Employees in material handling and manufacturing are often at risk of falls when they are on the job. Recent figures show approximately 20,000 serious injuries and nearly 100 fatalities a year in industrial facilities.<ref>{{Cite web|url=http://www.mmh.com/article/industry_group_seminar_focused_on_safety_in_the_warehouse/safety|title=Industry group seminar focused on safety in the warehouse|website=www.mmh.com|access-date=2017-09-15}}</ref> Falls of people and objects from mezzanines are of particular concern.<ref>{{Cite news|url=https://www.mhisolutionsmag.com/index.php/2016/12/16/edge-protection-keeping-your-facility-safe/|title=Edge Protection: Keeping Your Facility Safe {{!}} MHI Solutions|website=www.mhisolutionsmag.com|language=en-US|date=2017|issue=Q1 |last=Feingold |first=Jean}}</ref>

In many industrial operations, openings are cut into the guardrail on mezzanines and elevated work platforms to allow picking of palletized material to be loaded and unloaded, often with a fork truck, to upper levels. The [[Occupational Safety and Health Administration]] (OSHA)<ref>{{Cite web|url=https://www.osha.gov/SLTC/fallprotection/standards.html|title=Safety and Health Topics {{!}} Fall Protection - Standards and Policy for Non-Construction Work {{!}} Occupational Safety and Health Administration|website=www.osha.gov|language=en-us|access-date=2017-09-15}}</ref> and International Building Council (IBC)<ref>{{Cite web|url=https://www.iccsafe.org/codes-tech-support/codes/2015-i-codes/ibc/|title=IBC {{!}} ICC|website=www.iccsafe.org|language=en-US|access-date=2017-09-15|date=2015-03-20}}</ref> have published regulations for fall protection and The [[American National Standards Institute]] (ANSI) has published standards for securing pallet drop areas to protect workers that work on elevated platforms and are exposed to openings.

In most cases, safety gates are used to secure these openings. OSHA requires openings 48 inches or taller to be secured with a fall protection system.<ref>{{Cite web|url=https://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9715|title=Ladders. - 1910.23 {{!}} Occupational Safety and Health Administration|website=www.osha.gov|language=en-us|access-date=2017-09-15}}</ref> Removable sections of railing or gates that swing or slide open would be used to open up the area and allow the transfer of material, and then close once the material is removed. However, current ANSI standards require dual-gate safety systems for fall protection.<ref>{{citation |url=http://www.mhi.org/free/9296 |title=Specification for the Design, Manufacture, and Installation of Industrial Stell Work Platforms|author=Storage Equipment Manufacturers Association|date=2009|publisher=MHI}}</ref>

Dual-gate safety systems were created to secure these areas, allowing a barrier to be in place at all times, even while pallets are being loaded or removed. Dual-gate systems create a completely enclosed workstation providing protection for the worker during loading and off-loading operations. When the rear-side gate opens, the ledge gate automatically closes, ensuring there is always a gate between the operator and the ledge.
