Machine Parts Color Coding: How Do You Ensure Safety with the Right Colors?

Seeking Information on Machine Parts Color Coding

Wishing you all a very happy, prosperous, and safe Navratri and Vijayadashami. I am seeking information on the color coding of machine parts and the guards utilized for protection against machine hazards. Please share your knowledge on this subject.

Regards,
Raman

Thank you for the wishes. I reciprocate the same to you and your family. I am not very familiar with the standard color coding for machine parts; therefore, I will refrain from commenting on that. Let's wait for other expert members to provide their input.

Machine Guarding

Now, regarding the machine guarding, please refer to the attachment which mentions the various types of machine guarding. If you require more information on machine guarding specifically, please let me know, and I will be happy to share my knowledge.

Thank you.

Regards

Dear Mr. Raman,

There are no specific standards regarding the color coding of machine parts. However, you can refer to the type of guards (as attached by Mr. Dipil) that are necessary to prevent direct contact with moving parts. You may choose to assign colors to the guards based on different hazards.

Regards.

Dear Raman, The standard states, "Yellow is used to identify physical hazards." If the guard of a machine does not present a physical hazard, such as tripping, falling, being struck by, or caught between, then there is no need for color-coding.

However, when necessary, it is recommended to have the interior of a machine guard painted orange to indicate that the guard is kept open.
