Soldering Safety and Procedures

Import Safety Notes:

When soldering, safety glasses, lab coats, and long pants must be worn as Personal Protective Equipment (PPE).  More details on soldering safety which MUST be followed can be found through EHRS (Link).

Soldering poses three main hazards:  

1. Burns and Fire The soldering iron, soldered joints, and soldering dross are sources of heat. The soldering iron tip can reach very high temperatures and will cause severe burns if touched. Soldered joints, molten solder, and soldering dross are initially hot and can cause burns until fully cooled.  The soldering iron can cause fires if it touches combustible or flammable materials.  

2. Flux/Rosin Fume Exposure Some solders contain rosin flux that generates smoke when soldering. The smoke contains chemicals and particles that can be irritating to the eyes and respiratory system. 

3. Lead and Other Metal Exposure Some solders contain lead (Pb) metal. Lead is a probable carcinogen and is a toxicant to multiple body systems. Chronic exposure to lead can lead to various health effects, including neurological effects such as decreased memory, learning and attention, weakness in extremities, anemia, kidney damage, cardiovascular effects, digestive issues, reproductive effects, and cancer.   Other metals used in solders (such as tin, silver, and indium) are less toxic than lead but still pose potential health hazards, particularly when ingested.
