The full protective clothing and self-contained breathing apparatus (SCBA) worn by Houston Fire Department firefighters for thermal and respiratory protection in hazardous environments reduces the firefighter's ability to communicate. This project addressed the problem that the Houston Fire Department needs a safe and effective means of communicating when firefighters use full protective clothing and SCBA. The purpose of this research project was to evaluate the equipment and techniques used in the Fireground Communication Pilot Program of the Houston Fire Department (HFD).Historical and evaluative research methods were used to determine (1) how have communication problems affected firefighters, (2) what is the HFD Fireground Communication Pilot Program, (3) does the equipment and methods used in the Fireground Communication Pilot Program provide effective communications, and (4) are there any elements of the Fireground Communication Pilot Program that can be altered or modified to improve the program. This research project was conducted with a literature review of published materials, interviews of HFD personnel, and a survey which provided information for an evaluation of the Fireground Communication Pilot Program. The evaluation used the Phase IV: Evaluation section of the Change Management Model taught in the Strategic Management of Change Course at the National Fire Academy.The study determined that communication problems have affected firefighters with ineffective equipment, reduced operational efficiency, and contributed to firefighter deaths and injuries. The HFD Fireground Communication Pilot Program was a field test of communication equipment with the objective of improving fireground communication with firefighters' wearing full protective clothing and SCBA. The evaluation of the pilot program found the equipment improved fireground communications, but did not meet the goals of the future state of fireground communications. The report recommends the continuance of the pilot program while improving the methods and equipment.
