This picture shows some heavy timber construction in an old shoe factory. These are about 12-15 foot ceilings. You just don’t see this kind of construction any more.
Secondly, you can see the open junction boxes with wires hanging out.
This building is still operating mostly as storage. There is not any production anymore, but there are many combustible foams and plastics that are used in shoe soles and rubber mats.
Although the wires aren’t likely to be touched by anyone as high as they are, they could and probably will short or arc from inadequate installation.
Keep these thing in mind when doing your inspections. Take the time to look at these old buildings and ask about it’s history. These buildings won’t be around much longer, but, boy did they have some charm.
Take care and stay safe.
