Container Management

Hazardous Waste Container Requirements:

• Container Condition and Compatibility:
• Hazardous waste must be collected in structurally sound containers that are compatible with the waste being stored.
• Containers must be kept tightly closed at all times except when waste is actively being added.
• Use of Funnels:
• If a funnel is used to fill a container, it must either be removed and the container tightly closed when not in use, or the funnel must be securely attached to the container’s bung hole and equipped with a cover that can be tightly closed.
• Proper Labeling:
• Containers must be clearly labeled with:
• The words "Hazardous Waste".
• The proper chemical name(s) of the waste inside.
• The associated hazards (e.g., flammable, corrosive).
• Labels can be provided by Environmental, Health, and Safety (EHS) upon request.
• Storage Surface and Separation:
• Containers must be placed on impenetrable surfaces to prevent contamination in case of leaks.
• Wastes must be kept separate from incompatible materials and chemicals.
• Physical barriers such as dikes, berms, or walls may be required to ensure safe segregation.
• Weekly Inspections:
• A trained laboratory worker must inspect the containers weekly for signs of deterioration or leaks.
• Damaged containers must be promptly repaired or replaced to prevent hazards.
• Date Marking When Full:
• When a container reaches its capacity, it must be marked immediately with the date it became full.
• A new waste container may be started during this 72-hour period.
• Timely Removal:
• Full containers must be relocated to the designated accumulation area within three days.
