How far to the eyewash?
ANSI/ISEA Z358.1-style guidance commonly expects emergency eyewash/shower access within about 10 seconds of travel (often taught as ~55 ft / 16.8 m on a clear path). This tool converts distance and walking speed into time.

Formula: Time = Distance ÷ Walking speed · Compare to 10 s / 55 ft guidance
Frequently asked questions
Is 55 ft mandatory everywhere?
It is a common planning figure — follow the edition of Z358.1 or local code you adopt.
Obstructed paths?
Doors, stairs, and locked areas invalidate the distance — path must be immediate and unobstructed.
Strong acids?
Highly corrosive materials may need closer units — risk-assess.
Tepid water?
Temperature and flow requirements are separate from travel distance.
