Cyclonite Chemical Sampling Information
Cyclonite

General Description
    Synonyms: Cyclotrimethylenetrinitramine; Hexahydro-1,3,5-trinitro-1,3,5-triazine; Hexahydro-1,3,5-trinitro-s-triazine; RDX; Trimethylenetrinitramine; 1,3,5-Trinitro-1,3,5-triazacyclohexane

    OSHA IMIS Code Number: 2224
    IMIS Name History: RDX (Cyclotrimethylene Trinitramine) prior to 9/1/89

    Chemical Abstracts Service (CAS) Registry Number: 121-82-4

    NIOSH, Registry of Toxic Effects (RTECS) Identification Number: XY9450000

    NIOSH Pocket Guide to Chemical Hazards, Cyclonite: chemical description, physical properties, potentially hazardous incompatibilities, and more
Exposure Limits
    OSHA Permissible Exposure Limit (PEL) for Construction Industry: 29 CFR 1926.55 Appendix A -- 1.5 mg/m3 TWA; Skin

    OSHA Permissible Exposure Limit (PEL) for Maritime: 29 CFR 1915.1000 Table Z-Shipyards -- 1.5 mg/m3 TWA; Skin

    American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Value (TLV): 0.5 mg/m3 TWA; Skin; Appendix A4 - Not Classifiable as a Human Carcinogen

    National Institute for Occupational Safety and Health (NIOSH) Recommended Exposure Limit (REL): 1.5 mg/m3 TWA, 3 mg/m3 STEL; Skin
Health Factors
    Environmental Protection Agency (EPA) carcinogenic classification: Group C, possible human carcinogen.

    Potential symptoms: Irritation of eyes, skin; headache, irritability, lassitude (weakness, exhaustion), tremor, nausea, vomiting, dizziness, confusion, insomnia, convulsions, unconsciousness (postictal coma), postictal amnesia; tachycardia, ventricular premature beats; petechial rash; methemoglobinemia; kidney damage (hypokalemia, metabolic acidosis, proteinuria, glucosuria, myoglobinuria)

    Health Effects: Irritation-Eyes, Nose, Throat, Skin (intensity unknown); Acute CNS Toxicity (HE7)

    Affected organs: Eyes, skin, CNS

    Notes:
    1. OSHA does not have a PEL for cyclonite, a component of C-4 and some other explosive materials.
    2. 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.
    3. EPA’s oral Reference Dose (RfD), the daily oral exposure likely to be without appreciable health risk during a lifetime, is 0.003 mg/kg/day.
