(b)

(1) Grinding or compacting may be used when it is an integral part of an alternative treatment method approved by the department.

A compactor may be used to compact medical waste if the type of medical waste compactor proposed to be used is evaluated by the department, and approved by the department prior to its use pursuant to the following criteria:

(A)

The compactor operates without the release of liquids or pathogenic microorganisms from the medical waste during placement of the medical waste into, or removal of the medical waste from, the compactor units, and during the compaction process.

The compacted medical waste will not release liquids or pathogens during any subsequent handling and no residual waste will be left in the compactor unit after the process is completed.

(C)

Compactor operations and maintenance personnel will not be at any substantial increased risk of exposure to pathogens.

Medical waste in bags or other containers shall not be subject to compaction by any compacting device and shall not be placed for storage or transport in a portable or mobile trash compactor, except as allowed pursuant to subdivision (b).
