SECTION 3: HAZARDS IDENTIFICATION
Emergency Overview: Metgrade limestone is an odorless white, grayish-white, red to pink material that ranges
from pebble to a granular powder. Contact can cause irritation to eyes, skin, respiratory
system, and gastrointestinal tract. Metgrade limestone reacts with acid to form CO2.
Potential Health Effects
Eyes: Contact can cause irritation of eyes.
Skin: Contact can cause mild irritation of skin.
Ingestion: This product can cause mild irritation of gastrointestinal tract if swallowed.
Inhalation: This product can cause mild irritation of the respiratory system. Long-term exposure may
cause permanent damage. Metallurgical limestone is not listed by MSHA, OSHA, or IARC
as a carcinogen. However, this product may contain trace amounts of crystalline silica in
the form of quartz or crystobalite, which has been classified by IARC as a Group I
carcinogen to humans when inhaled. Inhalation of silica can also cause a chronic lung
disorder, silicosis.
Medical
Conditions Aggravated
by Exposure: Contact may aggravate disorders of the eyes, skin, gastrointestinal tract, and respiratory
system.
Potential
Environmental Effects: This material is alkaline and if released into water or moist soil will cause an increase in pH.
SECTION 4: FIRST AID MEASURES
Eyes: Immediately flush eyes with generous amounts of water or eye wash solution if water is
unavailable. Pull back eyelid while flushing to ensure that all dust has been washed
out. Seek medical attention promptly if the initial flushing of the eyes does not remove the
irritant. Do not rub eyes.
Skin: Brush off or remove as much dry dust as possible. Wash exposed area with large amounts
of water. If irritation persists, seek medical attention promptly.
Inhalation: Move victim to fresh air. Seek medical attention. If breathing has stopped, give artificial
respiration.
Ingestion: Do not induce vomiting. Seek medical attention immediately. Never give anything by mouth
unless instructed to do so by medical personnel.

SECTION 5: FIRE FIGHTING MEASURES
Fire Hazards: Metgrade Limestone is not combustible or flammable. This product is not considered to be
an explosion hazard, although reaction with incompatible materials, such as acids, may
rupture containers.
Hazardous
Combustion Products: None
Extinguishing Media: Use extinguishing media appropriate for surrounding fire.
Fire
Fighting Instructions: Keep personnel away from and upwind of fire. Avoid skin contact or inhalation of dust. Wear
full fire-fighting turn-out gear (full Bunker gear), and respiratory protection (SCBA).
SECTION 6: ACCIDENTAL RELEASE MEASURES
Spill / Leak Procedures: Use proper protective equipment. Keep away from acids and other incompatible material.
Small Spills: Use dry methods to collect spilled materials. Avoid generating dust. Do not clean up with
compressed air. Store collected materials in dry, sealed plastic or non-aluminum metal
containers. Residue on surfaces may be water washed.
Large Spills: Use dry methods to collect spilled materials. Evacuate area downwind of clean-up
operations to minimize dust exposure. Store spilled materials in dry, sealed plastic or
non-aluminum metal containers.
Containment: Minimize dust generation and prevent bulk release to sewers or waterways.
Clean-up: Residual amounts of material can be flushed with large amounts of water. Equipment can
be washed with either a mild vinegar and water solution, or detergent and water.
SECTION 7: HANDLING AND STORAGE
Handling: Keep in tightly closed plastic or non-aluminum metal containers. Protect containers from
physical damage. Avoid direct skin contact with the material.
Storage: Store in a cool, dry, and well-ventilated location. Do not store near acids or other
incompatible materials. Keep away from moisture. Do not store or ship in aluminum
containers.

SECTION 8: EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering Controls: Provide ventilation adequate to maintain PELs.
Respiratory Protection: Use NIOSH/MSHA approved respirators if airborne concentration exceeds PELs.
Skin Protection: Use appropriate gloves and footwear to prevent skin contact and the potential for irritation.
Clothing should fully cover arms and legs.
Eye Protection: Use safety glasses with side shields or safety goggles. Contact lenses should not be worn
when working with lime products.
Other: Eye wash fountain/stations and emergency showers should be available.

SECTION 11: TOXICOLOGICAL INFORMATION
An LD50 of 6450mg/kg (Rat, oral) has been identified for this product. Metgrade limestone is
not listed by MSHA, OSHA, or IARC as a carcinogen, but this product may contain trace
amounts of crystalline silica, which has been classified by IARC as carcinogenic to
humans when inhaled in the form of quartz or crystobalite.
SECTION 12: ECOLOGICAL INFORMATION
Ecotoxicity: Because of the elevated pH of this product, it would be expected to produce some
ecotoxicity upon exposure to aquatic organisms and aquatic systems in high
concentrations.
Environmental Fate: This material shows no bioaccumulation effect or food chain concentration toxicity.
SECTION 13: DISPOSAL CONSIDERATIONS
Dispose of in accordance with all applicable federal, state, and local environmental
regulations. If this product as supplied, and unmixed, becomes a waste, it will not meet
the criteria of a hazardous waste as defined under the U.S. Resource Conservation and
Recovery Act (RCRA).
SECTION 14: TRANSPORTATION INFORMATION
Metgrade Limestone is not classified as a hazardous material by US DOT and is not
regulated by the Transportation of Dangerous Goods (TDG) when shipped by any mode of
transport.
