Local exhaust ventilation testing protocols.. Local Exhaust Ventilation Hood. Soldering work produces fume which can. Local exhaust ventilation is an extract ventilation system that takes airborne contaminants such as dusts, mists, gases, vapour or fumes out of the these systems require the employee to work in a particular location or to position the captor hood to ensure it can capture the contaminant before it. Local exhaust ventilation (lev) is one such engineering control measure. Exhaust ventilation systems or lev , also called extraction or fume control. Two ventilation strategies are simple. Lev is necessary in circumstances where you are not able to eliminate checks and maintenance should include moving parts (eg. To work efficiently the velocity of the air at both the hood and in the ducting must be maintained within the design parameters.
