III. Hazards Identification
Emergency Overview: Hydrated Lime is an odorless white or greyish-white granular powder. Contact
can cause irritation to eyes, skin, respiratory system, and gastrointestinal tract.
Eyes: Contact can cause severe irritation or burning of eyes, including permanent damage.
Contact can cause severe irritation or burning of skin, especially in the presence of
Skin:
moisture.
Ingestion: This product can cause severe irritation or burning of gastro-intestinal tract if swallowed
This product can cause severe irritation of the respiratory system. Long-term exposure
may cause permanent damage. Hydrated Lime is not listed by MSHA, OSHA, or IARC
Inhalation: as a carcinogen, but this product may contain crystalline silica, which has been classified
by IARC as (Group I) carcinogenic to humans when inhaled in the form of quartz or
crystobalite. Inhalation of silica can cause a chronic lung disorder, silicosis.
Medical Conditions Aggravated by Exposure: Contact may aggravate disorders of eyes, skin,
gastrointestinal tract, and respiratory system.
Potential Environmental Effects: This material is alkaline and if released into water or soil will cause and
increase in its pH.
IV. First Aid Measures
Immediately flush eyes with large amounts of water for at least 15 minutes. Pull back the
Eyes:
eyelid to make sure all the lime dust has been washed out.
Skin: Flush exposed area with large amounts of water. Seek medical attention immediately.
Remove to fresh air. Seek medical attention if necessary. If breathing has stopped, give
Inhalation:
artificial respiration.

Use dry methods to collect spilled materials. Evacuate area down
Large Spills: wind of clean-up operations to avoid dust exposure. Store spilled
materials in dry, sealed plastic or metal containers.
For large spills, as much as possible avoid the generation of dusts.
Containment:
Do not release into sewers or waterways.
Residual amounts can be flushed with large amounts of water.
Cleanup: Equipment can be decontaminated by washing with either a mild
vinegar and water solution, or detergent and water solution.
