        "text": "Contractors use containment barriers, floor protection, and negative air filtration to safeguard surrounding rooms. Heavy plastic sheeting with zippered access points seals doorways, while temporary covers block HVAC supply and return vents to keep dust from circulating through ductwork. High-traffic walkways receive ram board or surface protection, and HEPA air scrubbers run continuously to capture fine particulate before it can settle outside the containment zone.",
