Page 17 of 28 First Revision No. 20-NFPA 91-2013 [ New Section after A.3.3.2 ] A.3.3.3 Centralized Vacuum Cleaning System. This system normally consists of multiple hose connection stations hard-piped to an AMS located out of the hazardous area. Positive displacement or centrifugal AMDs can be used to provide the negative pressure air flow. The hoses and vacuum cleaning tools utilized with the system should be designed to be conductive or static-dissipative in order to minimize any risk of generating an ignition source. Low MIE materials should be given special consideration in the system design and use. A primary and secondary AMS separator combination (e.g., cyclone and filter receiver) can be used if large quantities of materials are involved. However, most filter receivers are capable of handling the high material loadings without the use of a cyclone. [ 654, 2013] Submittal Date: Fri Mar 01 12:04:55 EST 2013 Annex to FR-19-NFPA 91-2013.
Page 18 of 28 First Revision No. 22-NFPA 91-2013 [ New Section after A.3.3.2 ] A.3.3.4 Dust Collection System. A typical dust collection system consists of the following: (1) Hoods devices designed to contain, capture, and control the airborne dusts by using an induced air flow in close proximity to the point of dust generation (local exhaust zone) to entrain fugitive airborne dusts. (2) Ducting piping, tubing, fabricated duct, etc., used to provide the controlled pathway from the hoods to the dust collector (AMS). Maintaining adequate duct velocity (usually 4000 fpm or higher) is a key factor in the proper functioning of the system. (3) Dust collector an AMS designed to filter the conveyed dusts from the conveying air stream. Usually these devices have automatic methods for cleaning the filter media to allow extended use without blinding. In some systems, a scrubber or similar device is used in place of the filter unit. (4) Fan package an AMD designed to induce the air flow through the entire system. The system is designed to collect only suspended dusts at the point of generation and not dusts at rest on surfaces. The system is also not designed to convey large amounts of dusts as the system design does not include friction loss due to solids loading in the pressure drop calculation. Thus, material loading must be minimal compared to the volume or mass of air flow. [ 654, 2013] Submittal Date: Fri Mar 01 12:08:15 EST 2013 Annex material for FR-21-NFPA 91-2013.
Page 19 of 28 First Revision No. 12-NFPA 91-2013 [ Section No. A.3.3.2 ] A.3.3.2 Air-Moving Device. Air-moving devices include fans, centrifugal fans, or mixed-flow fans. These devices have previously been called blowers or exhausters. Air-moving devices also include steam ejectors and similar devices. An air-moving device is a fan or blower. A general description of each follows: (1) Fans: (a) (b) (c) (d) A wide range of devices that utilize an impeller, contained within a housing, that when rotated create air/gas flow by negative (vacuum) or positive differential pressure. These devices are commonly used to create comparatively high air/gas volume flows at relatively low differential pressures. These devices are typically used with ventilation and/or dust collection systems. Examples are centrifugal fans, industrial fans, mixed or axial flow fans, and inline fans. (2) Blowers: (a) (b) (c) (d) A wide range of devices that utilize various-shaped rotating configurations, contained within a housing, that when rotated create air/gas flow by negative (vacuum) or positive differential pressure. These devices are commonly used to create comparatively high differential pressures at comparatively low air/gas flows. The most common uses of these devices are with pneumatic transfer, high-velocity, low volume (HVLV) dust collection, and vacuum cleaning systems. Examples are positive displacement (PD) blowers, screw compressors, multi-stage centrifugal compressors/blowers, and regenerative blowers.

Page 20 of 28 First Revision No. 24-NFPA 91-2013 [ New Section after A.3.3.11 ] A.3.3.14 Pneumatic Conveying Sytem. Pneumatic conveying systems include a wide range of equipment systems utilizing air or other gases to transport solid particles from one point to another. A typical system comprises the following: (1) A device used to meter the material into the conveying air stream (2) Piping, tubing, hose, etc., used to provide the closed pathway from the metering device to the AMS (3) An AMS designed for the separation of comparatively large amounts of material from the conveying air/gas stream (4) An additional metering device (typically a rotary airlock valve or similar device) that might be used to allow discharge of the separated material from the conveying air stream without affecting the differential pressure of the system (5) An AMD designed to produce the necessary pressure differential and air/gas flow in the system (positive or negative) A pneumatic conveying system requires the amount of material conveyed by the system to be considered as a major factor in the system pressure drop calculations. Both positive and negative (i.e., vacuum) differential pressure are used for pneumatic conveying. The decision of which is the best for a specific application should be based on a risk analysis, equipment layout, and other system operational and cost factors. Dense phase conveying can also be considered for the application, especially with more hazardous materials (e.g., low MIE). The inherent design and operational features of this approach can provide significant safety and operational advantages over other types of pneumatic conveying systems.

Page 24 of 28 First Revision No. 18-NFPA 91-2013 [ Section No. A.4.4.7 ] A.4.4.9 Dust collection systems and centralized vacuum cleaning systems handling combustible dusts usually use branched duct networks with multiple pickup points and variable material loading. In contrast, dilute phase and dense phase pneumatic conveying systems are typically linear systems with controlled infeed and consistent material loading. Dust collection systems for combustible dusts represent a significant increase in deflagration risk compared with most pneumatic conveying systems. A properly designed system is critical to minimizing that risk. For guidance on determining air volume and air velocity, refer to Industrial Ventilation A Manual of Recommended Practice, published by the American Conference of Governmental Industrial Hygienists (ACGIH).
