Common questions
What problem was JESIP created to address?+
Inquiries into past multi-agency incidents found police, fire and ambulance services working in silos with inconsistent communication, so JESIP standardises joint working and shared situational awareness from the first response onward.
How does the shared decision log matter forensically?+
It creates a contemporaneous, time-stamped record of who decided what and when, which can later be checked against scene documentation and the forensic timeline if decisions affecting evidence are questioned.
