The attached haz waste procedure appears to be very good with one additional precaution: Bond any metal items that go into the waste drum to prevent a spark, which could ignite any flammable vapors that evolve from the waste drum. Wikipedia has a brief description at: Electrical Bonding, although it only briefly mentions the importance of electrical bonding in preventing ignition of flammable vapors in aircraft fuel tanks. Many fires have occurred when filling gasoline containers.

This is a very common waste stream in academia and industry and I have used the following system in both:
- Set up a satellite accumulation area in a convenient lab location utilizing an 8 gallon DOT approved drum
- Set the drum on a spill pallet and label with the hazardous waste contained therein
-Ground the drum
-Prepare a weekly inspection form binder for the lab
-When the drum is full, the lab can cap and date the drum and have someone haz waste trained move the drum to 90/180 day storage; or, contact your haz waste vendor to move the drum to storage (you have 72 hours to do this) and I have done it both ways
-replace the full drum with a new empty

This completely eliminates the need for anyone to stand around pouring off 5 gallon containers of haz waste into drums (high exposure potential activity) so no one needs a respirator. The lab just needs their annual generator training and the people handling the drums need their annual training. Smaller organizations without a haz waste technician (or bigger organizations with a responsive contractor) can utilize their vendor to come and move the drums so no one needs that higher level of training. Like I said, I have done it both ways and I actually like the vendor doing it because they are pros at moving drums and they provide all their training documentation.

My life is not a waste but waste is my life.....

We routinely collect liquid hazardous waste in 5-gall containers in our laboratories. This waste stream primarily consists of flammable solvents and water. Full containers are moved to our bulk haz waste accumulation room and transferred to 55 gall drums. The 5-gall containers are very heavy so lifting/pouring can easily lead to spills. We have found that hand pumps also tend to be messy. Does anyone use a mechanical pump (intrinsically safe, possibly air driven, or other) to manage this type of transfer?
