The state and counties have canceled the monthly testing of the Statewide Outdoor Warning Siren System for 11:45 a.m. Thursday, the Hawaii Emergency Management Agency said Tuesday.

The state and counties agreed to cancel the test to avoid public confusion due to the current severe weather conditions as residents might confuse the testing for a real emergency.

If the siren tone is heard at times other than during a test, people are urged to tune to local radio, television station broadcast or cellular phones for emergency information and instructions provided by official government channels.

Hawaii’s attorney general is among 22 state attorneys general seeking legislation to end the use of what she called toxic “forever” chemicals, which includes the use of firefighting foam.

The chemicals are part of a group of super-resilient, man-made chemicals that contaminate drinking water and other media, a news release by the Department of the Attorney General says.

State Attorney General Clare Connors signed a joint letter urging Congress to pass laws that would help states address the public health threat of a family of chemicals known as per- and polyfluoroalkyl substances (PFAS).

PFAS contamination is often found in and around firefighting training centers, military bases, airports and industrial facilities, according to the news release.

“Congress must pass legislation to assist the states in combating this public health threat,” Connors said. “We need to limit our community’s exposure to these dangerous and toxic contaminants, and this effort seeks to provide Hawaii necessary resources.”
