Behind greens aerification, there is probably nothing that the golf course superintendent does that upsets the golfing public more than the early-morning call to the pro shop with the dreaded words  FROST DELAY. Most golfers don't have a very good understanding of why frozen or frosted turf can't be played on.
The Incident Commander (IC) or the Unified Command (UC) is responsible for all aspects of the response, including developing incident objectives and managing all incident operations. The IC is faced with many responsibilities when he/she arrives on scene.
Based on the ICS system and the scope of the incident, EMS providers may be assigned or responsible for any number of roles. These roles may range from incident commander on a strictly medical situation to that of an operational or support unit member in a large multiple agency response to a major incident.
