Assessing Daily Exposure Risk of Pig Barn Workers to Airborne Contaminants
Airborne contaminants such as gases (ammonia and hydrogen sulphide) and dust, when exposed to pig barn workers increase the risk of respiratory symptoms and health problems. Occupational exposure risk was assessed when workers were doing their daily barn tasks in swine grow-finish rooms. The exposure of hydrogen sulphide, dust and ammonia were below the respective time-weighted average exposure limits, though symptoms at these limits may still be present. weighing and feeding pigs and draining manure pits have higher exposures and increase the risk of workers as they often exceed the 15 minute threshold.
