DMI Precaution and Packing

There are various kinds of materials suitable for use in handling DMI. The recommended materials are stainless steel, polyethylene and fluororesins at room temperature. For flange gaskets and gland packing, fluororesins (polytetrafluororesins and other polyfluoroethylenes) are suggested.

DMI is typically stored in iron, can or drum containers whose net weight is 18 kg and 200 kg respectively. DMI has a hygroscopic property and is oxidized more or less when it is exposed to air for a long period of time. Therefore, its storage containers should be kept sealed with inactive gas such as nitrogen.

When handling DMI at low temperature, please note that its melting point is 7.5° C. If the substance touches your skin, remove immediately by washing with water. Exposure to DMI can cause slight irritation as revealed in a test conducted on rabbit's skin. The toxicity of the chemical is as follows:

LD50 (Mouse Oral) >300-<2,000 mg/kg
LD50 (Rabbit Skin)            2,000 mg/kg
48 hours TLm 2,400 ppm


You should also refer to your local fire prevention regulations, when implementing fire-fighting procedures.
