We have a problem in my county with getting dispatch to follow the automatic aid plan.The county/city departmentS agree to this plan, along with the local 911 center. Time after time they wait for the responding officer to make the request.The reason being there fear of unnessary engine and tankers responding.I feel the fire departments themself have accept any libal not dispatch, that may arise from the plan in the event of a vehicle accident involding a fire servcie unit.ISO looks at automatic aid favorable.If the first unit on scene must ask it a delay and does not meet the ISO guideline.Please make any comments on how to work out this problem.
