operations, in case the situation changes in the future. If this space opens into the
workbays, the requirements of NFPA 70 Article 511 apply.
4-5.9.2 Battery shelving is provided under the construction contract, and is typically of
redwood, cedar or fiberglass, along the side of the room opposite the door. The shelves
