In a well-maintained work area spills of hazardous materials are cleaned up at the time of their release. Even small spills must be cleaned up immediately since they can add to personal exposures through inhalation or skin absorption. Frequent handwashing should become routine, especially after handling hazardous materials and before leaving the lab. Handwashing is necessary even with diligent glove use to remove traces of inapparent contamination. Food and drink brought into areas of chemical or radiological use can easily become contaminated by these hazards.
Airborne particulates can settle on exposed food, eating surfaces or utensils.
Even though work surface contamination may not be readily apparent, it can adhere to hands and then be transferred to food items. Upon ingestion these harmful substances will be carried into the body, increasing the opportunity for toxic effects. Sanitation Standard regulates the use of toxic materials in eating and drinking in areas. All labs must have a record of monthly wipe tests and Geiger meter surveys for review by Radiation Safety.
