Guam has posted emergency guidelines to help residents prepare for any potential nuclear attack following the rise in tension between North Korea and the US.
This week Pyongyang's state-run news agency said its army would complete plans in mid-August to fire four intermediate-range missiles over Japan to land near Guam, a US territory and military base, amid increasingly heated rhetoric over the North Korea's nuclear weapons program.
Guam's governor Eddie Calvo said there was no heightened threat but the government had issued a preparedness fact sheet, which covered what to do before, during and after a nuclear attack.
"Do not look at the flash or fireball - It can blind you," it said. "Take cover behind anything that might offer protection."
If caught outside, it said to "remove your clothing to keep radioactive material from spreading."
It suggests having an emergency plan and supply kit and a list of potential concrete structures near home, work and school to serve as fallout shelters.
The fact sheet advises people to not scrub or scratch the skin, use soap, shampoo and water but avoid hair conditioner because it binds radioactive material.
It also advises parents to stay where they are and wait for instructions, even if they are separated from their children.
Military solutions are now fully in place,locked and loaded,should North Korea act unwisely. Hopefully Kim Jong Un will find another path!— Donald J. Trump (@realDonaldTrump) August 11, 2017
Earlier in the week US President Donald Trump spoke meeting North Korean threats with "fire and fury".
His comments took an more ominious turn when he tweeted that military solutions were now "locked and loaded".
Governor Calvo said while he agreed with sending a clear message to North Korean leader Kim Jong Un, he didn't "want the temperature to get any higher".
