Company ProfileEstablished in 1917 and based in Coventry, The Lawton Tube Company is the UK’s largest independent coppertube maker. The Company is a Private Limited Company without any group associations with the freedomnecessary to satisfy customer requirements and respond to product and process changes with the latest technicalrequirements.We offer a wide range of quality assured copper tubes, complying with the latest specifications, to both theconstruction and engineering markets. Lawton Tube is able to supply a range of standard products or special oneoff orders. Plant developments and installations have kept pace with market demands for a high integrity productand employ the latest manufacturing techniques. A fully integrated production system based on high speed blockdrawing and semi automated benches form the core of our primary processing.From initial extrusion to finished tube, Lawton Tube ensures that diameter, thickness, temper and length are allcontrolled within predetermined limits with the most up-to date manufacturing and inspection standards.Lawton Tube has been assessed and registered as a BSI Approved Company operating Quality Systems to meetthe requirements of BS EN ISO 9001-2008 and qualifies for the KITEMARK EN 1057 and EN 13348 (Medical).Lawton Tube was the first company in the United Kingdom to have the EN 13348 (Medical) KITEMARK. Fromreceipt of certified raw materials to final inspection and despatch the aim is to manufacture a tube fit for purpose.During 2001, Lawton Tube acquired Dorset Tube in Poole, which added to the breadth of Engineering tubesupplied by the Coventry unit and included the production of cupro-nickel brake pipe tube. Dorset Tube has beenassessed and registered as a BSI Approved Company and are operating Quality Systems to meet therequirements of BS EN ISO 9001-2008.Technical Guide 2009 Revision Page 3 of 29 The Lawton Tube Co.

COSHH – Hazard Data SheetCopper CU and Its SaltsGeneral Data – Grade 11 ChemicalCopper is reddish brown ductile malleable metal. It is highly conductive for heat and electricity. There are manyalloys of copper, brass and bronze being the most common.It forms two ranges of salts, cuprous and cuprice – the latter being more stable.Uses1. The manufacture of a wide range of alloys e.g.a. Brass which contains 37% zinc and other elements such as tin, manganese, nickel, iron andaluminum.b. Bronze which contains tin, lead, nickel phosphorous and silicon.c. High conductivity alloys containing silver, cadium and chromium.d. High strength alloys with beryllium, nickel, cobalt and silicon.e. For machinability with tellurium.f. When combined with 10%-30% nickel provides an alloy suitable for welding and capable of carryingcorrosive liquids.2. In the electricity industry for high conductivity.3. Building industry for piping water and gas.4. Copper Salts are colouring agents and fungicides.HazardCopper itself is virtually non-toxic in its industrial application. Some of the salts however, and particular coppersulphate are toxic if swallowed.Inhalation of the fume from welding or melting of brass leads to metal fumer fever but this effect is attributed tozinc oxide fume. Similarly the inhalation of powered bronze can cause metal fume fever.• Acute PoisoningIn industrial practice acute poisoning may arise in 2 ways:-1. By inhalation of fume from welding or brazing copper alloys. Metal fume fever develops some hours afterexposure.2. By swallowing copper sulphate solution which produces abdominal cramp, nausea, vomiting and diarrhea.• Chronic Poising – Unknown• Occupational Exposure Limits HSE EH40/89Long Term Exposure LimitShort Term Exposure LimitPPM Mg M3 PPM Mg M3Fume - 0.2 - -Dust - 1 - 1Technical Guide 2009 Revision Page 25 of 29 The Lawton Tube Co. Limited Registered Office: 165130 ENGLAND


PrecautionsAll melting, welding and brazing operations should be performed in controlled atmospheric conditions and shouldnot be undertaken in enclosed spaces without exhaust ventilation and fresh airline respirators.Personal Protective EquipmentA respirator to BS 2091 should be worn when other safety measures are not available.First Aid1. Inhalation of fume rarely causes immediate symptoms but if they occur remove from the fume. Oxygenand artificial respiration rarely called for.2. Ingestion of solutions of copper salts, particularly copper sulphate – dilute the poison by giving copiousquantities of water to drink.3. Remove the patient to hospital immediately together with a sample of fluid drunk and preservingspecimens of vomits.Technical Guide 2009 Revision Page 26 of 29 The Lawton Tube Co.
