Reconstruction of major emergencies and crisis as well as observations of large-scale emergency exercises are common approaches for studying and understanding various actors work practice in emergency response. Studies of small-scale emergencies using an ethnographic approach are less common. This paper presents data from a single small-scale emergency as part of an extensive ethnographical field study. A detailed analysis of fire crew enroute sensemaking in a single small-scale emergency is outlined. The theory of sensemaking is applied as an analytical lens aiming to explain the communication between the command centre operator and the fire crew in terms of sensemaking. Further, implications for design of information technology use for fire crew enroute sensemaking will be presented as well as brief reflections of the consequences of such design.
