        "question": "Do I need an explosion-proof vacuum or a combustible dust housekeeping vacuum?",
        "answer": "Start with the facility’s documented area classification, not the product name. An ordinary-location combustible-dust housekeeping vacuum may be considered only when the pickup area is documented as ordinary location. A hazardous classified location requires equipment suitable or approved for the exact class, division or zone, material group and temperature conditions. Before recommending a vacuum, review the material, SDS and available dust-test data, the dust hazard analysis, ignition sources, pickup volume, collection method and the required hose, tools, filtration and disposal configuration. The same dust can require different equipment in different parts of a facility.",

        "question": "What is the difference between ORD LOC, ATEX, Class I Div 1, Class I Div 2, and Class II dust areas?",
        "answer": "ORD LOC is Depureco’s ordinary-location configuration term; it is not a hazardous-location approval. ATEX is the European equipment and workplace framework for explosive atmospheres and uses zone, group, category and Ex-marking information. In the U.S. Class I addresses flammable gases or vapors, while Class II addresses combustible dust. Division 1 generally describes a hazard expected during normal operation; Division 2 generally describes a hazard expected only under abnormal conditions or where containment normally prevents release. These systems are not interchangeable. Use the facility’s written classification and the exact product marking or certification record.",

        "faq_id": "V10-FAQ-003",
        "question": "Can a vacuum make a facility NFPA 660 compliant?",
        "answer": "No single vacuum makes a facility compliant. A properly selected industrial vacuum can support the housekeeping portion of a combustible-dust program, but compliance depends on the complete facility and process: the dust hazard analysis, material testing, accumulation limits, ignition-source controls, ventilation or dust collection, operating procedures, training, inspection, maintenance, disposal and the authority having jurisdiction. The vacuum must also match the area classification, material behavior, collection method and required accessories. Product language should describe NFPA 660-oriented housekeeping support rather than claim NFPA certification or facility-wide compliance.",

        "faq_id": "V10-FAQ-004",

        "answer": "Provide the exact material and process, SDS, available Kst, Pmax and minimum-ignition-energy data, particle size, bulk density, moisture, temperature and whether the dust is conductive or reactive. Also provide the facility’s dust hazard analysis and area classification, likely ignition sources, pickup volume per shift, hose distance, power or compressed-air availability, filtration target, collection and disposal method, and whether the material must be recovered, contained or inerted. Photos, samples and a description of current cleanup methods help identify the required vacuum, hose, tools, filters, grounding path and discharge configuration.",

      {
        "faq_id": "V10-FAQ-005",
        "question": "Should combustible dust be collected with a portable vacuum, dust collector, or central vacuum system?",
        "answer": "Use a portable industrial vacuum for settled material, machine cleanup, spills and mobile maintenance tasks. Use a dust collector or source-capture system when the main problem is airborne dust generated continuously at a process. Use a central vacuum system when multiple pickup points, long runs or routine plant-wide housekeeping justify a fixed network and centralized collection. Many facilities need more than one approach: source capture for airborne generation and a properly selected vacuum system for settled dust. The material, production rate, area classification, duty cycle, disposal method and facility layout determine the correct combination.",

        "faq_id": "V10-FAQ-006",
        "question": "What features matter for hazardous or combustible dust collection?",
        "answer": "The required features depend on the material and location. Important considerations can include the exact hazardous-location marking where the area is classified, a verified conductive path through the tool, hose, couplings and vacuum, grounding instructions, antistatic filter media, an appropriate primary filter and optional HEPA stage, safe filter cleaning, controlled collection and disposal, and stainless or inertization configurations when engineering determines they are necessary. No single feature proves suitability: grounding, an antistatic filter or HEPA filtration does not independently make a vacuum explosion-proof, ATEX, Class II Division 2 or NFPA compliant.",

        "question": "Can an industrial vacuum collect flour, grain dust, aluminum dust, or other combustible powders?",
        "answer": "Potentially, but only after the exact material, process and location are reviewed. Flour and grain dusts can be combustible; fine metal powders can also be conductive, reactive or capable of generating hydrogen under certain conditions. The recommendation changes with particle size, moisture, temperature, ignition sensitivity, area classification, pickup volume, filtration, grounding, collection and disposal method. Do not use a blanket material list as approval. Provide the SDS and available dust-test data, and involve qualified EHS or engineering personnel when the material is combustible, reactive or handled in a classified area.",
