Toxic pollutants in the workplaces of three major activities, viz.,explosive and solid propellant preparation facility, solid propellant shell assembling facility, andsolid propellant shell proof firing facility, were studied. The suspended particulate matter (SPM)concentration in grinding room (13.9 mg/m3) and sieving room (19.3 mg/m3) of solid propellantpreparation facility was observed to be two to threefold higher than the permissible limit. TheSPM in the dentex preparation section was found to be significantly high (10.8 mg/m3). Thepersonal exposure was fourfold higher (21 mg/m3) than the permissible limit. It was emerged thatconcentration of particulate is a major concern in all the processing sections. Since the chemicalnature of these particulates is expected to be more toxic in nature, it requires greater attention.At firing point, carbon monoxide appeared to be a major concern. ER -
