De-energize and have PPE is the way to go home at night, without the free suntan

Is a few hours of after hours overtime that costly?

Should be costly for the customer and $$$ for the owner.

A lot less costly than a blow up and resulting injuries. Never having done this, how long does it take?

It’s very dependent on circumstances. In THIS case it’s a smallish mcc with only loose dust in it. To blow it out would take 20 mins tops including getting the covers off. I’ve cleaned some in the past that took a crew of four all weekend. That was a plant that vulcanized rubber though and the carbon in the gear was thick and sticky.

I’m very pleased that no one has said they would go ahead and do it. I’m glad you are all working safely.

Tim.
I get in arguments about this all the time. It's much more fun blowing things out with compressed air but you have little control where the dust goes. The compressed air generates a lot of force and I am sure it blows dust in areas that it wouldn't normally get.

Ive been in a dust fire at ground zero and it wasn't that bad. The difference between that event and one in a mcc is compression.

In a skirted building (roof and small side walls that do not go to the floor) the flash off rapidly moves away from ground zero and vents rather dramatically outside as it has gained fuel on the way. The most memorable part was how the building went from dusty to clear as a bell in a instant.

Now if you work in feed-mills you will have seen blow out panels because a uncompressed dust ignition is a rapidly moving fire verses a compressed event which is a massive explosion.

In a enclosed mcc i wouldn't take the risk as compressed air may contain water vapor, you also may have drill shavings that are about to be blown around in places that could cause expensive problems and finally the room would cause compression as the door is not large enough to vent that much energy.

We've blown out mcc's before, but always de-energized.

How are you supposed to get the metal air nozzle back in there to blow out around and behind the components and whatnot with all the live terminals?

If someone is just figuring on opening the mcc bucket door and pointing the nozzle straight in from outside the mcc enclosure, that sounds like a fairly half ass way to blow mcc buckets out.

Different strokes, I suppose...
