SECTION III 鈥? PHYSICAL DATA (Non-Applicable)
SECTION IV 鈥? FIRE AND EXPLOSION DATA
(NON-FLAMMABLE) Welding arc and sparks can ignite combustible. Refer to ANSI Z49.1 for precaution to be taken.
SECTION V 鈥? REACTIVITY DATA
HAZARDOUS DECOMPOSITION PRODUCTS: The composition and quantity of welding fumes and gases can be influenced by such factors as
the process being utilized, the material being welded, electrode type used, condition of base material being welding on, type of exhaust and the
presence of contaminates in the atmosphere.
The percent and form of the fume and gas decomposition generated while being consumed are different than the hazardous ingredients
listed in Section II. New compounds of fume and gas not in the consumables may form. Decomposition products are a combination of the
ingredients listed in Section II and the variable factors stated above.
Ozone and nitrogen oxides may be formed by the radiation from the arc. Gaseous reaction products may include carbon monoxide and
carbon dioxide.
SECTION VI 鈥? HEALTH AND HAZARD DATA
THRESHOLD LIMIT VALUE: The ACGIH recommended limit for welding fume is 5 mg/m3.
EFFECTS OF OVEREXPOSURE: short-term Overexposure (acute) to welding fumes my result in such discomfort as: dryness or irritation of the
nose, throat, or eyes, dizziness or nausea. Long-term Overexposure (chronic) may lead to siderosis and affect pulmonary function. Arc rays can
injure eyes and burn skin. Electric shock can kill. Noise can damage hearing.
EMERGENCY & FIRST AID PROCEDURES: Call for medical aid. Employ first aid techniques by the American Red Cross.

CARCINOGENIC: Chromium and Nickel and their compounds are listed by the IARC and the NTP as posing a carcinogenic risk to humans.
SECTION VII
Read and understand the manufacturer鈥檚 instructions and the precautionary label on the product. Refer to ANSI Z49.1 published by the
American Welding Society.
VENTILATION: Use enough ventilation, local exhaust at the arc or both to keep fumes and gases below TLV鈥檚 in the worker鈥檚 breathing zone and
the general area. Train the welder to keep his head out of the fumes.
RESPIRATORY PROTECTION: Use respirable fume respirator or air supplied respirator when welding in confined spaces or where local exhaust or
ventilation does not keep exposure below TLV.
PROTECTIVE CLOTHING: Wear head, hand and body protection that help prevent injury from radiation, sparks, and electrical sparks.
PROCEDURE FOR CLEAN UP OF SPILLS AND LEAKS: (Not applicable)
WASTE DISPOSAL METHOD: Prevent waste from contaminating surrounding environment. Discard any product, residue, disposable container or
liner in an environmentally acceptable manner, in full compliance with Federal, State and Local regulations.
