Michael Flatley had to leave is Irish castle because of PVC residue after house fire.
“The Flatley’s left their home after experts conducting routine maintenance of the house detected unsafe levels of chloride residue from PVC on the walls and furniture of the property.
Mr Flatley's counsel Ronnie Hudson, instructed by solicitor Max Mooney, said that the residue came from the combustion of PVC during a fire at the property in 2016, and is carcinogenic.”

When PVC burns, its chemical breakdown releases hydrogen chloride (HCl) gas. This gas is highly reactive. As it travels through a house during a fire, it binds with moisture in the air and on surfaces to form hydrochloric acid, which deposits onto walls, furniture, and structures as a corrosive and toxic chloride residue. If the smoke soot isn't properly remediated, carcinogenic byproducts like dioxins trapped in that residue can linger for years
Examples of common household items made from PVC that could have burned:
Electrical wire insulation (the plastic wrapping on cables)
Plumbing pipes (drain, waste, and vent pipes)
Vinyl window frames and windowsills
Vinyl flooring (tiles, sheets, or luxury vinyl planks)
Vinyl wallpaper and wall coverings
Vinyl siding (exterior wall cladding)
Plastic window blinds and curtain tracks
Vinyl upholstery on furniture (faux leather chairs or couches)
Shower curtains and liners
