Product Name: Hi-Yield(R) Horticultural Hydrated Lime ID Number: Page: 1
Hydrated lime in itself is not flammable but when in contact with water, it could hydrate further evolving heat which
could ignite paper, wood, or rags which may be in contact with the agent during the hydration process.
SPECIAL FIRE FIGHTING PROCEDURES
Do not touch spilled material. Cool containers with flooding amounts of water. Utilize self-contained breathing
apparatus with full facepiece operated in pressure demand or other positive pressure mode.
SECTION 5 - HEALTH INFORMATION
PRIMARY ROUTES OF EXPOSURE AND TARGET ORGANS
Inhalation, skin and eye contact, ingestion
SIGNS AND SYMPTOMS OF EXPOSURE
(1) ACUTE OVEREXPOSURE
Inhalation may cause irritation and ulceration of the respiratory passages. Skin contact may result in irritation with
erythema, blistering and possible burns which may result in brownish stains. Eye contact may result in severe
corneal burns and may result in blindness. Ingestion may result n alkaline burns of the mouth, mucous membranes,
esophagus and stomach. Symptoms of respiratory discomfort, vomiting, and diarrhea may occur and may lead to
weak and rapid pulse, shallow respiration, circulatory collapse and renal failure.
(2) CHRONIC OVEREXPOSURE
Inhalation and ingestion may result in inflammatory and ulcerative changes in the mouth, bronchial, and
gastrointestinal disturbances. Skin contact ma leas to dermatitis. Eye contact may result in conjunctivitis. Repeated
or prolonged ingestion may result in metabolic acidosis.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE
Disorders of the eyes, skin, respiratory and digestive systems.
CHEMICAL/COMPONENT LISTED AS CARCINOGEN OR POTENTIAL CARCINOGEN
None
NTP IARC OSHA
YES NO YES NO YES NO
OTHER EXPOSURE LIMITS
None determined
EMERGENCY AND FIRST AID PROCEDURES
INHALATION: Remove to fresh air. If not breathing, give artificial respiration, preferably mouth-to-mouth. If breathing is
difficult give oxygen. Call a physician. SKIN OR EYE CONTACT: Immediately flush eyes with water for at least 15
minutes. Vigorous irrigation dislodges some particles mechanically, but for complete cleansing, it may be necessary
to double evert the lids and swab or brush material from the fornices. Special efforts must be made to remove the
deposits promptly in order to avoid prolonged exposure to the eye to a continuing source of calcium hydroxide. Call a
physician. Flush skin with water. Wash clothing before reuse. INGESTION: Induce vomiting immediately by giving
two glasses of water and sticking finger down throat. Never give anything by mouth an unconscious person. Call a
physician. Examine victim for possible corrosive injury to mouth and throat.
SECTION 6 - REACTIVITY DATA
STABILITY CONDITIONS TO AVOID
Unstable Stable Contact with water or acid will evolve heat.
INCOMPATIBILITY (Materials to Avoid)
Chlorinated phenols + potassium nitrate, maleic anhydride, nitroethane, nitroparaffins, and phosphorous.
HAZARDOUS DECOMPOSITION PRODUCTS
Thermal decomposition will produce calcium oxide or lime.
HAZARDOUS POLYMERIZATION CONDITIONS TO AVOID
May Occur Will Not occur Does not apply

container for disposal or reuse. Keep unnecessary people away. Comply with all applicable governmental regulations
concerning spill reporting, handling, and disposal of waste.
WASTE DISPOSAL METHOD
Dispose of in accordance with Federal, State, and local regulation.
SECTION 8 - PERSONAL PROTECTION INFORMATION
RESPIRATORY PROTECTION
NIOSH/MSHA approved respiratory devices to provide high-efficiency protection against dusts.
VENTILATION
General or local exhaust to maintain employee exposure below the TLV/PEL.
PROTECTIVE GLOVES
Appropriate gloves to prevent skin contact.
EYE PROTECTION
Splash-proof or dust-resistant safety goggles to prevent eye contact with this substance. Contact lenses should not
be worn.
OTHER PROTECTIVE CLOTHING OR EQUIPMENT
When necessary utilize impervious clothing and other equipment to prevent skin contact with this substance.
SECTION 9 - SPECIAL PRECAUTIONS
PRECAUTIONS TO BE TAKEN IN HANDLING & STORING
Store in a dry area away from incompatible substances.
OTHER PRECAUTIONS
Prolonged contact with hydrated lime in the presence of moisture may cause irritation or burns. Do not allow hydrated
lime dust to accumulate on exposed skin or clothing.
