Fine dust accumulation in the human body
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 emission 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.
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.
The smaller the particles are, the deeper
they penetrate into the respiratory system.
The deeper the particles penetrate, the
higher the health risks.
The smallest particles travel via alveoli
into the bloodstream.
