Hazardous Decomposition Products |
 The composition and
quality of welding fumes and gases are dependent upon the metal being
welded. The process procedure and electrodes used. Other conditions
which also influence the composition and quantity of fumes and gases to
which workers may be exposed include:coatings on metal being welded
(such as paint, plating,or galvanizing), the number of welders and the
volume of the worker area, the quality and amount of ventilation, the
position of the welder’s head with respect to the fume plume, as the
presence of contaminants in the atmosphere (such as chlorinated
hydrocarbon vapors from cleaning and degreasing activities.)
When the electrode is consumed, the fume and gas
decomposition products generated are different in percent and from the
ingredients listed in Section II. Decomposition products of normal
operation include those originating from the volatilization, reaction.
or oxidation of the materials shown in Section II, plus those from the
base metal and coating, etc, as noted above .
Reasonably expected fume constituents of this product
would include: Primarily iron oxide and manganese oxides,secondarily
complex oxides of chromium, potassium, silicon and sodium
Maximum fume exposure guideline for this
product(based on manganese content) is 0.5 milligrams per cubic meter.
SECTION VI – Health
Hazard Data
Route(s) of Entry:
Inhalation , Skin, Ingestion
Health Hazards
Electric ARC-welding may create: Fumes and gases can
be dangerous. Arc rays can injure eyes and burn skin. Electric shock can
kill.
Carcinogenicity
The state of California requires the following information:
Warning: This product contains chemicals known to the state of
California to cause cancer.
Signs and Symptoms of Exposure
See below.
Medical Conditions from Exposure
Short term to Welding fume-dizziness nausea, dryness and irritation of
nose, eyes and throat, chest tightness, fever, allergic reaction, long
term-siderosis, believed to affect pulmonary function. Nickel and
Chromium compounds are required by Osha to be considered carcinogenic.
Emergency and First Aid Procedures
Remove to fresh air, obtain medical attention, Employ first aid
techniques recommended by AM.Red Cross.

N/A
Waste and Disposal Method
Prevent waste from contaminating surrounding environment. Discard any
product residue, disposable container or liner in environmentally
acceptable manner, in full compliance with federal, state, and local
regulations.
Precautions to be Taken in Handling and Storing
None
Other Precautions

SECTION VIII –
Control Measures
Respiratory Measures
Use restorable fume respiratory or air supplied
respirator when in confined space or local exhaust does not keep
exposure below recommended exposure limit.
Ventilation
Use enough local ventilation, and local exhaust at AEC to keep fumes and
gases from workers breathing zone and general area. Train worker to keep
head out of fumes.
Local Exhaust ---- Special ----
Mechanical (General) ---- Other ----
Protective Gloves
See other protective equipment
Eye Protection
Wear helmet, face shield with filter lens, protective
screens, flash goggles to shield others, start with shade too dark then
go to lighter shade which gives sufficient view of weld zone.
Other protective Equipment
Hand, head, body protection to prevent injury form radiation, sparks and
electrical shock.
Work/Hygienic Practices
Do not touch live electrical parts and insulate from work and ground.
For maximum safety, be certified for, and wear a respirator at all times
when welding or brazing.
