Are microwave devices properly ventilated?
Note: Microwave devices should be placed in an appropriate ventilation hood to contain airborne chemical contaminants and potentially infectious agents. Microwave devices used outside a fume hood should have an integral fume extractor that is certified by the manufacturer for use in a clinical laboratory. This checklist question does not apply if only non-hazardous reagents are used in the device (e.g., water, certain biological stains).
