An Exploration of Pulmonary Fitness of Construction Workers in Delhi NCR in Light of the Building and Other Construction Workers Act, 1996

ABSTRACT

Workers in the construction sector are exposed to high concentrations of particulate matter at their workplace. This increases their susceptibility to various respiratory diseases, particularly chronic obstructive pulmonary disease (COPD) and acute respiratory distress syndrome (ARDS). The study reports comparative pulmonary fitness and hematological parameters of the migrant workers in the construction sector versus other sectors in Delhi. Parameters such as forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1 ), the ratio of FEV1 to FVC, and peak expiratory flow were measured in both groups using a spirometer. We observed significant differences (P < 0.05) in FEV1 and FVC between both groups. The study thus confirms that workers exposed to poor air quality at the construction site are susceptible to respiratory diseases, particularly ARDS. All of this reflects the poor enforcement of the adequate safety measures well enlisted in social legislations such as the Building and Other Construction Workers Act.
