Mixing of chemicals for disposal.
This is a good question - when I started this job the guy in Risk 
Management told me to mix all the waste solvents together for disposal. 
They come by once a month and pick up all this stuff. In previous labs I 
had to keep formalin separate from alcohols and xylene and acids. Is this a 
policy that changes from locale to locale or is there some "national" 
regulation on disposal of these chemicals?
