3. Hazard Identification
Emergency Overview
Products which this sheet refer to have solid metallic form and therefore the nickel cannot develop as possibly as hazardous material. No toxic
effects caused by the material in the solid state or during the normal orthodontic practices have been produced. A prolong and frequent contact may
cause skin irritation and other allergic reactions in subject sensitive to nickel.

metal are usually reported to be
relatively non-toxic, although there are
reports of a type of pulmonary disease.
Some insoluble chromium compounds
are suspect carcinogens.
Nickel: Respiratory irritation and
pneumonias; several nickel compounds
including nickel oxide, are suspected
lung and nasal carcinogens.
Molybdenum: irritation of the nose and
throat, weight loss and digestive
disturbances in animals. No industrial
poisoning has been reported.
Cobalt: May cause asthma, pneumonias
and sensitization of the respiratory
system.

with the following chemical components.
Medical Conditions Aggravated by Exposure
Notes: Some constituents pose more potential hazards than others, depending upon their inherent toxicity and concentration. Of special concern are
chromium, nickel and may be manganese. Aggravation of pre-existing respiratory or allergic conditions may occur in some workers.

Hazardous Products Produced During Decomposition
Fumes and gases from welding cannot be classified simply. The composition and quantity of both depend on the metal being processed, procedures
and the electrodes used. The constituents of the fume are generally different from the ingredients listed in section I and may include oxides of the
metals, chromates, fluorides and metallic complex. Gases may include carbon monoxide, oxides of nitrogen and ozone. The following exposure
limits apply to those fumes and gases which may be found in the welding environment.
