Workers health protection in industrial companies considers the effects of all types of work on the health of the employees. In the area of soldering, consideration has to be given to the fact that the air while soldering and the hands holding the solder wire could be contaminated. Flux fumes can be damaging to health, and they should not be allowed to enter the breathing zone. Fume extraction units should be provided at each workplace, units, which remove the fumes and filter the air to remove particles and potentially damaging vapors. In rooms where soldering is taking place, there should be not consumption of food nor should there be any smoking. Contaminations found on hands could enter the body. For this reason, hygiene in the field of soldering is of imminent importance.
