Occupational Exposure Limit (dust/vapor) 2. Toxicity 3. Geno-toxicity 4. Default Control Band 3 (10 to 100 µg/m3) If toxicity data is not available . Containment strategy 2 Define Exposure Potential (EP) EP is based on: 1. Scale of use (Small, Medium, & Large) 2. Physical properties Liquids: Volatility (High,Medium & Low) Solids: Dustiness (High, Medium & Low) 3. Task duration ( Short & Long) 3 Derive containment strategy by linking SCB and EP
