- OSHA does not have a PEL for cyclonite, a component of C-4 and some other explosive materials.
- Intoxications with cyclonite among military personnel by intentional (but not suicidal) oral abuse (chewing C-4) or by accidental inhalation while using C-4 as a cooking fuel have been reported.
- EPAs oral Reference Dose (RfD), the daily oral exposure likely to be without appreciable health risk during a lifetime, is 0.003 mg/kg/day.
