âThe Center for Advanced Care is the linchpin in an overall plan to bring together our surgical, interventional and intensive care areas on a single, centrally located floor,â said Dr. Gary Seabrook, senior medical director of surgical services for Froedtert Hospital and chief of the division of vascular surgery at the Medical College of Wisconsin.
An assessment of the specific ways flammable and combustible liquids are stored, handled, used and disposed of is the best way to find out if existing ventilation controls (and other hazard control methods) are adequate. Some workplaces may need a complete system of hoods and ducts to provide acceptable ventilation.
I would question replacing ductwork unnecessarily - unless it is badly torn (flex duct) or rusted (metal duct), there is little benefit in replacing it. For sheet metal duct, a good brush and airjet cleaning followed by seam sealing should make it near as good at a small fraction of the cost. Flexible duct can also be airjet cleaned, though a camera run should be made afterward to identify any rips or joint separations from the cleaning, and fix them.
