Why Avoid Toxic Cleaning Products?
Protect workers’ health Improve indoor air quality (IAQ)
Children = most vulnerable Reduce environmental impacts
Smog, ozone depletion, global warming Toxicity to fish, wildlife

Health Hazards of Cleaning Chemicals
~5 billion pounds used annually
6 out of every 100 janitors injured each year
20% of injuries are severe chemical burns to eyes/skin

What is “Green” Cleaning?
Products and practices that protect human health and environment Choosing safer products Reducing quantity of chemicals Minimizing exposure

Green Cleaners Save $
Opportunities to cut costs by: Reducing variety of products used Competitively bidding green cleaners Reducing amount of chemicals used via
best practices

Replace High Hazard Products
Floor strippers (asthma, burns) Disinfectants (asthma, organ poison) Degreasers/Solvents (cancer,
nerve damage) Acid toilet cleaner (burns) Metal polish (cancer, flammable) Graffiti/Paint Removers (cancer,
reproductive damage)

Low toxicity No cancer-causing ingredients Not corrosive to eyes or skin or skin sensitizer Won’t pollute air or deplete ozone layer Won’t kill fish Will biodegrade Low phosphorous Package recyclable Available as concentrate Limits on fragrances used Certain ingredients prohibited Performance tested Vendor training available
Choose Certified Green Cleaners

“Green Washing”
Discourage specification of industry self-certified “green” products Industry standards are usually
weaker than those set by independent third party organizations.
Avoid specification of products with single health- or environmental attribute (e.g., biodegradable)

Minimize Need for Harsh Cleaners
Assess: Where does dirt come from? Reduce Dirt: HEPA vacuums Prevent Mold and Mildew: Fix leaks,
eliminate moisture, ventilate Improve Interior Design: Door mats,
no wax floors

Dilute Properly
Use automatic dilution equipment Prevents exposure Saves money
Follow instructions Twice as much is NOT
twice as good

Try Microfiber
Cost-effective (life-cycle basis) Reduce chemical use (~1/2) Minimize water use (up to 95%) Prevent injuries (chemical exposure, back
strain, accidents) Effective (reduce dirt,
avoid cross-contamination)www.sustainablehospitals.org/PDF/tenreasonsmop.pdfwww.epa.gov/region09/waste/p2/projects/hospital/mops.pdf

Avoid Aerosols
Fine mist can penetrate lungs Propellants hazardous/flammable Cans may explode Expensive

Use Disinfectants Properly
All disinfectants are toxic (EPA-registered pesticides)
Disinfectants cannot be certified green Disinfectants should be…
Used only when needed Applied only after surface is cleaned Properly diluted Left on long enough to be effective
Look for peroxide-based products

Hawaii Pilot Test Health & Safety Improvements
Workers reported “green” floor strippers and disinfectants caused fewer breathing problems
Microfiber mops easier to push around than cotton mops
Green cleaners in no-spill containers
