is Lowest.
WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection: Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as
appropriate, to prevent skin contact.
Use Chemical Safety Goggles and/or full-face shield where dusting or splashing of solutions is
Eye Protection:
possible. Maintain Eye Wash Fountain and Quick-Drench Facilities in Work Area.
