A mezzanine platform instantly offers abundant new space in the warehouse: Here's what to consider before installing
When considering a mezzanine platform for a distribution facility, a few key questions have to be addressed — management needs to know about stairs, railings, gates, and other equipment needed to make the new structure safe.
Cogan Wire, a Canadian manufacturer of mezzanine and industrial safety systems, frames mezzanine safety around four questions.
- How do workers get on and off the mezzanine?
- How are the edges protected?
- What about transferring materials on and off the platform?
- And are the components being specified as a complete system?
How do workers get on and off the mezzanine?
Most building codes and fire regulations require more than one means of egress for a second story structure. Cogan’s four staircase models are designed to meet IBC and NBCC standards, and use galvanized anti-slip stair treads. All have a maximum rise of 12 feet. Staircases over this height require a mid-landing by code, and these are sold separately by Cogan.
Wherever floor space is a concern, the 24-inch wide platform ladders are a good option, with an optional welded safety cage. It’s up to the local building inspector to decide whether a ladder can be considered an acceptable means of egress.
What type of railing is needed?
Cogan offers 2-rail, 3-rail and wire mesh handrails in standard 42 inch height. It positions the 2-rail for light-duty protection, while the wire mesh is its upgraded handrail for mezzanines intended for public use. Self-closing safety gates close off stairways and ladder landings.
What about the transfer point?
The opening at the mezzanine edge where materials are transferred on and off the structure is one of its most exposed points. The right gate depends on the width of the opening and the direction of flow. Cogan’s standard opening sizes range from 30-inch to 4 feet for single swing gates, 5-feet to 8-feet for double swing gates and 5-feet to 12-feet for sliding gates. Its safety pivot gate, which the company describes as patent-pending, is a good option for pallet traffic since only one side opens while the other remains closed. The gate is available in 12 standard sizes with a safety yellow powder-coated finish.
Are the components being specified as a complete system?
Gates, handrails, stairs, ladders and flooring can all be specified as a system that takes into account the structure’s design load and intended use. Cogan not only offers installation instructions for its stairs, ladders, handrails and gates, but also states that it cannot be held responsible for material or installation deficiencies in flooring purchased by others.
Customers should always consult their local building inspector for applicable codes and standards. The components page on Cogan’s website includes links to OSHA requirements for stairs and ladders, as well as the IBC.
