STAY-SILV BRAZING FLUXES

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: These fluxes have the following characteristics: STAY-SILV WHITE BRAZING FLUX/DYNAFLOW FLUX - white, odorless paste; STAY-SILV BLACK BRAZING FLUX - smooth, black, odorless paste; STAY-SILV #99 POWDER BRAZING FLUX - fine, white powder with no odor; STAY-SILV WHITE POWDER BRAZING FLUX - fine, white, odorless powder. These fluxes and their decomposition products can moderately to severely irritate the skin, eyes, and any other contaminated tissue. These fluxes are neither flammable nor reactive under normal circumstances. If involved in a fire, the components of these products can decompose to release toxic gases. Emergency responders must wear the proper personal protective equipment suitable for the situation to which they are responding. (Continued) SYMPTOMS OF OVER-EXPOSURE BY ROUTE OF EXPOSURE: The most significant routes of over-exposure for these fluxes are by contact with HAZARDOUSMATERIAL INFORMATION SYSTEM skin, eye contact, or inhalation. The symptoms of overexposure to these fluxes , via route of entry, are as follows: HEALTH (BLUE) 2 INHALATION: If particulates of these fluxes are inhaled, they can moderately to severely irritate the nose, throat, and respiratory system. Symptoms of inhalation over-exposure may include coughing, sneezing, and difficulty breathing. FLAMMABILITY (RED) 0 CONTACT WITH SKIN or EYES: Depending on the duration and concentration of over-exposure, skin contact with these fluxes can moderately to severely irritate the skin. Repeated or prolonged skin over- exposure to these fluxes may result in dermatitis (red, dry, itchy skin). Depending on the duration and concentration of over-exposure, eye contact REACTIVITY (YELLOW) 0 with these fluxes can irritate the eyes. Eye over-exposure can cause tearing, redness, and tissue damage. SKIN ABSORPTION: Hydrogen fluoride, a possible decomposition product PROTECTIVE EQUIPMENT X of Stay-Silv White Brazing Flux/Dynaflow Flux And Stay-Silv Black Brazing Flux, is extremely corrosive and a poison by all routes of entry. Hydrogen EYES RESPIRATORY HANDS BODY fluoride can penetrate the skin and produce burns, which may not be immediately painful or visible; the burns impact the lower layers of skin and SEESECTION 8 bone tissue. Hydrogen fluoride exposures involving 20 percent of the body or more can be fatal through systemic fluoride poisoning. INGESTION: If swallowed call physician immediately! Do not induce For routine applications. vomiting unless directed by medical personnel. Rinse mouth with water if See Section 16 for Definition of Ratings person is conscious. Never give fluids or induce vomiting if person is unconscious, having convulsions, or not breathing. INJECTION: Though not anticipated to be a likely route of occupational exposure for these fluxes, injection (via punctures or lacerations by a contaminated object) may cause local reddening, tissue swelling, and discomfort in addition to the wound.

Potential health effects

OR RISKS FROM OVER-EXPOSURE An Explanation in Lay Terms. Symptoms associated with over-exposure to these fluxes are as follows: ACUTE: Symptoms of inhalation over-exposure may include coughing, sneezing, and difficulty breathing. Depending on the duration and concentration of over-exposure, skin contact with these fluxes can severely irritate the skin. Depending on the duration and concentration of over-exposure, eye contact with these fluxes can irritate the eyes. Severe ingestion over- exposure may be fatal. CHRONIC: Repeated or prolonged skin over-exposure to these fluxes may result in dermatitis (red, dry, itchy skin). Chronic over-exposure to hydrogen fluoride (a possible decomposition product of Stay-Silv White Brazing Flux/Dynaflow Flux And Stay-Silv Black Brazing Flux) can cause fluorosis (weakening and degeneration of bone structure and possible heart, nerve, and intestinal problems). Chronic ingestion over-exposure may to these fluoride-containing fluxes cause mottling of tooth enamel and hardening or abnormal density of the bones.
