Below are sample questions representative of the exercises included on this worksheet and related 6.8 Ethics, Waste, and Environmental Health in the Lab skill assessments:

Problem 1Difficulty: Mastery

A lab is preparing to ship preserved biological samples to another institution. Which statement best describes the ethical and environmental health responsibility?

AShip in any container as long as the lid is tight.

BRemove all labels so no one worries about hazards.

CAdd extra preservative until the sample jar is completely full with no air space.

DPackage and label according to shipping regulations, prevent leaks, and ensure the receiving lab can handle and dispose of preservatives and biohazards properly.

Solution & Explanation:Shipping hazards can create exposures and environmental releases during transit. Compliance, leak prevention, and coordination support safety and proper disposal.

Problem 2Difficulty: Mastery

A student sees a lab mate pour a disinfectant containing quaternary ammonium compounds into the sink every day. Which statement best describes the key issue to check?

AQuats are always safe because they are used in household cleaners.

BIf it foams, it is safe for the drain.

CWhether the product and concentration are approved for drain disposal locally; some compounds can harm aquatic life and wastewater processes, so policy and SDS guidance matter.

DDaily disposal is fine as long as the sink is rinsed afterward.

Solution & Explanation:Regular releases of some disinfectants can have environmental impacts. Ethical practice is to follow approved disposal guidance and minimize unnecessary discharge.

Problem 3Difficulty: Mastery

A lab discovers that a reagent supplier changed the formulation of a cleaning product, and the new version contains a hazardous solvent. Which statement best describes the most ethical lab response?

AContinue using it the same way because it has the same brand name.

BUpdate hazard assessments and disposal procedures (and retrain users) based on the new formulation rather than assuming the old safety plan still applies.

CIgnore the change because it is a “cleaning” product.

DPour leftover cleaner down the drain to avoid storing it.

Solution & Explanation:Ethical lab safety requires responding to new hazards. Changes in formulation can change exposure risks and waste classification.
