OSHA says that falls are among the most serious hazards associated with scissor and aerial lift use. Unfortunately, there are no general industry standards that specifically address this issue, but OSHA does provide guidance in various Letters of Interpretation (LOIs), publications, and the construction standards. Employers can elevate their understanding of scissor and aerial lift fall protection by thoroughly reviewing this information.
Scissor vs. aerial lifts
There are numerous types of 'lifts' used in industry, and it can be confusing for employers. Per OSHA, a scissor lift is a mobile scaffold for which the platform only moves vertically. An aerial lift is any vehicle-mounted work platform that can move vertically and/or horizontally. Some aerial lifts can even rotate around a vertical axis.
Aerial lifts are used to lift workers to difficult work positions that aren't able to be accessed by other equipment, even scissor lifts. This is also why aerial lifts are extremely hazardous. Lifting a worker up and out can make the lift extremely unstable if not operated correctly.
The use of both scissor and aerial lifts inherently presents fall hazards to workers. As such, understanding the basic difference between each helps ensure that you're implementing the correct safety measures in your workplace. This is particularly critical regarding fall protection.
General fall protection
OSHA says that employers should ensure that workers adhere to the following general fall protection measures when utilizing scissor and aerial lifts:
Personal fall protection
OSHA addresses the use of personal fall protection on scissor and aerials lifts in several LOIs. The protection is different for each lift. The reason for this is because the design and function of a scissor lift is different from that of an aerial lift, thus posing varying degrees of risk for falls.
Scissor lifts
In an August LOI, OSHA says that a scissor lift is a type of scaffold. In this letter, the agency states that if the scissor lift has guardrails that meet OSHA requirements, then this is all that is required for fall protection. In other words, workers do not have to be tied-off if the scissor lift has a properly designed and maintained guardrail system. The guardrails themselves serve as the necessary fall protection.
Aerial lifts
Fall protection for aerial lifts is different. OSHA's general industry aerial lift standard at .67(c)(2)(v) requires that a body belt be worn and a lanyard attached to the boom or basket at all times to prevent an employee from falling out, or being bounced out of the aerial lift. Body belts are only allowed for fall restraint and fall positioning systems as a means of fall prevention. A full body harness is required for fall protection.
Belting off to an adjacent pole, structure, or equipment when working from an aerial lift is not allowed per .67(c)(2)(iii). This does not, however, prohibit employees from exiting or entering an aerial lift basket that rests on or adjacent to an elevated surface. In these instances, the Agency says that fall protection requirements apply as explained in a May 3, LOI.
OSHA requires fall protection at four feet above a lower level at .23(c). A worker may enter or exit an aerial lift (at heights above four feet) provided that fall protection such as guardrails or a fall arrest system is used while the worker moves between the lift and the working surface.
Conclusion
Despite OSHA's effort to educate employers, scissor lifts and aerial lifts continue to present a number of safety challenges, especially falls. Although there are many factors that contribute to falls, most injuries are the result of falls to a lower level that many times involve equipment, including scissor and aerial lifts. Fortunately, you can safely guard against this hazard by understanding scissor and aerial lift fall protection and implementing the required safeguards.
Ever wondered about the differences between scissor lifts vs. aerial lifts? Both types of forklifts are essential to the modern construction and logistics industries. The key difference between these lifts lies in their functionality. A scissor lift is a type of aerial lift that allows workers to complete tasks at heights. But, the lift moves only up and down. Comparatively, an aerial lift can move in different directions. It also comes in many forms.
Scissor Lift vs. Aerial Lift: What's the Difference?
Aerial lifts and aerial scissor lifts are more alike than they are different. Even aerial work platform workers often fail to understand what makes each piece of equipment unique. Ultimately, the differences between scissor lifts vs. aerial lifts come down to OSHA definitions.

OSHA defines an aerial lift as a machine used to lift workers. An aerial lift lets operators complete tasks at heights. In addition, the machine should only be used by an OSHA-approved operator. Otherwise, an unlicensed aerial lift operator risks operational or maintenance errors that can lead to accidents, injuries, and fatalities. Aerial lifts are frequently used for construction, maintenance, by those working on power or lines, while fighting fires in tall structures, for window washing, during safety inspections, and for orchard and tree care.
A scissor lift is similar to a standard aerial lift. This type of lift can move workers and equipment vertically. As such, a scissor lift enables operators to safely access work areas that commonly require a ladder, tower, or scaffolding. Professionals rely on scissor lifts to repair signs, clean gutters, provide safe access to high shelves, and for routine maintenance chores.
It pays to know the similarities and differences between scissor and aerial lifts. Regardless of the type of lifts used across your business, your workers need OSHA-approved certification training, too. This training verifies that your employees know how to use different types of aerial lifts. It also confirms that your workers can do their part to identify scissor and aerial lift hazards and address them right away.
What is an Aerial Lift?
OSHA's aerial lift definition is the same as the one from the American National Standards Institute (ANSI), which considers the following vehicle-mounted rotating and elevating platforms as aerial lifts:
' Vertical towers
' Aerial ladders
' Articulating boom platforms
' Any combination of the above
Aerial lifts, or boom lifts, are classified as vehicle-mounted devices used to elevate personnel. They can lift workers both vertically and horizontally to reach exterior building structures, windows, trees, and power lines. They can be articulated to reach up and over structures, as well as access the top of roller coasters. The difference between an aerial lift and a scissor lift is that scissor lifts can only extend horizontally, and do not have the same reach power.
Think of aerial lifts as a more versatile elevated work platform. Aerial lifts, unlike aerial scissor lifts or vertical scissor lifts, are typically used outdoors. However, they're also used in some indoor facilities, such as heavy equipment manufacturing centers.
What is a Scissor Lift?
Just what is a scissor lift, exactly? They do not fall within any of the above categories of aerial lifts, nor are there any OSHA provisions exclusive to scissor lifts. They do, however, meet the definition of a scaffold. Unfortunately, if you look at the general requirements for scaffolds (§.451), you won't find scissor lifts mentioned. Anywhere on the page. Luckily, OSHA has made some improvements with their Scaffolding eTool. This page on the OSHA website makes it easier to understand what is a scissor lift and where it falls within the standards. It gives industry professionals some helpful background information on what makes a scissor lift.
According to OSHA, scissor lifts are 'mobile supported scaffold work platforms used to safely move workers vertically and to different locations in a variety of industries including construction, retail, entertainment, and manufacturing.' Unlike aerial lifts, scissor lifts can only move vertically, directly above the base. It's the recognizable criss-cross style beams that move the lift platform straight up and down.
All scissor lifts are considered scaffolding, whether it's a vertical scissor lift or aerial scissor lift.
Additional differences between what is a scissor lift and an aerial lift are the use of fall protection. OSHA requires that operators use body harnesses and lanyards on aerial lifts at all times, but these personal protection tools aren't requirements for scissor lifts. As long as there are functioning guardrails present, scissor lift operators don't need to wear harnesses while on the platform. This applies to aerial scissor lifts and vertical scissor lifts.
Why Use a Scissor Lift vs. an Aerial Lift?
Both of these unique tools come with their own pros and cons. Scissor lifts are simple to use and easy to move from one location to the next. They're also easy to operate and can be used in diverse work environments ' including the outdoors. Scissor lifts have bigger platforms, allowing more than one person to safely work on the lift at the same time. They're cheaper than aerial lifts and are easier to store.
Aerial lifts, on the other hand, can reach up and around structures to access even the most difficult of areas. They can work at heights of 180 feet or greater. They allow workers to perform their duties safely, even on rough or uneven terrain. Small platforms mean operators can work in tight areas, and the ability to extend long distances horizontally allows for even more versatility.
The Importance of Aerial Lift and Scissor Lift Safety
Perhaps the most important difference in scissor lifts vs. aerial lifts is their operation. Each lift has unique safety standards that operators must follow in order to prevent accidents. A little education can go a long way in keeping workers safe on the job.
