15 mg/m3

IDLH (NIOSH)

300 mg/m3

Excerpts from Documentation for IDLHs

Basis for revised IDLH: No inhalation toxicity data are available on which to base an IDLH for ronnel. Therefore, the revised IDLH for ronnel is 300 mg/m3 based on acute oral toxicity in animals [AAPCO 1966; Klimmer 1971]. This may be a conservative value due to the lack of relevant acute toxicity data for workers.
