Which of the following chemicals must NOT be stored together due to the risk of forming shock-sensitive explosive compounds?
Answer: Ammonia and bleach (sodium hypochlorite)
Ammonia and bleach react to form chloramine gases and, in concentrated forms, can produce nitrogen trichloride, which is explosive and toxic.
Under RCRA, what is the required aisle space between containers in a hazardous waste storage area?
Answer: At least 2 feet wide to allow inspection and emergency access
40 CFR 265.35 requires that sufficient aisle space be maintained to allow unobstructed movement of personnel and emergency equipment, and EPA guidance specifies at least 2-foot aisles.
What is the primary reason that oxidizers must be stored separately from flammable and combustible materials?
Answer: Oxidizers supply oxygen that can intensify or initiate combustion of nearby flammables
Oxidizers release oxygen, which can dramatically accelerate combustion and turn otherwise manageable fires into severe hazards when flammables are nearby.
A facility discovers that a hazardous waste storage container has begun to leak. Under RCRA interim status standards, the facility must:
Answer: Transfer the waste to a new container immediately or overpak the leaking container
40 CFR 265.171 requires that leaking containers be immediately transferred to good containers or overpackaged to prevent releases.
Which label element is specifically required on hazardous waste containers at the point of accumulation under RCRA?
Answer: The words 'Hazardous Waste' and the accumulation start date
RCRA requires containers to be labeled 'Hazardous Waste' and marked with the date accumulation began, among other required information.
Under NFPA 30, the maximum quantity of flammable liquids (Class I) that may be stored in a flammable storage cabinet is:
Answer: 60 gallons
NFPA 30 and OSHA 1910.106 limit each flammable storage cabinet to no more than 60 gallons of Class I and II liquids combined.
Which storage scenario would trigger EPA's Risk Management Program (RMP) requirements under 40 CFR Part 68?
Answer: Storing 10,000 lbs of anhydrous ammonia at a food processing plant above the 10,000 lb threshold
RMP is triggered when a regulated substance is present above its threshold quantity; anhydrous ammonia has a 10,000 lb threshold and food processing is not exempt.
