A pest control company fumigated one of two buildings in an apartment complex with a toxic gas in order to eliminate unwanted insects. Even though the company exercised reasonable care, the gas escaped into the other building, which adjoined the fumigated building, where the gas caused serious illness to a tenant in that building. The tenant had received a written advance notice about the fumigation that advised the tenant of the need to vacate his apartment during the hours the fumigation was conducted. The tenant chose instead to remain there in order to watch a favorite television program. The applicable jurisdiction treats fumigation as an ultrahazardous activity. The injured tenant filed an action against the pest control company. Who will prevail?
