Do You Need an SDS for WD-40, Windex and Other Everyday Products?

Short answer: it depends on how your staff use it, not on what it is or where you bought it. The Hazard Communication Standard, 29 CFR 1910.1200, exempts consumer products when they are used in the workplace the same way a household consumer would use them — same sort of task, comparable frequency and duration. Use the same tin more often, for longer, or in a way a householder never would, and the exemption stops applying. That is why the honest answer to “do I need an SDS for WD-40?” is another question: who uses it, how often, and for how long?

Why this rule catches people out

Almost every small employer assumes the exemption attaches to the product — that a can bought from a supermarket is exempt and a drum bought from a distributor is not. It does not work that way. The exemption attaches to the exposure. Identical products, identical packaging, two different workplaces, two different answers.

A tin of lubricant used once a month to free a sticking door is the kind of use a householder would recognise. The same tin, used by a maintenance technician for a large part of their shift, several days a week, is not. The second person has meaningfully more exposure than any consumer, and the exemption was never meant to cover them.

The three questions that settle it

Applied to a specific product and a specific person, in your workplace:

1. Is the task the same kind of thing a consumer does? Wiping a surface, oiling a hinge, yes. Decanting into unlabelled bottles, spraying continuously for an hour, applying it inside an enclosed space, no.
2. Is it used more often than a household would use it? Duration and frequency are the substance of the test, and they are the part people skip.
3. Would a reasonable person call this occupational use? If the honest answer is yes, treat it as covered.

If any answer points to occupational use, the product belongs in your chemical inventory with a safety data sheet available to the people using it, and it belongs in your training.

Where the exemption rarely holds

• Anything decanted into another container. Pouring concentrate into spray bottles or buckets is rarely how a householder uses a product. Once the exemption does not fit, every bottle you fill is a secondary container and secondary container labelling applies.
• Products bought in trade sizes. A drum is not a consumer package, and the use pattern that goes with buying a drum is rarely a consumer one.
• Anything your own risk assessment already flags. If you have controls, PPE or a procedure around a product, you have already decided it is occupational.

The practical answer for most small workplaces

Keeping a safety data sheet for a consumer product you could arguably exempt costs you very little. Arguing the exemption during an inspection, or discovering mid-incident that nobody could find the sheet, costs a great deal more. Most small employers are better served by collecting the sheet and moving on than by building a case for leaving it out.

The exemption is genuinely useful at the margins — the hand soap in the washroom, the air freshener in reception. It is not a reason to leave the maintenance cupboard undocumented.

Where this bites during an inspection

The failure is rarely “you were missing a sheet.” It is that nobody could explain the reasoning. An employer who says “that one is exempt, it is just a household cleaner” and cannot describe how it is actually used has not made a judgement, they have made an assumption. Write the reasoning down once, per product, and the question is answered before it is asked.

Worked examples: Dawn, Windex, Fabuloso and Roundup

What the manufacturers’ own safety data sheets say for four of the most-searched household brands, and how the exemption in 29 CFR 1910.1200(b)(6)(ix) applies to each (sheets checked October 10, 2026):

• Dawn dish soap SDS — classified (eye irritant, combustible liquid), so a restaurant dish station or cleaning crew outside the exemption needs the sheet.
• Windex SDS — Windex Original is not classified at all, so the exemption question barely matters; the never-mix warning still does.
• Fabuloso SDS — household Lavender not classified, but the Professional and 10X Concentrate versions are.
• Lysol SDS — Lysol disinfectants are EPA-registered pesticides too, so the exemption is a poor fit; the spray and All Purpose Cleaner are classified, the wipes are not.
• Roundup SDS — a FIFRA pesticide sits outside the CPSA and FHSA definitions the exemption is built on, so do not rely on it for a weed killer.

Frequently asked questions

Do I need an SDS for WD-40?

If it is used occasionally for the kind of task a householder would do, the consumer product exemption can apply. If maintenance staff use it routinely as part of their work, it should be in your inventory with a sheet. The product is the same; the answer follows the use.

Does buying a product at a supermarket make it exempt from HazCom?

No. Where you bought it has no bearing. The test is how the product is used in your workplace compared with how a consumer would use it.

We decant cleaner into spray bottles — does the consumer product exemption still apply?

Usually not. Decanting concentrate into spray bottles or buckets is rarely the way a householder uses a product, and once the exemption does not apply, each bottle is a secondary container that must be labelled.

Is hand soap covered by HazCom?

Ordinary washroom hand soap used for washing hands is the clearest case for the exemption. An industrial hand cleaner used repeatedly through a shift is a different question.

What if I am not sure whether a product is exempt?

Keep the sheet. The cost of holding one you did not strictly need is close to zero, and it removes the argument entirely.
