2.1 Classification of the substance or mixture

Not classified under any GHS hazard class

2.2 Label elements

Not applicable (not classified) No know health hazards from copper tube in solid form. Under normal conditions of use, the solid article does not release more than very small quantities of hazardous substances and does not pose a physical hazard or health risk to employees. Metallic fumes may be released from heating copper tube above its melting point. May pose an inhalation hazard if

2.3 Other hazards

exposed above the recommended limits. May pose an inhalation hazard if exposed to metal dust from machining operations such as grinding or cutting such as filings or dust. Metallic copper may be moderately irritating to the gastrointestinal tract if ingested which is not a primary route of exposure. As sold, the solid article is not considered hazardous by Other hazard classifications: the OSHA Hazard Communication Standard (29 CFR 1910.1200) Section III – Hazard Identification EXPOSURE LIMITS HAZARDOUS CONSTITUENTS FOR CAS (mg/m3) WHICH PELs or TLVs EXIST ALLOYS PERCENT NUMBER OSHA1 ACGIH2 PEL TLV PEL/ TLV Element Established for Copper Dust 99.9% 7440-50-8 1 mg/m3 Fume 99.9% 7440-50-8 0.1 mg/m3 0.2 mg/m3 SUMMARY: These products may contain small amounts (<1%) of various chemicals in addition to those listed. These small quantities are frequently referred to as “trace” or “residual” elements that generally originate in the raw materials used. NOTE: No permissible exposure limits (PELs) or threshold limit values (TLVs) exist for these specific alloys. Values shown are applicable to component elements. Various combinations of the above components may appear in grades supplied. More specific information on a particular grade may be obtained by contacting Cambridge Lee Industries LLC. 1 OSHA Permissible Exposure Limits (PELs) are 8-hour Time-Weighted Average (TWA) concentrations unless otherwise noted. 2 Threshold Limit Values (TLV) established by the American Conference of Governmental Industrial Hygienists (ACGIH) are 8-hour TWA concentrations unless otherwise noted. A Short Term Exposure Limit (STEL) is a 15minute TWA exposure that should not be exceeded at any time during a workday, even if the 8-hour TWA is within the TLV-TWA.  Emergency Overview  Cambridge Lee Industries LLC considers this product in the solid form to be nonhazardous. However, operations such as abrading, burning, welding, sawing, brazing, grinding, cutting, polishing, and machining that results in the creation of dust or elevated temperatures may cause eye, skin, and respiratory tract irritation.
