RE: [Histonet] NCCLS Microwave Device Use Proposed Guideline

From:"Willis, Donna"

It is against OSHA guideline (OSHA 29 CFR 1910.303(b)(2))to use a commercial
microwave (exp. Wal-Mart).  The warranty of commercial units state that the
instrument is not to be used for anything except its original use, food
preparation.  The OSHA guideline would include any equipment in the lab.  If
someone gets injured the lab would be at fault not the manufacture.

Subject: [Histonet] NCCLS Microwave Device Use Proposed Guideline

I have the GP28-P guideline and read it but am unsure about its
recommendations or limitations in using a microwave for special stains only.

Is there any consensus among histology labs as to its interpretation? Is it
still OK to use a commercial microwave from Wal-Mart without special exhaust
system as long as you don't microwave formaldehyde, osmium tetroxide, lead
acetate etc. (Paragraph 4.4) and do annual leakage tests?
