Safety data sheets by product

Battery acid SDS

Battery acid (also searched as battery electrolyte, sulfuric acid battery, lead acid battery acid) has no single safety data sheet. Each maker writes its own, and Section 2 of the sheet you hold decides what it sets off under OSHA. The employer keeps it readily accessible each shift (29 CFR 1910.1200(g)(8)). 4 official sheets are linked below.

Why does the battery acid SDS change with the brand?

The acid and the battery have separate sheets. Interstate Batteries' Battery Electrolyte / Battery Acid sheet lists skin corrosion Category 1A, serious eye damage Category 1 and carcinogenicity Category 1A. EnerSys's Battery Electrolyte sheet lists carcinogenicity Category 1A for mist and skin corrosion Category 1A. A wet battery has its own sheet, written for the battery as a whole; Interstate's and East Penn's sheets for batteries filled with acid are examples.

The sheets below carry dates from Dec 11, 2017.

The electrolyte is dilute sulfuric acid, which has its own chemical page: Sulfuric Acid (CAS 7664-93-9).

What should I read first on my sheet?

Decide whether you hold the electrolyte or the battery. Interstate's electrolyte sheet lists skin corrosion Category 1A, serious eye damage and carcinogenicity Category 1A, and EnerSys lists carcinogenicity Category 1A for mist and skin corrosion Category 1A. A corrosion class brings drenching and flushing where eyes or body may be exposed. The battery filled with acid has its own sheet, written for the battery as a whole.

What does your sheet set off under OSHA?

Paragraphs a battery acid sheet can set off
If your sheet says	What follows	Paragraphs
Section 2 lists any classification	Written program with chemical list, training, sheet access, labels.	(29 CFR 1910.1200(c), (e)(1), (f)(6), (g)(8), (h)(1); 1926.59)
Section 2 lists skin corrosion or serious eye damage	Drenching and flushing.	(29 CFR 1910.151(c); 1926.50(g))
Section 8 calls for a respirator	Respiratory protection program.	(29 CFR 1910.134(a)(2); 1926.103)
Section 8 lists an OSHA exposure limit	The 1910.1000 tables, and Table 1 of 1926.55 in construction.	(29 CFR 1910.1000; 1926.55)

Finding the battery acid 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 battery acid 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 battery acid 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.

Questions about battery acid

Does charging a lead-acid battery change which paragraph applies?

The sheets read here list corrosive classes, so the paragraph on drenching and flushing applies where eyes or body may be exposed (29 CFR 1910.151(c)). Charging rules sit in other standards that this page does not cover.

Do I use the electrolyte sheet or the battery sheet?

Both, if you keep both products. The electrolyte sheet covers the liquid sold for filling. The battery sheet covers the battery as it ships.
