From: Bronchial asthma and COPD due to irritants in the workplace - an evidence-based approach
Subcategories of irritant-induced OA | Exposure concentration | Duration of exposure |
|---|---|---|
Reactive airways dysfunction syndrome (RADS) | Extremely high, > OEL | ≤1 day |
Not so sudden onset of irritant-induced OA | Moderate, around OEL | >1 day <4 months |
Low dose irritant-induced OA | Low, below OEL | >4 months |
