Although Crock-Pot objected to one of its products being used as the cause of a fatal, if fictional, home fire, the National Fire Protection Association (NFPA) says the episode of the NBC TV show “This is Us” depicting the blaze provides valuable lessons. In the highly-rated drama, a defective slow cooker sparks a fire in the kitchen of a home that quickly spreads to curtains and then to the rest of the house. The family members are trapped in second floor bedrooms.
