Exposure limit(s)
NIOSH REL: TWA 1.5 mg/m3 ST 3 mg/m3 [skin]
Exposure effects
Generalized seizures have been reported in workers exposed to cyclonite, as has confusion, loss of consciousness, exhaustion, vertigo and postictal coma. Irritability, insomnia, restlessness and anxiety were prodromal symptoms seen in workers who later became toxic. Ingestion has resulted in generalized seizures and status epilepticus.
   Ingestion
Nausea and vomiting may occur in workers exposed to cyclonite by any route. See inhalation.
   Inhalation
Symptoms: irritation eyes, skin; headache, irritability, fatigue, weakness, tremor, nausea, dizziness, vomiting, insomnia, convulsions Target Organs: Eyes, skin, central nervous system.
   Skin
Irritant and allergic contact dermatitis have been reported in workers who manufacture cyclonite. See inhalation.
   Eyes
See inhalation.

First aid
 
   Ingestion
Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
