Case Study – Filling Corrosive and Toxic Liquids

Fume Booth Filler for Drum and TotesA chemical manufacturer asked us to solve a problem filling 30-gallon carboys and 55-gallon drums on a pallet as well as 330-gallon totes with toxic and corrosive chemicals. The liquid caused a safety hazard for the operator and the surrounding work area. Curtains, gloves, masks, and other solutions tried by the customer were not effective enough.

The Customer

The customer is a world-wide manufacturer of cleaning liquids. Buying capital equipment from the lowest bidder forced them to live with their problems until they learned that Specialty Equipment solves unique issues and is the leading manufacturer in handling hazardous chemicals.

The Challenge

The most obvious challenge was to provide absolute safety for the operator from highly toxic fumes and prevent them from going airborne. The acid splash-back and overfilling problems also added to the safety issues.

The Solution

We created a special, all-stainless steel construction, two-room, fume booth that included a nitrogen purging station to clean out the container prior to filling it, a semi-automatic drum and tote filling station, and a bung and capping station. Two pairs of rubber gloves are provided for the operator for removing bungs from drums and totes, both at the purging station, then a similar pair of gloves at the filling station for replacing the bungs after filling the container. A special pivoting bellows was included for leaning into the booth to bung and cap.
