    When pouring acetone waste into a satellite drum, can we just ground the drum or do we have to ground both the container with the acetone and the drum?

      Hi there, thanks for asking! In a satellite accumulation area, if you are collecting acetone waste, the drum should be grounded and the container that you are pouring the waste acetone from should be bonded to the funnel or bung opening of the collection drum. Grounding the drum channels residual electrical energy, and bonding completes the circuit to help ensure safety while the waste acetone is being transferred from one container to the other.

    What if you have a metal safety container full of Toluene, and then you are dispensing it into a plastic container. Do you still put the bonding cable on the plastic container?

      Hi there,

      Chances are, you won’t be able to bond this system because plastic containers cannot be bonded or grounded. There are some plastic containers on the market that have been specifically treated to be conductive. This is usually done by incorporating a metal mesh frame or flakes/bits/strips of metal into the plastic container. If the container is conductive, it typically says this somewhere on the container and there will be a tab, loop, screw or other metal feature to facilitate grounding.

      Thanks for your question,

    When transferring materials like acetone from one metal drum to another metal drum. By way of pneumatic or diaphragm pumps. Should both drums be grounded or is it best to only do the receiving drum?

      Hi there,

      OSHA says the following in regards to grounding in the general industry standards:

      “Grounding. Category 1 or 2 flammable liquids, or Category 3 flammable liquids with a flashpoint below 100 °F (37.8 °C), shall not be dispensed into containers unless the nozzle and container are electrically interconnected. Where the metallic floorplate on which the container stands while filling is electrically connected to the fill stem or where the fill stem is bonded to the container during filling operations by means of a bond wire, the provisions of this section shall be deemed to have been complied with.”

      This means all containers of Category 1, 2 or 3 liquids (liquids with a flashpoint lower than 100°F) need to be bonded and grounded during dispensing. This includes non-metallic containers, even though the construction material may not be recognized as conductive (for example, polyethylene).

      If the containers are not properly bonded and grounded, the resulting static spark could be capable of raising the vapor temperature above the flashpoint, causing an explosion.

      Where you are located may have adopted National Fire Protection Association (NFPA) 30 and 77 or International Fire Code (IFC) 5003.9.5 requirements. These may have more stringent requirements that you are required to follow. Your local authority having jurisdiction (usually a fire marshal) will be able to determine if your location has adopted NFPA or IFC requirements. It would also be the best management practice (BMP) to bond and ground every object involved in transferring flammable liquids, even for flammable liquids with a flashpoint above 100°F.

      Thanks and I hope this helps!
