It focuses on firefighters' demographic profile, occupational exposure, PPE compliance, prevalence of respiratory symptoms, and Pulmonary Function Test (PFT) outcomes. The study determines whether occupational smoke exposure and related factors are significantly associated with firefighters' lung function. A descriptive cross-sectional correlational research design was employed. 35 active firefighters were selected to answer survey component, while 11 qualified firefighters underwent Pulmonary Function Testing (PFT). Data were gathered using a validated researcher-made questionnaire reviewed by a Registered Respiratory Therapist, a Pulmonologist, and an Occupational Safety Officer. Actual PFT measurements included Forced Expiratory Volume in one second (FEVI), Forced Vital Capacity (FVC), and Peak Expiratory Flow Rate (PEFR). Data were analyzed using descriptive statistics, Chi-square tests, and regression analysis to determine relationships and differences among variables. Results show that 81.82% of participants have normal lung function, and no respiratory symptoms are reported. Chi-square analysis reveals significant associations between demographic factors (age, sex, and years in service) and exposure duration, PPE compliance, and PFT findings, while no significant association is found with frequency of fire/rescue responses. Regression analysis indicates positive but non-significant relationships among demographic factors, occupational exposure, PPE compliance, and lung function. Overall, firefighters maintain generally healthy lung function and high PPE compliance, and continuous respiratory health monitoring is recommended to support long-term occupational safety and well-being. author Hayagan, Jhowana Jena B. author Hayagan, Jerome P. lcc TH EAC Cavite-Thesis 0 100695 100695 0 0 lcc 0 0 CAVITE CAVITE EAC Cavite-Thesis 2026-11-10 0 T RT B38 2026 ML-TH2830 2026-11-10 11:25:28 2026-11-10 TH
