Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:NO IARC:YES OSHA:NO
Health Hazards Acute and Chronic:EXPOSURE LIMITS: NOT DETERMINED FOR
PRODUCT. PRIMARY EXPOSURE DURING SOLDERING IS TO EVAPORATED SOLVENT
WHICH MAY CONTAIN DROPLETS OF ROSIN AND/OR ORGANIC DECOMPOSITION
PRODUCTS. TARGET ORGANS: FLUX F UMES: EYES, SKIN, MUCOUS MEMBRANES
AND RESPIRATORY SYSTEM. INGESTION OF LEAD METAL CAN AFFECT KIDNEYS,
GASTROINTESTINAL, REPRODUCTIVE & NEUROLOGICAL SYSTEMS. EFFECTS OF
ACUTE (SEVERE SHORT-TERM) EXPO SURE: INHALATION: FLUX FUMES DURING
SOLDERING MAY CAUSE IRRIT & DAMAGE OF MUC MEMB & RESP SYSTEM. SKIN
CONTACT: POSSIBLE LOCAL IRRITATION. SKIN ABSORPTION: NONE. EYE
CONTACT: IRRITATION FROM CONTACT WITH (SIGNS & SYMPTOMS OF
OVEREXPOSURE)
Explanation of Carcinogenicity:LEAD: IARC HAS PLACED LEAD AND ITS
COMPOUNDS IN CLASS 2B, POSSIBLY CARCINOGENIC TO HUMANS (SUPPLEMENT
7, PAGE 230, 1987 - ). LEAD AND ITS COMPOUNDS HAVE BEEN PLACED IN
CLASS B2, PROBABLY CARCINOGE NIC TO HUMANS BY USEPA.
Effects of Overexposure:HEALTH HAZARDS ACUTE AND CHRONIC (CONT): SMOKE
WHILE SOLDERING. INGESTION: MOST OF SOLDERPASTE WILL PASS THROUGH
THE BODY UNABSORBED. LEAD THAT IS ABSORBED IS CAUGHT BY THE LIVER
AND, IN PART, EXCRETE D IN THE BILE. EFFECTS OF CHRONIC
(PROLONGED) EXPOSURE: PROLONGED OR REPEATED SKIN CONTACT CAN RESULT
IN RASH. BREATHING FUMES DURING SOLDERING MAY CAUSE RESPIRATORY
SYSTEM IRRITATION, HEADACHE AND I RRITATION OF MUCOUS MEMBRANES.
SMOKE DURING SOLDERING WILL CONTAIN ROSIN WHICH IS AN ALLERGEN AND
CAN CUASE RESPIRATORY SYSTEM IRRITATION AND DAMAGE. REPEATED
INGESTION OF LEAD CAN RESULT IN SYSTEMIC POISONING.
Medical Cond Aggravated by Exposure:FLUX: PRE-EXISTING CONDITIONS OF
THE LUNGS. LEAD: DISEASES OF BLOOD/BLOOD-FORMING ORGANS, KIDNEYS,
NERVES & POSSIBLY REPRODUCTIVE SYSTEM.

First Aid:SEEK MEDICAL ASSISTANCE FOR FURTHER TREATMENT, OBSERVATION
AND SUPPORT, IF NEEDED. EYES: FLUSH WITH PLENTY OF WATER AND GET
MEDICAL ATTENTION. SKIN CONTACT: WASH THOROUGHLY WITH SOAP AND
WATER. INHALA TION: REMOVE VICTIM TO FRESH AIR. INGESTION: GASTRIC
LAVAGE (STOMACH PUMPING) IF PHYSICIAN ADVISES. GET PROMPT MEDICAL
ATTENTION.
