molecular sieve desiccant, composed mainly of aluminosilicates, is inert and non-toxic under normal conditions. Its solid granules or pellets, used in packing for drying applications, pose minimal risk when handled properly, as they do not release harmful substances or react with most materials.
However, risks arise with fine dust from damaged or crushed molecular sieve. Inhaling this dust can irritate the respiratory tract, causing coughing or discomfort, especially in individuals with pre-existing conditions. Prolonged exposure may lead to cumulative irritation, emphasizing the need for masks during maintenance or when handling broken packing.
Accidental ingestion is rare but potentially problematic, as the desiccant could absorb moisture in the mouth or throat, causing mild irritation. Additionally, some specialized molecular sieve desiccants treated with chemicals for enhanced adsorption might pose greater risks, though these are tightly regulated for industrial use.
Overall, molecular sieve desiccant is safe with basic precautions: avoiding dust inhalation, wearing protective gear, and storing it away from food or children. These measures ensure its effective use in drying without significant health risks.
