Will the Hood Ventilation System pull in toxic smoke after an arc flash incident?
This is highly unlikely. Workers need the fresh air provided by an Oberon hood ventilation system to properly function during a work task execution. The risk of heat stress causing disorientation and dizziness is far more severe than the likelihood of the fan unit pulling in toxic fumes from an arc flash. Oberon has tested its hood ventilation system and made no observations of the fan causing any increased harm to the worker. When the fan unit is directly exposed to an arc flash incident the motor was rendered inoperable.
