To quantitatively evaluate the particle matter barrier performance of different firefighter protective clothing, a test platform was established using a high-precision environmental chamber and a particle generation device. Aerosol mixtures of sodium chloride, dioctyl sebacate and titanium dioxide particles were released to simulate a smoke-filled fire environment. The inward leakage rate was calculated based on the particle matter concentration distribution inside and outside the garments, allowing a quantitative assessment of the particle matter barrier performance of 4 types of protective clothing. The results demonstrate that firefighting garments and emergency-rescue suits provide inadequate protection for the upper and lower extremities. The light-duty chemical protective coverall exhibits the best overall performance, with an average total inward leakage rate of 4.69%, representing a 92.4% reduction compared to the control group. It demonstrates excellent protective capability. However, all four types of protective clothing are ineffective at blocking small particles with diameters of 0.3-1.0 μm.
