Dear SSM,
Mr.hami, Mr.sam, Mr.sachin, Mr.PBR, Mr.dipil given a solution about your query.
OSHA doesn’t require any particular colors for helmet as per our requirement and easy identification only we will use differ colors of hardhats. But OSHA required/suggest using high visibility color hard hats that’s why we are use mostly yellow, red, green, and white.
But I heard EM-385 have some standard colors for hardhats I DONT HAVE ANY PROOF I mentioned that section below if anybody get standard color document please share on this thread its help to our EHS professionals. . . AGAIN I MENTIONED I DON’T HAVE ANY PROOF FOR THIS I HEARD THIS FROM MY FRIENDS WHETHER I GET ANY DOCUMENT WILL SHARE WITH US. . .

Keep on sharing. . .
