                       SECTION III (POTENTIAL HEALTH EFFECTS AND HEALTH HAZARD DATA)

Target organ statement:

DANGER: Causes severe burns to skin, eyes, and respiratory system. May be fatal if swallowed or inhaled. WELDING FUMES (not

otherwise specified) are considered to be carcinogenic defined with no further categorization by NIOSH and IARC.



SHORT TERM (ACUTE) OVEREXPOSURE TO PASTE:

Swallowing       May cause burns of mouth and throat.

Inhalation       Irritation to respiratory system. Coughing and sneezing. Existing lung disorders will be aggravated.

                 Severe exposure may cause pulmonary edema. Metal fume fever may result from inhaling zinc oxide,

                 which is a possible decomposition product at high temperatures.

Skin Contact     Dermatitis, possible chemical burns, and corrosive to skin. Existing disorders will be aggravated.

Eye Contact      Irritation to the eyes, tearing, burn of the eye surfaces, corrosive to the eyes, may cause blindness.



FLUORIDES - Short-term exposure to fluoride compounds produced may cause eye and skin burns, and pulmonary edema bronchitis.

Exposure to extremely high levels of fluorides can cause abdominal pain, diarrhea, muscular weakness, and convulsions. In extreme cases it

can cause loss of consciousness and death.



ETHYLENE GLYCOL: Symptoms to overexposure to ethylene glycol include irritation to eyes, skin, nose, throat, nausea vomiting,

abdominal pain, lassitude (weakness, exhaustion), dizziness, stupor, convulsions, central nervous system, depression, and skin sensitization.

Renal failure and brain injury may result.

LONG TERM (CHRONIC) OVEREXPOSURE: FLUORIDES - Overexposure to fluorides can cause serious bone erosion, excessive

calcification of the bone and calcification of the ribs, pelvis and spinal column. May cause skin rash. ETHYLENE GLYCOL: Long term

overexposure to ethylene glycol may effect the central nervous system and eyes. EXPOSURE TO FLUX: Contact burns, irritation to skin

(scarring), eyes, and respiratory system. Possible liver and kidney effects.





                                      SECTION IV (EMERGENCY AND FIRST AID PROCEDURES)

Swallowing:      Call a physician at once or your poison control center. Advise of Section II immediately. May be fatal. Corrosive

                 to mucous membranes.

Skin:            Promptly flush with water for 15 minutes to remove all residue. If rash or burn develops, consult a physician. Material is

                 corrosive. Remove contaminated clothing and shoes. Wash contaminated clothing before reuse.

Inhalation:      Remove to fresh air. If fumes are inhaled, call a physician.

Eyes:            Flush with water for at least 15 minutes to remove all residue. Hold eyelids apart during irrigation. Get immediate medical

                 help - blindness may result.





                                              SECTION V (FIRE AND EXPLOSION DATA)



Flashpoint: Will not burn.

Extinguishing media: water, fog, or foam

Special fire fighting procedures: full protective equipment required. May release zinc oxide and zinc chloride.

                                                   SECTION VI (REACTIVITY DATA)



Stability consideration: stable

Hazardous polymerization: will not occur

Conditions to avoid: none

Incompatibility: Materials to avoid: Cyanide - may release toxic HCN        Sulfide - may release toxic hydrogen sulfide

Hazardous combustion or decompositions products: zinc oxide.



                                             SECTION VII (SPILL AND LEAK RESPONSE)



Steps to be taken if material is released or spilled: Contain spill, absorb, sweep up and dispose. Flush area to chemical sewer.

                                       SECTION VIII (SPECIAL PROTECTION INFORMATION)



Respiratory protection: If the workstation is not properly ventilated to exhaust all fumes and vapors, use a NIOSH approved mask. Monitor

fume levels.

Ventilation: Maintain airflow away from the user to remove all fumes and vapors, so that the PEL is never exceeded. Adhere to

environmental regulations for exhausts.

Protective gloves: Rubber gloves.

Eye protection: Chemical safety goggles.

Other protective equipment: Full protective equipment normally used in soldering operation so as to prevent any contact. Review operations

   to avoid contact with hazardous gas, liquid, or solid. See also:

                                SECTION IX (STORAGE, HANDLING AND SPECIAL PRECAUTIONS)



Precautions to be taken in handling and storage: Store 157 flux at ambient conditions. Store in original container. Wash thoroughly after

handling to remove all residue.

Other precautions: Do NOT breathe fumes. Professionally wash contaminated clothing before reuse. Existing lung disorders will have

increased toxic susceptibility.
