What Does Moderately Toxic Mean?
Moderately toxic materials may be described as harmful if swallowed. They
have Oral-Rat LD50 values between 300–2000 mg/kg or Inhalation-Rat LC50
of 220–2200 ppm/hr. To avoid chemical contact, immediately clean up all
spills and never eat or drink in the lab. Rely on Flinn to help you understand
chemical hazards and how they can affect you.
