What is the purpose of a 'contingency plan' required for large quantity generator hazardous waste storage areas?
Answer: To describe emergency response actions for fires, explosions, or unplanned releases
The contingency plan required under 40 CFR 265 Subpart D describes emergency response procedures for fires, explosions, and unplanned releases of hazardous waste.
Corrosive hazardous materials should be stored at low levels (bottom shelves or floor) primarily because:
Answer: A spill from a high location increases splash exposure and the area of contamination
Storing corrosives at low levels minimizes the splash radius and worker exposure risk if a container is dropped or falls.
Under DOT Hazardous Materials Regulations, which packaging group indicates the highest level of danger and most stringent storage requirements?
Answer: Packing Group I
DOT Packing Group I designates materials with the greatest danger, requiring the most stringent packaging and handling controls.
When a small quantity generator (SQG) exceeds the 6,000 kg on-site accumulation limit, what is the regulatory consequence?
Answer: The generator immediately becomes subject to large quantity generator requirements
If an SQG accumulates more than 6,000 kg on-site, it is immediately subject to LQG requirements for that month.
Which of the following is a correct practice for storing compressed gas cylinders in a hazardous materials storage area?
Answer: Securing cylinders upright with chains or straps and separating by gas type
Compressed gas cylinders must be stored upright, secured against falling, and segregated by gas type (e.g., oxidizers away from flammables).
A facility stores both regulated medical waste and RCRA hazardous waste. Which statement about commingling these waste streams is correct?
Answer: Mixing regulated medical waste with RCRA hazardous waste makes the entire mixture subject to RCRA hazardous waste regulations
If regulated medical waste is mixed with RCRA hazardous waste, the mixture is regulated as RCRA hazardous waste and all RCRA storage requirements apply.
Under OSHA 29 CFR 1910.1200 (Hazard Communication), what must be posted or immediately available in a hazardous materials storage area?
Answer: Safety Data Sheets (SDS) for all hazardous chemicals present
OSHA Hazard Communication requires that SDS for all hazardous chemicals be readily accessible to employees in their work area, including storage areas.
