Step 3 : Determine Degree of Hazard (Inhalation, Acute Toxicity)

Choose LC50 Information

Select... LC50≤ 0.5 mg/l (vapours) LC50≤ 100 ppmV (gases) LC50≤ 0.05 mg/l (dusts/mists) 0.5 < LC50 ≤ 2.0 mg/l (vapours) 100 < LC50 ≤ 500 ppmV (gases) 0.05 < LC50 ≤ 0.5mg/l (dusts/mists) 2 < LC50 ≤ 10 mg/l (vapours) 500 < LC50 ≤ 2500 ppmV (gases) 0.5 < LC50 ≤ 1 mg/l (dusts/mists) 10 < LC50 ≤ 20 mg/l (vapours) 2500 < LC50 ≤ 20000 ppmV (gases) 1 < LC50 ≤ 5 mg/l (dusts/mists) LC50 > 20 mg/l (vapours) LC50 > 20000 ppmV (gases) LC50 > 5 mg/l (dusts/mists)
