Proven methods to either slow or stop fire spread in homes (e.g., fire sprinklers) should be considered. Here's another tactic the team at UL is promoting: keep your bedroom door closed while sleeping.
UL assembled a group of eight strangers and asked them about fire safety. Many of them didn't believe keeping a door open or closed had any impact on fire spread--that is, until they were taken to a fire test site and witnessed a burn firsthand. Watch their reactions in the following video created by UL to raise awareness about their #CloseBeforeYouDose campaign.
