<br /> Stability/Poly Lead is stable at room temperature irr closed containers under normal storage and handling conditions.It tarnishes or
<br /> •c„ exposure to air.Hazardous pal�mterizition cannot ocar.
<br /> Chemical Incompatlbllltks Mixtures of hydrogen peroxide+trioxane explode on contact with lead.Lead is incompatible with sodium azide,
<br /> zirconium,disodium acetylide,and oxidants.A violent reaction on ignition may occur with concentrated hydrogen peroxide,chlorine trifluioridr
<br /> sodium acetylide(with powdered lead) ammonium nitrate(below 200'C with powdered lead).Lead is attacked by pure water and weak organ
<br /> acids in the presence of oxygen Lead is resistant tg tap wale,hydrofluoric acid,brine,and solvents.
<br /> Conditions to Avofd:Rubber gloves containing lead may ignite in nitric acid
<br /> Hazardous Products of Decomposition:Thermal oxidative decomposition of lead can produce highly toxic fumes of lead.

<br /> Carcinogenicity:Although the NTP and OSHA do not list lead as a carcinogen,the IARC lists it as probably carcinogenic to humans,but havi
<br /> (usually)no human evidence.However,the literature reports instances of lead-induced neoplasms,both benign and malignant,of the kidney an
<br /> other organs in laboratory rodents.Excessive exposure to lead has resulted in neurologic disorders in infants.Experimental studies show lead h:
<br /> reproductive and teratogenic effects in laboratory animals.Human male and female reproductive effects are also documented.
<br /> r.. Summary or Risks:Lead is a potent,systemic poison that affect a variety of organ systems•including the nervous system,kidneys,reproducti,
<br /> system,blood formation,and gastrointestinal(GI)system.The most important way lead enters the body is through inhalation,but it can also be
<br /> ingested when lead dust or unwashed hands contaminate food,drink,or cigarettes.Much of ingested lead passes through fess without absorpti
<br /> into the body.Adults may absorb only 5 to 1595 of ingested lead;children may absorb a much larger fraction.Once in the body,leas enters the
<br /> bloodstream and circulates to various organs.Lead concentrates and remains in bone for many years.The amount of lead the body stores
<br /> v increases as exposure continues,with possibly cumulative effects.Depending on the dose entering the body,lead can be deadly within several
<br /> days or affect health after many years.Very high doses can cause brain damage(encephalopathy).
