HAZARD IDENTIFICATION
EMERGENCY OVERVIEW:
ΔWARNING!
This product is not expected to produce any unusual hazards during normal use. Exposure to high dust levels may
irritate the skin, eyes, nose, throat, or upper respiratory tract. Hydrated lime and sodium hydroxide (caustic soda) are
strongly alkaline and can cause severe injury. Contact with eyes or skin can cause irritation and possible irreversible
tissue damage, corrosion damage, chemical burning and corneal damage. Wear eye and skin protection. Particulate
will also cause mechanical irritation. Inhalation of dust can cause severe upper respiratory irritation. Contact lenses
should not be worn when working with hydrated lime or caustic soda.
POTENTIAL HEALTH EFFECTS (See Section 11 for more information)
ACUTE :
Inhalation
Exposure to dust generated during the handling or use of the product may cause temporary irritation
to eyes, skin, nose, throat, and upper respiratory tract. Persons subjected to large amounts of this
dust will be forced to leave area because of nuisance conditions such as coughing, sneezing and
nasal irritation. Labored breathing may occur after excessive inhalation. If respiratory symptoms
persist, consult physician. Hydrated lime and sodium hydroxide (caustic soda) are irritating to
respiratory tract and can be damaging to the mucus membrane of the upper respiratory tract.
Eyes
Dust can cause temporary mechanical irritation of eyes. If burning, redness, itching, pain or other
symptoms persist or develop, consult physician. Hydrated lime and sodium hydroxide (caustic soda)
are strongly alkaline materials and is very irritating to eyes. Hydrated lime in various forms is one of
the most common causes of severe chemical burns of the eye, commonly known as “lime burns”. If
burning, redness, itching, pain or other symptoms persist or develop, consult physician.
Skin
Chemical burns or irritation of skin may result due to hydrated lime content. Direct, prolonged or
repeated contact with the skin may cause dermatitis. If skin contact occurs, rinse with water until free
of material, then wash skin thoroughly with mild soap and water. If irritation persists, consult
physician.
Ingestion
May be corrosive to the digestive tract.
CHRONIC:
Inhalation
Exposures to respirable crystalline silica are not expected during the normal use of this product;
however, actual levels must be determined by workplace hygiene testing. Prolonged and repeated
