Ingestion „
Route of Exposure:
Inhalation
Inhalation of the components of these products are not known to present a significant risk to health
when used according to instructions and with appropriate protective measures (see Section 7). Inhalation of the component/elements has
been reported to cause one or more of the following symptoms/effects upon excessively high and/or prolonged inhalation/exposure.
Acute Exposure: Irritation to the nose, throat, and respiratory tract; cough, nose bleeds, nausea, vomiting, chest tightness, chills, fever,
tearing, pneumonitis, and pulmonary edema.
Chronic Exposure: Abdominal pain and cramps, impaired pulmonary function, liver and kidney damage, and fluorosis (a bone disease
characterized by mottled teeth, osteosclerosis, and pain and loss of mobility in joints).
Route of Exposure
Skin: Can cause irritation, particularly on abraded skin. Prolonged exposure can cause dermatitis.
Eyes: Can cause eye irritation or injury upon prolonged contact.
Ingestion: Some components of these products are potentially toxic if ingested, and may cause one or more of the following symptoms and
effects: nausea, vomiting, diarrhea, abdominal pain, cramps, gastrointestinal irritation, tachychardia, convulsions, and central nervous system
depression.
Miscellaneous Toxicological Information
Carcinogenicity The International Agency for Research on Cancer has reviewed evidence regarding the possible carcinogenicity of fluorides
and has concluded that there is inadequate evidence of carcinogenicity to either humans or animals (IARC, 1987). None of the other
components are classified as potential or demonstrated human carcinogens by IARC, NTP, nor OSHA.
Genetic/Reproductive Effects: Fluorides have been demonstrated to induce mutagenic changes in a number of human and animal cell
cultures. In animal studies, borate compounds have been found to cause decreased sperm production and testicular effects in males, and
developmental effects in foetuses of exposed females. No human reproductive effects attributable to borate compounds have been reported.
Biological Monitoring: The American Conference of Governmental Industrial Hygienists has established Biological Exposure Indices (BEIs)
of 3 mg fluoride per gram (mg/g) of creatinine in urine collected prior to a workshift and 10 mg/g of creatinine in urine collected at the end of
the workshift (ACGIH, 1991).

PREVENTATIVE MEASURES
Personal Protective Equipment: Personal protective equipment will be required when using these materials. The nature of the processing
activity will determine what form of equipment is necessary, i.e., safety glasses, respirator, protective clothing, etc. To maintain exposure
limits below applicable standards, protective equipment should not be substituted for proper handling and engineering controls.
Gloves: Wear appropriate protective gloves when handling pastes, powder or dust to prevent skin contact. When brazing, wear heat
resistant gloves to prevent burns from hot metals or open flame.
Respiratory: Use appropriate ventilation (e.g., dilution, local exhaust) adequate to maintain concentrations of all components and their
decomposition by-products to within their respective ACGIH levels. If an exposure level exceeds an ACGIH level, or other applicable
standard, use a NIOSH-approved respirator having a configuration (class, type of facepiece, filter media, assigned protection factor, etc.)
appropriate to the concentrations of the contaminant(s) generated. For guidance on selection and use of respiratory protection, consult
American National Standard Z 88.2 (ANSI, New York, NY 10036, U.S.A.). All adjacent persons in the immediate vicinity of brazing,
“soldering”, operations shall be similarly protected as necessary by ventilation or approved respirators.
Brazing fluxes are used with metals which, when heated, may emit irritating and/or toxic constituents and/or decomposition products. Consult
the MSDS for the specific brazing alloy and the base metal(s) in use to determine their specific hazards and appropriate protective measures.
Eyes: For powder or dust - safety goggles. When used in brazing, plastic frame safety spectacles with sideshield-filter lens #3 or #4.
Footwear: Refer to workplace safety regulations.
Clothing: Normal clothes for torch brazing or soldering - avoid flammable fabrics.
Other: Practice good housekeeping and personal hygiene procedures. To avoid ingestion, wash hands and face before eating, drinking,
or using cosmetics or tobacco.
Engineering Controls: Adequate ventilation, sinks, showers, and eyewash stations should be provided. The best industrial control practice
is to maintain concentrations of all chemical fumes and dust as low as is practical.
Leak and Spill Procedure: Avoid contact with skin, eyes, or mucous membranes. Dilute and wash spillage with water, avoid high
temperature. Wear appropriate protective equipment (e.g., gloves, boots, impervious goggles) during cleanup and disposal.
Waste Disposal: All effluent ingredients are inorganic. Biodegradability n/Appl. Local regulations may require the removal of fluoride and
suspended trace metals before discharge of final effluent. Chemical precipitation by addition of lime or other calcium compounds, followed by
magnesium hydroxide or aluminum sulfate: then removal of the precipitate by settling and/or filtration has proven simple and effective. The
resulting precipitate containing calcium fluoride and metal carbonates, sulfates or hydroxides should be tested to determine if it is a
hazardous waste, or not. Dispose of through a licensed firm only, at a secure chemical landfill location.
EPA 40CFR, Part 141 - recommended maximum contamination level for primary drinking water is 4 mg/l fluorine.
Handling Procedure and Equipment: Avoid heating above brazing or “soldering” range as excessive fumes may result.
When applicable, use sufficient flux or atmosphere to protect the metals and minimize oxidation/vapourization during use.
Storage Requirements: Store in cool, dry space and avoid storage near incompatible materials (see also Section 5).
Also, avoid conditions which create toxic fumes or dust. Wash exposed skin after handling material.
Special Shipping Information:
HAZARD CLASS: Not hazardous materials or dangerous goods per U.S. DOT / ICAO / IMO / Cdn.TDG.
WHMIS Classification: D1B, D2A, D2B
SECTION 8
FIRST AID MEASURES
Inhalation of the components and decomposition by-products of these products do not pose a significant risk to health when used in
accordance with instructions and appropriate protective measures (see Section 7). The components/decomposition products may cause one
or more of the following symptoms and effects if exposure is excessively high and/or prolonged.
Emergency and First Aid Procedures:
Inhalation: Move victim to fresh air at once. Give oxygen if breathing is laboured, artificial respiration if victim is not breathing.
Keep person warm and quiet. Get medical attention immediately.
Skin: Wash contaminated area with soap and water for at least 5 minutes. Get medical attention if necessary.
Eyes: Wash immediately with large amounts of water, lifting the lower and upper eyelids occasionally for at least 15 minutes. If irritation
continues, get medical attention.
Ingestion: If the subject is conscious, induce vomiting. Seek medical assistance.
If subject is unconscious or convulsive, seek immediate medical attention.

Eyes: Irritation to severe pain. Eye injury with prolonged exposure.
Ingestion: Unlikely with industrial workers. Poisonous and corrosive. Abdominal pain, vomiting, diarrhea, convulsions, collapse.
Obtain medical attention immediately.
Chronic
Inhalation: May result in fluorosis disease.
Skin: Dermatitis.
Eyes: Unlikely.
Ingestion: Unlikely.
Medical Conditions Generally Aggravated By Exposure (see Section 6).
Sources Used: Canadian Centre For Occupational Health And Safety, Hamilton, Ontario; American Welding Society, Miami, Florida;

Additional Information: The information contained herein is only for the manufactured product. The composition and hazards of any
resultant fumes due to heating methods, filler metal alloy, flux and base metals employed may vary significantly.
Brazing fumes consist of various airborne substances which may create hazards to health when they are inhaled or swallowed. The degree
of hazard to the worker(s) in the work area depends upon the composition of the total fume, the concentration of contaminants in the
breathing air and the time-length of exposure to it. It is the responsibility of the user/employer to ensure the suitability of the material use and
that TLV, TWA, and STEL values are not exceeded.
Assessment of the possible exposure to the worker(s) to hazardous fumes, when required, should be carried out by a competent person and
may involve air concentration measurements.
