CMI Compliance with Environmental Sustainability Standards 4 — Questions and Answers
Question 1: Which government agency administers the Design for the Environment (DfE) program that helps custodians identify safer cleaning products?
- U.S. Environmental Protection Agency (EPA) (Correct answer)
- Occupational Safety and Health Administration (OSHA)
- Department of Labor
- National Institute for Occupational Safety and Health (NIOSH)
Correct answer: U.S. Environmental Protection Agency (EPA)
The EPA's Design for the Environment (now Safer Choice) program evaluates and certifies cleaning products with safer chemical formulations.
Question 2: A facility manager asks custodians to implement 'green cleaning' protocols. Which is NOT typically a component of a green cleaning program?
- Using the strongest available disinfectant for all surfaces daily (Correct answer)
- Selecting EPA Safer Choice certified products
- Training staff on proper dilution ratios
- Using microfiber equipment to reduce chemical usage
Correct answer: Using the strongest available disinfectant for all surfaces daily
Green cleaning emphasizes using the least hazardous effective product for each task, not applying the strongest chemicals universally.
Question 3: What information found on a Safety Data Sheet (SDS) is most relevant to environmental compliance?
- Section 12: Ecological Information (Correct answer)
- Section 1: Identification
- Section 4: First-Aid Measures
- Section 7: Handling and Storage
Correct answer: Section 12: Ecological Information
Section 12 of the SDS provides ecological information including aquatic toxicity, persistence, bioaccumulation, and mobility in soil.
Question 4: A custodian is using a chemical that requires PPE. After the task, how should the used PPE be handled to minimize environmental impact?
- Clean reusable PPE per manufacturer instructions; dispose of contaminated single-use PPE per hazardous waste guidelines (Correct answer)
- Rinse all PPE with water and place in regular trash
- Burn disposable PPE to prevent chemical spread
- Leave PPE in a ventilated area to off-gas before disposal
Correct answer: Clean reusable PPE per manufacturer instructions; dispose of contaminated single-use PPE per hazardous waste guidelines
Reusable PPE should be properly cleaned, while contaminated single-use PPE must be disposed of following hazardous waste regulations to prevent environmental contamination.
Question 5: Which of the following best describes 'life cycle assessment' as it applies to custodial product selection?
- Evaluating a product's environmental impact from raw material extraction through disposal (Correct answer)
- Checking how long a cleaning product remains effective on a shelf
- Measuring how many square feet a product can clean per gallon
- Assessing how quickly a product biodegrades in water
Correct answer: Evaluating a product's environmental impact from raw material extraction through disposal
Life cycle assessment (LCA) examines all environmental impacts of a product from manufacturing through end-of-life, enabling more sustainable purchasing decisions.
Question 6: A hospital custodial department wants to reduce its carbon footprint. Which change has the greatest potential impact?
- Switching to concentrated, locally-sourced cleaning products with recyclable packaging (Correct answer)
- Replacing white mop heads with green mop heads
- Increasing cleaning frequency to reduce pathogen load
- Using warm instead of hot water for mopping
Correct answer: Switching to concentrated, locally-sourced cleaning products with recyclable packaging
Concentrated products reduce shipping weight and emissions, local sourcing cuts transportation miles, and recyclable packaging reduces manufacturing energy for new containers.
Question 7: What is the correct procedure when a custodian accidentally over-dilutes a cleaning chemical, making it weaker than recommended?
- Properly dispose of the diluted solution and prepare a fresh, correctly diluted batch (Correct answer)
- Add more concentrate to the bucket to correct the ratio
- Use the weaker solution but apply more and increase dwell time
- Return the solution to the concentrate container
Correct answer: Properly dispose of the diluted solution and prepare a fresh, correctly diluted batch
The safest and most compliant procedure is to properly dispose of the incorrectly mixed solution and prepare a new batch at the correct dilution ratio.
