You need to review all of the notes that go with the standard:


NOTE: Microwave devices should be placed in an appropriate ventilation
hood to contain airborne

chemical contaminants and potentially infectious agents. Before
operation of the microwave device,

flammable and corrosive reagents should be removed from the hood, to
prevent fire or chemical

damage to the electronic components of the device. Microwave devices
used outside a fume hood

should have an integral fume extractor that is certified by the
manufacturer for use in a clinical


The effectiveness of ventilation should be monitored at least annually.

This checklist requirement does not apply if only non-hazardous reagents
(and non-infectious

specimens) are used in the device (e.g. water, certain biological
stains, paraffin sections). The

laboratory should consult the MSDS sheets received with reagents and
stains to assist in determining

proper handling requirements and safe use.

This checklist item does not apply to microwave devices that are
designed by the manufacturer to

operate without venting.


How much of this applies to you?  What are you microwaving? If it is
nonhazardous, as indicated above, then this is an N/A.

Or, is this a device designed to operate without venting?

If situation #1 above applies, then yes, you must comply.


Reading the detail in the notes is critical to understanding the
standards.  They are a lot more detailed and specific than what I have
seen in the past in other regulatory resources.
