Guam Homeland Security issued a new fact sheet Friday, which the agency says will help residents prepare for an imminent missile threat.

The information was released following this week's threat by North Korea to launch a missile attack against Guam.

The advice includes tips such as: "Do not look at the flash or fireball – It can blind you" and "Take cover behind anything that might offer protection."

“Lie flat on the ground and cover your head. If the explosion is some distance away, it could take 30 seconds or more for the blast wave to hit,” the sheet states.

During a press conference at Adelup late Friday afternoon, Gov. Eddie Calvo told reporters that the threat level remains the same and that the island is "safe and sound."

"There are no changes," Calvo said. "Everyone should continue to live their lives."

While the governor said there's no imminent threat to the island, he said families should still be prepared any situation, including inclement weather, and establish a family emergency plan.

Homeland Security says residents should prepare an emergency supply kit and a family emergency plan. During an imminent missile threat, authorities recommend taking cover as quickly as possible under a concrete structure or below ground after an attack warning is issued.

People should also avoid going outside for at least 24 hours to avoid any possible radioactive material, unless otherwise told by authorities.

If possible, take a shower with lots of soap and water, shampoo but avoid using conditioner that will bind to any radioactive material in your hair, the fact sheet states.

After the explosion, people are encouraged to keep an eye and an ear out for official information so they know where to go, what to do and places to avoid.

Schools are safe buildings and teachers and staff should have detailed plans for emergencies. If children are in school, parents are advised to listen to the news, avoid calling the school and wait for instructions to pick up your child, the fact sheet states.

Guam Homeland Security spokeswoman Jenna Gaminde said the information from the fact sheet was gathered from the federal Department of Homeland Security website, www.ready.gov.

In the event of an imminent missile threat, Guam Homeland Security will use all forms of mass communication to alert the public, Gaminde said. This includes sounding all 15 All Hazards Alert Warning System sirens located in low-lying areas through the island. Emergency information will also be published on television and broadcast in emergency radio announcements.

GHS will also send alerts to local media, village mayors and publish information on its website if there is an imminent threat.

Social media users can follow Guam Homeland Security/Office of Civil Defense on Facebook and Twitter for timely notices.

“We recognize these are all separate forms of communication and rely on all during emergencies,” Gaminde said.

This fact sheet and others will also be available at local mayor’s offices, according to Guam Homeland Security.
