HCT Green Cleaning & Eco-Friendly Practices 2 — Questions and Answers
Question 1: Baking soda is commonly used as an eco-friendly cleaning agent because it:
- Is highly acidic and dissolves metals
- Acts as a mild abrasive and odor absorber with low environmental toxicity (Correct answer)
- Contains chlorine for disinfection
- Requires no water to activate
Correct answer: Acts as a mild abrasive and odor absorber with low environmental toxicity
Baking soda's mild abrasiveness makes it effective for scrubbing without scratching, and its alkaline nature neutralizes acidic odors.
Question 2: Which of the following should a green cleaning technician avoid when selecting cleaning products?
- Products with biodegradable surfactants
- Products containing phosphates, as they contribute to aquatic ecosystem damage (Correct answer)
- Products with plant-derived ingredients
- Products with EPA Safer Choice certification
Correct answer: Products containing phosphates, as they contribute to aquatic ecosystem damage
Phosphates entering waterways cause algal blooms that deplete oxygen and devastate aquatic ecosystems, which is why many states have banned them in cleaning products.
Question 3: Why is it important to properly dispose of single-use cleaning product containers rather than leaving them at the job site?
- Clients may reuse them for storage
- Responsible disposal reduces landfill waste and prevents chemical residue from harming the environment (Correct answer)
- Leaving containers at the site helps the client remember the product name
- Single-use containers are always recyclable
Correct answer: Responsible disposal reduces landfill waste and prevents chemical residue from harming the environment
Proper disposal prevents chemical residues from contaminating soil or water and reduces unnecessary plastic accumulation in landfills.
Question 4: Steam cleaning is considered an eco-friendly method primarily because it:
- Uses large amounts of industrial-grade chemicals
- Sanitizes using only high-temperature water vapor, eliminating the need for chemical disinfectants (Correct answer)
- Requires special disposal procedures for waste water
- Is only effective on tile surfaces
Correct answer: Sanitizes using only high-temperature water vapor, eliminating the need for chemical disinfectants
High-temperature steam kills bacteria and dissolves soil using only water, reducing chemical use and associated environmental impact.
Question 5: What is a Volatile Organic Compound (VOC) in the context of cleaning products, and why should technicians minimize their use?
- A stable compound that improves fragrance longevity
- A chemical that evaporates at room temperature and contributes to indoor air pollution and smog formation (Correct answer)
- A natural plant extract used as a preservative
- A mineral compound that improves cleaning power
Correct answer: A chemical that evaporates at room temperature and contributes to indoor air pollution and smog formation
VOCs evaporate into indoor air, causing respiratory irritation and contributing to outdoor smog when they escape through ventilation.
Question 6: How does choosing fragrance-free cleaning products benefit some residential clients?
- Fragrance-free products are always more powerful
- They reduce chemical exposure for clients with asthma, allergies, or chemical sensitivities (Correct answer)
- Unscented products dry surfaces faster
- Fragrance-free products cost significantly less
Correct answer: They reduce chemical exposure for clients with asthma, allergies, or chemical sensitivities
Many synthetic fragrances contain allergens or VOCs that trigger respiratory reactions in sensitive individuals, making fragrance-free options a health-conscious choice.
