The heavy metal lead is easily malleable and has a relatively low melting point. It can be found in many different ways in the building industry. Among other things as lead sheet (roofing and edging), as lead pipes (domestic installations), as lead foil (around cables), as lead solder (glazing), as lead wool (caulking of joints), as colour pigment (lead carbonate = lead white/"Bleiweiß"; lead sulphate), as lead grenades (corrosion protection). It develops its toxicity mainly in the form of dust or in dissolved form.
