Can these structures be used for vapor containment (negative pressure)?
Yes. Mahaffey structures serve as environmental enclosures allowing work to proceed in all weather conditions. For negative pressure applications Mahaffey can provide framed ventilation ports to which other suppliers can connect their ductwork. Inner liners are also available for quick post-project disposal without surprise charges for equipment decontamination. Review a case study of how the U.S. Army Corp of Engineers used a temporary environmental enclosure to excavate a site contaminated with WWII mustard gas.
