Calcium Hydroxide 1305-62-0 99 - 100% Yes
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 Contact: Corrosive. May cause severe 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.
Chronic Exposure: Prolonged or repeated skin contact may produce severe
irritation or dermatitis.
Aggravation of Pre-existing Conditions: Persons with pre-existing skin
problems or impaired respiratory function may be more susceptible to the effects
of this substance.
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 Contact: 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.
Eye Contact: Immediately flush eyes with gentle but large stream of water
for at least 15 minutes, lifting lower and upper eyelids occasionally. Call a
physician immediately.
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.
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
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.
Airborne Exposure Limits: -OSHA Permissible Exposure
Limit (PEL):15 mg/m3 (total dust), 5 mg/m3 (respirable fraction)
-ACGIH Threshold Limit Value (TLV):5 mg/m3
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. Please refer to the ACGIH document, Industrial Ventilation, A
Manual of Recommended Practices, most recent edition, for details.
Personal Respirators (NIOSH Approved): If the exposure limit is exceeded
and engineering controls are not feasible, a full facepiece particulate
respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure
limit or the maximum use concentration specified by the appropriate regulatory
agency or respirator supplier, whichever is lowest. If oil particles (e.g.
lubricants, cutting fluids. glycerine, etc.) are present, use a NIOSH type R or
P filter. For emergencies or instances where the exposure levels are not known,
use a full-facepiece positive-pressure, air-supplied respirator. 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.
Eye Protection: Use chemical safety goggles and/or full face shield where
dusting or splashing of solutions is possible. Maintain eye wash fountain and
quick-drench facilities in work area.
Appearance: White crystals or powder.
Odor: Odorless.
Solubility: 0.185 g/100 cc water @ 0C.
Specific Gravity: 2.24
pH: 12.4 (saturated solution)
% Volatiles by volume @ 21C (70F): 0

Evaporation Rate (BuAc=1): No information found.
Stability: Stable under ordinary conditions of use
and storage. Readily absorbs carbon dioxide from air to form calcium carbonate.
Hazardous Decomposition Products: Caustic fumes of calcium oxide form
when heated to decomposition (580C; 1076F).
Hazardous Polymerization: Will not occur.
Incompatibilities: Violent reactions with maleic anhydride, nitroethane,
nitromethane, nitroparaffins, nitropropane, phosphorus. As a strongly alkaline
material, it is incompatible with acids.
Conditions to Avoid: Air, dusting, and incompatibles.
