When not on scene using radios, fire departments and fire department members need to communicate in sub-groups, and as a whole. Fire station notice boards are no longer the solution.
Paper reports have their downsides also. At two in the morning, handwritting is increasingly illegible, firefighters make mistakes on who was in attendance or details of the incident, and those paper reports often go under reviewed.
Volunteer firefighters respond out of duty; to the community, to the department, and to their brothers/sisters in the service. Duty builds within the individual, and a culture of duty builds in the department, through firefighters engaging with the department; connecting with its mission, joining that mission.
