Call for service
Calls for service generally refers to assignments that are typically distributed to public safety professionals that require their presence to resolve, correct or assist a particular situation. The calls are generally initiated by the public and relayed through the emergency telephone service (such as 9-1-1 in America, 999 in the UK, 000 in Australia and 112 across Europe, or similar) and divulged to the public safety personnel via a dispatcher by way of radio or some other telecommunication device. Generally, calls for service relate to the fields of the police, fire department and emergency medical services.
