How Should the SAA
Look?
Required by Regulation
Containers
Compatible with contents (e.g., no metal containers for
corrosives or certain plastics for organic solvents)
Good condition / no leaks / secure closure (e.g., screw caps)
Obtain additional or large containers from the E,H&S Office.
NOTE: Large containers (>10 gal) on spill pallets require a drum jack to lift full drums.
Never overfill, as expansion and excess weight can lead to
spills, explosions, and chemical exposures.
Maximum Quantities
Hazardous – 55-gal in any combination of containers
Acutely hazardous – 1 quart of any one
CAUTION
Check chemical compatibility
before adding waste to a container

How Should the SAA
Look?
• LOCATION – same
room or suite where
waste is generated.
• Ideally in proper
storage cabinets or,
if on the floor, in an
isolated, low-traffic
area.
• Mark the designated
area with tape.
No Floor
Drains
A Note on Spill Pallets
Use of drum-sized
spill pallets requires
the purchase of a
portable drum jack to
lift and move full
drums.
