Hand Clamp Clamp and Alligator Clip ‘C’ Static hazards may also exist in non-metallic plastic or glass containers that cannot be grounded. Static may be generated by the free fall and turbulence of the liquid being poured. To minimize this hazard, pour as slowly as possible and use a grounded nozzle extension that allows filling the container from the bottom. DISPENSING FLAMMABLE LIQUIDS FROM 5 GALLON PAILS Manual dispensing pumps for 5-gallon pails/cans are available. These pumps are specifically designed to dispense liquids into small laboratory-size bottles without spilling. If you are pouring into a conductive container, a bonding wire should be attached from the 5-gallon pail to the container being filled. The 5-gallon pail should be grounded. The dispenser shown in the picture below can be purchased through Fisher Scientific . The metal strap in the picture hooks over the bottom of the pail and secures the dispenser while pumping. Metal Strap Two adapters are provided with the dispensing pump from Fisher (grey and black). Use the appropriate adapter to achieve the correct seal with the solvent container you have. Some solvent containers have a grey fitting at the opening, and others have a black one. DISPENSING FLAMMABLES FROM SAFETY CANS Safety cans have self-closing air tight lids and a flame arrestor that protects the contents from an external ignition source. Bonding and grounding is still required on safety cans since static electricity generation is possible. The nozzle provides a bonding path to a receiving metallic vessel.
