Two reasons: First, these inspections are conducted by on-duty engine companies that must be ready to respond to an emergency call from the field. Second, an important part of the value of the public safety inspection is to familiarize your local firefighters with the buildings and business in Davenport. While they check for hazards and consult with business owners on how best to eliminate or minimize the likelihood of a fire, they also familiarize themselves with access points and the layout of the facility. Why do firefighters break out windows and cut holes in roof during a fire? Firefighters ventilate smoke, superheated, poisonous, or explosive gases for safety and visibility. This allows firefighters to get inside the building to find and extinguish the fire, thereby reducing property damage. This also reduces the chance of a possible dangerous explosion.
