SECTION 3 - HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW
Hot solder can burn eyes and skin. Fumes during soldering are irritating to eyes and may cause
headache and respiratory system irritation or damage. Prolonged or repeated exposure to rosin
flux fumes during soldering may result in allergic reaction in a sensitive person, resulting in
asthma symptoms.
ECC (Europe) DANGEROUS SUBSTANCES R-PHRASES (Risks to Humans or the Environment):
HAZARD DESIGNATION: R 61 - May cause harm to the unborn child.
R 62 - Possible risk of impaired fertility.
G
Xn Harmful
R 33 - Danger of cumulative effects.
R 36/37/38 - Irritating to eyes, respiratory system and skin.
PRIMARY EXPOSURE:
Fumes during soldering may contain droplets of rosin and/or other organic decomposition products. Skin contact from
handling and decomposition products when heating with soldering iron.
Skin Eyes Inhalation Ingestion
PRIMARY ROUTES OF ENTRY:
TARGET ORGANS:
Flux fumes: eyes, mucous membranes and respiratory system. Ingestion of lead metal can affect kidneys, gastrointestinal,
reproductive and neurological systems.
POTENTIAL HEALTH EFFECTS OF ACUTE (severe short-term) EXPOSURE:
INHALATION: Flux fumes during soldering may cause irritation and damage of mucous membranes and respiratory
system.
EYE CONTACT: Irritation from contact with smoke from soldering.
SKIN CONTACT: Possible local irritation by contact with flux or fumes.
INGESTION: May be harmful if swallowed.
SKIN ABSORPTION: None.
POTENTIAL HEALTH EFFECTS OF CHRONIC (prolonged) EXPOSURE:
Smoke during soldering will contain rosin which is an allergen that can cause eye irritation and respiratory system irritation
and damage. Repeated inhalation or ingestion of lead can result in systemic poisoning.
Medical Conditions Generally Aggravated by Exposure:
Chemical hypersensitivity, asthma and other respiratory conditions, existing eye and skin disorders. Lead: Diseases of the
blood and blood-forming organs, kidneys, nerves and possibly reproductive systems.
CARCINOGENICITY/ NTP OSHA IARC Not Listed
TERATOGENICITY / MUTAGENICITY: See Sections 11 and 15 for additional information.

SECTION 4 - FIRST AID MEASURES
Seek medical assistance for further treatment, observation and support if needed.
EYE CONTACT: For burns flush immediately with cool water and get medical attention. For fume irritation use eye drops and
remove from exposure.
SKIN CONTACT: For burns flush immediately with cool water. If a rash develops from flux fumes, remove person from
exposure and wash skin with soap and water.
INHALATION: Remove person from exposure to fumes.
INGESTION: Not likely to occur.
SECTION 5 - FIRE FIGHTING MEASURES

Extinguishing Means: Water Carbon Dioxide Alcohol Foam Dry Chemical
Hazardous Combustion Products: Carbon monoxide, carbon dioxide. Melted solder above 1000 癋 will liberate toxic lead
and/or antimony fumes.
Explosion Sensitivity: Impact - None Identified Static Discharge Sensitivity: Yes No
Special Firefighting Procedures: Avoid breathing smoke. Wear self-contained breathing apparatus if this material is in the
vicinity of a fire.
Unusual Fire and Explosion Hazards: Flux in cored solder may ignite when the solder melts in a fire.
SECTION 6 - ACCIDENTAL RELEASE MEASURES
Steps to be Taken if Material is Spilled or Released:
Melted solder will solidify on cooling and can be scraped up. Use caution to avoid breathing fumes if a gas torch is used to
cut up large pieces.
SECTION 7 - HANDLING AND STORAGE
Storage Precautions: Exposure to sulfur or to high humidity will tarnish the solder surface.
Handling Precautions: Do not place flux-cored solder into a hot solder pot because the flux may ignite.
Personal Precautions: Avoid breathing smoke / fumes generated during soldering. Wash hands after handling solder before
eating or smoking.

SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION
VENTILATION Provide adequate exhaust ventilation (general and / or local) if necessary to meet exposure requirements.
TO BE USED: Local exhaust ventilation is preferred to minimize dispersion of smoke and fumes into the work area.
Respiratory Protection: When ventilation is not sufficient to remove fumes from the breathing zone, a safety approved respirator
or self-contained breathing apparatus should be worn.
Protective Gloves: Wear rubber or cloth gloves to avoid skin Eye Protection: Safety glasses or goggles should be used.

Other Protective Clothing and Equipment: None.
Hygienic Work Practices: Wash hands thoroughly after handling chemicals or solder containing lead before eating or
smoking.

SECTION 11 - TOXICOLOGICAL INFORMATION
EXPOSURE LIMITS: Not determined for the product. See Section 2 for ingredients.
Lead can accumulate in bone and body organs, and elimination from the body is slow. Medical examinations are advised for
persons repeatedly exposed to levels above the exposure limit for lead. Lead is classified as a Group 2B carcinogen by the
International Agency for Research on Cancer (IARC) and the U.S. Environmental Protection Agency (EPA). Women of child-
bearing age should avoid chronic exposure to lead because of possible effects on reproduction and potential injury to a
developing fetus.
