|SECTION V – Reactivity Data
||Conditions to Avoid
||None unless otherwise specified
|Incompatibility(Metals to Avoid) None |
|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
Electric ARC-welding may create: Fumes and gases can be dangerous. Arc rays can injure eyes and burn skin. Electric shock can kill.
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
|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.

|Spill and Leak Procedure 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
Use product in accordance with ANSI Standard Z49.1, Safety in welding and cutting available from AWS, 550NW. Lejnue Rd., POB 351040, Miami, F133135 Phone 305-443-9353.
|SECTION VIII – Control Measures
Use restorable fume respiratory or air supplied respirator when in confined space or local exhaust does not keep exposure below recommended exposure limit.
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 ----
|Mechanical (General) ----
|| Other ----
See other protective equipment
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.
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.
