Designing and Installing a local Exhaust Ventilation to Exposure Control for Soldering Fumes in an Electronic Components Manufacture Industry in Kerman (2018)

There are different strategies to reduce employees’ exposure to chemical contaminants and their emission in workplaces out of which local exhaust ventilation is the most common engineering system that best suits our needs. The current study aims to design and install a local exhaust ventilation to control exposure to soldering fumes in an electronic components manufacture industry.

This is an Experimental study carried out in three steps in an assembly line for electronic components in Kerman in the summer of 2018: 1- collecting samples of contaminants produced during soldering 2- designing, manufacturing and installing a local exhaust ventilation 3- collecting samples of contaminants produced during soldering after designing an exhaust ventilation.

The results showed that employees had more exposure to tin and lead contaminants before designing and installing a local exhaust ventilation that was above the allowed rate. The results of designing an exhaust ventilation of 20.5 m3/min showed that tin and lead fumes rates could reach below the allowed rates in all workplaces.

The investigation and comparison of the allowed rates of exposure to soldering fumes and the density rates in workplaces before and after designing the local exhaust ventilation proved the high efficiency of controlling methods in the assembly line of electronic components
