Evacuate area surrounding the spill and prevent further spillage, leakage or entry into drains. Eye and skin
protection should be worn during spill cleanup and ventilation maintained. If the potential for airborne
concentrations of MDI above the PEL exists, then respiratory protection should be worn. Contain and cover spill
with loose absorbent (earth, sand, sawdust or other absorbent material), or absorbent pillows, pads or socks.
Collect absorbed material in open containers or plastic bags, and treat with deactivating solution (90% water, 8%
concentrated ammonia, 2% detergent). Allow to stand uncovered for 48-72 hours to permit carbon dioxide to
escape and solidification to occur. Wash spill area with deactivating solution and let stand for 30 minutes or
longer. Dispose of absorbed and neutralized material properly.
