Suzy,

 

When designing a ventilation system to capture and transport toxic particulate such as lead particulate, a particulate filter (perhaps a HEPA) will generally be located as close as possible to the capture point to minimize contamination of the ducting and HVAC system.  Proper transport velocity Is also required to prevent settling out of the particulate.  One commonly used ventilation design guide is the ACGIH publication Industrial Ventilation: A Manual of Recommended Practice for Design (http://www.acgih.org/store/ProductDetail.cfm?id=2235). 

 

Regards,

Ben
