Galvanized sheet surfaces may be chemically treated, generally at the customer's specification, with trace amounts of chromate solution(approximately 1 to 2 mg/ft per side or < of total product weight) to prevent humid storage stain, and/or phosphate solutions (<300 mg/ft or < ) to enhance paint adherence and formability. Surface may also be treated with small amounts (< ) of corrosion-inhibitingoil.

4 All commercial steel products may contain small amounts of various elements in addition to those specified. These small quantities (less ) may exist as intentional additions, or as "trace" or "residual" elements that generally originate in the raw materials used. These elementsmay include: aluminum, antimony, arsenic, boron, cadmium, calcium, chromium, cobalt, columbium, copper, lead, molybdenum, nickel, silicon,tin, titanium, vanadium, and zirconiumGalvanized (Hot dipped ) Sheet - Carbon Steel Rev. 05/02 OSHA Permissible Exposure Limits (PELs) are 8-hour TWA (time-weighted average) concentrations unless otherwise noted.

5 A ("C") design-Exposure Limit (STEL) is defined as a 15-minute exposure, which should not be exceeded at any time during a workday. Threshold Limit Values (TLV) established by the American Conference of Governmental Industrial Hygienists (ACGIH) are 8-hour TWA concentrations unless otherwise noted.

The concentration of inhalable particulate for the application of this TLV is to be determined from the fraction passing a size-selector with the characteristics defined in the ACGIH TLVs and BEIs Appendix D, paragraph A. PNOS (Particulates Not Otherwise Specified). Particulates identified under the PNOS heading are "nuisance dusts" containing no asbestos and <1% crystalline silica. A TWA-TLV of 10 mg/m for inhalable particulate and 3 mg/m for respirable particulate has been recommended.

8 Respirable fraction. The concentration of respirable dust for the application of this limit is to be determined from the fraction passing a size-selector with the characteristics defined in the ACGIH TLVs and BEIs Appendix D, paragraph C. The 8-hour PEL is 50 ug/m . If an employee is exposed to lead for more than 8-hours in any work day, the PEL, as a TWA for that day, shall be reduced according to the following formula: Maximum permissible limit (in ug/m ) = 400 divided by hours worked in that day. The Action Level is 30 ug/m averaged over an 8-hour formed solid metal product poses little or no immediate health or fire hazard. When product is subjected to welding, burning, melting, sawing, brazing, grinding, or other similar processes, potentially hazardous airborne particulate and fumes may be generated.

9 Avoid inhalation of metal dusts and fumes. Operations having the potential to generate airborneparticulates should be performed in well ventilated areas and, if appropriate, respiratory protection and other personal protective equipment should be used. Iron or steel foreign bodies imbedded in the cornea of the eye may produce rust stains unless removed fairly promptly. Primary Entry Routes: Inhalation and skin, if coated. Steel products in the natural state do not present an inhalation, ingestion or contact hazard. However, operations such as burning, welding, sawing, brazing, machining and grinding may result in the following effects if exposures exceed recommended limits as listed in Section Organs: Respiratory Effects: Inhalation: Excessive exposure to high concentrations of dust may cause irritation to the eyes, skin and mucousmembranes of the upper respiratory tract.

10 Excessive inhalation of fumes of freshly formed metal oxide particles sized below microns and usually between - microns from many metals can produce an acute reaction known as "metal fume fever". Symptoms consist of chills and fever (very similar to and easily confused with flu symptoms), metallic taste in the mouth, dryness and irritation of the throat followed by weakness and muscle pain. The symptoms come on in a few hours after excessive exposures and usually last from 12 to 48 hours. Long-term effects from metal fume fever have not been noted. Freshly formed oxide fumes of manganese, copper and zinc have been associated with causing metal fume fever.
