The dust hazard analysis (DHA) requirements of NFPA 652 push manufacturers to assess the dust control situation at their facilities. By conducting a DHA, facility managers…
As an industry leader in chemical manufacturing, the corporation is dedicated to delivering sustainable solutions. To enhance the cleanliness, safety and efficiency of their plastics additives unit, they turned to SonicAire.
The production manager explains, “We installed two SonicAire industrial dust control fans in our charging station room. Here, we feed 2000 to 3000 kg of powder into our machines each hour. With this constant movement, powder particles inevitably accumulate in overhead areas. And with 25’ ceilings, this area was challenging to clean.”
Before SonicAire Fans: Combustible Dust Accumulation and High Cost
Before the SonicAire fans transformed their process, the plant spent $30K each year on manual housekeeping for this space. “To reach the overhead beams, we hired a pressure washing company,” the production manager reports. “They had to wash everything down manually, then use a vacuum truck to clear the floor. This required two to three days of down time on top of the cost of the service, and we had to do this three times each year to keep up with the dust accumulation.”
“All of our powder is white,” he notes. “Before the dust control fans were installed, you could see where the powder accumulated. Now, you don’t see any build-up. You can definitely see the difference.”
This clean atmosphere ensures OSHA compliance. It also offers a better first impression for the visitors who come through the facility.
The manager says, “We follow the standard of ‘dime-thickness’ accumulation, and our powder dust quickly built up to this level. Without the SonicAire fans, the combustible dust could get to that point or above before we could get the contractor here to clean it. Now, with the fans functioning, they keep us within compliance.”
