What Does Slightly Toxic Mean?
Slightly toxic materials are defined as those that may be harm- ful if swallowed. They have Oral-Rat LD50 values greater than 2000 mg/kg or Inhalation-Rat LC50 of 2200–22,000 ppm/hr. Practicing strict chemical hygiene is the most effective way to work safely with all chemicals. Rely on Flinn to help you under- stand chemical hazards and how they can affect you.
