The study used a light-scattering photometer, which counts the number of particles and converts them into mass, then expressed as µg/m³. The photometer recorded minute-by-minute levels of PM 2.5 over the duration of the study. The firecrackers tested were kept at distances normally kept by those who light them: For instance, the fuljhadi was kept at a distance of 1 ft, while the laad and anar were kept at a distance of 6 ft.
