CASE STUDY 1: In 2004, two 35-yr old Vietnamese Immigrants, Toan Bui and Ha Vu, were refinishing hardwood floors in a tree family house in Somerville, a city on Boston's northern periphery. This was not at all an unusual scene. The older cities of New England feature tens of thousands of nineteenth and early twentieth-century houses with fine old wood floors, which periodically need to be refinished. Toan Bui and Ha Vu were typical workers in a typical trade - until in 2004, when they died on the job in a fiery and entirely preventable disaster in which two co-workers were also badly burned. They had finished sanding the old floors and were coating them with a lacquer sealer that is typically 80 percent flammable solvent, with the remainder a mixture of resins that serve to coat and protect the wood. The entire house caught fire in a matter of seconds after the lacquer sealer was ignited by a pilot light in a gas stove. ESTIONS: 1. What are the ways to extinguish fire caused by flammable substances? 2. What are the fire equipment and devices that must be used to prevent fires especially when handling and working with flammable substance? What are the OSHA regulations with regards to fire safety? 3
