Hillsborough County Fire Rescue (HCFR) provides firefighting services to 589,000 citizens in a 931 square mile unincorporated area surrounding the Cities of Tampa, Temple Terrace, and Plant City. The promulgation of the Federal Occupational Safety and Health Administration (OSHA) Respiratory Standard, specifically the two-in and two-out rule, had been identified as a problem in that Hillsborough County Fire Rescue is unable to comply with the two-in and two-out portion when the rescue exception is not necessary. The purpose of this study was to develop potential compliance methods utilizing both existing resources and expansion of resources through funding of additional personnel and equipment.Descriptive, evaluative, and action research were utilized to answer the following questions: 1) What does HCFR currently do upon arrival at the scene of an interior firefighting situation when no rescue is presented? 2) How do other departments comply with the OSHA Respiratory Protection Standard? 3) How much of Hillsborough County is a non-compliance area for two-in and two-out? 4) What methods can HCFR employ to comply with the regulation? A reaffirmation of HCFR field operations provided the answer to research question one. To answer question number two, a survey was provided to one hundred fire rescue agencies to conduct information gathering of the present two-in and two-out compliance methods being utilized.Research question three was answered by conducting a review of geographic HCFR response capabilities utilizing a consistent measurement through the use of National Fire Protection Association criteria. Research question four was answered by the amalgamation of the survey responses, regulatory criteria, and HCFR existing and potentially fundable resources. The findings of the research indicated that over one third of Hillsborough County Fire Rescue's service delivery area is not able to comply with the intent of the two-in and two-out rule due to the existing deployment locations of suppression units and thier present staffing levels. The two-in and two-out survey displayed compliance methods such as adding apparatus, response procedure adjustments, and adding more personnel.Five methods of attaining compliance were assembled from the description and evaluation of the study date and are presented in the Recommendations section and are supported by the survey responses listed in Appendix B. To meet the intent of the regulation, the five methods of compliance in the answer to research question four are recommended. Training must also be conducted to ingrain the concepts of the regulation, as well as enforce sound safety procedures such as accountability, rapid intervention teams, and emergency procedures for lost or trapped members.
