Exposure Standards and Regulations
Action levels for poisonous or deleterious substances are established by the FDA to control levels of contaminants in human food and animal feed. Action levels and tolerances are established based on the unavoidability of the poisonous or deleterious substances and do not represent permissible levels of contaminantion where it is avoidable. The blending of a food or feed containing a substance in excess of an action level or tolerance with another food or feed is not permitted, and the final product resulting from blending is unlawful, regardless of the level of the contaminant. Action levels and tolerances represent limits at or above which FDA will take legal action to remove products from the market. Where no established action level or tolerance exists, FDA may take legal action against the product at the minimal detectable level of the contaminant. /Lead/ Commodity Action Level (ug/ml leaching solution) Ceramicware: flatware (average of 6 inits) 3.0 Ceramicware: small hollowware (other than cups and mugs)(any 1 of 6 units) 2.0 Ceramicware: large hollowware (other than pitchers)(any 1 of 6 units) 1.0 Ceramicware: cups and mugs (any 1 of 6 units) 0.5 Ceramicware: pitchers (any of 6 units) 0.5 Silver-plated holloware: product intended for use by adults (average of 6 units) 7 Silver-plated hollowware: product intended for use by infants and children (any 1 of 6 units) 0.5
Reactivities and Incompatibilities
Intimate mixtures of chlorinated rubber and ... /lead oxide/, with or without hydrocarbon or chlorinated solvents, react violently or explosively when heated at about 216 deg C. If in milling such mixtures local overheating occurs, a risk of a violent reaction exists. Such risks can be minimized by controlling milling temperatures, by cooling, or by using a mixture of maximum possible fluidity. /Chlorinated rubber: metal oxides/
/Chlorine/ mixtures with ethylene explode ... over lead oxide at 100 deg C. /Chlorine: hydrocarbons/
Pure /dichloromethylsilane/ is not ignited by impact, but it is in presence of ... lead(II) ... oxide ... even under an inert gas. /Dichloromethylsilane: oxidants/
/A mixture of lead oxide and glycerol (formerly used as a jointing compound)/ ignites in contact with gaseous fluorine ... /Fluorine: miscellaneous materials/
Dispersions of lead oxide in fluoroelastomers underwent severe exothermic decomposition when heated above the normal mixing temperature of below 200 deg C, forming elemental lead.
During maintenance work on casings of fans used to extract perchloric acid fumes, seven violent explosions occurred when flanges sealed with lead oxide-glycerol cement were disturbed. The explosions, attributed to formation of explosive compounds by interaction of the cement with perchloric acid, may have involved perchlorate esters and/or lead salts. Use of an alternative inorganic silicate-hexafluorosilicate cement is recommended. /Perchloric acid: glycerol, lead oxide/
Contact /of hydrogen trisulfide/ with ... lead(II) oxide ... causes violent decomposition and ignition. /Hydrogen trisulfide: metal oxides/
Interaction /of lead oxide/ at 200 deg C with rubidium acetylide is explosive, and with lithium acetylide, incandescent.
... Finely divided sodium ignites on admixture with /lead/ oxide, and a mixture of the latter with zirconium explodes on heating. Titanium is also oxidized violently on warming.
A mixture /of lead oxide/ with boron incandesces on heating, and with silicon the reaction is vigorous. If aluminum is present the mixture explodes on heating (but the same is true if silicon is absent).
... Additions /of/ 2-3 drops of about 90% /peroxyformic/ acid ... /to/ lead (II) oxide ... cause an immediate violent explosion. /Peroxyformic acid: metals or metal oxides/
A strong explosion occurred when aluminum was heated with ... lead oxide, the crucible was broken to pieces and the doors of the furnace were blown off. /Aluminum:copper oxide/
Over a period of time, perchloric acid fumes from a laboratory hood condensed on the cover plate of the exhaust fan, which was sealed with a cement of glycerine and litharge (lead monoxide). When a workman tapped the plate with a chisel, a violent explosion caused 2 injuries and 1 fatality.
Other Preventative Measures
SRP: Contaminated protective clothing should be segregated in such a manner so that there is no direct personal contact by personnel who handle, dispose, or clean the clothing. Quality assurance to ascertain the completeness of the cleaning procedures should be implemented before the decontaminated protective clothing is returned for reuse by the workers. All contaminated clothing should not be taken home at end of shift, but should remain at employee's place of work for cleaning.
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
Disposal Methods
Generators of waste (equal to or greater than 100 kg/mo) containing this contaminant, EPA hazardous waste number D008, must conform with USEPA regulations in storage, transportation, treatment and disposal of waste. /Lead/
