Eating, drinking, food storage, application of cosmetics, and handling of contact lenses in research laboratories is permitted only in approved, posted Clean Areas.
Designate a Clean Area
When required by space considerations, Clean Areas may be designated within lab areas containing desks, writing tables, or food refrigerators.
The area must be:
- Physically separated from any laboratory work area by at least one meter, or by a substantial physical barrier such as a solid bookcase or an acrylic shield
- Approved by Environment, Health & Safety (EH&S)
- Contact the EH&S Research Safety Program specialist for your building to get approval
- Posted with a Clean Area sign
- Equipped with a waste receptacle for non-laboratory trash only
Freezers and refrigerators in labs
Prevent the ingestion of chemicals, biological agents and radioactive materials. Avoid storing food in refrigerators and freezers.
- Print and post a clear warning sign on lab refrigerators and freezers to warn lab personnel: (PDF) (Word file)
- Assign a responsible person to check periodically and make sure there's no food stored in these areas.
Protect Clean Areas from contamination
- Remove gloves and wash your hands after working with hazardous materials and before working in a Clean Area. Do not rely on hand sanitizers to clean your hands.
- Conduct routine laboratory surveys within and at the boundaries of Clean Areas to detect radioactive contamination.
