Firefighters with Station One fire department prepare

Firefighters with Station One fire department prepare to demonstrate a simulated-emergency evacuation as part of Fire Prevention week at Marine Corps Air Station Iwakuni, Japan, Oct. 14, 2017. Fire Prevention Week raises awareness in communities on how they can prevent, combat and aid where a fire can or is currently taking place in a real-world scenario. Fire Prevention Day was established Oct. 8, 1920, by President Woodrow Wilson to commemorate The Great Chicago Fire in 1871, which claimed 300 lives and left 100,000 homeless. It later became known as Fire Prevention Week in 1922 and has been proclaimed by the president every year since 1925, making it the longest running public health and safety observance on record.
