Hazardous Materials Minimization
- Order only the exact volumes to be used.
- Work with your Procurement representative to monitor chemical purchases and avoid duplicate orders.
- When ordering chemicals, be aware of any properties that may prevent long term storage.
- Use suppliers who can provide quick delivery of small quantities.
- Promote sharing among common users.
- Rotate chemical stock to keep chemicals from becoming outdated.
- Locate surplus and unused chemicals, and then attempt to redistribute unused chemicals to other users.
- Attempt to return unused chemicals to vendor.
- Review experiment protocol to assure that chemical use is minimized.
- Microscale experiments using microtechnology wherever possible.
- Use less hazardous or non-hazardous substitutes when feasible.
- Instead of wet chemical techniques, use instrumental methods that will generally require smaller quantities of chemicals.
- Reuse spent solvent for initial cleaning, and then use fresh solvent only for final rinse.
- Substitute specialty detergents for sulfuric acid/chromic acid cleaning solutions.
- Distill and reuse solvents.
- Avoid mixing hazardous and non-hazardous waste.
- Review literature for additional techniques applicable to your particular processes.
