Environmental Contamination

Avoiding Environmental Contamination

1. Teflon coat or epoxy paint the (hopefully few) metal objects in the laboratory. Epoxy paint the walls. Walls should be washed down weekly and repainted annually.
2. Use special adhesive floor pads for all openings to the laboratory.
3. Use disposable plastic gloves and disposable paper laboratory coats.
4. Vinyl covered floors should be mopped daily. Floors with drains allow for easier daily washing.
