Overview

This video discusses the environmental and health risks associated with traditional petroleum-based solvents used in parts cleaning, highlighting their toxicity, contribution to air pollution, and potential harm to aquatic life. It introduces four best management practices (BMPs) to mitigate these risks: water-based cleaning systems, safer solvent alternatives, minimizing solvent use with safe practices, and spill preparedness. The video explores various water-based options like ultrasonic and steam cleaning, emphasizing proper wastewater management. It also details safer solvent choices, advising against chlorinated and highly volatile compounds, and provides guidance on identifying hazardous ingredients via Safety Data Sheets (SDS). Finally, it stresses the importance of proper handling, storage, spill prevention, and staff training to protect both human health and the environment, encouraging viewers to contact EcoBiz for further assistance and resources.

Chapters

  • •Petroleum-based solvents are effective but pose significant environmental and health risks.
  • •Health impacts include cancer, central nervous system damage, and irritation to lungs, skin, and eyes.
  • •Solvents contribute to smog, poor air quality, and harm aquatic life.
  • •Chlorinated solvents are persistent pollutants and are prohibited by EcoBiz certification.
  • •Four key BMP areas are introduced to minimize risks.
  • •These include water-based cleaning systems, safer solvent alternatives, minimizing solvent use, and spill preparedness.
  • •The goal is to reduce exposure and environmental contamination.
  • •Alternatives include bio-based/water-based part washers, spray cabinets, steam cleaning, and ultrasonic cleaning.
  • •Pre-cleaning and regular maintenance (oil skimmers, solids removal) extend solution life.
  • •Most systems generate wastewater requiring treatment; bio-based systems can be waste-free.
  • •Steam and ultrasonic cleaning offer effective cleaning but require careful condensate and wastewater management.
  • •Avoid halogenated solvents, high volatility solvents, and aromatic hydrocarbons (e.g., benzene, toluene).
  • •Check SDS Section 3 for ingredients like 'chlor' or 'bromopropane' to identify hazardous solvents.
  • •Opt for low VOC solvents (e.g., 50-state compliant) if petroleum-based solvents are necessary.
  • •Be cautious of wheel cleaners containing hydrofluoric acid or ammonium bifluoride due to severe burn risks.
  • •Always use the minimum amount of solvent needed and follow SDS for PPE.
  • •Minimize aerosol spray inhalation by spraying close to the part or into a rag.
  • •Keep parts washers closed when not in use to contain emissions and evaporation.
  • •Maximize solution life through pre-cleaning and a two-station cleaning approach.
  • •Never wash or rinse parts outdoors or discharge waste to storm drains.
  • •Ensure parts washers and cleaning areas are on impervious surfaces with secondary containment.
  • •Use drip pans during maintenance and fluid transfers.
  • •Clean up spills immediately and keep spill control equipment readily available.
  • •Train staff on spill prevention and response.

Key Takeaways

  1. 1Traditional petroleum-based solvents pose significant health and environmental hazards; safer alternatives are available and encouraged.
  2. 2EcoBiz certification prohibits the use of chlorinated solvents due to their persistence and toxicity.
  3. 3Water-based cleaning systems, when managed properly, offer a less hazardous alternative to solvent-based cleaning.
  4. 4Carefully review Safety Data Sheets (SDS) to identify and avoid toxic solvent ingredients like chlorinated compounds and aromatic hydrocarbons.
  5. 5Implementing safe use practices, such as minimizing solvent quantity and containing emissions, is crucial for reducing exposure.
  6. 6Robust spill prevention measures, including proper containment and immediate cleanup, are essential to protect local waterways.
  7. 7Proper wastewater treatment is required for most cleaning systems, with bio-based systems offering a potential zero-waste solution.
  8. 8Training staff on safe handling, use, and spill response is vital for compliance and environmental protection.
