| Fire hazards | The flash point of this compound is not available, however it is probably non-flammable. (NTP, 1992) |
| Hazards summary | May cause irritation[MSDSonline] |
| Reactive group | Amides and Imides |
| Reactivity Profile | BIUREA is chemically classified as an amide. Amides/imides react with azo and diazo compounds to generate toxic gases. Flammable gases are formed by the reaction of organic amides/imides with strong reducing agents. Amides are very weak bases (weaker than water). Imides are less basic yet and in fact react with strong bases to form salts. That is, they can react as acids. Mixing amides with dehydrating agents such as P2O5 or SOCl2 generates the corresponding nitrile. The combustion of these compounds generates mixed oxides of nitrogen (NOx). |
| Air and Water Reactions | Insoluble in water. |
| Hazard Classes and Categories | Skin Irrit. 2 (11.9%) |
| Fire fighting | Fires associated with this compound should be controlled with a dry chemical, carbon dioxide or Halon extinguisher. (NTP, 1992) |
| First aid | EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop. |
