How many guarding/hazard concerns do you see in this single pic?
You see the darndest things out and about! Today while on our stroll to lunch I came acrss this arrangement that caught my eye. I was so glad to see the black valve below the Relief Valve car sealed in the OPEN (CSO) position. But when we step back, we can see a serious design flaw. This is on a brand new installation, less than a month old! Do you see the problem on this natural gas (NG) manifold?
First the Car Seal pic - OUTSTANDING!
Now see if you can find the mistake?
Who sees it?
When we begin a "human factors" analysis, we should do more than ask "Is the equipment labeled?", as human factors rely on the equipment being PROPERLY LABELED. This is a perfect example of something be labeled, but asking for an accident. Even as obvious of a mistake this is and everyone who looks at this picture will just shake their head, this is a classic example of a "human factors" FAILURE. And yes, I have already been asked by more than one manager... "show me in any OSHA standard where this is a violation and I will fix it".
Many thanks to Bob Cornett for the share!
