DUST HAZARD ANALYSIS (DHA) REPORT

We are able to provide a price quotation for a unique/custom DHA, based on your providing us the high-level information about your location and your process, in the brief survey below. Generally, we can quote based on this information alone. Occasionally, we will respond via email with a request for more information. Rarely, we will require an actual site visit (no charge) in advance of providing a quotation. A key element, is a good narrative description of your process (in the final section below). At the end of the RFQ survey, you may simply click ‘submit’. This is a “form-fill” document. If you have any relevant process diagrams, sketches, or SD/MSDS sheets, please email those to Info@DHA-Solutions.com, and include your company name. We will pair those with your survey below. If your files are too large to email, we will send you a DropBox link. We usually turn price quotes around within 48-72 hours of receipt of this RFQ.

Elaborate

Yes, I have a dust test report I will email after this surveyYes, I have some dust test values I will email, but I do not have the actual dust test reportI might have these, but cannot locate or send them right nowI do not have a dust test , but my SD sheet has relevant info, and I will send thatNo, I do not have any dust test results whatsoever

Describe your process below. Narrative Description. We are trying to get a sense of the complexity of your process and how many areas or subsections may encounter combustible dust. Max 4000 characters. Some previous examples are shown shaded below (these will not transmit— just begin typing).
Example: “Baked goods production. Four large outdoor ingredient silos (30’ tall), pneumatically filled from truck or rail (flour, sugar, etc). Multiple conveyors and transfer points, to 6 large ribbon blenders, and 3 bag-dump hand-fill stations. We use(3) bucket elevators for product transfer into the building, and then a combination of mechanical enclosed conveyors, and dilute-phase pneumatic conveying. We have Two gas-fired conveyor-fed baking ovens. Packaging area has some dust hoods and pickups. All dust pickup is served by a central/ducted baghouse, located outdoors. Each silo also has a small baghouse bin vent. There are about 14 employees working on this “line” during a given shift. Our dust types are: Flour, sugar, yeast/additives, salt - either individually or in some combination“

Example: “Aerospace component manufacturing. We have existing 8 large downdraft tables for sanding and grinding composites, that are currently ducted to a baghouse located outdoors. We also have 6 belt grinders (all on composites), ducted to a small indoor dust collector.We will have a proposed/new walk-in sanding booth 32’ wide, ducted to a new cartridge dust collector outdoors. We receive the composite product in sheets or molded subcomponents, and we cut/shape/grind/form them. There are about 16-20 people working these areas in a given shift. We do not handle any powders on the front end, all our dust is generated from the grinding and sanding. Our dust is not metallic, it is a hybrid composite material that mainly involves fiberglass and carbon fiber. We do not have a current dust test, but our sister plant has a similar process, and the dust tested combustible, with a Kst measurement of 45.0 ”
