| H361f | Suspected of damaging fertility. |
| H331 | Toxic if inhaled. |
| H311 | Toxic in contact with skin. |
| H301 | Toxic if swallowed. |
| H373 | May cause 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>. |
| H411 | Toxic to aquatic life with long lasting effects. |

04 · Fire and explosion
Fire and explosion behaviour of 2,5-Dinitrotoluene
These are descriptions rather than measured values, so they are kept out of the table above and quoted here with the source that reported them.
Fire and explosion
Potentially explosive if heated to decomposition temperatures in confined spaces or detonated. ... Organic contaminants lower decomposition temperatures & incr risk of explosion. /Dinitrotoluenes/
