ENGINEERING CONTROLS: Proper ventilation must be maintained.
VENTILATION: Use enough ventilation, local exhaust at the spray area, or both, to keep the fumes and gases below the TLV's in
the workers breathing and the general area. Train the worker to keep his head out of the fumes. Monitor fume levels and do not
exceed permissible exposure limits or values.
RESPIRATORY PROTECTION: Do NOT breathe fumes. Use respirable fume respirator or air supplied respirator when brazing
in a confined space or where local exhaust or ventilation does not keep exposure below the TLV's.
EYE PROTECTION: Wear safety glasses with side shields, face shield, and/or goggles to protect against airborne dust.
PROTECTIVE CLOTHING: Wear gloves when using or prolonged contact with skin or repeated contact with skin is likely.
Wear hand and body protection to prevent injury. See ANSI Z49.1.
OTHER PROTECTIVE EQUIPMENT: Full protective equipment normally used in soldering / brazing operation so as to prevent
any contact. Review operations to avoid contact with hazardous gas, liquid, or solid. See also:
29CFR 1910.132 - 29 CFR 1910.140 Personal Protective Equipment
29 CFR 1910.251 - 29 CFR 1910.257 Welding, Cutting and Brazing
SKIN PROTECTION: Individuals having sensitive skin may find it beneficial to use a barrier cream or moisturizer when
excessive or prolonged contact with skin is likely.
WORK HYGIENIC PRACTICES: Professionally wash contaminated clothing before re-use. Food and drink should not be
consumed or tobacco products used, nor cosmetics applied in area where metal exposures are possible.
EXPOSURE GUIDELINES: Use industrial hygiene monitoring equipment to ensure that exposure does not exceed applicable
national exposure limits.
EFFECTS OF OVEREXPOSURE
- brazing may create one or more of the following health hazards:
FUMES AND GASES can be dangerous to your health.
PRIMARY ROUTES OF ENTRY are the respiratory system. Other possible routes are eyes and/or skin contact.
PREEXISTING respiratory or allergic conditions may be aggravated in some individuals (i.e. asthma, emphysema).
Brazing fumes cannot be classified simply. The composition and quantity of both are dependent upon the metal being brazed, the
process, procedure, and the rod used. Other conditions which also influence the composition and quantity of the fumes and gases to
which workers may be exposed include: coatings on the metal being brazed (such as paint, plating, or galvanizing), the volume of
the work area, the quality and the amount of ventilation, position of the worker's head with respect to the fume plume, as well as the
presence of contaminants in the atmosphere (such as chlorinated hydrocarbon vapors from cleaning and degreasing activities).
When the material is consumed, fume and gas decomposition products generated are different in percent and form from the
ingredients listed in Section 3. Fume and decomposition products, not the ingredients in the rod, are important. Decomposition
products include those originating from the volatilization, reaction, or oxidation of materials in Section 3, plus those from the base
metal and coating, etc., as noted above. These components are virtually always present as complex oxides and not as metals
(Characterization of Arc Welding Fume: American Welding Society). Reasonably expected fume constituents of the fume could
include: complex oxides of copper and nickel. The table below lists reasonably expected fumes that may be generated:

Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone and nitrogen oxides may also be formed by
radiation from the arc. Monitor fume levels.
