Safety data sheet
WD-40 Multi-Use Product Aerosol SDS
WD-40 Company's sheet for WD-40 Multi-Use Product Aerosol lists three hazard classes, among them flammable aerosols, Category 1, so it is a hazardous chemical as 29 CFR 1910.1200(c) defines it. The HazCom program, label, sheet and training paragraphs follow ((e)(1), (f)(6), (g)(8) and (h)(1)), unless a scope paragraph of (b) takes the product out.

WD-40 Multi-Use Product Aerosol: facts read in the safety data sheet, by section
Section 2, hazards
Section 2 lists aerosol Category 1, aspiration toxicity Category 1, and specific target organ toxicity single exposure Category 3 (nervous system effects).
Signal word: Danger. Pictograms: Flame (GHS02), Health Hazard (GHS08), Exclamation Mark (GHS07).
Hazard statements: H222, H229, H304, H336. Their text, in English and Spanish, is on the label below.
Section 3, ingredients
LVP aliphatic hydrocarbon (CAS 64742-47-8) at 45 to 50 %, petroleum base oil at under 35 %, aliphatic hydrocarbon (CAS 64742-47-8) at 10 to under 25 %, and carbon dioxide (CAS 124-38-9) at 2 to 3 %.
Section 4, first aid
Eyes: flush thoroughly with water. Remove contact lenses after the first 5 minutes and keep flushing for several more minutes. Get medical attention if irritation persists.
Skin: wash with soap and water. Get medical attention if irritation develops and persists.
Inhaled: if irritation is felt, move to fresh air. Get medical attention if irritation or other symptoms develop and persist.
Swallowed: aspiration hazard, so do not induce vomiting. Call a physician, a poison control center or the WD-40 Safety Hotline at once.
Section 5, fire fighting
Use water fog, dry chemical, carbon dioxide or foam. Do not use a water jet or flooding amounts of water, because the burning product floats and spreads fire.
Containers exposed to extreme heat and flames can rupture, often with violent force. Vapors are heavier than air and can travel along surfaces to an ignition source and flash back.
Firefighters wear positive pressure self-contained breathing apparatus and full protective clothing, and cool fire-exposed containers with water.
Section 7, handling and storage
Store in a cool, well-ventilated area away from incompatible materials, and do not store above 120 °F or in direct sunlight.
Store away from oxidizers; the sheet describes it as a level 3 aerosol under NFPA 30B.
Unplug electrical tools and appliances before spraying, and keep the can away from battery terminals and other sources of electricity.
Section 8, exposure limits
OSHA PEL for petroleum base oil (as oil mist, mineral): 5 mg/m3 (TWA)
OSHA PEL for carbon dioxide: 5000 ppm (TWA)
Section 8, protection
Respiratory protection: For bulk processing or workplace use: none required if ventilation is adequate; if the occupational exposure limits are exceeded, wear a NIOSH approved respirator under OSHA 1910.134.
Safety goggles where eye contact is possible.
Chemical resistant gloves.
The sheet does not name eyewash equipment.
Section 9, flash point
138 °F (59 °C), Tag closed cup
Section 9, other properties
Liquid packaged as an aerosol, light green to amber, with a mild petroleum odor.
Boiling range 361 to 369 °F (183 to 187 °C). Vapor pressure 95 to 115 psi at 70 °F. Insoluble in water.
Flammable limits of the solvent portion 0.6 % and 8 %. VOC 24.1 %. Pour point -63 °C (-81.4 °F).
Section 10, what to avoid
Avoid heat, sparks, flames and other ignition sources, and do not puncture or incinerate containers.
May react with strong oxidizers, generating heat.
Section 14, transport
UN1950, Aerosols, hazard class 2.1. Limited quantity. The maker does not recommend shipping the aerosol by air.
What this product triggers under OSHA
The sheet says the product is a consumer product labeled under the rules of the Consumer Product Safety Commission, which take precedence over OSHA hazard communication labeling. The standard does not apply to a consumer product the employer shows is used as its maker intended, at no more than consumer exposure. (29 CFR 1910.1200(b)(6)(ix), (b)(5)(v))
Section 8 mentions a respirator: the employer provides one when necessary to protect health and keeps a respiratory protection program. (29 CFR 1910.134(a)(2); 1926.103)
Section 8 lists OSHA PELs for petroleum base oil (as oil mist, mineral) and carbon dioxide; the tables are 1910.1000 and, in construction, Table 1 of 1926.55. (29 CFR 1910.1000; 1926.55)
A classified product brings a written program with its chemical list, training, an accessible sheet and workplace labels. (29 CFR 1910.1200(c), (e)(1), (f)(6), (g)(8), (h)(1); 1926.59)

The label carries 5 precautionary statements (P210, P211, P251, P261, P271, P301, P310, P331, P304, P340, P312, P405, P410, P412, P403, P501), and the PDF prints their full text. 8 of its 9 lines have official Spanish; a line marked English only has none that says the same.
Finding the WD-40 Multi-Use Product Aerosol 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 WD-40 Multi-Use Product Aerosol 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 WD-40 Multi-Use Product Aerosol 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.

Where do I get the SDS for WD-40 Multi-Use Product Aerosol?
From WD-40 Company. The button at the top of this page opens its own copy (no product number printed, SDS date of preparation Nov 13, 2024). It covers WD-40 Multi-Use Product Aerosol, the California CARB compliant (low VOC) formula. The bulk liquid and the Specialist products have their own sheets.
Is WD-40 Multi-Use Product Aerosol a hazardous chemical under OSHA?
Yes: Section 2 lists three hazard classes, among them flammable aerosols, Category 1 (29 CFR 1910.1200(c)). Its consumer wording matters (1910.1200(b)(6)(ix)).
