Quick facts
- An eye wash solution is a sterile aqueous solution for washing, bathing or flushing the eye. The United States writes that definition into its over-the-counter drug rules at 21 CFR 349.3.
- United States: 21 CFR 349.20 sets the permitted active ingredient of an eyewash — purified water — and requires tonicity agents, pH adjustment and a preservative. 21 CFR 349.78 fixes the words that may appear on the label.
- Canada regulates the same bottle through the Medical Devices Regulations, SOR/98-282 and, where a workplace obligation applies, through provincial occupational health rules rather than a federal eyewash monograph.
- Ontario names the fluid itself as equipment: R.R.O. 1990, Reg. 851, s. 124(1) requires "antidotes, flushing fluids or washes" where a worker may be exposed to a hazardous biological or chemical agent.
- There is no Canadian standard for the hardware. The Canadian Centre for Occupational Health and Safety states that the ANSI Z358.1 equipment standard is generally used as a guide in Canada.
- Flow and duration are performance values, not preferences: 1.5 litres per minute to both eyes for 15 minutes for an eyewash station, and 11.4 litres per minute for a combined eye and face wash.
An eye wash solution is one of the least expensive items in a first-aid cupboard and one of the few expected to be used within seconds of an accident. That combination — low cost, high consequence — is why the detail matters: the United States writes the fluid into a named drug monograph, Ontario writes it into a workplace duty, and neither country publishes a national hardware standard a Canadian buyer can quote.
This article sets out what the product is, how each country files it, why the hardware question is answered by a United States standard on both sides of the border, and what a workplace programme documents ahead of the consumables list.
What counts as an eye wash solution?
The United States publishes the definition, and it is narrow in three useful ways.
The product must be sterile. The regulation describing an ophthalmic drug product states that the product "should be sterile in accordance with 21 CFR 200.50", and the eyewash definition itself begins with the word sterile.
The product is defined by its job, not its container: 21 CFR 349.3 reads, "Eyewash, eye lotion, irrigating solution. A sterile aqueous solution intended for washing, bathing, or flushing the eye."
The formula is also prescribed. 21 CFR 349.20 states: "The active ingredient of the product is purified water. The product also contains suitable tonicity agents to establish isotonicity with tears, suitable agents for establishing pH and buffering to achieve the same pH as tears, and a suitable preservative agent."
- A bottle of saline is not automatically an eye wash. Isotonicity with tears and tear-matched pH are written into the monograph because an irrigating solution that stings is a solution a worker will not use for fifteen minutes.
- The preservative is part of the specification. A preserved solution has a shelf life after opening; a preservative-free vial has a different storage story.
How does the United States regulate an eyewash?
The United States places eyewashes inside the over-the-counter drug system, which means a compliant product does not need a new drug application to reach the shelf. That route comes with prescribed labelling.
21 CFR 349.78 requires the label to identify the product using one of a closed set of terms — "eyewash", "eye irrigation" or "eye irrigating solution" — and to place the indication under the heading "Indications", using one of the permitted phrases. The permitted indications are built from a verb list (flushing, irrigating, cleansing, washing, bathing) and a target list (loose foreign material, air pollutants such as smog or pollen, chlorinated water), plus relief wording for irritation, discomfort, burning, stinging, smarting or itching. The regulation also requires a warning that directs the user to consult a doctor if pain, vision changes or persistent redness occur or worsen.
A second layer sits under the drug rule. 29 CFR 1910.151(c) requires that "where the eyes or body of any person may be exposed to injurious corrosive materials, suitable facilities for quick drenching or flushing of the eyes and body shall be provided within the work area for immediate emergency use". The fluid is therefore regulated as a drug, and its availability is regulated as a workplace condition.
Does Canada regulate eye wash solution the same way?
No. Canada does not publish a federal eyewash monograph of the kind described above, and the workplace obligation is provincial.
Two routes matter in practice.
The product route. An aqueous solution sold to flush the eye is assessed against the Medical Devices Regulations, SOR/98-282 and its Schedule 1 classification rules where it makes a device claim, and against the drug provisions where it makes a therapeutic claim. Importers and distributors of the device side hold an establishment licence; the Health Canada medical device guidance index is the entry point for current documents.
The workplace route. Ontario states the obligation directly. R.R.O. 1990, Reg. 851, s. 124(1) provides that where a worker is required to work with, or is likely to be exposed to, a hazardous biological or chemical agent that could cause injury to the eye or skin, the employer shall provide as many of the following as are needed for adequate emergency treatment: eye wash facilities; emergency showers; and antidotes, flushing fluids or washes. Subsection (2) adds four conditions — clear marking with a sign or label, location in a conspicuous place near where the agent is kept or used, ready accessibility to workers, and instructions for use displayed on or near the equipment. That subsection carries the citation O. Reg. 186/19, s. 7, which is the amendment that produced the current wording.
The wording matters to a buyer because it names the fluid and the facility in the same subsection. A practice that stocks solution but has no marked, accessible station has satisfied half of one requirement.

CliniEco Medical holds Health Canada MDEL #35334 as an establishment, which is an authorisation to import and distribute devices in Canada. It is not a statement about any individual bottle of solution.
Why is there no Canadian standard for the station itself?
Because the bodies that would write one have not, and the practical effect is that a United States standard travels north.
The Canadian Centre for Occupational Health and Safety states the position plainly: "Currently, there is no Canadian standard for the design or placement of eyewash stations or emergency showers. As a result, the American National Standards Institute (ANSI) Standard Z358.1-2014 (R2020) 'Emergency Eyewash and Shower Equipment' is generally used as a guide."
The same page supplies the performance values that most Canadian specifications end up quoting, and they are worth writing into a purchase document verbatim:
- An eyewash station should deliver fluid to both eyes simultaneously at not less than 1.5 litres per minute (0.4 gallons per minute) for 15 minutes.
- A combination eye and face wash station requires 11.4 litres per minute (3.0 gallons per minute), and in either case the flow should not be at a velocity that may injure the eye.
- The unit should be mounted so the nozzles sit between 83.8 and 134.6 cm (33 to 53 inches) from the floor.
- ANSI Z358.1-2014 (R2020) itself does not state how long an affected body part must be rinsed; it specifies that equipment installed according to the standard is capable of providing flushing liquid for a minimum of 15 minutes.
That last point is the one that gets misread most often. The fifteen minutes is a capability of the installed equipment, not a clinical instruction; actual flushing time is guided by the safety data sheet.
| Item | Canada | United States |
|---|---|---|
| National equipment standard | None published; ANSI Z358.1 used as a guide | ANSI/ISEA Z358.1 |
| Flushing fluid supply | Capability defined by the standard a buyer chooses to follow | Minimum 15 minutes of flushing liquid under Z358.1 |
| Eyewash flow rate | 1.5 L/min to both eyes for 15 minutes in the specification most often quoted | Not less than 1.5 L/min under Z358.1 |
| Combined eye and face wash | 11.4 L/min where a face wash is also required | Same standard, same order of magnitude |
| Nozzle height | 83.8 to 134.6 cm from the floor | Governed by the same standard |
| Where the legal duty comes from | Provincial regulation, such as Ontario Reg. 851 s. 124 | 29 CFR 1910.151(c) |
What does a workplace eye-flushing programme document?
The equipment is the visible part of a programme that lives in paperwork. Four records carry the weight.
The hazard assessment that triggered the requirement. Ontario phrases the trigger as a hazardous biological or chemical agent that could cause injury to the eye or skin, so the assessment names substances and tasks, not rooms.
The installation record. Marking, conspicuous location near where the agent is used, ready accessibility and displayed instructions are four separate conditions, and each is easy to fail quietly — a station hidden behind a trolley is not readily accessible.
The maintenance log. Weekly activation of plumbed units and replacement of fluid in portable units keeps the fifteen-minute capability true on the day it is needed.
The training record. CCOHS personal protective equipment guidance covers the wider employer duty to assess hazards and select protection, and the eye-flushing station is the emergency end of that duty. AAO patient information on chemical eye injury describes the acute picture a first-aider has to recognise.
Which consumables does an eye-flushing station consume?
- Solution and refills. Preserved solution for plumbed or portable units, and single-use vials where a clean pour is preferred. Ordering cycles become predictable once the number of stations is known.
- Absorbent and dressing material. After flushing, the eye is usually covered while the patient is moved. Sterile gauze sponges and hypoallergenic paper tape are the two items that make that transfer uneventful.
- Gloves and eye protection. Nitrile examination gloves are consumed while helping a casualty, and a face shield protects the person assisting a patient whose eye is still discharging fluid.
- Spill and waste handling. A spill that reaches an eye usually leaves contaminated wipes and waste behind, and biohazard medical waste bags are part of clearing the area.

Frequently Asked Questions
Is sterile saline the same as an eye wash solution?
Not automatically. In the United States 21 CFR 349.20 sets the active ingredient of an eyewash as purified water with tonicity agents, pH and buffering agents to match tears, and a suitable preservative. A saline product that is sterile but not formulated and labelled as an eyewash is a different item; read the indication on the label rather than the word saline.
Does Canada have a federal eyewash monograph?
No. Canada does not publish a federal over-the-counter monograph for eyewash solutions of the kind found in 21 CFR part 349. A product is assessed under the Medical Devices Regulations or the drug provisions according to the claim it makes, while the duty to provide flushing fluid at the workplace comes from provincial regulation, such as Ontario Reg. 851 s. 124(1).
How long should an eye be flushed?
The fifteen-minute figure in ANSI Z358.1 is a capability of the installed equipment: the standard specifies equipment capable of supplying flushing liquid for a minimum of 15 minutes. How long an individual eye is actually rinsed is a first-aid decision, and the safety data sheet for the substance involved is the document that guides it.
What flow rate must an eyewash station deliver?
The specification most Canadian buyers quote comes from the CCOHS summary of ANSI Z358.1: not less than 1.5 litres per minute to both eyes for a combined period of 15 minutes, and 11.4 litres per minute where a combination eye and face wash is required.
Is an eye wash solution a device or a drug in Canada?
It depends on the claim. A solution presented for flushing and washing the eye is assessed under the Medical Devices Regulations and their classification rules, while a product making a therapeutic claim falls under the drug framework. Hold the labelling and the licence information with the purchase record.
What should be documented next to the station?
Four records: the hazard assessment that identified the exposure, the installation record showing marking, location, accessibility and displayed instructions, the activation and fluid-replacement log, and the staff training record. Ontario Reg. 851 s. 124(2) lists the first four as conditions of the equipment itself.
