Siren test on Friday


The Cheyenne/Laramie County Emergency Management Agency will be testing the outdoor warning siren system promptly at 10 a.m. Friday, Dec. 2 for Pine Bluffs and at noon in Cheyenne and surrounding towns. The warning system will sound a steady signal for a period of one to three minutes.

The siren system is the most effective method to warn the population at large in the shortest amount of time. They are called outdoor warning systems because their primary purpose is to alert people who are outside to severe weather, chemical or other emergencies.

Individuals may hear the sirens in their house, although that's not the primary function of the sirens. However, those in their basements probably won't be able to hear the sirens as each siren is rated at 127 decibels. At 127 decibels, the sirens are just a bit louder than a jet engine on take off.

Not only does distance play a part to why individuals won't be able to hear the sirens in their basement, other factors such as wind, terrain, other background noise and building walls (insulation), effect how sound travels and reduces the exterior noise heard inside of a building.

During an actual emergency, when residents hear the sirens, they should take cover immediately and tune into a local radio or television station to receive additional emergency information. Residents should not call 911 or local emergency officials for information as this ties up telephone liens needed for emergency operations.

The sirens are an all-hazards emergency warning system and are intended to warn residents of any life threatening situations in the area.
