A neighbouring lab which I have recently become responsible for uses chloroform as part of tissue processing - in an enclosed processor.
Although the lab I started in (20 years ago) used chloroform, all of the labs I have worked in since have used xylene. 
I am aware of the health hazards of using xylene, and the measures used to reduce them, but I am not familiar with the hazards of using chloroform - though I am obviously aware that it can produce phosgene and is carcinogenic. 
Does anyone, especially in the UK have any thoughts on this, especially as we are about to submit a CPA application. 
Thanks
