Height Requirement for a mechanical push button e-stop

hazard22 · Dec 21, 2001

Holiday greetings to all.

I'm looking for a confirmation source for the height required of manual push button e-stops. They are being used on a electro/mechanical test bench that runs cal fluid [ Mil 7024 ] as the test medium. I believe it comes from NFPA or ANSI however I am having no luck digging it out.

Somewhere between 88 and 108 cm.
Check out some good books about ergonomics, drafting, or architecture. Steven van Els

Have you checked NFPA 79?

Contact your company insurance rep., they should be able to produce the applicable documentation per code.

NFPA 79 Sec.13.7 will explain location of E-stops.

conduit · Mar 10, 2003

Information on emergency stop location can be found in
OSHA and the Electrical codes. An e-stop has to be accessible to any operator working on the machine.There is a minimum distance specified in one of the above sources. Height is important as far as making it easy to reach. An operator has a reach diameter of 37 inches. Take that into consideration.
