Default Emergency circuit marking

How do you guys typically identify exposed conduits, boxes and cable for emergency circuits where it’s back up by a generator?
The code says it needs to be permanently marked at intervals not exceeding 25’.
Do you need to use working.
On the rough in I spray painted the inside of 1900 boxes so apprentices would not get confused.
Above drop ceilings I also squirted paint on conduit to keep confusion down

our factory marked the conduit for emergency circuits and fire alarm circuits with a red stripe and the j boxes were painted red entirely.
but you might find it different in many places

Some jobs I've been on they spec'ed the EM ckts be in orange conduit. You can order it colored, but, I don't know the minimum amount or lead time.

Around here I mostly see the entire conduit and boxes painted red. McMaster stocks conduit in different colors but they are not the cheapest. I see a lot of guys for small jobs just paint it with a brush (looks ok).

The last two jobs I was on fire alarm was red. The life safety branch was orange. The critical care branch was yellow, and the emergency equipment branch was green. I don't think there was a big difference in price. At least not when your buying close to 40,000 feet of 3/4".

There's a minimum order to run some colors. The job specs called for marking every ten feet. It was cheaper to buy it colored than to throw a wrap of tape on it. It looks nicer and cheaper than spay bombing it in sections before it goes up.

We also had white for security and blue for phone and data. I whisk I took some pictures of the thousands of feet of blue 1" with a 90 bent on the end for data drops. They had an apprentice bending it for weeks with the greenlee 555 shot gun shoe.

They bought boxes pre painted also.

Can you get away with just painting the couplings?

The facilities here have a panel gear coding.
Including the substation feed, panel floor, 208 or 480, etc.
Part of the coding is if it's one of the 3 standby / emergency / life safety systems.
So most J-boxes, and all the gear is labeled. That's as far as we go.
Exception is I seen all the colored conduit in hospitals.

Well I don't have any of my " KAPU - FIRE ALARM " STICKER PLAQUE'S handy but here is one of my " KAPU- SECURITY SYSTEM" ones that are pretty much the same thing. I put them in panels where I ran a circuit for FA next to the breaker.

When you come to Hawaii and you look in a commercial panel and find one, you get to say " hot damn, I'm hot on the trail of macmikeman now by golly".

Useally I order color coated conduits and boxes if possible.

there are some boxes I will either paint it or send it to the paint shop and they can paint boxes ( if you have large numbers of them to be painted then it may be a wise move on that)

The excat color code will varies a little but genreally fire alarm circuits typically in Red conduits and some emergecy source circuits will be on red conduits too but again all it depending on how the building layout and how they will use that.

But just beaware of lead time if you going to order color coded conduits. but red is pretty common one so you can get it pretty quick., but others colors that will varies.

We can buy colored EMT off the shelf here.
I recently bought some white 3/4" to run exposed on a white wall so I didn't have to go back and paint it.
Also, we hung some LED fixtures from some black EMT to match the ceiling.
If we paid a premium for it, it wasn't that much at all.
BTW, the brand we bought wasn't powder crossed and very much noticed the paint gets scratched off pretty easy if it's thrown around or over handled.
