3. HAZARD IDENTIFICATION
EMERGENCY OVERVIEW: These products consist of odorless, lead/tin alloy wires, which have a metallic luster and may have a
flux core. There are no immediate health hazards associated with these products, as wires. When heated during soldering
operations, these products may generate irritating and toxic fumes of lead oxide, tin oxides, hydrogen chloride, zinc oxides, and
ammonium compounds. There is a danger of cumulative effects if fumes or dusts from these products are inhaled or ingested.
Contact with the rosin core of these wires can result in allergic reaction and sensitization to the skin in susceptible persons. These
products are not reactive. If involved in a fire, these products may generate irritating fumes and a variety of metal oxides, as
described above. Finely divided dusts of these products may result in explosive air/dust mixtures. Emergency responders must wear
personal protective equipment suitable for the situation to which they are responding.
HMIS CLASSIFICATION
HEALTH: 3 (BLUE) FLAMMABILITY: 0 (RED) REACTIVITY: 0 (YELLOW) PROTECTIVE EQUIPMENT: X (USE RESPIRATORY APPARATUS AND
BODY PROTECTION SEE SECTION 8)
SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: During soldering operations, the most significant route of over-exposure is via
inhalation of fumes.
INHALATION: Inhalation of large amounts of particulates generated by these products during soldering operations may be physically irritating and
cause deposits of dust in nasal passages. Due to the presence of lead, inhalation of fumes or dusts from these products can result in lead poisoning.
Symptoms of poisoning include headache, fatigue, nausea, metallic taste in the mouth, abdominal cramps, joint pain, metallic taste in the mouth,
vomiting, constipation, bloody diarrhea, and harmful effects on the central nervous system. Exposure to lead can cause significant cumulative toxic
effects, effects on the reproductive system and may cause cancer. See information under "Other Health Effects" for additional information. When heated
to decomposition, the rosin core of some of these products can include toxic compounds, including formaldehyde, acetaldehyde, or malonaldehyde.
Inhalation of these fumes can result in irritation to the respiratory system.
Exposure to dust or fumes of the Tin components is known to cause a benign pneumoconiosis (stannosis). This form of pneumoconiosis produces
distinctive progressive x-ray changes of the lung as long as exposure persists, but there is no distinctive fibrosis, no evidence of disability, and no special
complicating factors. In addition, inhalation of large amounts of dusts or fumes of these products, can cause metal fume fever. Symptoms of metal fume
fever include flu-like symptoms, metallic taste, fever, sweating, chills, cough, weakness, chest pain, muscle pain, cardiac abnormalities, and increased
white blood cell count. Damage to lungs can occur. Symptoms of metal fume fever can be delayed 24-48 hours. Refer to Section 10 (Stability and
Reactivity) for information on the specific composition of soldering fumes and gases. There is some evidence that inhalation of fumes from the
Ammonium Chloride component of these products may cause respiratory sensitization in susceptible individuals. Symptoms may include difficulty
breathing, persistent coughing and wheezing.
CONTACT WITH SKIN or EYES: Contact of the wire form of these products with the skin is not anticipated to be irritating. Contact with the wire form of
these products can be physically damaging to the eye. Fumes generated during soldering operations can be irritating to the skin and eyes. Symptoms of
skin over-exposure may include irritation and redness; prolonged or repeated skin over-exposures may lead to dermatitis. Contact with the rosin core
can result in allergic reaction and skin sensitization in susceptible individuals. Symptoms could include dermatitis, itching and persistent rash. Contact
with the molten core or wire will burn contaminated skin or eyes.
SKIN ABSORPTION: Skin absorption is not known to be a significant route of over-exposure for any component of these products.
Lead Solders PAGE 2 of 10
INGESTION: Ingestion is not anticipated to be a route of occupational exposure for these products; however, if proper hygiene (e.g. washing of hands)
is not followed during handling and use of these products, ingestion of lead from contamination of the hands can occur, resulting is Lead poisoning.
INJECTION: Though not a likely route of occupational exposure for these products, injection (via punctures or lacerations in the skin) may cause local
reddening, tissue swelling, and discomfort.
OTHER HEALTH EFFECTS: Due to the presence of Lead in these products, exposure to dusts or fumes may result in significant adverse acute and
chronic health effects, as follows. Long-term, low-level lead exposure has resulted in harm to the central nervous system and brain function. Symptoms
of chronic, low to moderate levels include forgetfulness, irritability, tiredness, headache, fatigue, impotence, decreased libido, dizziness, altered mood
states and depression. Symptoms of chronic exposure to moderate to high lead levels include disturbances in hand to eye coordination, reaction times,
visual motor performance, mental performance, gradual decrease in visual acuity with slow recovery or possible blindness, changes in hearing ability,
and in worse cases, encephalopathy (a progressive degeneration of the brain and its functions). Early symptoms of encephalopathy include dullness,
irritability, poor attention span, muscular tremor, headache, and loss of memory and hallucinations. Severe, chronic exposure to Lead at high
concentration can result in symptoms on the central nervous system, including delirium, lack of coordination, convulsions, paralysis, coma and death.
Exposure to Lead can also result in significant adverse results on the peripheral nervous system, including harm to nerves in hands, legs and feet.
These effects can be reversible if exposure is short term (5 months or less) and treatment is received; if not, these effects can become permanent. A
syndrome known as "Lead Palsy" can occur, with symptoms such as weakness of legs or arms, weakness and paralysis of the wrist, fingers and ankles.
At lower exposure levels decreased hand dexterity has been reported. At higher exposure levels an ability to hold the foot or hand in extended position
can occur. Exposure to Lead can also cause adverse effects on the gastrointestinal system, including loss of appetite, inflammation of the stomach
walls (gastritis), colic, severe abdominal pain, cramps, nausea, vomiting, constipation, anorexia, weight loss and decreased urination. In severe cases of
Lead poisoning, a deposit of Lead occurs in the gums near the base of the teeth, resulting in a visible blue-gray line. Reversible kidney injury has been
observed in some cases of workers exposed to Lead at chronic, low to moderate levels. Death due to kidney failure has occurred to workers chronically
exposed to Lead at moderate levels. Exposure to Lead can cause harmful effects to certain types of blood cells, including reduced hemoglobin
production and reduced life-span and function of red blood cells. This harm can cause anemia in workers exposed to moderate levels. Low, moderate
and high level exposure to Lead may increase blood pressure, especially in men. Some studies have indicated that moderate exposure to Lead can
result in electrocardiographic abnormalities. There is some evidence that low-level exposure to Lead can cause harmful effects on the thyroid and
immune systems, including possible susceptibility to colds and flu infections. Exposure to Lead, especially at high levels, has resulted in significant
adverse effects in the reproductive systems of both men and women. Refer to Section 11 (Toxicological Information, Reproductive Toxicity Information)
for additional information.
HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay Terms. Symptoms associated with overexposure to these products and
the fumes generated during soldering operations are as follows:
ACUTE: Inhalation of large amounts of particulates generated by these products during metal processing operations may be physically irritating and
cause deposits of dust in nasal passages. Inhalation of dusts and fumes of these products can cause metal fume fever or irritation of the respiratory
system. Contact with the molten material will burn contaminated skin or eyes. Significant adverse effects on the blood, kidneys, gastrointestinal system,
central and peripheral nervous systems.
CHRONIC: Chronic skin over-exposure to the fumes of these products during soldering operations may produce dermatitis (red, inflamed skin).
Repeated or prolonged over-exposures, via inhalation, to the dusts generated by these products may cause pulmonary fibrosis (scarring of lung tissue).
Chronic inhalation of fumes or dusts of the components of these products, can result in severe, adverse effects on the blood and heart, kidneys, thyroid
and immune systems, and central and periphery nervous system, due to the presence of Lead. Contact with the rosin core of some of these products
can cause an allergic skin reaction and sensitization in susceptible individuals. Due to the presence of the Ammonium Chloride compound in the flux
core of some of these products, inhalation of fumes from soldering may cause allergic respiratory reaction and respiratory sensitization in susceptible
individuals. Due to the Lead component in these products, contact may result in significant adverse effects on the reproductive system. See Section 11
(Toxicological Information) for additional information.
TARGET ORGANS: For fumes: ACUTE: Skin, eyes, respiratory system, blood system, central nervous system, peripheral nervous system,
gastrointestinal system. CHRONIC: Skin, central nervous system, kidneys, heart, blood, central nervous system, thyroid, immune system, reproductive
system.
PART II What should I do if a hazardous situation occurs?
4. FIRST-AID MEASURES
Victims of chemical exposure must be taken for medical attention. Rescuers should be taken for medical attention, if necessary. Take a copy of label
and MSDS to health professional with victim.
SKIN EXPOSURE: If fumes generated by soldering operations involving these products contaminate the skin, begin decontamination with running water.
If molten material contaminates the skin, immediately begin decontamination with cold, running water. Minimum flushing is for 15 minutes. Victim must
seek medical attention if any adverse reaction occurs.
4. FIRST-AID MEASURES (continued)
EYE EXPOSURE: If fumes generated by soldering operations involving these products enter the eyes, open victim's eyes while under gently running
water. Use sufficient force to open eyelids. Have victim "roll" eyes. Minimum flushing is for 15 minutes. Victim must seek immediate medical attention.
INHALATION: If fumes generated by soldering operations involving these products are inhaled, remove victim to fresh air. If necessary, use artificial
respiration to support vital functions.
INGESTION: If swallowed call physician immediately! Do not induce vomiting unless directed by medical personnel. Rinse mouth with water if person is
conscious. Never give fluids or induce vomiting if person is unconscious, having convulsions, or not breathing.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Skin, respiratory, blood, central nervous system and peripheral system, and kidney
disorders, may be aggravated by prolonged over-exposures to the dusts or fumes generated by these products.
RECOMMENDATIONS TO PHYSICIANS: Basic Treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency
and assist ventilations if necessary. Administer oxygen by non-rebreather mask at 10 to 15 L/minutes. Monitor for shock and treat if necessary.
Anticipate seizures and treat if necessary. For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline
during transport. Do not use emetics. For ingestion, rinse mouth and administer 5 mL/kg up to 200 mL of water for dilution if the patient can swallow, has
a strong gag reflex, and does not drool. Administer activated charcoal.
Advanced Treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Use hyperventilation to help
control increased intracranial pressure. Start an IV with lactated Ringer's to support vital signs. For hypotension with signs of hypovolemia, administer
Lead Solders PAGE 3 of 10
fluid cautiously. Watch for signs of fluid overload. Treat seizures with diazepam (Valium). Use proparacaine hydrochloride to assist eye irrigation. The
treatment of lead poisoning is based on the prompt termination of exposure and on the use of chelating agents. The first requirement is categorical. The
second is determined by the severity of poisoning; at present, the greatest issue is whether a symptomatic patients should be treated or not. The most
commonly used therapeutic chelating agents are CaEDTA, BAL, and D-penicillamine can be given. DMSA should also be considered.
5. FIRE-FIGHTING MEASURES
FLASH POINT: Not flammable.
AUTOIGNITION TEMPERATURE: Not applicable for products. Dust clouds of Lead, a possible main component of these products, have a minimum
ignition temperature range
of 270-790癈 (518-1454癋).
FLAMMABLE LIMITS (in air by volume, %):
Lower (LEL): Not applicable.
Upper (UEL): Not applicable.
FIRE EXTINGUISHING MATERIALS: These products are not flammable; use fire-extinguishing agents appropriate for surrounding materials.
Water Spray: YES Carbon Dioxide: YES
Halon: YES Foam: YES
Dry Chemical: YES Other: Any "ABC" Class
UNUSUAL FIRE AND EXPLOSION HAZARDS When involved in a fire, these products may decompose and produce lead oxide, tin oxides, hydrogen
chloride, zinc oxides, and ammonium compounds. The hot material can present a significant thermal hazard to firefighters.
Explosion Sensitivity to Mechanical Impact: Not sensitive.
Explosion Sensitivity to Static Discharge: Although these products are not sensitive
to static discharge, dusts of these products can form explosive air/dust mixtures and can be ignited by static discharge.
SPECIAL FIRE-FIGHTING PROCEDURES: Lead and its decomposition products are hazardous to health. Fire-fighters should not enter an area in
which a fire involves these products without wearing specialized protective equipment suitable for potential Lead exposure. Normal fire-fighter bunker
gear is not adequate to protect against exposure to Lead and its decomposition products. A full-body, encapsulating chemical resistant suit with positive-
pressure Self-Contained Breathing Apparatus may be necessary.
6. ACCIDENTAL RELEASE MEASURES
SPILL AND LEAK RESPONSE: Not Applicable.
PART III How can I prevent hazardous situations from occurring?
7. HANDLING AND STORAGE
WORK PRACTICES AND HYGIENE PRACTICES: As with all chemicals, avoid getting these products ON YOU or IN YOU. Wash thoroughly after
handling these products. Do not eat or drink while handling these products. Use ventilation and other engineering controls to minimize potential
exposure to these products. If dusts or fumes of these products are present, use of a suitable NIOSH approved respirator must commence immediately
to protect against possible Lead poisoning. Unprotected workers must avoid all contact with these products.
STORAGE AND HANDLING PRACTICES: All employees who handle these products should be trained to handle it safely, following the requirements of
the OSHA Lead Standard (29 CFR 1910.1025). Use in clearly posted areas(s) indicating Lead hazard. Access doors must remain closed while these
products are being used or stored. When handling Lead powder on a large scale, closed-handling systems for processes should be used. If this is not
possible, use in the smallest possible amounts in appropriate labeled, containment devices (e.g. fume hood). Containment devices should be made of
smooth, unbreakable compatible material. Maintain containment devices at appropriate air-flow and negative pressure. Check regularly. Use in a well-
ventilated location. Avoid the generation of dusts and prevent the release of fumes to the workplace. Avoid breathing fumes of these products generated
during soldering operations. Open containers on a stable surface. Cover surfaces in which these products are being used with compatible, chemical
resistant and/or disposable material for easier containment and clean-up. Good housekeeping is very important. Keep work areas clean. Packages of
these products must be properly labeled. When these products are used during soldering operations, follow the requirements of the Federal
Occupational Safety and Health Welding and Cutting Standard (29 CFR 1910 Subpart Q) and the safety standards of the American National Standards
Institute for welding and cutting (ANSI Z49.1). Store packages in a cool, dry location. Store away from incompatible materials (see Section 10, Stability
and Reactivity).
PROTECTIVE PRACTICES DURING MAINTENANCE OF CONTAMINATED EQUIPMENT: Not applicable.
8. EXPOSURE CONTROLS - PERSONAL PROTECTION
VENTILATION AND ENGINEERING CONTROLS: As per the OSHA Lead Standard, 29 CFR 1910.1025, the employer shall assure that no employee is
exposed to Lead at concentrations greater than 50 g/cubic meter averaged over an 8-hour period. If an employee is exposed to Lead for more than 8
hours in any work day, the permissible exposure limit, as a TWA for that day, shall be reduced according to the following formula: Maximum permissible
limit (in g/cubic meter) = 400 divided by the number of hours worked in the day. Use with adequate ventilation to ensure exposure levels are
maintained below these limits and the limits for Lead and other components of these products provided in Section 2 (Composition and Information on
Ingredients). Prudent practice is to ensure eyewash/safety shower stations are available near areas where these products are used.
RESPIRATORY PROTECTION: Maintain airborne contaminant concentrations below guidelines listed in Section 2 (Composition and Information on
Ingredients). If respiratory protection is needed (i.e. a Weld Fume Respirator, or Air-Line Respirator for welding in confined spaces), U.S. Federal OSHA
Standard (29 CFR 1910.134), applicable U.S. State regulations, or the Canadian CSA Standard Z94.4-93 and applicable standards of Canadian
Provinces. Respiratory Protection is recommended to be worn during welding operations. Oxygen levels below 19.5% are considered IDLH by OSHA. In
such atmospheres, use of a full-facepiece pressure/demand SCBA or a full facepiece, supplied air respirator with auxiliary self-contained air supply is
required under OSHA's Respiratory Protection Standard (1910.134-1998). The following are NIOSH recommendations for respirator selection for
Ammonium Chloride, Lead, Welding fumes, Rosin Core, Pyrolysis Products, Tin and Zinc Chloride, and are provided for additional information:

The following information is for the products:
APPEARANCE AND COLOR: These odorless products consist of tin/lead alloy with a metallic lust and may have a flux core.
10. STABILITY AND REACTIVITY
STABILITY: Normally stable. These products can oxidize rapidly to form an insoluble layer of basic lead carbonate.
DECOMPOSITION PRODUCTS: Lead oxide, tin oxides, hydrogen chloride, zinc oxides, and ammonium compounds.
NOTE: The composition and quality of soldering fumes and gases are dependent upon the metal being soldered, the process, the procedure, and the
alloys used. Other conditions that could also influence the composition and quantity of fumes and gases to which workers may be exposed include the
following: any coatings on metal being welded (e.g. paint, plating, or galvanizing), the number of work stations and the volume of the work area, the
quality of ventilation, the position of the work stations with respect to the fume plume, and the presence of other contaminates in the atmosphere. When
the alloy is consumed, the fume and gas decomposition products generated are different in percent and form from the ingredients listed in Section 2
(Composition and Information on Ingredients). Fume and gas decomposition products, and not the ingredients in the solders, are important.
Concentration of the given fume or gas component may decrease or increase by many times the original concentration. New compounds may form.
Decomposition products of normal operations include not only those originating from volatilization, reaction, or oxidation of the product's components but
also those from base metals and any coating (as noted previously). The best method to determine the actual composition of generated fumes and gases
is to take an air sample from the breathing zone. For additional information, refer to the American Welding Society Publication, "Fumes and Gases in the
Welding Environment".
MATERIALS WITH THESE PRODUCTS ARE INCOMPATIBLE: These products will be attacked or can react with strong acids, strong bases, hydrogen
peroxide (52% or greater- in presence of manganese dioxide), sodium azide, ammonium nitrate, sodium acetylides, sodium carbide, zirconium, or
chlorine trifluoride. The flux or rosin core of these products are incompatible with potassium, strong acids, alkalis, interhalogens, strong oxidizers,
ammonium nitrate, hydrogen cyanide, potassium chlorate and lead salts (not lead metal) and silver salts.

SUSPECTED CANCER AGENT: Components of these products are listed as follows:
LEAD: ACGIH TLV-A3 (Confirmed Animal Carcinogen), EPA-B2 (Probable Human Carcinogen - Sufficient Evidence from Animal Studies;
inadequate evidence or no data from epidemiologic studies); IARC-2B (Possibly Carcinogenic to Humans)
ZINC CHLORIDE: EPA-D [dusts & mists] (Not Classifiable as to Human Carcinogenicity)
The other components of this product are not found on the following lists: FEDERAL OSHA Z LIST, NTP, IARC, and CAL/OSHA and therefore are not
considered to be, nor suspected to be, cancer-causing agents by these agencies.
IRRITANCY OF PRODUCT: Dusts or fumes of these products may be irritating to contaminated skin and eyes. Fumes may be irritating to the
respiratory system.
SENSITIZATION TO THE PRODUCT: There is some evidence that inhalation of fumes from the Ammonium Chloride component of some of these
products may cause respiratory sensitization in susceptible individuals. Symptoms may include difficulty breathing, persistent coughing and wheezing.
Contact with the rosin core can result in allergic reaction and skin sensitization in susceptible individuals.

REPRODUCTIVE TOXICITY INFORMATION: Listed below is information concerning the effects of these products and their components on the human
reproductive system.
Mutagenicity: These products are not reported to produce mutagenic effects in humans. Cytogenic analysis studies of human cells (cell type
and duration of exposure unreported) have produced positive results at a level of 50 g/mL. In vitro assays of human lymphocytes indicate
that the Zinc Chloride may cause chromosomal aberrations. In animal studies, positive mutagenic results (chromosome aberrations) have
been reported in rats, mice and monkeys exposed orally to the Lead component of these products. Positive results were obtained in
chromosomal aberrations tests involving the Ammonium Chloride component of these products using cultured Chinese hamster fibroblast
cells, with no metabolic agitation.
Embryotoxicity: These products are not reported to produce embryotoxic effects in humans. There is evidence that high Lead levels in human
mother's blood can significantly increase the risk of spontaneous abortions. The Lead, and Zinc Chloride components of these products have
produced embryotoxic effects in animal studies.
Teratogenicity: These products are not reported to cause teratogenic effects in humans. Lead has an adverse effect on human fetuses,
particularly in the later stages of development. Distribution of lead in fetal tissues was examined in a case in which a woman was exposed
during pregnancy. The female worker was exposed to lead dust for 8 hours daily when conception occurred. Measurements of Lead content
were started after the end of the exposure and continued for 6 months until normal values were obtained. Because of half-life of nearly 20
days for lead elimination from blood, the estimated body burden at the end of exposure was about 1200 ppb. The fetal tissue samples
contained between 0.4 (brain) and 7.9 (liver) g Pb/grams dry weight. The fetal lead was stored mainly in bone, blood, and liver. The Lead
component of this product has produced teratogenic effects in animal studies.
Reproductive Toxicity: These products are not reported to cause reproductive effects in humans; however, the Lead component of this product
has produced embryotoxic effects in humans. There is convincing evidence that Lead is transferred to neonates via maternal milk. It appears
that maternal milk might be a source of Lead for the neonates, particularly when metal levels are elevated in the mother. Chronic exposure to
Lead in human males has been found to produce infertility, germinal epithelium damage, oligospermia and testicular degeneration, decreased
sperm motility, and prostatic hyperplasia. The Lead component of this product has produced reproductive effects in animal studies. Injections
of the Zinc Chloride component of these products has produced testicular tumors in animal tests.
A mutagen is a chemical, which causes permanent changes to genetic material (DNA) such that the changes will propagate through generational lines.
An embryotoxin is a chemical, which causes damage to a developing embryo (i.e. within the first eight weeks of pregnancy in humans), but the damage
does not propagate across generational lines. A teratogen is a chemical, which causes damage to a developing fetus, but the damage does not
propagate across generational lines. A reproductive toxin is any substance, which interferes in any way with the reproductive process.
BIOLOGICAL EXPOSURE INDICES: The following BEIs are applicable to the Lead component of these products.
CHEMICAL DETERMINANT SAMPLING TIME BEI
?Lead in blood ?not critical ?30 g/100 mL
Note: Women of child-bearing potential, whose blood Pb exceeds10g/dl,
are at risk of delivering a child with a blood Pb over the current Centers for
Disease control guideline of 10g/dl. If the blood Pb of such children remains
elevated, they may be at increased risk of cognitive deficits. The blood Pb of
these children should be closely monitored and appropriate steps should be
taken to minimize the child's exposure to environmental Lead
12. ECOLOGICAL INFORMATION
ALL WORK PRACTICES MUST BE AIMED AT ELIMINATING ENVIRONMENTAL CONTAMINATION.
ENVIRONMENTAL STABILITY: Components of these products will react with water and air to form a variety of stable metal oxides.
EFFECT OF MATERIAL ON PLANTS or ANIMALS: Due to the Lead component, adverse effect may occur to animals which come into contact with
these products. No data is available on the components of these products and plants.
EFFECT OF CHEMICAL ON AQUATIC LIFE: Due to the Lead component of these products, a release of product to an aquatic environment may have
a significant adverse effect.
