Natural lead is a mixture of four stable isotopes: Pb-204 (1.4%), Pb-206 (25.2%), Pb-207 (21.7%) and Pb-208 (51.7%). Lead isotopes are the end-products of each of the three series of naturally occurring radioactive elements: Pb-206 for the uranium series, Pb-207 for the actinium series and Pb-208 for the thorium series. Forty-three other isotopes of lead, all of which are radioactive, are ...
Hazard pictograms alert us to the presence of a hazardous chemical. The pictograms help us to know that the chemicals we are using might cause harm to people or the environment. The CLP hazard pictograms are very similar to those used in the old labelling system and appear in the shape of a ...
A chemical hazard symbol is a pictogram applied to containers of dangerous chemical compounds to indicate the specific hazard, and thus the required precautions. There are several systems of labels, depending on the purpose, such as on the container for end use, or on a vehicle during transportation.
Lead is the fifth element of the fourteenth column in the periodic table. It is classified as a post-transition metal, a heavy metal, and a poor metal.

The long history of Lead is reflected in the many different words for this metal. See the list of names to the left and in the overview of Lead in over 100 languages . We can identify many different roots, even the three main European branches of the Indo-European language group have five different roots (some related) for their name of this common metal: plumbum, the Germanic languages use ...

Although lead makes up only about 0.0013% of the earth's crust, it is not considered to be a rare element since it is easily mined and refined. Most lead is obtained by roasting galena in hot air, although nearly one third of the lead used in the United States is obtained through recycling efforts.
Health Hazard. In the list of hazard symbols and meanings, this particular symbol shows that exposure to a particular substance may cause very serious and prolonged health effects. Never swallow such substance and ensure that it does not touch your skin surface.
The Hazard Communication Standard (29CFR 1910.1200) requires all manufacturers or distributors of any products containing chemicals to evaluate the chemical hazards of the product. The evaluation is performed by classifying each chemical based on published toxicological or other data to determine its physical and health hazards.
OSHA 1910.1200 requires communication of chemical hazards, and lists labels as one of many appropriate methods. However, it doesn't specify a particular labeling system. The NFPA 704 and other chemical hazard identification systems are intended for different audiences and also differ in their use of the white field. The resources below may help ...
A thorough Hazard Identification and Risk Analysis, or risk, system is the core element in the RBPS pillar of understanding hazards and risk. This chapter describes the meaning of risk for RBPS purposes, the attributes of a risk system, and the steps an organization might take to implement a robust program for identifying hazards and analyzing ...
Lead is a naturally occurring element found in small amounts in the earth's crust. While it has some beneficial uses, it can be toxic to humans and animals causing of health effects. Lead can be found in all parts of our environment – the air, the soil, the water, and even inside our homes ...
Hazard symbol are recognizable symbols designed to warn about hazardous materials, locations, or objects, including electric currents, poisons, and other things. The use of hazard symbols is often regulated by law and directed by standards organizations.
Hazard Symbols. For recognition purposes, the hazard symbols in the catalog are from Title 49 of the Code of Federal Regulations (CFR), part 172 (DOT), yet the criteria used for assigning hazard symbols is primarily from the American National Standards Institute (ANSI) standard Z129.1 for Hazardous Industrial Chemicals Precautionary Labeling.
The Chemical Identifier fields include common identification numbers, the NFPA diamond, U.S. Department of Transportation hazard labels, and a general description of the chemical.The information in CAMEO Chemicals comes from a variety of data sources.
Lead Lead may give off toxic vapors when heated. Lead compounds in the form of finely divided powders may be carried by air currents. Lead and lead compounds, like and heavy metal, should not be disposed of by sewer. People using lead and lead compounds are …
Lead nitrate is a white crystalline solid. The material is soluble in water. It is noncombustible but it will accelerate the burning of combustible materials. If large quantities of the material are involved in the fire an explosion may result. Prolonged exposure of the material to fire or heat may result in an explosion.

Aug 22, 2016· Hazard symbols have come a long way from the rudimentary drawings used to designate poison in the early 1800s. As a result of updated OSHA chemical labeling requirements, 2016 marks the first full year of adoption of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) in the U.S.
Alloys include pewter and solder. Tetraethyl lead (PbEt 4) is still used in some grades of petrol (gasoline) but is being phased out on environmental grounds. Lead is a major constituent of the lead-acid battery used extensively in car batteries. It is used as a coloring element in ceramic glazes, as projectiles, in some candles to threat the wick.
Lead is a relatively abundant element because it the endpoint of the decay schemes of many radioactive elements with higher atomic numbers. Because it's fairly easy to extract (for a metal), lead has been used since prehistoric time. Lead was readily available to common people in the Roman Empire, finding use in dishes, plumbing, coins, and ...
