Solders are mixtures of different metals, characterized in that the melting point of the mixture is lower than the melting point of the corresponding metals (usually lead and tin). Generally, the use of solder will not produce toxic lead fumes, but only if a gas/air flame is used. Oxy-acetylene torches should not be used, as they heat up the solder much more and can cause lead fumes to be released.
Some fumes may also be released when any type of flame is used on surfaces covered with grease, etc. Inhalation of these vapors should be avoided at all costs.
When removing excess solder, care must be taken to avoid the formation of fine lead dust, which is very poisonous if inhaled. Respiratory protection may be required.
Solder splatter and chips should be collected and removed immediately to prevent general lead air pollution.
Strict personal hygiene practices are essential to avoid lead ingestion or inhalation of solder dust remaining on clothing.
