SECTION 3 HAZARD IDENTIFICATION (continued)
POTENTIAL HEALTH EFFECTS
ACUTE (continued):
Skin: Prolonged or repeated exposure may cause skin irritation, even a burn. May cause more severe response if skin
is abraded (scratched or cut). Not classified as corrosive to the skin according to DOT guidelines. A single prolonged
exposure is not likely to result in the material being absorbed through skin in harmful amounts. Skin exposure to
formaldehyde may cause skin or sensitization (allergy).
Inhalation: : Inhalation of vapors or mists from this product may irritate the nose, throat, lungs, and upper respiratory
tract. Single exposure to vapors is not expected to pose a hazard; vapors are primarily water. Mists may cause irritation
of upper respiratory tract. Formaldehyde gas, which can cause severe respiratory irritation, may be released under
conditions of high heat and humidity. Inhalation of formaldehyde may result in discomfort such as nausea, headache, or
weakness; upper respiratory tract (nose and throat) irritation marked by mild burning sensation, sore and dry throats,
and thirst; and temporary lung irritation effects with cough, discomfort, difficulty in breathing, and shortness of breath. In
a few rare instances, respiratory tract sensitization (asthma) has been reported in individuals exposed to formaldehyde.
Ingestion: Single dose oral toxicity is considered to be low. Small amounts swallowed incidental to normal handling
operations are not likely to cause injury; swallowing larger amounts may cause injury. Ingestion may cause
gastrointestinal irritation or ulceration. Ingestion may cause burns of mouth and throat.
CHRONIC:
Formaldehyde is present in very small quantities. Formaldehyde can be readily detected due to its irritant properties.
The odor detection level varies among different individuals between 0.2 to 1 ppm. Also, acclimation can occur from
repeated exposure but sensitivity returns following rest periods away from the atmosphere containing formaldehyde.
Whether a risk exists at levels below the odor threshold has not been determined.
This product contains raw materials that contain trace amounts of potentially hazardous ingredients including trisodium
salt of nitrilotriacetic acid. At levels present in product, trisodium salt of nitrilotriacetic acid does not pose any known risk
to human health. For more information see Section 11 Toxicological Information.
Has caused birth defects in laboratory animals at doses toxic to the mother. Has been toxic to the fetus in laboratory
animals at doses non-toxic to the mother. These effects may be associated with zinc deficiency due to chelation. Birth
defects are unlikely at typical use concentrations. Test results have shown formaldehyde to cause cancer in laboratory
animals.
TARGET ORGANS: Eyes, skin and respiratory system.
PRIMARY ROUTES OF ENTRY: Inhalation, eyes and skin contact.
SECTION 4
FIRST AID MEASURES
FIRST AID PROCEDURES
Eyes: It is imperative to immediately flush thoroughly with water for 30 minutes. Prompt medical attention is critical.
Skin: Wash with mild soap and water.
Inhalation: Remove subject to fresh air. Leave the area of fume/vapor exposure and remain away until coughing and
other symptoms subside. If respiratory symptoms persist (irritation, cough, nausea, dizziness, etc.), consult physician.
Ingestion: Do not induce vomiting. Give large amounts of water or milk if available and transport to a medical facility.
Notes to Physician: May cause tissue destruction leading to stricture. If lavage is performed, suggest endotracheal
and/or esophagoscopic control. If burn is present, treat as any thermal burn, after decontamination. No specific
antidote. Supportive care. Treatment based on judgement of the physician in response to reactions of the patient.

SECTION 8
EXPOSURE CONTROLS / PERSONAL PROTECTION
ENGINEERING CONTROLS:
Provide ventilation sufficient to control airborne levels.
If user operations such as mixing, sanding or grinding generate airborne dust, use ventilation to keep dust
concentrations below permissible exposure limits (See Section 2).
Where general ventilation is inadequate, use process enclosures, local exhaust ventilation, or other engineering controls
to control dust levels below permissible exposure limits (see Section 2). If engineering controls are not possible, wear a
properly fitted NIOSH/MSHA-approved particulate respirator.
Facilities storing or using this material should be equipped with an adequate number of eyewash facilities and safety
showers.
RESPIRATORY PROTECTION:
Avoid inhalation of mist or vapors. Provide general ventilation and local exhaust ventilation to meet TLV requirements of
individual ingredients and to control misty/vapor conditions. Avoid creating vapors or mist. Wear a NIOSH/MSHA-
approved organic vapor/mist respirator in poorly ventilated areas, if TLV is exceeded, and/or when misty conditions exist
as appropriate.
OTHER PERSONAL PROTECTIVE EQUIPMENT:
Eye/Face: Wear eye protection (faceshield, safety glasses with side shields, chemical goggles). Eye wash fountain
should be located in immediate work area.
Skin: When prolonged or frequently repeated contact could occur, use protective clothing impervious to this material.
Selection of specific items such as faceshield, gloves, boots, apron, or full-body suit will depend on operation. If hands
are cut or scratched, use gloves impervious to this material even for brief exposures.

TOXICOLOGICAL INFORMATION
ACUTE EFFECTS:
LD50: Oral LD50(Rat) : >2000mg/kg
CHRONIC EFFECTS / CARCINOGENICITY:
Trisodium Nitrilotriacetate: Trisodium Nitrilotriacetate (5064-31-3): At levels present in product, trisodium salt of
nitrilotriacetic acid does not pose any known risk to human health. This mixture contains a very small amount of
trisodium salt of nitrilotriacetic acid (<0.0024 weight %). Large dietary doses of trisodium nitriloacetate have caused
urinary tumors in laboratory animals, lower doses did not induce significant numbers of such lesions. Evidence for this
development in humans has never been found. Trisodium salt of nitrilotriacetic acid is classified as a possible human
carcinogen (Group 2B) by the International Agency for Research on Cancer (IARC). [ACGIH TLV: Not Established,
OSHA PEL: Not Established]
Has caused birth defects in laboratory animals at doses toxic to the mother. Has been toxic to the fetus in laboratory
animals at doses non-toxic to the mother. These effects may be associated with zinc deficiency due to chelation. Birth
defects are unlikely at typical use concentrations. Test results have shown formaldehyde to cause cancer in laboratory
animals.
Formaldehyde: Formaldehyde gas has been related to the development of nasal tumors in some experimental animals.
Formaldehyde is classified as a human carcinogen (Group 1) by the International Agency for Research on Cancer
(IARC). Long time exposure to formaldehyde may cause skin or respiratory sensitization.
SECTION 12
ECOLOGICAL INFORMATION
ENVIRONMENTAL TOXICITY:
Movement and Partitioning: No bioconcentration is expected because of the relatively high water solubility. Log
octanol/water partition coefficient (log Pow) is estimated using a structural fragment method to be 鈥?7.453 (for the acid).
Degradation and Persistence: Biodegradation under aerobic laboratory conditions is below detectable limits (2.5%).
Theoretical oxygen demand (ThOD) is calculated to be 1.18 p/p.
Ecotoxicity Values:
Material is practically non-toxic to aquatic organisms on an acute basis (LC50 /EC50 > 100 mg/L in most sensitive
species).
Acute LC50 in bluegill (Lepomis macrochirus): 1115 mg/L based largely or completely on information for
diethylenetriamine pentaacetic acid.
Acute LC50 in water flea Daphnia magna: >100 mg/L.
Acute LC50 in fathead minnow (Pimephales promelas): >300 mg/L.
