This is a working document and is not to be construed as a complete list of safety considerations for any purpose.

Chemical

  • Lead fumes from Solder and circuit boards
  • Lead on hands from solder (and circuit boards
  • Lead and children

Flux Fume Information from Weller "Manufacturers of flux usually point out that inhaling flux fumes, created when flux is heated to soldering temperatures, will cause irritation to nose, throat and respiratory organs. Health authorities also state that extended or repeated exposure to rosin flux may cause hypersensitivity and lead to occupational asthma."

  • From Fermi Accelerator labs:"
    • Do not eat or drink in the work area.
    • Do not store food or drink in the work area.
    • Wash your hands thoroughly after soldering. Handling a cigarette or food with solder-contaminated fingers carries the possibility of ingesting lead-containing solder.
    • Drinks should not under any circumstances be consumed in the soldering work area.

It cannot be stressed enough to thoroughly wash your hands after soldering. Do not forget to clean your work area daily. Wiping your desk down with a wet rag or cleaning the desk surface with Windex and a Kimwipe will go a long way in minimizing ingestible lead contamination from your work surfaces." Just because a solder is free of lead it should not be thought of as non-toxic. The fluxes maybe, the fumes are the antimony and silver can be hazardous. Cadmium is hazardous. Overheating solder increases the vapor pressure of the metals present and increases the possibility of exposure.

Electrical components may contain other materials that are hazardous. Overheating them may release these components or cause highly hazardous compounds. Minimize heat if disassembling electronics and use good ventilation. Wash your hands after working and before eating or smoking. Artists use materials in novel ways and expose themselves to the possibility of novel hazards. When in the heat of things the temptation to take risks must be controlled.


Mechanical

High speed rotation can produce forces that exceed the strength of materials being spun and can lead to high speed projectiles. Make sure that you wear safety glasses and perhaps face shields when working with high speed motors, especially as the diameter of the spun object increases, , ask your instructor. Solenoids can operate at speeds high enough to cause harm. If you build or modify a solenoid care must be used, ask your instructor. Hair can get caught in small motors and pieces of scalp get torn off. The hazard exists even on some relatively benign seeming motors. Do not assume that just because it does not plug into the wall that it is not dangerous. Automated mechanical devices need special care. Nothing should be assumed to be "off" if it has a circuit board attached and power available.

Evolution of gas

  • Charging of batteries can lead to the evolution of explosive gases including hydrogen and oxygen
