Concept stage · no hardware built yetFounding pilots Spring 2027 (target)
A small node clips onto each plumbed eyewash and records when the valve was opened and how long it stayed open. The person testing it presses a button on the node, and a one-tap email to the lab’s room contacts records who confirmed the visual check. Every Monday, the building’s FlushLog report arrives as a PDF.

Activate the eyewash weekly. Let it run the full time your program sets. Check that the caps are in place, the path is clear and the sign is visible. Initial each week.
Two blank weeks. On paper, nobody sees them until someone reads the sheet, often at the next lab survey.
Initials show that a pen was here. They can’t show when the eyewash was activated, or for how long.
ANSI/ISEA Z358.1 calls for plumbed eyewashes to be activated weekly. On many campuses, someone in the lab activates the eyewash and initials a sheet taped to the wall.
“Record eyewash flushing on the Weekly Eyewash Maintenance Log, usually posted on the wall near the eyewash.”
Duke University Occupational and Environmental Safety Office, lab safety guidance
Flushproof keeps the same record, filled in when the valve is opened: the time, how long it stayed open, and the initials of the person who checked the station.
Public examples of the weekly paper log. Links go to each institution’s own page; none of them is affiliated with Flushproof.
One node per eyewash, one gateway per building, one report per week. Nothing on the station is replumbed.
Shower tests are run by Facilities; a shower can be logged too if a sensor is fitted to it.
This is the sample FlushLog for one fictional building and one week. It’s laid out like the paper log it replaces, so whoever reads it at survey time already knows the columns.

Station log
Each row is one eyewash: when it was activated and how long the valve stayed open, to the second. Both come from the node, not from someone’s memory at the end of the week.
In the sample: 14 stations, 11 activated, and a site target of the valve open for at least 3:00.

Visual check
The node can’t see whether water reached both heads, the caps are on, the path is clear and the sign is visible. A person can. The person testing presses the station button; the confirmation email goes to the lab’s room contacts, and whoever taps it is recorded by initials, the way the paper log does. The record shows who confirmed, not who stood at the station.
In the sample, CS-304 was activated but nobody confirmed the check, so the report says “Not confirmed” and lists it under Needs attention.

Needs attention
A station with no activation shows up in red, by station and room. If it still hasn’t been activated by Thursday, the room contact gets a reminder email; a station that also missed the week before gets a Monday reminder too. The report notes when each was sent.
In the sample, EW-305 in the cold-room vestibule has missed two weeks in a row.

History and records
Page 2 shows the last quarter, one square per station per week: 172 of 182 station-weeks have a recorded activation. Every activation is kept with its station, time, duration and confirmation, exports as CSV, and prints on demand.
Records are kept as long as the site chooses; the default is 3 years.
There is no prototype yet, so nothing below has been measured. Target means a design goal, not a promise. Estimate is arithmetic. TBD means not decided yet.
| Option | Cost | What the record proves | Where it’s strong | Where it falls short |
|---|---|---|---|---|
| Paper log | About $0, plus staff time | Someone initialled a box | Free, familiar, nothing to install or approve | Can be initialled without the eyewash being activated; blank weeks surface late |
| Checklist apps e.g. Mitti (formerly SafetyCulture) | Free plan for up to 10 users; paid plans $24–29 per user per month | Someone tapped “done” at a time and place | Covers every checklist you run, not just eyewashes | Still a walk and a tap at every station; no sensor records the activation |
| Plant monitoring kits e.g. Emerson Rosemount 702 | About $1,700+ per station, plus a gateway | The valve opened, with a timestamp | Proven and shipping for years, built for control rooms | Priced and packaged for process plants and integrators, not lab buildings |
| Flushproof concept | About $89 per station + $249 gateway, then $2 per station per month (est.) | When the valve was opened, how long it stayed open, and who confirmed the visual check | Priced for labs; the weekly PDF follows the paper log’s columns | Concept stage: not built yet |
Sources: Mitti (SafetyCulture) Free and Premium plans, checked Oct 2026; Premium is $24 per seat per month billed yearly, $29 billed monthly. Emerson Rosemount 702 safety-shower monitoring kit, about $1,760 before its WirelessHART gateway, from a 2026 price check (Emerson’s own page doesn’t list a price). Flushproof prices are estimates. Wireless eyewash activation logging for industrial plants has been sold by several companies for well over a decade; Flushproof’s difference is the price and the report, not the sensing.

$2,029est.
A 20-station building is $2,029 up front (est.), under a $3,000 purchasing-card limit if that’s yours. Then $40 a month for reports and the audit archive.
Founding-site pilots are free and run in the Spring 2027 semester. That’s a target: we confirm dates with you first.

What happens next
Burak replies by email to the address you gave. If a pilot fits, you get a one-page pilot letter with the dates, the stations, and how we’ll judge it.
Founding-site pilots are free and target the Spring 2027 semester.
Concept. This page, the sample report and the design exist. No hardware has been built. We’re starting conversations with EHS and lab-safety offices.
One demo node on a real eyewash, before any pilot kits are built.
Free founding-site pilots on loaned evaluation units. Dates confirmed with each site.
A production batch only if the pilots show the record holds up. FCC authorization before any hardware is sold or leased.
Ask them first; we can’t answer for them. No rule we found demands paper. The University of Nevada, Reno’s EHS office puts it plainly: “It is up to each group or department how they would like to handle documentation of their activities.” In a 1992 interpretation letter about bar-code inspection records for safety equipment, OSHA said computer-based records are acceptable if they meet the substantive requirements and hard copies can be produced on request. That letter predates Flushproof and says nothing about it.
No. ANSI/ISEA Z358.1 calls for plumbed eyewashes to be activated weekly; Flushproof keeps the record of that activation. OSHA has not adopted Z358.1, but refers employers to it as guidance. State rules differ: Washington writes weekly activation into law, while California requires it at least monthly.
No. It’s a record of weekly tests. If a station is activated outside a scheduled test, the room contact gets an informational email asking whether it was a real use. Don’t rely on Flushproof to summon help.
The activation is still logged with its time and how long the valve was open. The visual-check column shows “Not confirmed”, and the station is listed under Needs attention, as CS-304 is in the sample report.
The gateway is designed for Wi-Fi or Ethernet; tell us in the form which applies to you. A cellular gateway isn’t designed yet, so we list it as TBD.
That’s the intent. At the estimated prices, a 20-station building is $2,029 up front (est.), under a $3,000 purchasing-card limit if that’s yours, then $40 a month. A PO works too. Nothing can be bought until the hardware has FCC authorization.
As long as your site chooses; the default is 3 years. You can export everything as CSV or print any week at any time, and each Monday’s PDF is yours to file wherever you keep audit records.
I’m Burak Unlu, a computer engineering student at Johns Hopkins in Baltimore. Flushproof is my own project, not a university one. Flushproof starts from the routine that campus safety pages such as Duke’s and Ohio State’s describe: activate the eyewash every week, then record it on a log, usually a sheet posted near the unit. It works, but the sheet can’t show when the eyewash was activated, or for how long.
Nothing is built yet, on purpose. Before I make pilot kits, I want to work with a few EHS and lab-safety teams. If that’s you, the pilot form on this page reaches me directly, or you can email me at flushproof@burakali.com. It’s at flushproof.burakali.com.
