  • Toxicity data
    ORL-RAT LD50 2.4 mg kg-1
    ORL-MUS LD50 8.1 mg kg-1
    SKN-RAT LD50 1.7 mg kg-1
  • Highly toxic if swallowed, inhaled or absorbed through the skin. Exposure to even small amounts may be fatal. Readily absorbed through the skin.
  • Vapor (Inhalation/Ocular)
    ECt50 (Mild) = 0.1 mg-min/m3
    ECt50 (Severe) 2 = 10 mg-min/m3
    LCt50 = 15 mg-min/m3
    Vapor (Percutaneous)
    ECt50 (Threshold) 5 = 10 mg-min/m3
    ECt50 (Severe) 2 = 25 mg-min/m3
    Liquid (Percutaneous)
    ED50 = 2 mg/70 kg man
    LD50 = 5 mg/70 kg man
    LCt50 = 150 mg-min/m3
We don't have broken glassware. You want to see the risk assessments...

Been there, done that, chickened out coz I like living . Can send you some students to test some of those chemicals on if you ever doubt the validity of the MSDS sheets .
