Product Aluminum 5ectiari 6:.Health Hazard Data MOTE-. STEEL PRODUCTS IN THE NATURAL STATE DO NOT PRESENT AN INHALATION,INGESTION OR CONTACT HAZARD. HOWEVER.OPERATIONS SUCH AS BURNING,WELDING.SAWING,BRAZING AND GRINDING MAY RELEASE FUMES AND/OR DUSTS WHICH MAY PRESENT HEALTH HAZARDS IF TLVS ARE EXCEEDED MAJOR EXPOSURE HAZARD &nhalation Pt>Skin Contact Skin Absorption Eye Contact Ingestion !iiHeCjs of Oveiexposure Aluminum dust should be treated as a nuisance dust and high exposure may produce irritation of eyes and respiratory system. The potential for overexposure to copper fumes may exist when welding,flame cutting,etc.on alloys containing high amounts of copper>2.5%. These alloys include 2XXX,7XXX and 4145 wrought alloys. Overexposure to copper fumes can result in respira- tory irritation,nausea and metal fume fever. Nickel and chromium are contained in certain alloys at levels of 0.1%or more. Chromium and nickel and their compounds are listed in the 3rd Annual Report on Carcinogens,as prepared by the National Toxicology Program(NTP). Their presence in Aluminum alloys,however,should not present a carcinogenic or health concern due to either their low concentrations or the chemical form in which they are present. Inhalation or ingestion of lead particles may result in lead-induced systemic toxicity. Symptoms of lead poisoning include abdominal cramps,anemia,muscle weakness and headache. Prolonged exposure can cause behavioral changes,kidney damage,CNS damage and reproductive effects. Plasma arc cutting or welding aluminum can generate ozone_ Overexposures to ozone can result in mucous membrane irritation, as well as pulmonary changes including irritation,congestion and edema. Suspected Cancer Agent? NO: This product's ingredients are not found in the fists below, —.){,._YES: —Federal OSHA XNTP — IARC Emergency and First Aid Procedures If exposed to excessive levels of metal fumes,remove to fresh air,seek medical aid immediately. Eyes- Flush with water for at least 15 minutes. Spill or Leak Procedures NA Waste Disposal Melhods According to local,state and federal regulations Section 8 5�ecaf ProteCttoR-. r �, '�+ h9- i rte.4r Respiratory NIOSHIMSHA Approved dust and fume, respirator should be used to avoid excessive inhalation of particulates when exposure exceeds TLV's. Ventilation Local exhaust ventilation should be utilized when welding,burning,sawing,brazing,grinding or machining when exposure exceeds TLV's. Eye Projection and Protective clothing Safety glasses or goggles should be utilized as required by exposure. Other protective equipment should be utilized as required by the welding standards. Sect+qrr=9 Special PreCilitions ": _,. 1. Halogen acids and sodium hydroxide in contact with aluminum may generate mixtures of hydrogen. 2. Finely divided aluminum will form explosive mixtures in air. It will also form explosive mixtures in air in the presence of bromates,iodates or ammonium nitrate. 3. When remelting aluminum scrap,entrapped moisture or the presence of strong oxidizers such as ammonium nitrate could cause an explosion. This applies to the collection of moisture in sow cavities as well. Moisture must be driven oft prior to remelting. 4. Do not touch cast aturninum metal or heated aluminum product without knowing metal temperature. Aluminum experiences no color change during heating. If metal is hot and touched,burns can result. 5. Hard alloy ingots in the 2000 and 7000 series must be stress relieved to prevent explosion when sawed. 6. The welding of aluminum alloys may generate carbon monoxide,carbon dioxide,ozone,nitrogen oxides,infra-red radiation and ultra-violet radiation.
