Hello,

I wanted to request insights into the requirements to provide emergency lighting unit in salt / sand sheds (100' x 50') which are classified under National Building Code of Canada major classification "F". These are low-hazard storage facilities which has a overhead door operator and manual door for entry/exit.

The NBCC mentions requirement to provide emergency lighting in "Principal routes providing access to exit in open floor areas". It does not specify applicable building classification types. I assume the manual door for entry/exit may classify as principal route providing access to exit, but I'm not sure if this mandates installation of an emergency lighting unit. So I thought to inquire if anyone familiar with installation of electrical distribution in salt / sand shed type facilities, would provide some insight into this requirement.

Thank you.

We have wired a few salt/sand sheds.
Specifications ( government) called for standard weatherproof fixtures and Teck cable.
None of the sheds had man doors so there was no Exit requirements

Anything metal will get eaten up in there I suspect. if required to put in an exit sign, I would just find a plastic wall pack and install it above the door. There are no designated routes for exit because the sand / salt pile will change daily as it changes in size.

I have been in a few of these over the years, never wired one. Never have noticed any exit sign or emergency lighting in them either.

Cheers
John

Have wired about 10 of the new ones in ontario. Both the wooden style as well as the metal/tarp style.
We usually wire to a set of drawings, there havent been exits or emergency lights on any of the ones that I have done.

Door ops, a few plugs, highbays, fans for ventilation on a timer.
The odd one has brine pumps or CO detection connection.

Always done in PVC, expansions every 40'. Nema 4x Panels.

FYI, NBC is free and available online:

2020 National Building Code - FREE

The references are 3.2.7.3 / 9.9.12.3 for emergency lights, and 3.4.5.1 / 9.9.11.3 for exit signage.

In summary, emergency lights are required in every building except within individual dwelling units / houses / secondary suites. Exit signage is required in buildings that are more than 2 storeys, or have an occupancy load more than 150 people.

On a side note, most of our clients install exit signage even when the building code doesn't require it. It just looks too strange without exit signs.
