98 90 minutes soldering with leadfree solder wire before after Fine dust accumulation in the human body The smaller the particles are, the deeper they penetrate into the respiratory system The deeper the particles penetrate, the higher are the health risks The smallest particles travels via alveoli into the bloodstream It is important to use the correct safety equipment to remove these hazardous substances. Fine particles are more dangerous to inhale than big particles as they get caught more easily and block the alveoli in the lungs. To protect the operator it is important to use an extraction system that is able to separate these particles and gases and then re-circulates the cleaned air back into the work place. This saves energy and reduces energy costs. Many work environments today, including soldering, adhesives, welding and laser applications, create particles and gases that can be harmful to the work place and the environment. Most people thought that the move to leadfree soldering would be more nature friendly. In reality leadfree soldering smoke emissions contain more breathable fine dust particles. More smaller particles are produced due to the higher working temperatures required and because more flux is used in the soldering process. In many countries legal regulations governing clean air in the work place require that hazardous substances are removed from the air in order to avoid harmful effects on people and machines.
