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 are able to identify any conditions present that could contribute to a fire hazard.
The results of each DHA affects how facility managers move forward with operations. If the DHA reveals dust build-up, effective processes are necessary to properly follow-up on the results and maintain compliance to the NFPA 652 standard. Solutions must be put in place to improve the cleanliness of the facility and mitigate combustible dust risk. This final step of the DHA is a crucial component of NFPA 652 compliance. Specific recommendations are important to properly address the hazard and demonstrate recognizable efforts to manage risk.
These efforts must be documented and completed in a timely manner to comply with NFPA 652. As processes are implemented, the DHA must be updated regularly to reflect new equipment or procedural changes within a manufacturing facility. Per the NFPA standard, this analysis must be reviewed every five years to maintain compliance. These ongoing requirements make effective, long-term solutions to dust hazard mitigation a high priority for facility managers. NFPA 652 goes on to include recommendations for such solutions.
NPFA 652 Now Incorporates Dust Control Fans as Effective Mitigation Solution
As of 2019, section 9 of NFPA 652 identifies dust control fans as an effective measure to comply with the standard. The standard permits the use of these fan systems, such as those made by SonicAire, to limit dust accumulation in elevated areas and properly mitigate combustible dust risk.
How Dust Control Fans Work
Dust control fans are a proven method to maintain clean overhead areas. This technology controls dust flow and effectively eliminates dust concerns in these areas. How? The fans robotically prevent the accumulation of dust on surfaces and in the air, which mitigates the risk of combustible dust events.
Specifically, SonicAire’s industrial dust control fans use patented BarrierAire™ automation technology to control dust flow. SonicAire is the industry leader in dust control fan innovations, and this technology has become a go-to solution to prevent dust from accumulating in overhead areas. High velocity, high mass airflow from an automated SonicAire fan creates an overhead air barrier. This BarrierAire™ technology controls the direction of the dust and forces it to the floor by preventing upward currents and stagnant air that keeps dust in suspension, preventing accumulation of fugitive dust in overhead and hard-to-reach places and maintaining NFPA 652 compliance.
Dust Control Fan Installation
Because each facility is unique, SonicAire dust control fans are designed as a custom installation that produces optimal results at each industrial manufacturing setting. Fan installations are engineered based on the size and shape of the facility, its operations, dust type generated (wood, paper, plastic, recycling, glass, grain, nonwoven lint, etc.) and any other factors that may influence dust accumulation.
Installation options include variable speed control, automatic control timers and process interlock control options. Because the fans feature top-to-bottom cleaning ranges of 0° to 140°, with full 360° oscillation, facility owners can be confident of achieving maximum efficiency and effectiveness.
