Japan has warned its citizens that, in the case of a North Korean nuclear attack, they may have as few as four minutes to rush to safety. The government's advice: those outside should proceed to a strong concrete building or underground in a calm, orderly fashion. Those already inside should stay low to the floor, take cover under tables and stay away from windows. Students are advised to hide under their desks. While "duck and cover" would do little for those engulfed by a nuclear fireball, it could protect the citizenry outside the explosion's radius from other dangers such as broken glass and other shrapnel, intense heat, thermal burns and eye damage. Japan knows this better than most. During the 1945 atomic bombing of Hiroshima and Nagasaki, Japanese citizens often rushed to the windows when they saw the bright flash of light, increasing the human toll of the attack. Sales of bomb shelters and air purifiers have skyrocketed in Japan in recent months.
