Re: [Histonet] formalin disposal
Hello, We are also a small GI lab and we use HydeAway to neutralize our 10% NBF. After allowing to sit for the recommended amount of time we discard it down the drain flushing with plenty of water.

Re: [Histonet] FORMALIN DISPOSAL
You could try oxidizing formalin with 5% sodium hypochlorite to CO2 and formic acid, which in turn can be neutralized with sodium bicarbonate and poured down the drain. This can be performed under a regular fume hood which I assume is something you cannot do with a large drum. Of course disposal of tissues should be checked for compatibility with local regulations. cheers, Daniel - Daniel Prieto Laboratorio de Cultivo de Tejidos Departamento de Biologia Celular y Molecular Facultad de Ciencias - Universidad de la Republica Uruguay El 22/09/10 12:56, Sara Baldwin/mhhcc.org escribió: Histonetters: Our disposal company for formalin wants us to separate our stored tissues from the formalin and then pour the formalin into a drum.

RE: [Histonet] FORMALIN DISPOSAL
Our gross room is set up a with a fume hood that runs the entire length of one wall, this includes our sink. When we need to dump tissue, we plug the drain then lay down our formalin pads to collect any spills. We place a large specimen container on the pads add a large screen then pour off the formalin into the container. We use another container to collect the various parts and when full we cap it then place in the waste box that gets incinerated. The waste formalin is then de-formalized (Surgipath product), aldehyde and ph are check and if they pass we can then drain dispose. If not, we collect it as waste which is then stored in drums to be hauled away. This procedure was approved by our state DES. If you cannot dump the tissue under a hood like this, you will need to wear a chemical respirator, all of my staff have their own full face respirators and have been fit tested for them.

RE: [Histonet] FORMALIN DISPOSAL
Kathy, I'm not sure where you're located, but I am in California and we use a disposal company called Stericycle. They separate the waste for us and take both the specimens and formalin. I believe Stericycle works in other states besides California.
