Safer Storage
Provide extra safety for the storage of severe poisons.
Chemicals that have an LD50 of less than 300 mg/kg may
be described as fatal or toxic if swallowed. These should
be stored in a separate and secure storage cabinet to
protect against theft, vandalism, or fire.
The Flinn/SciMatCo® Poison Cabinet is compact and
will fit into an existing storage cabinet or shelf.
Severe poisons must be locked up. The Flinn/
SciMatCo Poison Cabinet is a “must” safety aid for any
high school chemical storage area.
