IX. Spill Or Leak Procedure
Steps to be taken in case material is spilled or released:
Minor Spills: Contain the spilled material and then cover with a loose, absorbent material such as oildry, vermiculite,
sawdust, or fuller’s earth. Shovel waste material into proper waste containers. Do not make pressure tight. Transport to
a well-ventilated area and treat with a neutralizing solution consisting of a mixture of water and concentrated ammonium
Hydroxide or 5-10% sodium carbonate. Add about 10 parts of neutralizer per part of Isocyanate with mixing. Allow to
stand 48 hours letting evolved CO2 escape.
Major Spills: Call GRA Services International [phone]. If it is a transportation spill, transportation spill notify
Chem.Tel at [phone]. Evacuate and ventilate spill area. Dike spills to prevent entry into the environment. Wear
full protective equipment including respiratory protection during clean up.
If temporary control of Isocyanate vapor is required, a blanket of protein foam may be placed over the spill. Large quantities may
be pumped into closed but not sealed containers for disposal.
Clean Up: Decontaminate area using water/ammonia solution with 1-2% added detergent, letting it stand over affected
area for at least 10 minutes. Cover mops, brooms, etc used for this with plastic and dispose of properly (often by
incineration).
Waste Disposal Methods: Waste material may be incinerated at proper facilities or disposed of under Local, State, and Federal
regulations controlling environmental protection.
X. Special Precautions & Storage Data
Storage Temperature (Min/ Max): 65°F. (18°C.) to 75°F. (24°C.)
Average Shelf Life: 6 months from date of mfg.
Special Sensitivity (heat, light, moisture): This product is reactive with water. Containers should be tightly sealed to prevent
moisture contamination. A nitrogen blanket should be used for bulk storage at a temperature of 65°F to 75°F. Protect
from freezing.
Precautions in Handling and Storage: If contamination of the MDI is suspected, do not re-seal container because of
possible rupture due to pressure buildup. Always slowly vent container when opening to relieve any pressure buildup.
