Most new houses in Henrico County were clad with vinyl siding. Vinyl siding presented challenges to firefighters because of its tendency to melt and burn. The problem was that no formal training was available to help firefighters (a) recognize the unique dangers presented by fires involving vinyl siding; or (b) amend their fire attack strategies accordingly. The research questions driving this effort were: (a) to what extent does vinyl siding contribute to fire growth; (b) what are the documented examples of rapid fire growth attributed to vinyl siding that resulted in firefighter maydays, loss of life, or significant property loss; and (c) what unique considerations should firefighters take when fighting fires in vinyl-clad houses. The research concluded that when vinyl is exposed to direct flames, or intense radiant heat, it does burn and contribute to fire growth.Case studies described how fires burned rapidly up vinyl-clad walls, then entered the structures through vulnerable openings such as vinyl attic soffits. The problems identified in these cases, along with the limited amount of existing training materials for vinyl fires, were used to develop strategy and tactics training for firefighters. This "action research" method resulted in a complete PowerPoint presentation. The research recommended the Henrico County Division of Fire provide the training to its members, share that training with other fire departments, and promote building code changes to reduce the vulnerability of vinyl-clad houses.
