Potential health effects

Lithium Cobalt Oxide Blu-Black Powder (odorless) Cobalt and Cobalt compounds are considered to be possible human Carcinogen(s)By.IARC:May irritate eyes, skin, nose, throat,and respiratory system May cause allergic skin sensitization(rash). Carbon Black Powder (odorless) No cases of carbon being harmful to humans have been reported. WHO and ILO have never verified that carbon irritation of the skin and mucous membrane,etc In some individuals. Bond Odorless White Powder Inhalation and skin contact are expected to be the primary routes of occupational exposure to this material As a finished product,it is a synthetic,high molecular weight polymer,due to its chemical and physical properties,this material dos not CAUTION require special handing other than the good MELT I ndustrial hygiene and safety practical PROCEESING employed with any industrial material of RELEASES this type. Under normal processing VAPORS conditions,this material release fame or WHICH vapor components of these release may MAY vary with processing time and CAUSE temperatures. These process releases may EYE produce eye,skin and/or respiratory tract SKIN irritation and,with repeated or prolonged AND exposures,nausea,drowsiness,headache RESPIRATORY and weakness Although unlikely under TRACT normal handling conditions, if this IRRITATION material is heated in excess of 600F(315C) Hazardous,decomposition products will be Produced, hazardous decomposition products include hydrogen fluoride and oxides of carbon, the concentrations of which vary with temperature and heating regimens. Electrolyte Colorless Liquid May cause moderate to severe irritation, WARNING butting and dryness of the skin. May cause FLAMMABLE eye irritation or burning. Breathing REACTS WITH WSTER of the mists,vapors or fumes may irritate TO FROM the nose,throat and lungs or fumes may HYDROFLUORIC ACID irritate the nose throat and lungs Exposure MAY CAUSE BURNS TO of material with areas which contain water SKIN AND EYES may generate hydrofluoric acid which can EFFECTS MAY BE cause immediate burns on skin,severe eye DELEYED. MAY CAUSE bums burns to the mouth and BLINDNESS gastrointestinal tract if ingested,and PROBABLE laryngeal edema if inhaled.Direct REPRODUCTIVE exposure to areas of the body need to be treated immediately to prevent injury.
