Ingestion is hazardous due to the Carbon C 7440-44-0 0.03% max potential for internal tissue damage; in the event of ingestion, seek Chromium Cr 7440-47-3 18-20% max 16-18% medical attention immediately. Iron Fe 7439-89-5 Balance Manganese Mn 7439-96-5 2% max Operations such as welding, burning, and brazing may produce Molybdenum Mo 7439-98-7 0.25% max 2-3% hazardous metal fumes, and therefore proper safety precautions are Nickel Ni 7440-02-0 8-10.5% 10-14% Phosphorus P 7723-14-0 0.045% max required. Operations such as sawing, grinding, stamping, milling, Silicon Si 7440-23-3 1% max or machining may produce fi ne metal grit or dust which may pose Sulfur S 7704-34-9 0.03% max respiratory risks. Ortho Specialties mesh base material is composed of 316L stainless steel. Typical effects of acute overexposure to metallic dusts and fumes include irritation of the eyes, nose, and throat. In addition, exposure to Exposure limits for the above elements, listed below in milligrams per cubic high concentrations of iron oxide dusts, manganese, copper, zinc, or meter, are typically given for the respective elements in pure form, or in lead fumes can result in “metal fume fever” with symptoms including particular chemical compounds (cf. “form listed” in table below). Therefore metallic taste in the mouth, chills and fever, dryness and irritation in such exposure limits may not necessarily be applicable to stainless steel products in alloy form. (Note: “N/L” indicates that exposure limits for the the throat. Symptoms usually last 12 to 48 hours. (Metal fume fever element are not listed in the applicable regulations. is most serious in cases of lead, cadmium, and zinc fumes, none of which is present in stainless steel). Chronic overexposure to inhalation of high concentrations of metal Element OSHA Form ACGIH Form PEL Listed TLV Listed fumes or dust of the following elements may lead to the condition indicated: Carbon N/L Cr or Ni: dermatitis, infl ammation/ulceration of upper respiratory tract, Chromium 1.0 As Cr 0.5 As Salts possible cancer of nasal passages and lungs.
