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. |

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
Use product in accordance with
ANSI Standard Z49.1, Safety in welding and cutting available from AWS,

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. |

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. |
