Finding the J-B Weld Steel Reinforced Epoxy sheet is the easy part
Keeping every sheet read, current and ready for an inspector is the work that never ends. HazComFast does it with your crew: the AI extracts each sheet, and every reading leaves a proof.
Extraction: the AI reads every sheet
Scanned, long or in Spanish, it reads
Drop in the J-B Weld Steel Reinforced Epoxy sheet, scanned or not, in English or Spanish. HazComFast reads every page, with progress shown page by page, so a 32-page sheet gets read to the last page.
Every section a foreman needs
Composition, spill response, storage, physical properties, stability and toxicology land on the product page with their source, so the sections a foreman actually needs aren't buried in a PDF.
The AI proposes, a person signs off
Each hazard shows where it came from: extracted from the sheet, or confirmed by a named person on a date. Confidence is measured against the text of the sheet, and below a floor every field is checked by hand before it saves.
A pictogram is never guessed
A pictogram only goes on your label if it's actually on the sheet or follows from its H-codes. H225 on the sheet means GHS02 and DANGER on the label, derived from OSHA's Appendix C.
Checked against 200 real sheets
Every change to the AI is checked against a reference set of 200 real SDSs before it ships. A field it isn't sure about is highlighted for you to check, and the inventory flags products whose extraction hasn't been validated yet.
Proof of reading, without the chasing
Nobody has to remember to ask
Add a hazardous product to a site and every worker there gets one notice with a 7-day due date. A reminder follows at day 3 and an escalation at day 7.
“I read it” can't be a reflex tap
The confirm button stays grey until the worker has scrolled through first aid or to the last page of the PDF and has spent 15 seconds there. The record keeps how long and how far.
A proof of reading the worker keeps
The worker ticks an attestation, and the record keeps which SDS version they read, the server time and the device. They can download their own PDF of it.
A new sheet means a new reading
When a manufacturer updates a sheet and the hazards change, everyone who confirmed the old one is asked to read the new one. Each confirmation keeps which version they read, for which jobsite.
Who read what, in one console
See who hasn't read what, nudge everyone overdue in one click, and export last month's confirmations for one jobsite, each with the SDS version they read.
The reading joins the training file
Each confirmed reading also lands in the worker's training file as a HazCom reading record, so your training records and your SDS records tell the same story.
From the sheet to the label
A label that can't go out empty
A label with five pictograms keeps all five, because the format switches. A label with no hazard information won't print. When the sheet changes, you get a relabeling task with its six-month deadline.
English and Spanish, side by side
Hazard and precautionary statements show in English and Spanish on every product page. A Spanish sheet that says PELIGRO is recorded as DANGER, and the original file stays attached as you received it.
Every print on record
Every print run is logged with exactly what went on the labels. When a hazard changes, the relabel task can only be closed by a print made after the change.
In the field, on the phone
Scan the drum
Scan the QR code on a drum and the page shows the maker and the CAS number under the title, so you know you hold the right one. A drum taken out of inventory still opens its SDS, marked as removed.
Search inside the sheet
Type “eye contact” and you land on first aid. Pinch to zoom on the small print.
Still there with no signal
Offline, the worker opens the sheet itself, with first aid and what to do in a spill. “Available offline” only shows when the PDF is on the phone.
When the inspector asks
The binder, in one click
One click gives you the jobsite's SDS binder, with J-B Weld Steel Reinforced Epoxy in it, as a ZIP with a CSV index, and a dated CSV or PDF of who confirmed reading what. That is what you hand an inspector or a GC.
No expired-sheet myth
HazComFast never tells you a sheet has expired, because OSHA doesn't set an expiration date. You choose your own review interval, and the app labels it as your internal policy.
The chemical list behind it
Bring your spreadsheet
Imported products get the same pictograms as ones entered by hand, and importing the same file twice doesn't duplicate anything.
Each product, at every site
Each product page shows every site it's stored at with quantities, and warns you if something incompatible is stored at the same site.
A program that stays true
The chemical list in your HazCom program is built from each jobsite's inventory. Remove a product and the program tells you the list is out of date, with a button to rebuild it.
Start with the free SDS Binder Kit. It works with nothing but a printer.
Where do I get the SDS for J-B Weld Steel Reinforced Epoxy?
From J-B Weld Company, LLC. The button at the top of this page opens its own copy (many product codes, Revision date Apr 16, 2020). It covers J-B Weld Steel Reinforced Epoxy, Twin Tube: one file with the sheet for Part A (resin) and the sheet for Part B (hardener, slow cure).
Is J-B Weld Steel Reinforced Epoxy a hazardous chemical under OSHA?
Yes: Section 2 lists five hazard classes, among them eye irritation, Category 2A (29 CFR 1910.1200(c)).
