CMI Environmental Sustainability & Compliance 2 — Questions and Answers
Question 1: Which EPA program regulates the disposal of used cleaning solvents classified as hazardous waste?
- RCRA (Resource Conservation and Recovery Act) (Correct answer)
- TSCA (Toxic Substances Control Act)
- CERCLA (Superfund)
- FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act)
Correct answer: RCRA (Resource Conservation and Recovery Act)
RCRA governs the generation, storage, treatment, and disposal of hazardous waste, including used cleaning solvents.
Question 2: What does the term 'carbon footprint' specifically measure in a cleaning operation?
- Total water consumption per square foot cleaned
- Total greenhouse gas emissions expressed in CO2 equivalents (Correct answer)
- Amount of chemical waste sent to landfill
- Energy cost per cleaning shift
Correct answer: Total greenhouse gas emissions expressed in CO2 equivalents
Carbon footprint measures all greenhouse gas emissions (CO2, methane, nitrous oxide, etc.) converted to CO2 equivalents.
Question 3: A cleaning company wants to reduce VOC emissions from floor finish products. Which approach is most effective?
- Apply thicker coats less frequently
- Switch to waterborne, low-VOC or zero-VOC formulations (Correct answer)
- Increase ventilation during application only
- Use oil-based finishes with slower cure times
Correct answer: Switch to waterborne, low-VOC or zero-VOC formulations
Waterborne low-VOC formulations contain fewer volatile organic compounds that off-gas into indoor and outdoor air.
Question 4: Under the Clean Air Act, which indoor cleaning product category is most likely to trigger VOC content limits?
- Microfiber mops
- Aerosol disinfectant sprays (Correct answer)
- HEPA vacuum bags
- Color-coded cleaning cloths
Correct answer: Aerosol disinfectant sprays
Aerosol spray products release propellants and chemical solvents that contribute to VOC emissions regulated under the Clean Air Act.
Question 5: What is 'greenwashing' in the context of cleaning product marketing?
- Using green-colored packaging for all eco-friendly products
- Making misleading or unsubstantiated environmental claims about a product (Correct answer)
- Washing surfaces with plant-based soap solutions
- Certifying products through third-party green certification programs
Correct answer: Making misleading or unsubstantiated environmental claims about a product
Greenwashing refers to deceptive marketing that exaggerates or fabricates environmental benefits of a product.
Question 6: Which of the following best describes a 'closed-loop' water recycling system in a commercial cleaning operation?
- A system where wastewater is treated and reused on-site rather than discharged (Correct answer)
- A system that only uses rainwater collected from the roof
- A billing model where water costs are built into the cleaning contract
- A vacuum system that captures moisture before it reaches the drain
Correct answer: A system where wastewater is treated and reused on-site rather than discharged
A closed-loop system captures, treats, and recirculates wastewater, reducing total water consumption and discharge.
Question 7: When a cleaning chemical SDS lists an ingredient as a 'persistent bioaccumulative toxin (PBT),' what does this mean for sustainability?
- The chemical breaks down quickly in the environment
- The chemical accumulates in living organisms and persists in the environment long-term (Correct answer)
- The chemical requires special cold storage to remain effective
- The chemical is only toxic at very high concentrations
Correct answer: The chemical accumulates in living organisms and persists in the environment long-term
PBTs resist environmental degradation and build up in the food chain, posing long-term ecological risks.
