Container Selection


Proper container selection is critical for the safe handling, storage, and accumulation of hazardous materials. The following guidelines ensure compliance with safety standards and reduce risks:

Container Material
  • Use containers made of materials compatible with the hazardous material being stored. Ensure the container is resistant to chemical reactions or degradation.
  • Prohibited: Do not use food or beverage containers to store hazardous materials, even temporarily. This prevents accidental ingestion or misuse.
Caps and Closures
  • Containers must have tightly fitting, screw-top caps. Avoid containers with snap-on or loose-fitting lids, as they do not provide adequate containment for hazardous substances.
Preferred Containers
  • Plastic or plastic-coated glass containers are strongly recommended for storing hazardous liquids. These materials are durable, resistant to breakage, and provide secondary containment in case of spills.
Maximum Container Size (Excluding Drums)
  • The maximum allowable size for filling containers is 2.5 gallons, excluding drums. This limitation ensures manageable handling, reduces the risk of spills, and aligns with safe storage practices. For larger storage needs, use approved drums or bulk containers as directed by EHS.
Labeling Requirements
  • All containers must be clearly labeled with the contents and associated hazards. Use appropriate chemical waste labels provided by Environmental Health & Safety (EHS).
Inspection and Maintenance
  • Regularly inspect containers for signs of wear, damage, or leaks. Replace damaged containers immediately to maintain a safe environment.
