3. HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
*************************************************************
White Crystals. Odorless. Causes Eye Irritation. May Be Harmful if
Swallowed. Isolate Area.
*************************************************************
POTENTIAL HEALTH EFFECTS: (See Section 11 for toxicological data.)
EYE: May cause pain disproportionate to level of irritation to eye tissues. May cause
moderate eye irritation which may be slow to heal. May cause slight temporary corneal
damage.
SKIN: Essentially non-irritating to skin. Prolonged skin contact is unlikely to result in
absorption of harmful amounts.
INGESTION: Low toxicity if swallowed. Small amounts swallowed incidental to normal
handling operations are not likely to cause injury; however, swallowing larger amounts may
cause injury.
INHALATION: Vapors are unlikely due to physical properties. No adverse effects are
anticipated from single exposure to dust.

SYSTEMIC (other target organ) EFFECTS: Based on available data, repeated exposures
are not anticipated to cause additional significant adverse effects.
CANCER INFORMATION: This mixture contains a very small amount of the trisodium salt of
nitrilotriacetic acid (trisodium NTA, CAS# 005064-31-3) which is listed as a potential
carcinogen for hazard communication purposes under OSHA Standard CFR 1910.01200.
Components listed by IARC and NTP: trisodium nitrilotriacetate. Although large dietary
doses of NTA have caused urinary tumors in laboratory animals, there is little likelihood that
NTA could cause cancer in humans, especially at subtoxic doses. The trisodium salt of EDTA
did not cause cancer in laboratory animals.
TERATOLOGY (birth defects): EDTA and it’s sodium salts have been reported to cause
birth defects in laboratory animals only at exaggerated doses that were toxic to the mother.
These effects are likely associated with zinc deficiency due to chelation. Birth defects are
unlikely. Exposures having no effect on the mother should have no effect on the fetus.
REPRODUCTIVE EFFECTS: Limited data in laboratory animals suggest that the material
does not effect reproduction.
___________________________________________________________________
4. FIRST AID
EYE: Immediately flush eyes with water; remove contact lenses, if present, after the first 5
minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention
without delay, preferably from an ophthalmologist.
SKIN: Wash skin with plenty of water.
INGESTION: IF swallowed, seek medical attention. Do not induce vomiting unless directed
by medical personnel.
INHALATION: Move person to fresh air; if effects occur, consult a physician.
NOTE TO PHYSICIAN: No specific antidote. Treatment of exposure should be directed at
the control of symptoms and the clinical condition of the patient.

FLAMMABLE PROPERTIES
FLASH POINT: N/A
METHOD — USED: N/A
AUTOIGNITION TEMPERATURE: N/A
FLAMMABILITY LIMITS
LFL: N/A
UFL: N/A
HAZARDOUS COMBUSTION PRODUCTS: Fire conditions may cause this product to
decompose. Refer to “ Hazardous Decomposition Section”.
OTHER FLAMMABILITY INFORMATION: Pneumatic conveying and other mechanical
handling operations can generate combustible dust. To reduce the potential for dust
explosions, do not permit dust to accumulate.
EXTINGUISHING MEDIA: This material does not burn. If exposed to fire from another
source, use suitable extinguishing agent for that fire.
FIRE FIGHTING INSTRUCTIONS: Keep people away. Isolate fire area and deny

unnecessary entry. Hand held dry chemical or carbon dioxide extinguishers may be used for
small fires. Processing this product may generate dusts. Dust explosion hazard may result
from forceful application of fire extinguishing agents.
PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS: Wear positive-pressure self-contained
breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet,
coat, pants, boots, and gloves). If protective equipment is not available or not used, fight fire
from a protected location or safe distance.
___________________________________________________________________
6. ACCIDENTAL RELEASE MEASURES (see Section 15 for Regulatory info)
Protect People: Isolate area. Keep unnecessary and unprotected personnel from entering
the area. Refer to Section 7, Handling for additional precautionary measures. Use
appropriate safety equipment. For additional information, refer to Section 8, Exposure
Controls/Personal Protection.
PROTECT THE ENVIRONMENT: Prevent from entering into soil, ditches, sewers,
waterways, and or groundwater. See Section 12, Ecological Information.
CLEAN UP: Contain spilled material if possible. Sweep up. Collect in suitable and properly
labeled containers. See Section 13, Disposal Considerations for additional information.
___________________________________________________________________
7. HANDLING AND STORAGE
HANDLING: Avoid contact with eyes. Do not swallow. Wash thoroughly after handling.
Good housekeeping and controlling of dusts are necessary for safe handling of product.
STORAGE: Store below 50C (120F). Do not store in : zinc, aluminum, carbon steel, copper,
copper alloys or nickel.
___________________________________________________________________
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
ENGINEERING CONTROLS: Good ventilation should be sufficient for most conditions.
Local exhaust ventilation may be necessary for some operations.
PERSONAL PROTECTIVE EQUIPMENT:
EYE/FACE PROTECTION: Use chemical glasses.
SKIN PROTECTION: No precautions other than clean body-covering clothing should be
needed.
RESPIRATORY PROTECTION: In dusty or misty atmospheres, use an approved particulate
respirator.
EXPOSURE GUIDELINES: None Established.

10. STABILITY AND REACTIVITY:
CHEMICAL STABILITY: Stable under recommended storage conditions. See Storage,
Section 7.
CONDITIONS TO AVOID: Exposure to elevated temperatures can cause product to
decompose.
INCOMPATIBILITY WITH OTHER MATERIALS: Avoid contact with: oxidizers. Flammable
hydrogen may be generated from contact with metals such as aluminum.
HAZARDOUS DECOMPOSITION PRODUCTS: Decomposition products depend upon
temperature, air supply and the presence of other materials. Decomposition products can
include and are not limited to carbon monoxide, carbon dioxide, ammonia, nitrogen oxides.
HAZARDOUS POLYMERIZATION: Will not occur.

11. TOXICOLIGICAL INFORMATION: (See Section 3 for potential health effects. For
detailed toxicological data, write or call the address or non-emergency number shown
in Section 1.
SKIN: The dermal LD50 has not been determined.
INGESTION: The oral LD50 for rats is between 630-1260 mg/kg.
MUTAGENICITY: Most data indicate that EDTA and it’s salts are not mutagenic. Minimal
effects reported are likely due to trace metal deficiencies resulting from chelation by EDTA.
