NIC-L-WELD 99 and WELCO 94

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: These products consist of coated rods, odorless electrodes. There are no immediate health hazards associated with these products. Inhalation or contact with dusts or fumes of nickel, a component of these products, and can cause sensitization. These products are not reactive. If involved in a fire, these products may generate irritating iron fumes, a variety of nickel, iron and silicon compounds, and metal oxides. Nickel, the main component of these products is possibly carcinogenic to humans. Emergency responders must wear personal protective equipment suitable for the situation to which they are responding. SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: During welding operations, the most significant route of over-exposure is via inhalation of fumes. INHALATION: Inhalation is not anticipated to be a significant route of over-exposure to the coated electrodes. Repeated over-exposures, via inhalation, to the dusts or fumes generated by these products during welding operations may have adverse effects on the lungs with possible pulmonary edema and emphysema (life-threatening lung injuries). (continued on following page) (Continued) INHALATION (continued): Hypersensitivity to Nickel, the main component of this product, is common, and can cause pulmonary HAZARDOUS MATERIAL IDENTIFICATION SYSTEM asthma and pneumonitis (an inflammatory disease of the lungs). Refer to Section 10 (Stability and Reactivity) for information on the specific composition of welding fumes and gases. HEALTH (BLUE) 2 CONTACT WITH SKIN or EYES: Contact of these products with the skin is not anticipated to be irritating. Contact with these products can be physically damaging to the eye (i.e., foreign object). Fumes generated during welding operations can be result in sensitization resulting in conjunctivitis (inflammation of the irritating to the skin and eyes. Prolonged exposure of the eyes may FLAMMABILITY (RED) 0 mucous membranes of the eyes). Skin contact with dusts or fumes of these products can result in allergic contact dermatitis. Contact with the hot electrodes will burn contaminated skin or eyes. REACTIVITY SKIN ABSORPTION: Skin absorption is not known to be a (YELLOW) 0 significant route of over-exposure for any component of these products. INGESTION: Ingestion is not anticipated to be a route of occupational exposure for these products. PROTECTIVE EQUIPMENT X INJECTION: Though not a likely route of occupational exposure for these products, injection (via punctures or lacerations in the skin) may cause local reddening, tissue swelling, and discomfort.

Potential health effects

OR RISKS FROM EXPOSURE An Explanation in Lay Terms. Symptoms associated with over- exposure to these products and the fumes generated during See welding operations are as follows: ACUTE: The chief acute health hazard associated with these For routine industrial applications for the rods. products would be the potential for irritation of contaminated skin and eyes when exposed to fumes during welding operations. Inhalation of large amounts of particulates generated by these See Section 16 for Definition of Ratings products during metal processing operations can result in pneumoconiosis (a disease of the lungs). Contact with the hot electrode will burn contaminated skin or eyes. CHRONIC: Chronic skin over-exposure to the fumes generated during welding operations may produce dermatitis (red, inflamed skin). Nickel, the main component of these products, is potentially carcinogenic to humans. Hypersensitivity to Nickel is common and can cause allergic contact dermatitis, pulmonary asthma, conjunctivitis and inflammatory reactions. Repeated over-exposures to the fumes generated by these products via inhalation can have adverse effects on the lungs (e.g., pulmonary edema and emphysema). Refer to Section 11 (Toxicological Information) for further information. TARGET ORGANS For fumes ACUTE Skin, eyes, respiratory system.
