AWS Specification: GROUP B: product For: CAST IRON ARC WELDING Electrodes . Trade Name: ENi C1; ENiFe C1. AWS Specification: SECTION 2 IDENTIFICATION OF HAZARDS. IMPORTANT The products described in Section I are not classified as hazardous according to applicable GHS hazard classification criteria as required and defined In OSHA Hazard Communication Standard (29 CFR Part ).

3 HAZARD CLASSIFICATION This product is not classified as hazardous according to applicable GHS hazard classification criteria. LABEL ELEMENTS: Hazard Symbol No symbol required Signal Word No signal word required Hazard Statement Not applicable Precautionary Statement Not Applicable HAZARDS NOT OTHERWISE CLASSIFIED. WARNING! Avoid breathing welding fumes and gases, they may be dangerous to your health. Always use adequate ventilation. Always use appropriate personal protective equipment. PRIMARY ROUTES OF ENTRY: Respiratory System, Eyes and/or Skin. ARC RAYS: The welding arc can injure eyes and burn skin. ELECTRIC SHOCK: Arc welding and associated processes can kill.

4 See Section 8. FUMES AND GASES: Can be dangerous to your health. Welding fumes and gases cannot be classified simply. The composition and quantity of both are dependent upon the metal being welded, the process, procedures and Electrodes used. Most fume ingredients are present as complex oxides and compounds and not as pure metals. When the electrode is consumed, the fume and gas decomposition products generated are different in percent and form from the ingredients listed in Section 3. Decomposition products of normal operation include those originating from the volatilization, reaction or oxidation of the materials shown in this section, plus those from the base metal and coating, etc.

5 , as noted above. Monitor for the materials identified in the list within this section. Fumes from the use of this product may contain complex oxides or compounds of the following elements and molecules: amorphous silica fume, calcium oxide, chromium, copper, fluorspar or fluorides, manganese, nickel, silica and zirconium. Other reasonably expected constituents of the fume would also include complex oxides of iron, titanium, silicon and molybdenum. Gaseous reaction products may include carbon monoxide and carbon dioxide. Ozone and nitrogen oxides may be formed by the radiation from the arc. 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 welded (such as paint, plating or galvanizing), the number of welders and the volume of the work area, the quality and amount of ventilation, the position of the welder'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).

6 One recommended way to determine the composition and quantity of fumes and gases to which workers are exposed is to take an air sample inside the welder's helmet if worn or in the worker's breathing zone. See ANSI/AWS , available from the "American Welding Society", Box 351040, Miami, FL 33135, 800-443-9353. SECTION 3 COMPOSITION/INFOMRATION ON INGREDIENTS. HAZARDOUS INGREDIENTS. IMPORTANT This section covers the hazardous materials from which this product is manufactured. This data has been classified according to the criteria of the GHS as required and defined in OSHA Hazard Communication Standard (29 CFR ). The fumes and gases produced during welding with normal use of this product is addressed in Section 8.
