3. HAZARD IDENTIFICATION (Continued)

CONTACT WITH SKIN or EYES: Contact of the rod form of these

products with the skin is not anticipated to be irritating. Contact with

the rod form of these products can be physically damaging to the

eye (i.e., foreign object). Fumes generated during brazing

operations may be irritating to the skin and eyes. Symptoms of skin

over-exposure may include irritation and redness; prolonged or

repeated skin over-exposures may lead to dermatitis. Contact with

the molten core rods will burn contaminated skin or eyes. Eye

contact with dusts or particulates generated by the flux coating on

the flux coated products will cause irritation, pain, tearing, and

reddening. Brief contact may cause eye damage and prolonged

contact may cause permanent damage. Depending on the duration

of over-exposure, skin contact with dusts or particulates generated

by the flux coating on the flux coated products may cause irritation

and burns. Chronic over-exposure to dusts or particulates

generated by the flux coating on the flux coated products may

cause borism (dry skin, eruptions, and gastrointestinal

disturbances) or pustular dermatitis (visible collections of pus).

SKIN ABSORPTION: In some situations, one of the decomposition

products

of the flux coating may be hydrogen fluoride. Hydrogen

fluoride can penetrate the skin and produce burns that may not be

immediately painful or visible; the burns impact the lower layers of

skin and bone tissue. Hydrogen fluoride exposures involving 20

percent of the body or more can be fatal through systemic fluoride

poisoning.

INGESTION: Ingestion of rods is not a likely route of exposure.

INJECTION: Though not a likely route of occupational exposure for

any of these products, injection (via punctures or lacerations in the

skin) may cause local reddening, tissue swelling, and discomfort in

addition to the wound.

HEALTH EFFECTS OR RISKS FROM EXPOSURE: An Explanation in Lay

Terms. Symptoms associated with over-

exposure to these products and the fumes generated during brazing operations are as follows:

ACUTE: The chief acute health hazard associated with these products would be the potential for irritation of contaminated

skin and eyes when exposed to fumes during brazing operations. Inhalation of large amounts of particulates generated by

these products during metal processing operations may be physically irritating and cause deposits of dust in nasal passages.

Inhalation of dusts and fumes of Copper, Manganese, and Zinc (constituents of these products) can cause metal fume fever.

Symptoms can include a metallic or sweet taste in the mouth, sweating, shivering, headache, throat irritation, fever, chills,

thirstiness, muscle aches, nausea, vomiting, weakness, fatigue, and shortness of breath. Contact with the molten material

will burn contaminated skin or eyes. If particulates or fumes, generated during brazing operations, are ingested (i.e., through

poor hygiene practices), nausea, vomiting, diarrhea, stomach ache, degeneration of blood and liver cells, gastro-intestinal

bleeding, decreased urine output, listlessness, rapid heartbeat, convulsions, and coma may occur. Severe ingestion over-

exposure may be fatal. Depending on the duration of over-exposure, dusts or particulates generated by the flux coating on

the flux coated products may be irritating or damaging to the entire respiratory tract, eyes, and skin. In some situations, one

of the flux coating’s decomposition products may be hydrogen fluoride. Hydrogen fluoride can penetrate the skin and

produce burns that may not be immediately painful or visible; the burns impact the lower layers of skin and bone tissue. If

dusts or particulates generated by the flux coating on the flux coated products are swallowed, they may burn the mouth,

throat, esophagus, and other tissues of the digestive system.
