CMI Environmental Sustainability & Compliance 5 — Questions and Answers
Question 1: A cleaning contractor is transitioning to a 'no-mop' floor cleaning system using flat microfiber pads. Which sustainability outcome is most likely?
- Increased chemical usage due to less effective soil removal
- Reduced water consumption and chemical use per square foot cleaned (Correct answer)
- Higher labor costs due to more frequent pad changes
- Greater landfill waste from disposable pad systems
Correct answer: Reduced water consumption and chemical use per square foot cleaned
Flat microfiber pad systems require significantly less water and cleaning solution than traditional mop-and-bucket methods.
Question 2: Which federal standard requires cleaning product manufacturers to label containers with hazard information to protect workers and the environment?
- EPA's National Pollutant Discharge Elimination System (NPDES)
- OSHA's Hazard Communication Standard (HCS/HazCom) and GHS alignment (Correct answer)
- TSCA Section 8(e) substantial risk notification
- DOT 49 CFR hazardous materials transportation rules
Correct answer: OSHA's Hazard Communication Standard (HCS/HazCom) and GHS alignment
OSHA's HazCom Standard (aligned with GHS) requires manufacturers to provide SDS and labels with hazard, environmental, and handling information.
Question 3: A facility's green cleaning policy prohibits products containing triclosan. What is the primary environmental concern with triclosan?
- It evaporates rapidly and contributes to ozone depletion
- It is persistent in aquatic environments and may contribute to antimicrobial resistance (Correct answer)
- It reacts with chlorine to form highly flammable compounds
- It degrades HEPA filter media, reducing vacuum efficiency
Correct answer: It is persistent in aquatic environments and may contribute to antimicrobial resistance
Triclosan persists in waterways, accumulates in aquatic organisms, and may promote antimicrobial resistance in microbial populations.
Question 4: In a waste audit of a hotel's housekeeping department, which waste stream would be best addressed by implementing a linen reuse program?
- Chemical container waste
- Solid textile and water waste from daily linen laundering (Correct answer)
- Food waste from in-room dining service
- Electronic waste from replacing minibars
Correct answer: Solid textile and water waste from daily linen laundering
Daily linen changes generate significant water, energy, chemical, and textile waste; reuse programs dramatically reduce this environmental impact.
Question 5: Which of the following best describes the EPA's Safer Choice label on a cleaning product?
- The product has been tested and found to kill 99.9% of bacteria
- Every ingredient in the product has been evaluated and found safer for human health and the environment (Correct answer)
- The product's packaging is made from 100% post-consumer recycled materials
- The product meets OSHA permissible exposure limits for worker safety
Correct answer: Every ingredient in the product has been evaluated and found safer for human health and the environment
EPA Safer Choice evaluates every ingredient in a formulation for human and environmental safety before awarding the label.
Question 6: When implementing an environmental management system (EMS) based on ISO 14001, what is the first step a cleaning organization must complete?
- Purchase ISO 14001-certified cleaning products immediately
- Conduct an environmental aspects and impacts assessment of all cleaning activities (Correct answer)
- Register the company with the EPA as a certified green contractor
- Train all cleaning staff in LEED custodial certification
Correct answer: Conduct an environmental aspects and impacts assessment of all cleaning activities
ISO 14001 requires organizations to first identify their environmental aspects (activities) and evaluate their associated impacts before setting objectives.
Question 7: A commercial cleaning company wants to reduce packaging waste from chemical procurement. Which purchasing strategy achieves the greatest reduction?
- Purchasing pre-measured single-dose chemical packets for each cleaning task
- Using a chemical dispensing system with concentrated refillable containers (Correct answer)
- Buying chemicals in standard one-gallon jugs instead of quart bottles
- Sourcing products from local manufacturers to reduce shipping distance
Correct answer: Using a chemical dispensing system with concentrated refillable containers
Dispensing systems with concentrated refillable containers eliminate repetitive packaging waste by reusing the same container with minimal concentrate deliveries.
