E-Stop

[drewj]

Good morning,

I work for a custom equipment builder and we have had a few customers request that e-stop buttons have a yellow background. Is that an industry safety standard that along with the button being red, palm or mushroom shaped, and unguarded; that it also have a yellow background? Thanks for the help.

Re: E-Stop

NFPA79

10.7.4 Emergency Stop Actuators. Actuators of emergency stop devices shall be colored RED. The background immediately around pushbuttons and disconnect switch actuators used as emergency stop devices shall be colored YELLOW. The actuator of a pushbutton-operated device shall be of the palm or mushroom-head type. The RED/YELLOW color combination shall be reserved exclusively for emergency stop applications.
Exception: The RED/YELLOW color combination shall be permitted for emergency stop actuators in accordance with 10.8.4.

Hopefully if you are a machine builder you would have and already comply with this requirement.
