I would appreciate your feedback on my situation. We have recently replaced our single satellite accumulation container that was a 5-gallon metal drum to 2 separate plastic (UN approved) translucent "drums". This was at the suggestion of one of the environmental coordinators at the site. Now the other environmental coordinator & the "fire guy" are saying this is unacceptable because we cannot ground the plastic containers. We only use glass beakers or flasks to pour waste into these containers or it is waste going directly into a container from a HPLC (essentially a closed system).
Is this really a "fire risk"? I recognize that there may be a small potential for static to build in a plastic container, but we are not really "transferring or dispensing" from these containers in the traditional sense. The original starting materials are purchased in plastic 4L containers or glass containers which cannot be grounded when pouring out of either. I am having a hard time understanding the push to go back to a metal container just so we can ground it. I will add that the plastic gives us the ability to see the volume of liquid in the container so we will not over-fill it.
Thoughts on how to handle this? The plastic containers meet the requirements for the waste as per NFPA/DOT so it is just a question of fire risk.
Thanks for your input!
