Green Bay Fire Department (GBFD) firefighters are reluctant to request assistance by declaring a mayday situation even when conditions indicate the need for it. The purpose of this research is to identify why GBFD firefighters who are trained to call a mayday when faced with a situation that falls within certain defined parameters are not doing so. This Applied Research Project (ARP) used descriptive research methods to provide recommendations for improvement in mayday decision-making. The procedures used for this ARP were a literature review, distribution of two questionnaires and a request for information distributed to specific departments of similar size to Green Bay. Questionnaire responses were collected and analyzed electronically.Critical research questions are: 1) What nationally recognized situational parameters exist to determine when a firefighter should declare a Mayday? 2) What methods are other fire departments of comparable size in Wisconsin and bordering states using to encourage firefighters to declare a Mayday when conditions warrant? 3) What, if any, environmental cues do GBFD firefighters use to indicate when a mayday should be declared? 4) What, if any, training issues impact the decision to call mayday? and 5) What, if any, leadership issues impact the decision to call mayday? Relevant elements of current GBFD guidelines and policies were found to be similar to those of other organizations based on both internal and external response to questionnaires. GBFD firefighters were found to be subject to human error when making mayday decisions.This research also revealed that there does not appear to be nationally recognized mayday parameters to evaluate decisions against for validity. Seven recommendations have been provided to improve mayday decision making among GBFD firefighters.
