The potential health hazards involved with this product arise from its use. On heating metal and metal oxide fumes may be evolved but are unlikely to exceed the stated OEL’s under normal conditions. Severe overheating could lead to the emission of fumes in harmful concentrations but as the soldering temperatures are around 300 oC this event is unlikely. It is recommented to prevent overheating of the soft solders and to have good extraction in connection with the workplace. N.B. : Some alloys in section 2. Contain Lead & Cadmium. Cadmium containing soft solders: COSHH Regulations list the exposure limits for cadmium oxide as a MAXIMUM EXPOSURE LIMIT (MEL) which must never be exceeded. Short exposure to high levels of cadmium oxide can lead to pulmonary oedema and may be fatal. Prolonged or repeated over exposure to cadmium oxide fume is reported as causing renal damage. There is a symptomless latent period and any person thought to have been over exposed to cadmium oxide fume should be kept under observation for 48 hours. Cadmium oxide fume is reported as being carcinogenic and may cause cancer by inhalation. Boiling temperature of the containing metals are: Silver ........... 2210 °C Tin ........... 2270 °C Lead ........... 1740 °C Cu ........... 2595 °C Cd ........... 765 °C Zn ........... 907 °C As the melting range for the mentioned soft solders are between 183 - 398 oC is it unlikely that the exposure limits will be exceeded. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
