Terms of use
The boundaries of DustDHA planning information, provider introductions, and provider billing.
Information only
DustDHA does not perform, review, certify, or sign dust hazard analyses. Content, calculators, and snapshots are planning information—not engineering, safety, compliance, or legal advice.
Source authority
Always confirm requirements against the current NFPA standard, applicable OSHA authority, adopted state and local codes, and qualified professional judgment. Source dates are shown because requirements and public guidance can change.
Provider directory
Profiles summarize claims from each provider’s public website. Inclusion, claim verification, ordering, or matching is not an endorsement, certification, ranking, or guarantee of availability or work quality.
Searcher introductions
The searcher never pays DustDHA. Submitting a qualified RFQ authorizes sharing it with up to 3 matched providers. Providers are independent businesses; any engagement is a separate agreement between the searcher and provider.
Provider pricing
A provider’s free period lasts until both 90 days have passed from its first delivered qualified RFQ and 10 qualified RFQs have been delivered. After accepted terms and billing activation, each receiving provider pays $200 for a score of 60–74, $350 for 75–89, or $500 for 90–100; may buy 5 delivery credits for a one-time $1,750; or uses the $1,000 monthly standard or $1,500 monthly priority retainer. Prices are USD. A shared RFQ may go to no more than 3 providers, and the price applies separately to each receiving provider.
Credits and disputes
A lead credit covers one provider delivery of an RFQ scored at least 60, shared with no more than 3 providers. Credits expire 12 months after purchase. Wrong-fit or unreachable-contact disputes must be opened within 7 days and are founder-reviewed; the usual remedy order is replacement, credit, then refund where appropriate.
Payments
Dodo Payments is the Merchant of Record for provider card payments and may appear on statements or receipts. Dodo handles checkout, payment processing, applicable indirect tax, and payment-method terms. Billing stays disabled until DustDHA has valid product IDs, credentials, webhook verification, and provider terms on file.
Availability and liability
Tools, listings, delivery, and matching may change or be unavailable. To the extent permitted by law, DustDHA is not responsible for decisions made from planning content or for acts, omissions, proposals, or work of independent providers.
