02 · GHS classification
Hazards and label elements
Harmonised classification under CLP Annex VI. This is the legally binding classification in the EU; other jurisdictions may differ.
| Code | Hazard statement |
|---|---|
| H350 | May cause cancer <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
| H340 | May cause genetic defects <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
| H372 | Causes damage to organs <or state all organs affected, if known> through prolonged or repeated exposure <state route of exposure if it is conclusively proven that no other routes of exposure cause the hazard>. |
Precautionary statements: P201, P260, P270, P280, P308, P313, P314

N-Methylolacrylamide properties
Every value is shown with the conditions it was measured under and the source it came from. Where sources disagree, all values are listed rather than one being picked — the difference is usually a different form of the substance, not an error.

04 · Handling and storage
Storing and handling N-Methylolacrylamide
Incompatible materials
Excessive heat, smoke, flames, and cracking noise were emitted from stored fibre drums of the monomer, some unopened. Polymerization may have been initiated by minor contaminants (perhaps as vapors), and/or by excessively warm storage conditions.

Reactivity
N-METHYLOLACRYLAMIDE may be sensitive to prolonged exposure to light. Polymerization and generation of heat and flames may occur on exposure to to heat or contaminants. Incompatible with strong oxidizers. (NTP, 1992)
