CHMM Storage 4

Question 1

Which of the following chemicals must NOT be stored together due to the risk of forming shock-sensitive explosive compounds?

Accepted Answer

Ammonia and bleach (sodium hypochlorite)

Answer

Ammonia and bleach react to form chloramine gases and, in concentrated forms, can produce nitrogen trichloride, which is explosive and toxic.

Question 2

Under RCRA, what is the required aisle space between containers in a hazardous waste storage area?

Accepted Answer

At least 2 feet wide to allow inspection and emergency access

Answer

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.

Question 3

What is the primary reason that oxidizers must be stored separately from flammable and combustible materials?

Accepted Answer

Oxidizers supply oxygen that can intensify or initiate combustion of nearby flammables

Answer

Oxidizers release oxygen, which can dramatically accelerate combustion and turn otherwise manageable fires into severe hazards when flammables are nearby.

Question 4

A facility discovers that a hazardous waste storage container has begun to leak. Under RCRA interim status standards, the facility must:

Accepted Answer

Transfer the waste to a new container immediately or overpak the leaking container

Answer

40 CFR 265.171 requires that leaking containers be immediately transferred to good containers or overpackaged to prevent releases.

Question 5

Which label element is specifically required on hazardous waste containers at the point of accumulation under RCRA?

Accepted Answer

The words 'Hazardous Waste' and the accumulation start date

Answer

RCRA requires containers to be labeled 'Hazardous Waste' and marked with the date accumulation began, among other required information.
