Melting Lead Dangers

Melting lead is used in the production of stained glass windows and plumbing pipes in domestic and industrial buildings. It is also used by individuals in the production of fishing weights or ammunition for firearms. Melting lead should be used with extreme caution, as it can be toxic.

  1. Lead Dust

    • Molten lead is often used by hobbyists to paint figurines or to bind materials. This process creates fumes that can be dangerous if inhaled in sufficient concentrations. However, this process also leaves deposits of lead dust in the atmosphere of a house, which remain long after the soldering work has finished. The Environmental Defense Fund (EDF) suggests using a substitute alloy and refrain from melting lead in the home altogether. EDF also states that manufacturers of soldering products issue warnings on their products, outlining the risks of poisoning and advising ventilating a room before use.

    Fatality

    • Concentrated exposure to lead used in soldering can have fatal consequences. This occurs through oxide fumes which collect and poison the bloodstream. Symptoms of lead poisoning include abdominal aches; migraines; and anaemia, a condition characterized by a low production of red blood cells. Inhaling fumes caused by melting lead can lead to kidney failure, resulting in a patient reaching a coma state and eventually dying.

    Brain Damage

    • Melting lead can have detrimental effects on the brain, particularly among children. Children are more prone to damage as their brains are still in the developmental stage. The inhalation of molten lead flames can damage the growth of brain tissues and synapses in children. The National Institute of Environmental Health Science states that even small measures of lead poisoning results in decreased scores in competency tests among children. Melting lead can also lead to impaired cognitive function in adults due to the interruption of oxygen to the brain.

    Water Pollution

    • The Drinking Water Inspectorate states that melting lead can pose risks to the quality of drinking water. Molten lead is often used in the construction of pipes that supply drinking water to households. Some of the lead solder can enter the water as it runs through the pipes, posing health risks to families who drink it.
