Safety is an important factor to consider when operating scissor lifts, like with any other equipment.
So in this article, youll learn:
Lets dive in!
What Is a Scissor Lift?A scissor lift is a piece of equipment with a rising and lowering platform thats used to move personnel vertically.
Scissor lifts get their name from their working mechanism.
That is, a stack of crossed scissor-like tubes (X-pattern) that raise and lower the platform.
No.
Per OSHA, a scissor lift is technically scaffolding.
More specifically, theyre mobile scaffolding equipped with a platform that only moves vertically.
On the other hand, an aerial lift is any vehicle-mounted work platform designed to move vertically, horizontally, or both.
The most common lifting heights for scissor lift are 19-feet and 26-feet.
But some models can go higher.
For instance, Snorkels SRT-HC scissor lift can raise a whopping 70-feet!
Scissor lifts are not designed to carry loads like a forklift or telehandler is.
Instead, theyre designed to carry only workers, tools, and some light materials.
Thus, their weight lifting capacities are generally limited.
On average, smaller lifts (like 19- and 26-foot models) can lift up to 500 lbs.
But other, heavier-duty scissor lifts can lift up to 4,000 lbs.
What Is a Scissor Lift Used For?Scissor lifts are almost synonymous with construction sites and facility maintenance applications.
But several other jobs use scissor lifts.
Here are some of the industries and tasks that scissor lifts are used for:
What Is the OSHA Standard for Scissor Lifts?
OSHA has several standards that cover scissor lifts.
These include:
Of course, you can review each standard yourself to learn the specifics.
But if youre looking for a brief overview, the OSHA scissor lift requirements broadly focus on training, hazard awareness, repairs and maintenance, and safety procedures.
This includes:
Now, OSHAs standards are not the only rules for scissor lifts.
ANSI (American National Standards Institute) also sets industry standards for scissor lifts.
If youre not familiar with ANSI, its a private, nonprofit organization that creates industry standards for aerial working equipment.
OSHA, on the other hand, is the government agency tasked with ensuring workplace safety.
Now, OSHAs standards are law.
ANSIs standards, meanwhile, are voluntary industry regulations.
So does that mean you dont have to follow ANSIs standards?
Not necessarily.
Thats because OSHA often incorporates ANSIs rules into its standards.
Effectively, that makes them the law.
Furthermore, disregarding ANSIs scissor lift rules can put you in violation of OSHAs General Duty clause.
This clause states that employers must keep their workplace free from recognized hazards.
So, you must understand and follow both OSHA and ANSIs rules.
How Safe Are Scissor Lifts?Scissor lifts are safe and reliable as long as theyre used properly.
But, when misused, scissor lifts can present serious safety hazards to workers.
In fact, OSHA noted 10 deaths and 20 severe injuries involving scissor lift accidents in a single year.
Knowing the top scissor lift hazards can help prevent deaths and injuries.
OSHA classifies the following as the biggest preventable causes of scissor lift injuries and fatalities:
Lets discuss these hazards in detail below.
Scissor lifts must have guardrails to prevent workers from falling off the platform.
To ensure scissor lift guarding and fall protection, operators must:
Always check guardrails systems condition before operating the scissor lift
Never stand on the guard rails (only stand on the lifts work platform)
Never lean over the guardrails or away from the lift to reach tasks (work only within reach)
A common question is: Do you need a harness on a scissor lift?
Answer: Not necessarily.
To explain, lets focus on OSHA scissor lift harness requirements.
OSHA states that scissor lift operators must be protected from falls from heights.
But doing so only requires a guardrail that conforms to OSHAs standards.
If thats the case, operators do not need a safety harness.
But if the guardrail isnt up to par, then a harness is required.
Another common question is: Can you use a ladder on a scissor lift?
Answer: No.
Using a ladder, planks, buckets, step stools, or any other device on the lift platform to extend your reach can cause you to fall over the guard rails.
You might be wondering: Can a scissor lift fall over?
Yes, if its not properly stabilized.
Thats why scissor lift stability is essential for operator safety.
Heres what they can do to prevent a scissor lift tip-over:
Follow the lifts manufacturer instructions for safe movement
Isolate the lift from worksite traffic and other moving equipment to prevent potential impacts
Only operate the lift on firm, level surfaces away from potential instability hazards. These include holes, slopes, bumps, drop-offs, debris, or other ground obstructions
Only use the scissor lift outside when weather conditions allow. The allowed weather conditions are on the operators manual
Keep the weight on the lifts work platform below the manufacturers rated limit
Ensure proper maintenance of the safety systems that stop the lift from collapsing
Yes provided the manufacturer allows it.

To determine if thats the case, check the owners manual.
For instance, the operators manual for a Genie GS- scissor lift states:
Do not drive over 0.5 mph / 0.7 km/h with the platform raised.
How you position your scissor lift has a lot to do with scissor lift safety.
After all, scissor lift operators are exposed to hazards like crushing and electrocution.
This is why operators should be cautious when:
Operating the lift near a fixed or stationary object
Using the lift close to a moving or mobile equipment
Moving the scissor lift below fixed objects like ceiling beams or door frames
To prevent electrocution, its recommended to:
Operate the lift in locations not near electrical power sources. For instance, dont use scissor lifts within 10 feet of energized power lines
If operators must work near power lines or electrical sources, ensure that the worker is properly trained and has certified electrical training
Use ground guides and traffic control to prevent other workers or move items (like vehicles) from getting too close to the lift
Do I Need Training to Operate a Scissor Lift?
Yes, you do.
According to OSHAs scissor lift certification requirements, you need scissor lift safety training from a qualified trainer.
If you dont have the resources or the desire to conduct scissor lift training in-house, you can always outsource it to a reputable training center.
If youre conducting in-house scissor lift training, ensure your training follows OSHAs guidance, including:
You can read the full text of OSHAs scissor lift training standards here, here, and here.
Besides OSHAs scissor lift rules, youll also need to incorporate ANSIs updated scissor lift standards into your training.
Well cover that below.
In December , ANSI updated the A92 standard for aerial lifts, including scissor lifts.
What does the update mean to you?
If youre a scissor lift owner, user, supervisor, or operator, it means big changes to training and safety.
While there are quite a few changes, the main ones are:
Employers must develop and document a safe use program specific to scissor lifts
All operators previous scissor lift training is now null and void, and they need to be re-trained under the new standards
All supervisors who oversee personnel operating scissor lifts need to have specific supervisor training
All platform occupants must have a basic level of knowledge to work safely on scissor lifts, including how to operate the controls in an emergency

Whats Involved in Scissor Lift Maintenance?Scissor lift maintenance is important for both operator safety and the longevity of the machine.
Keeping on maintenance will grant you many benefits, including:
Improved safety
Better performance
Extended service life
Improved productivity
Reduced downtime
Lower repair cost
Scissor lift maintenance should consist of both scissor lift inspections and preventative maintenance.
Lets cover each.
How often should you conduct scissor lift inspections?
Answer: Inspect your scissor lift every day before use, at shift changes, and whenever a new operator starts using the machine.
Doing so helps avoid putting employees and the machine in danger.
Along with inspections before use, operators should also assess the lifts after use to verify the scissor lifts condition.
These two aerial lift inspections allow the opportunity to resolve any problems before the next use.
Every manufacturer provides specific inspection items for their scissor lifts.
So you should always consult the owners manual to find out what those are.
That said, most inspections will focus on:
Any leaks (oil, fuel, or battery fluid)
Dents, cracks, or comprised welds
Pneumatic, electric, and hydraulic systems
Instructions, written warnings, and placards
Mechanical fasteners, harnesses, and locking pins
Insulating components
Guardrails, cables, and wiring
Outriggers and stabilizers
Loose or missing parts
Other than inspections, you need to perform regular preventive maintenance and follow the required scissor lift safety rules.
These inspections are based on the hours in operation.
A qualified equipment mechanic should inspect the scissor lift every 150 hours or 3 months, whichever comes first.
Additionally, youll need to perform an annual inspection no later than 13 months after the prior one was done.
Preventative maintenance checks should include:
Checking all fluid levels. This includes engine oil, coolant, fuel, hydraulics, and keeping an eye out for any leaks
Checking tires and wheels. Look out for worn tire treads and bubbles or cracks in the sidewalls. Check if tire pressure is at the correct PSI
Evaluating the lifts guardrails position and verifying that theyre strong and sturdy
Performing battery maintenance on electric units. Check the battery charger and make sure it has a full charge
Testing the braking and steering system to ensure theyre fully operational
Making sure all the machines safety gear is in place and in good working condition. This includes fall protection, safety harnesses, and reflector jackets
Testing all of the machines emergency controls. This includes the horn, lights, backup alarms, and gauges
Checking the scissor lifts stability. If the lift feels unbalanced or is on uneven terrain, dont use it
Using manufacturer-approved replacement parts
Additionally, you should keep a detailed history of the lifts maintenance records.
