Hawaii State Civil Defense will conduct the monthly test of its 170 sirens in its warning system at 11:45 a.m. today.
The test is a 45-second steady tone on all sirens.
State Civil Defense said when residents hear the steady tone in circumstances other than a test, they should turn to any radio or television station for essential emergency information and instructions.
During an actual emergency these broadcasts will be heard at frequent intervals and may become continuous if required.
In addition, residents in areas surrounding Campbell Industrial Park, Honokai Hale, Makakilo, Kapolei Regional Park, Kapolei Golf Course, and the Coast Guard Station at Kalaeloa may also hear a "whooping" tone following the siren test. This "whooping" tone is a test of the Hazardous Materials (HAZMAT) Incident outdoor siren warning group that will be activated in the event of a HAZMAT incident.
If the siren in a community does not sound or does not operate properly, residents are asked to call the Department of Emergency Management at 723-8960 to report it. The department’s email address is email@example.com.
Any acts of vandalism, damages, or missing sirens or components should be reported to the Department of Emergency Management at 723-8960. Include any images of damages or vandalism. Any suspicious activity should be reported immediately to the Honolulu Police Department by calling 911.
Residents also have the option of reporting malfunctioning or vandalized sirens online. Visit the City’s Siren Trouble Report page at http://www3.honolulu.gov/DEMSiren/ to file a report as well as upload pictures.
