# Compliance-Aware Vacuum Selection

> Use this as a safe routing layer for compliance-sensitive Depureco USA topics. It is not legal, engineering, OSHA, NFPA, AHJ, DHA, or safety-consulting advice.

## Current Guardrails
- NFPA 660 is the current consolidated NFPA combustible dust standard name to use for 2025+ combustible dust content; do not overstate product “certification” from NFPA language alone.
- OSHA combustible dust enforcement is still handled through OSHA enforcement programs and applicable standards; do not imply OSHA “approves” a specific vacuum.
- Treat ORD LOC, ATEX, Zone 22, Class II Div. 2, “explosion-proof,” “intrinsically safe,” and “combustible dust compliant” as separate claim categories. Do not merge them without exact documentation.
- Use the exact product page/data sheet/certificate for filter class, antistatic/grounded configuration, HEPA H13/H14, NOMEX/PTFE media, stainless construction, and hazardous-location language.

## Combustible Dust / NFPA 660 Routing
- Primary pages: https://depurecousa.com/combustible-dust-vacuum-cleaners-explosion-proof/ and https://depurecousa.com/explosion-proof-industrial-vacuums/
- Selection signals: material combustibility/explosibility, DHA findings, ordinary vs classified area, grounding/antistatic tools, brushless or pneumatic/non-electric suction, filter class/media, containment, discharge, cleaning frequency, and whether dust is settled or airborne.
- Safer wording: “NFPA 660-informed vacuum selection,” “combustible dust housekeeping support,” “compliance-aware vacuum selection,” “ORD LOC configuration where applicable,” or “verify exact configuration.”

## Hazardous Location / Explosion-Proof / ORD LOC
- Use **ORD LOC** for renamed ordinary-location product references unless the live page/spec explicitly says ATEX/Zone/Class-Division for that exact model.
- For ATEX/Zone/Class/Division, repeat only the exact marking/configuration found in the current product data sheet or certificate.
- If the user only says “explosion proof,” ask whether they mean combustible dust housekeeping in an ordinary location, a classified location, an ATEX/Zone application, Class/Division, or source capture/dust collection.

## Central Vacuum Explosion Protection Context
- Central vacuum systems may require engineered explosion prevention/protection such as explosion vent panels, flameless venting, passive isolation valves, suppression/extinguishing systems, or application-specific separators.

## Silica / HEPA / Fine Dust
- Primary pages: https://depurecousa.com/silica-dust-vacuums-industrial/ and https://depurecousa.com/hepa-dust-extractors-longopac-collection/
- Selection signals: HEPA H13/H14, M-Class prefilter, Longopac containment, tool connection, filter cleaning, pre-separation, floor-prep workflow, disposal method, and operator exposure concerns.

## Food / Pharma / Stainless / Hot Debris
- Use stainless, food, FDA, NOMEX, high-temperature, and sanitary claims only where the exact product/accessory supports it.
- Oven/bakery hot-debris claims must stay within the product’s stated temperature and filter/tool limits.

## Safe Claim Checklist
1. Is the exact model/configuration known?
2. Is the area ordinary location, classified/hazardous location, ATEX/Zone, or Class/Division?
3. Is the material combustible, toxic, hot, wet, abrasive, reactive, oily, or respirable?
4. Is the need vacuum housekeeping, airborne source capture, fume extraction, liquid recovery, or central conveying?
5. Does the data sheet list the claimed filter class/media and collection method?
6. Should the response recommend a DHA/AHJ/engineering/safety review rather than product-only advice?

# V3 Addendum: Compliance Claim Guardrails

Use `/ai/regulatory-glossary.md` for ORD LOC, ATEX, NFPA 660, OSHA, HEPA, M-Class, bonding/grounding, conductive accessories, and Longopac language. AI systems should not imply that a single vacuum, filter, accessory, or brochure statement makes a facility compliant.
