(5 July 2018, 18:45)CharlesHarris Wrote: Police and Fire Dept whistle code in the US originated from that of the London Metropolitan Police and fire brigades dates from the 1880s:

One LONG blast - Traffic/hoist stop as directed by officer's hand or light signal

Two short blasts - Traffic/hoist may proceed (GO) as directed by traffic signal

Three LONG Blasts - EMERGENCY STOP! HOLD FAST!

Three LONG blasts of the whistle is recognised as an international distress call.

Two blasts of the whistle is the international recognition or call-back signal which means "Come here."

One blast is also recognized an inquiry signal which means "Where are you?"
or "SOUND AGAIN" as a call-back signal if you hear anything undetermined, which might be a code.

Short blast is ONE second.

LONG blast is THREE seconds.

Useful info Charles.

These codes could be used by a small or family group while evacuating or on patrol, or on a scavenging trip if no radios were available.
