HazComFast vs KHA Online SDS: Construction Compliance Comparison 2026

HazComFast is the construction-first choice; KHA Online SDS (now part of VelocityEHS) is a general-industry SDS database. The single most important difference is access: HazComFast is built for jobsites where the signal drops: the jobsite's SDS load onto the crew's phones before the signal goes, while KHA is cloud-only and goes dark when a jobsite loses connectivity. OSHA requires SDSs to be "readily accessible during each work shift" under 29 CFR 1910.1200(g)(8), adopted for construction by 29 CFR 1926.59, so for crews in basements, tunnels, and concrete structures, the offline gap is usually the deciding factor — not database size.

KHA Online SDS has been a long-standing name in SDS management and now sits inside the VelocityEHS enterprise suite. The question this article settles is narrow and practical: for a construction company governed by 29 CFR 1926.59, is a cloud, general-industry SDS database the right tool — or do you need something built for field conditions and the HCS 2024 deadlines? See also our broader HazComFast vs VelocityEHS comparison and the full alternatives matrix.

At a glance: KHA Online SDS (VelocityEHS) = a large, cloud, general-industry SDS database. HazComFast = construction-first and built for jobsites where the signal drops: each jobsite's SDS load onto the crew's phones, with GHS labels, training records and the HCS 2024 relabel/retrain workflow. On a low-signal jobsite the deciding factor is offline access, not database size. KHA Online SDS, now part of VelocityEHS, is a cloud-based general-industry SDS database with no offline access, while HazComFast is a construction HazCom platform that loads each jobsite's SDS onto the crew's phones before the signal drops, which is usually the deciding factor for crews on low-signal jobsites under 29 CFR 1926.59.

At a glance: the head-to-head table

The rest of this article works through the decisions that actually move the needle — access, database relevance, labels, inspections, training, price, and the looming HCS 2024 deadlines — and ends with who should pick which.

The offline problem (the real deal-breaker)

This is where most construction teams make the decision. KHA Online SDS / VelocityEHS is built around a cloud database — when your crew loses cell signal, they cannot reliably pull an SDS. And signal loss is the rule, not the exception, in: poured-concrete basements, parking structures, tunnels and shafts, steel high-rise cores, rural and remote sites, and anywhere a Faraday-cage effect kicks in.

OSHA does not grade on connectivity. Safety data sheets must be "readily accessible during each work shift to employees when they are in their work area(s)" — that is the literal text of 29 CFR 1910.1200(g)(8), adopted for construction by 29 CFR 1926.59. A cloud-only system on a no-signal site is a "readily accessible" violation waiting to be written.

HazComFast was built for jobsites where the signal drops: your jobsite's SDS load onto the phone on their own, and the app shows how many are ready (17 of 20, 20 of 20) before you head underground. Near-misses, inspections and permits logged without a signal send themselves the moment you're back online. For the full argument, see why cloud-only SDS apps fail on construction sites and offline SDS access: why it matters.

Winner: HazComFast — the only option that stays compliant when the bars disappear.

SDS database size vs. jobsite relevance

KHA's pitch is scale: access to a multi-million-record manufacturer SDS library. That genuinely matters if you are a chemical plant or a multi-industry distributor handling thousands of exotic substances. But a typical construction crew uses 20–200 chemicals — adhesives, sealants, fuels, form-release oils, solvents, concrete admixtures, coatings. A search bar with millions of sheets in it produces noise, not value, and it makes it harder to prove your actual inventory is complete.

HazComFast inverts the model: you build a curated, jobsite-specific inventory, and every chemical is linked to its SDS, its GHS labels, training records, and compatibility checks. The free SDS Gap Analyzer then scores the program around it in 12 questions, and the gap-analysis method is how you confirm no container is missing a sheet 29 CFR 1926.59 requires.

Winner: depends on you. KHA if you need a deep, cross-industry SDS catalog; HazComFast if you want a jobsite-accurate, defensible, actionable library.

GHS label compliance (HazComFast includes it; KHA doesn't)

Labels are half of HazCom, and they are one of OSHA's most-cited gaps. Under 29 CFR 1910.1200(f) (construction via 1926.59), shipped containers need the full label, and workplace/secondary containers under 1910.1200(f)(6) need at minimum the product identifier plus words/pictures/symbols conveying the hazards. The current rule aligns with GHS Revision 7 and requires the eight OSHA pictograms (the ninth, environmental GHS09, is voluntary — see 8 OSHA pictograms vs 9 GHS pictograms).

HazComFast bundles a GHS label generator and a secondary container label maker that output compliant, red-diamond-framed, bilingual EN/ES labels directly from your inventory. KHA Online SDS does not generate labels — you would need a separate tool or manual artwork, which adds cost and reintroduces the exact error OSHA writes up. See secondary container labels: OSHA rules and the common secondary container labeling citation fix.

Winner: HazComFast — labeling lives in the same platform as the SDSs.

OSHA inspection response

When an inspector arrives, "give me a minute to call IT" is not a strategy. HazComFast auto-assembles an inspection / citation response package that includes:

• SDS access logs that demonstrate "readily accessible" compliance (1910.1200(g)(8), adopted for construction by 1926.59)
• Training records with timestamps, signatures, and chemical linkage
• The current chemical inventory with GHS classification data
• Label compliance evidence for shipped and secondary containers

KHA can provide SDS access records, but it does not assemble a construction-ready citation-defense package on demand.

Why this matters in dollars: Hazard Communication ranked second on OSHA's FY2025 list of most-cited standards, and a serious citation can reach $16,550 per violation (the 2026 maximum, unchanged from 2025 — there was no inflation increase), while willful or repeated violations reach $165,514 (29 CFR 1903.15(d)). Documentation is the difference between a quick abatement and a stacked penalty.

Winner: HazComFast — purpose-built for the inspection moment.

Training integration

HazComFast ties employee training to specific chemicals and jobsites, so the records map to the hazards your crew actually faces — which is what 29 CFR 1910.1200(h) requires. Generate toolbox talks straight from your inventory and build complete training files with sign-in sheets and competency verification.

KHA/VelocityEHS offers training modules at the enterprise level, but not the tight construction loop of chemical → label → training → defense doc in one self-serve product.

Winner: HazComFast — training is woven into the compliance workflow, not bolted on.

Pricing & getting started

HazComFast publishes transparent pricing: you read the number before you talk to anyone, and the free tools run in the browser with no account at all. KHA/VelocityEHS uses custom enterprise pricing, annual contracts, and an implementation cycle — fine for a corporate EHS department, heavy for a contractor who needs to be compliant this week.

Winner: HazComFast — lower barrier to entry, predictable cost.

Worked example: migrating a 5-crew GC off KHA

Suppose a general contractor with five field crews currently pays for KHA Online SDS but keeps getting dinged because crews in below-grade work can't pull sheets. Here is the switch, step by step:

1. Export the inventory. Pull the chemical list out of KHA/VelocityEHS as a CSV (product names + manufacturers).
2. Bulk-import into HazComFast. The system matches each product to its SDS.
3. Run the SDS Gap Analyzer. It is a 12-question HazCom self-audit that scores where your program is exposed — SDS access, labeling, training, inventory, multi-employer, the GHS Rev 7 transition — and hands back a prioritized fix list. For the container-by-container reconciliation that names the specific products with no sheet, use the gap-analysis method, then request what's missing (the subcontractor RFI writer drafts the demand letter that cites the supplier's 1910.1200 obligation).
4. Generate GHS Rev 7 secondary-container labels for the spray bottles and drums the crews actually decant into — bilingual EN/ES.
5. Load the phones. Each crew's phone now carries its jobsite's SDS, and the app shows how many are ready.
6. Confirm the deadlines. Run the HCS 2024 deadline lookup so the program update + retraining land before the dates below.

End state: a 140-chemical, jobsite-accurate library, loaded onto the crew's phones, with labels and training in one place — typically completed in under an hour of hands-on work, with no implementation project.

The HCS 2024 deadlines you're switching into

Whatever platform you choose, the clock is running on the HCS 2024 (GHS Rev 7) update. These are the in-force dates (a Jan 15, 2026 final rule extended the originals by four months):

The employer-facing work — updated GHS Rev 7 labels, an updated written program, and retraining — is exactly what a construction-focused platform automates. See HCS 2024 deadlines: complete compliance calendar and the November 20, 2026 retraining trigger. For the underlying rule, see the Hazard Communication Standard 1910.1200 overview.

Common mistakes & myths

• Myth: "Bigger SDS database = better compliance." No. OSHA cites you for your chemicals being inaccessible or unlabeled, not for lacking access to millions of others. A curated, complete inventory beats a giant search bar.
• Mistake: trusting cloud access on a jobsite. "We have an app" is not the same as "the SDS opens in the tunnel." Test it where your crew actually works.
• Mistake: separating labels from SDSs. If your SDS tool can't print compliant GHS Rev 7 secondary-container labels, you've split one HazCom obligation across two systems and doubled the failure points.
• Myth: "HazCom is general industry, so 1910.1200 is my cite." For construction, the operative citation is 29 CFR 1926.59, which adopts 1910.1200 by reference. Inspectors write the 1926 cite.
• Mistake: assuming a migration is a project. Moving a typical contractor inventory is a CSV export/import plus a gap check — an afternoon, not a quarter.
• Myth: "We have until 2028." The mixtures employer date is 2028, but the substances employer date — program update and any additional training for newly identified hazards, as necessary — is November 20, 2026.

Note: This is general guidance, not legal advice. OSHA-approved State Plans may impose HazCom requirements at least as effective as the federal standard; verify your state's rules. Competitor capabilities change — confirm current KHA/VelocityEHS features and pricing directly with the vendor.

What to do next

1. Field-test access where your crews actually work (below grade, remote). If the cloud app fails, the offline question is already answered.
2. Export your KHA inventory to CSV so you have a clean migration starting point.
3. Run the SDS Gap Analyzer — the 12-question HazCom self-audit — to score your program before you switch.
4. Generate compliant GHS Rev 7 secondary labels with the label maker, matched to the right container size.
5. Lock the deadlines with the HCS 2024 deadline lookup; schedule retraining ahead of November 20, 2026.
6. Compare the field honestly — see the VelocityEHS comparison and full alternatives, then read the published prices.

Who should choose what?

Choose HazComFast if:

• You're in construction with field crews on variable-connectivity jobsites (1926.59)
• You need your jobsite's SDS on the phone before the crew heads where the signal drops
• You want GHS Rev 7 secondary-container labels generated from the same platform as your SDS library
• You want to start today, self-serve, without a sales cycle
• You want training, labels, and inspection-defense docs in one workflow

Choose KHA Online SDS / VelocityEHS if:

• You're in manufacturing, pharma, or lab environments with reliable connectivity
• You need a very large, cross-industry manufacturer SDS catalog
• You already run VelocityEHS for broad enterprise EHS (ergonomics, ESG, incident management)
• Your team works indoors and connected, and you have a dedicated EHS staff to administer it

The bottom line

KHA Online SDS is a mature, general-industry SDS database now living inside an enterprise EHS suite. It is a strong fit for connected, multi-industry operations with EHS departments. But it was not built for construction: it's cloud-dependent on no-signal sites, it doesn't generate GHS labels, and it doesn't assemble a construction inspection-defense package. For field crews governed by 29 CFR 1926.59 who need offline access, integrated GHS Rev 7 labels, and automated OSHA documentation — and who are staring down the November 20, 2026 employer deadline — HazComFast is the purpose-built choice.
